I have seven grandchildren and one great-grandchild, but so far, none of them are interested in microwaves, machining, electronics, CAD, Physics, Maths or even quantum chromodynamics. There is still time though! Thanks for subscribing. Next video should be live in about two hours
@@KD2HJP Welcome to the warren! My list of future planned videos is now more than fifty, so that should keep me busy for a while, and provide plenty of burrow-following opportunities.
@@MachiningandMicrowaves This project is right up my alley. Only problem is I am not a machinst, but I am a total uhf to microwave as an amateur radio operator is like a warm snuggie blanket. I clicked and belled the algorithm overlord 73

This video is interesting, informative, well-shot, well-edited and very funny! Subscribing straight away and I’ll be going through more of your older videos. I also am fascinated by the microwave radar stuff.
Thanks, I'm having a lot of fun making the vids, although I'm rubbish at editing, filming, lighting, sound, transitions, machining and tidying. Apart from those minor items, and a lack of software skills and sleep, I've got a lot more vids in the pipeline to unleash upon an unsuspecting world.
How have I not found this channel before? This is really interesting! I was born in the 60's and I'm very "unit ambidextrous", I learned metric at school (in Australia), but my father and grandfather used imperial at home so i had learned to convert in my head before I was 10. We changed from miles to km when I was a young boy but my 2 of my first 3 cars were in miles. When I started my apprenticeship all the machines were imperial, but at trade school all of the machines were metric. And the man who taught me all about radio taught me "megacycles" before I knew they were supposed to be called megahertz.
I remember GHz being known as kilo-mega-cycles by some of the old timers I used to know in the middle 1970s when I was messing with 10 GHz Gunnplexer transceivers and varactor multipliers and bare-diode mixers. I'm still messing with multipliers and bare diode mixers, but at 135 and 248 GHz. Everything is less than a tenth of the size of what we used to mess with back in the dim and distant past, but just as much fun. I have very limited time to make vids, but I have a list of more than sixty that I want to make now, there's ten more in the list since 2 am local time today. John Hazell and friends down in the south of England have been using Hellschreiber visual mode on 122 GHz ruclips.net/video/_hAaYinsG64/видео.html
@@MachiningandMicrowaves very interesting! I've always wanted to play with those car radar devices, but I don't have that much time to play with radio anymore (at least outside of work). When I was active in amateur radio I was mainly interested in VHF and up and even made an EME (Earth-Moon-Earth) contact. I'm actually a Fitter & Turner (and worked in that trade for 11 years) before owning a business installing & repairing 2 way radio and satellite systems in the 1990's, For the last 23 years I've been a Broadcast Engineer in commercial radio - although the company I work for outsourced all of our RF work 3 years ago. I'm looking at getting back into radio at home when I get some more time!
I was born in the US, Iv always had to at least be somewhat comfortable with other units, starting in working on Japanese motorcycles and whatnot. Not as fast to convert as I once was but I still don't get it when people get so upset about not including certain units.
@@miles11we The funniest attempts are when someone does a literal conversion of an approximate value, so "roughly 2 pounds (907 grams)" or "two or three miles (3.22 to 4.83 km)". Of course, we do have to be very careful about gallons, pints, quarts, hundredweights and tons between UK and US systems. That has led to some very funny arguments about fuel efficiency or vehicles, when the US measurements use different sized gallons. Marvellous!

I rarely watch videos at 1x speed anymore because I rarely have the time, but this was 100% worth every second of watching. Informative, entertaining, and oh so satisfying 🤤🤗. Subscribed!
I try to strike a balance between sped-up sections and outright machining pr0n at normal speed. I know it's terribly fashionable to remove all spaces in speech, but wherever possible, I to trim out unnecessary words instead. I curate the clinks and clatters of tools and parts being moved very carefully. Around 80% of all footage end up being ditched. I like the sound of longish sentences, but sometimes I'm on the verge of running out of breath, so I have to break things up. I'm a rank beginner at this nonsense and there are things I want to do that I can't because I lack the equipment for nice tracking shots and smooth, quiet zoom pulls, but I'm working on the principle that if I can watch it through five times without hating it, and I think my mother will enjoy it, then it's ready to post. My life is a comedy, so I'm rarely going to be serious, and as soon as I start to think I'm doing something educational, it will be time to stop. Or make a second channel where I rant about Physics, or my dysfunctional relationship with all that lovely cybersecurity nonsense I mess with professionally. This is going to remain about me having a wild time designing, making and testing stuff that is about as niche as a hobby can get.
I've just gotten into HAM and I guess the algorithms brought me here. I'm very happy they did as I already love machinists. Subbed, liked, AND I watched the whole video.
Dangerous things, algorithms! I have a lot of videos in the pipeline that are a mix of radio and machining, some that are mostly machining, some that are mostly radio, but I hope they'll all be interesting. I'm just so slow at editing. Perhaps I'll get better with practice.
@@MachiningandMicrowaves practice makes perfect. You put on a fantastic show! Don't give up, you're more than just making videos, your teaching people too!!
Incredible work! I was thinking about the instrumentation to calibrate at this frequencies. As a technician who worked with C and L bands handling those HP spectrum analyzers was a big responsability due to their high costs.
Most instruments stop around 110 GHz, but as we are interested in maximising the far-field and directivity of the antennas, up to a point the S parameters, return loss and bandwidth/frequency behaviours are less important and we can concentrate on bulk characteristics like the received signal strength at a remote location. It's possible to use harmonic mixers, but my simple home lab equipment only covers up to 50 GHz and that's a simple spectrum analyser. Luckily, the radar chips have all of the SHF components including the antennas integrated into the package, so we are not dealing with anything more than about 2 GHz outside of the chip and in fact we run an IF of 144 MHz for convenience. Some of the instruments out there are certainly about the same cost as a house. I'm just working on an EM solver model of a tiny choked feedhorn, 3.8 mm diameter with a 1.8 mm core and a choke ring 0.5 mm wide. Machining those is certainly fun. For certain very carefully defined values of "fun", obviously
Just found your channel and now binge-watching your videos! When I was doing my master's in physics I had the university machine shop make me several microwave cavities with intricate internal geometry out of OFHC copper... Just realizing now how painstaking it must have been for the poor machinists. Hope they didn't curse me too much!
Oh, but just think of the fun they had making up new curse-words especially for you! I'm having a self-inflicted nightmare making the smallest antennas I've ever attempted. Designed to give -11dB edge taper on an f/d 0.4 prime focus parabola, 3.6 mm outside diameter with a tapered waveguide from 2.00 to 1.80 mm in Tellurium copper and a face choke groove 0.5 x 0.6 mm with 0.2 mm walls. Definitely at the "interesting" end of what I can make on this 1 ton slab of old cast iron and 1950s tech. Still, I'm 1950s tech so it seems fair enough.
Tony is ten levels of awesome above us mere mortals. I'm beginning to grasp the immense amount of work he must put in to each shot. The lighting is always perfect, timing impeccable and effects to die for. My hope is to get 1% better in each video, but that's logarithmic, so it will take me most of the rest of the century to get any good.
I have the heart of a machinist, the soul of a woodworker and a pile of attempted projects that shows that I sometimes have the hands and brain of a monkey with tools. Anyway, you had me at “all the words in your channel description”. The moment a bunch of cut edits of constructed waveguides turned into a stop-motion waveguide parade was enough to earn my respect and subscription. The production value and humor are icing on the cake. A nod and a wave (guide) from Texas.
Outstanding content, thank you! Now that I’ve learned not to attempt drinking anything I don’t want spraying out of my nose while watching your videos…I’ll be getting caught up on the rest of your stuff-just subscribed ✅👍
@@MachiningandMicrowaves dang it man! Now you have me using Google translate on what you typed...translated from Albanian it reads " ready your soldiers for in 7 days the subterranean lizard men shall arise to conquer the world "😜 You should join/ guest star on the 'safety third ' podcast technical, nutty and funny enough to fit in!
I think most of the vids will have a bit of each, but some are more machining for things that can be used to make other things that are used to make microwave things. Some of the other vids will be about microwave propagation and physics and antennas and waveguides but almost always using parts that have been machined. So I thought the channel name was a reasonable description. I could have called it "Neil has an unfeasibly huge amount of fun messing about doing his hobbies", but that might involve my OTHER hobbies. Like being a willow basketmaker or carpenter of green-oak framed buildings, or dressmaking, or wild gardening or... well you get the idea. Hmmmm, a basketmaking channel might go down very well with the ASMR folk.
Seen the post on hackaday, wasn't expecting the antennas to have this shape, reminds me of a school project when some dude tried to make rocket engines out of 6061-T6, of course they all blew up but he spent whole lunches in the machine room, nice effort.
@@robbiejames1540 Bit lighter than Inconel I guess. I've never played with rockets, but one of the RUclipsr rocketeers is trying to use servo controller vectored thrust to do a Spacex-style soft vertical landing and I had thoughts of using three solid rocket engines which can be moved outwards under servo control in lieu of a throttle to reduce the effective thrust and control direction. Must Not Start Any New Projects.....
@@MachiningandMicrowaves Funny thing - I'm currently trying to build a rocket engine, but after watching your video I was practically chanting "no new projects" to stop me from immediately heading off and trying to make radars :) Thanks for the very interesting video.
I remember when Dad did something like this in the 50's. He had a 500mm (there abouts - silly millimeter or two) a vacuum tube (valve ?) amp and all. He was snagged by the local law and went before the judge. He showed his Advanced Radar with an unlimited note on it - but the judge didn't recognize the FCC and Automobiles. Dad took it off but completed his tube (there I go again) timing system for our car. He was something else if you put him in an EE or ME shop. I have his lathe now.
Drilling the 1.8 mm diameter holes 48 mm deep with long-series drills really shows up any offset or concentricity errors in the tailstock or chuck, or bends in the drills. I start the holes with a 1.6 mm centre drill and use a smaller high-precision chuck, and check the tailstock position regularly, plus I always clean the bore of the Morse Taper in the tailstock with a sheepskin-covered bore wiper and clean the taper of the chuck carefully.
Although making a wooden box would beyond the scope of my capabilities, I greatly appreciate the effort, time, editing and sense of humour! Thank you for making these topics approachable for a simple colony boy!
Lots more to follow, although I have a huge pile of machining and electronics jobs to get finished and shipped out and I'm sitting here at 3.30 am local time editing a video. Good job I'm not at work tomorrow at the salt mine, I get to sleep late and play with my Chihuahuas instead of pressing keys to change patterns of light on a screen, which is basically what my chosen career has consisted of for the last 37 years or so.
As a kid, I watched an awful lot of Top Cat, Tom and Jerry, Roadrunner and all that Looney Tunes/Hanna-Barbera stuff, so that's my sound-world, along with anthropomorphisms and personification of inanimate objects with thoughts, feelings and voices. Dropping something simply HAS to make an unfeasible CLANG, and of course a toolbit should giggle when it's being sharpened, and an old lathe should obviously complain about its aches and pains. Hammers should make a proper THWACK sound, with a Batman-style BLAM! or KERPOW! ruclips.net/video/NZaG_13ZIYY/видео.html
Well done! I found your videos while looking for a magnetic lathe chuck and now I find that you're into microwaves, radar and such. Those are other, professional areas of interest for me. Love your assistant AIMEE....she'll keep you straight! 👍
She's fierce! I'm just trying to get hold of something like the Simturn E3 grooving cutters to make an aluminium mandrel for a corrugated feedhorn at 122 and 135 GHz. I'll then give it an etch and zincate coating, gold electroplate, then nickel, then a thick layer of copper electroformed and finally boil it up in sodium hydroxide to dissolve the aluminium, leaving me with a gold-coated corrugated horn with extremely low sidelobes, and great axial symmetry, but also, breathtaking bling and wizardry to impress my mother. Who watches this channel. Hi mum!
Thanks for watching. Next step in that project will be the subject of a video in 2-3 weeks time. Making a range of dual-mode feedhorns to fit into those adaptors. Absolutely tiny features, with 0.5 mm grooves and 1.8 mm tapered bores. Huge fun using an ancient 800 kg cast iron metal-basher to make antennas so small you can lose them in a trouser pocket, or blow them off the bench if you sneeze.
Machinework is serious business. No laughing, unless it is a co-worker turning on the spindle and launching their test indicator across the room to strike the clock and break it.
Tony's hands went to Drama School. So expressive. I am not worthy even to wave my hands vaguely in his general direction. Observant listeners may discern a pattern in which of my fingers has a sticking-plaster in each of my videos. There's probably a Hidden Code or something. Spike Milligan's Q series on TV could be the inspiration behind that. Or it might be entirely a random occurrence. PhDs will be written about the subtextual nuance of the pattern. Academic careers will flourish. It'll be another "Rosebud" for sure.
I have absolutely no experience, education, etc. in radar, but this video has piqued my interest. So you know, I am a licensed pest control technician and have interests in electronics, machining and Isuzu. You've earned my subscription.
I hope I can keep everyone interested, I'm fascinated by all sorts of things. I've been working on some new antennas only 3.6 mm diameter and 30 mm long this evening, with a 0.5 mm groove 0.7 mm deep in the face. I'm using a lathe that weighs almost 2000 pounds. The part weighs less than half an ounce
There's a huge amount of content I'd like to get filmed and produced, just not enough hours in the day to do it. Tonight's problem is taking the "electronic leadscrew" approach that James made, but using a really muscly 750 watt AC servomotor with an absolute encoder to drive the cross-slide, plus a hack of my DRO so I can make parabolic, hyperbolic and elliptic surfaces mirrors to work with microwave and mmWave antennas. Trying to design the mounting so it's impossible to engage the transverse leadscrew while the servomotor is active. I've been out in the garden with a green laser, translation stage and precision rotary table, trying to get the rear focus of a hyperbolic subreflector to be coincident and coaxial with the focus of a large parabola. That is going to be hugely challenging to film, but I just have to do it now I've had a dry run. Neighbours must think I'm having some sort of techno rave, but spookily quiet. I've been to silent disco events, where there are two DJs playing different tracks and transmitting them on two channels which can be received on selectable-channel headphones that all the attendees are issued with. Except I was listening to the level of a transmitted tone and trying to peak up the focus of the dish so the laser beams were parallel at 30 metres away. Honestly, the things I do for my hobbies!
The raw cut of the current video consists mostly of me swearing and invoking the Gods of Machining, and summoning various Daemons form the Pit. While that might be mildly entertaining, if I were to bleep out the expletives, the audio would just end up as a long string of Morse Code. Woah! if I said the right sequence of curse-words and bleeped them all, I could SPELL OUT something rude with the bleeps in Morse. Oh dear, that appeals far too much!
That's a good point. I try to remember to clean up any drill shanks that get messed up, but most of the holes I drill on the lathe are done with drills I keep specially for that purpose, for tap sizes or reamer pilots, or are non-critical. I guess I picked that habit up from watching my father rotating drills as he chucked them but never questioned what the real reason was. A 50-year mystery solved! Cheers!
Heh heh, now if only I could use a file and do layout like Chris does, and be any good at silver soldering or machining or blueing or spilling the blood of my apprentice for layout fluid. In my dreams.... Not the spilling of blood bit, obvs.
One of my project is making even smaller antennas with a hollow tapered horn that has fine ridges inside. Almost impossible to machine those, so I make an aluminium negative of the space inside, with sort of radial fins 1mm wide with a 1mm gap and about 3mm deep, then treat that with a zincate bath, removing the aluminium oxide and replacing it with a fine zinc coat, then without allowing the air to get at it, I rinse it and put it into a gold-plating bath, plate a few microns of gold, then nickel, then a very thick layer of copper. Once the copper is several mm thick, I machine up the outside of the plated area, drill out most of the aluminium, then dissolve the rest in a hot caustic solution. I'm left with an internally-corrugated tiny feedhorn which is gold-plated inside and electroformed copper outside. If I ever get the process fully debugged, that should make an interesting video.
@@IanBuckley The challenge is in trying not to eat the entire pack at one go. Haven't had a Fruit Pastille for 30 years. Now I want Fruit Pastilles, obviously.
Glad I stumbled upon your channel. Antennae, waveguides, and high-frequency RF are black magic to me. I like your informal approach to the subject without dropping a load of calculus on us straight away. Careful about that AI though -- she might be your overlord one day. 👍️
I'll keep the vector calculus and Messrs Hilbert, Fourier, Fresnel and others firmly locked away for a rainy day. I might start going on about how waveguide wavelengths get squished out lengthwise as the waveguide gets narrower, and how mad things like slot radiators work, but I might slip in some maths and physics by stealth where it adds interest
Excellent channel. Glad RUclips suggested again as I'm so down another rabbit hole in regards to... whatever they said... oh no collections or reporting... OK, sewing machines... albeit I can't help having thoughts of stitching fractal antennas for fox hunting with that more WW2 era look... thinking the WW1 era look was way more. For some reason I have thoughts of wearing hat sized whisper dishes in regatds to WW1. Thanks for sharing! Cheers!
Now THERE's a thought. I wonder if my sewing machine could be used to embroider wearable antenna elements or perhaps to sew them on to the surface of an inflatable bag? I can imagine Aimee would probably tell me off for getting sidetracked by yet another madcap scheme. Oh dear.
I'm trying to work out what noise the tiny ring of material left after parting off makes when it lands in the chip tray. I imagine something like a huge bell being dropped down a mine shaft. Hmmm, wonder if there are any royalty-free sound clips of that effect...
Lots of folks seem to be working on steam projects, I enjoy @MrCrispin96 Andrew Whale, @keithappleton @trainman4602 and everyone making Stuart engines, plus Lisa Milne (TiklishHoneyBee on Twitter). I'm more interested in clockmaking and watchmaking and radio stuff, and I've always fancied getting a stationary engine. My father worked at Ruston and Hornsby, and I'd like to get one of the 1930s models. I'm probably not ready to embark on building a steam loco - maybe if I ever get to retire!
@@MachiningandMicrowaves I am familiar with most of them but you have really got my attention. I'm a digital electronics guy, radio has always puzzled me. My father is a ham and was an electrical engineer at Motorola responsible for the cellular base station division. Unfortunately that radio engineering knowledge never trickled down to me. Greetings from Chicago btw.
@@GeeWillikersMan The really interesting detail is where you push beyond what you can design using Maxwell's equations and field theory by hand or rule of thumb and move into metamaterials and graded index lensing and unusual cavity resonances. I'm working on some models for axially-displaced ellipse antennas, which don't suffer from aperture blocking. That means using big AC servomotors with absolute encoders to drive the leadscrew and cross-slide on the lathe. I'm doing a lot of work on the mechanics and control systems for steering large moonbounce dishes to track the moon. Also messing with some non-radio electronics, but mostly PIC devices and linear microwave things like Gallium Nitride HEMT amplifiers. I do a bit of work with FPGAs using Verilog, but there just aren't enough hours in the day. I just noticed it's 1am here and I have to be at my desk in 7 hours....
I'm having a lot of fun, I've been converting the Spidermandrel to have optionally four jaws each end as well as three. Almost finished the machining and filming, but it's almost 1 AM and the village is VERY quiet, so my machining noise is probably going to annoy the neighbours. Time to stop for the night I think. It's interesting that I only use around 10-15% of the footage, and it takes me up to eight hours to make a 30 minute video at the moment. I hope I'm going to get faster and more efficient. I'm a total beginner at this nonsense. Neil
There's just so much interesting stuff to talk about in microwave/mmwave radio experimentation, I've already got a year's worth of ideas mapped out. Another upcoming project is building an az/el hydraulic moon-tracking system for my big 3 metre diameter General Dynamics solid parabolic dish so I can do moonbounce on 10 GHz. Lots of intricate control system engineering and I want to to remain usable in significant wind speeds. I've bought some Gallium Nitride devices that can run over 90 watts at 5.7 GHz, a pair of those would make a nice loud signal off the moon on 6cm. I'm working on a set of Pickett-Potter dual-mode feedhorns for 122 GHz with various different gains for one of the French experimenters who's trying to optimise the illumination/overspill of an offset parabolic dish. Lots of challenging stuff to do. I need to retire from the day job, or just stop sleeping!
I keep trying to get clean snaps when I karate-chop bits of 25 mm stainless bar, but all I get is bruises. As for that stuff he applies with an eye dropper along a scribed line on a bit of mild steel, I waited AGES and all that happened was rust. HOWEVER, my experiments with modified free energy machines and laser-pumped plasma gyrators for ablative machining are showing great promise. Assuming, of course, that I don't set fire to the shop. Again.
I don't know anything about microwaves beyond them being the key to quick porridge in the morning. I do, however, appreciate quality machining and humour. Subscribed. A hand based headless machining and humour channel..... you dont happen to have long lost relations in the U.S. do you? If I had to guess, I'd say they were called Tony.
I was a little concerned that I might get angry complaints about the lack of quick lunch recipes, no-stir cake-mix comparisons and of course, unboxing vids featuring the latest Samsung Hotblast or Panasonic Slimline models, but so far, the only manifestation of that is in the number of dislikes! If I could just approach Tony's level of skill in lighting, I'd be very cheerful. His level of performance and timing and special effects are the stuff of legends. When I try to replicate his telekinetic atomic cleavage operations, I just get abrasions and bruising and sadness,
This feels like it's got some This Old Tony, some Internet Historian (mostly the snarky TTS "assistant") and maybe some Styropyro? I can't quite put my finger on it but I DEFINITELY like it and am excited for future things to come! Also, if the parts didn't come out as desired, just blame it on forgetting to spinn the endmills while inserting them in the chuck. Also, why not solder the cavity to the board and using press-fit alignment pins? Too large of a risk of damaging the chip?
The boards were made at a PCB fab somewhere in China and shipped out by Tim Tuck from Australia, and they are designed to work with some aluminium horns that Tim had made. If I was starting at the PCB design stage, I would have to consider a fixture that could perhaps be glued to the chip surface. At these frequencies, 1.2 mm of metal looks like an insulator as it's a resonant halfwave, also the capacitance of the body to the PCB is several picoFarads, which at 122 GHz is perhaps half an ohm, so an electrical connection isn't really needed. To get the ultimate in performance, I think we'll need to use a pair of the chips, each with a carefully-optimised coupler, perhaps using a machined Rexolite 1422 cross-linked polystyrene dielectric lens to get the maximum possible performance out of the chip. There is another chip with two four-element patch aerials on the chip package, and that might be worth a try, I have a few of the chips, but I am thinking in terms of an XY translation stage with flexures to position the receive or transmit antenna at the sweet spot, as we don't need concurrent receive and transmit for our long-distance communication experiments.
I'd love to see what you could come up with for a fish finder. How sensitive you could get the radar part that detects the fish and how clear you could get the signal to show up on the graph. That may be something you can patten qnd get a nice payday with. Fisherman are always looking for better technology and getting the best advantage possible.
The difficulty is that radio waves don't travel far in water, maximum range depends on temperature and salinity, but is only going to be a a centimetre or so, which is why sonar is used rather than radar. Getting a high-resolution image from individual fish needs a wavelength of about 10 mm, and that means a frequency of something like 200 kHz from a piezo sender. Those usually reach 10 metres in clear water. If it was possible to have a large phased array of those, you could get a good 3D image, but fish are an awkward shape and contain a lot of water. Definitely an interesting challenge. Now finding fish IN THE AIR is a different matter! Getting fish airborne might be somewhat more challenging. Although.... ruclips.net/video/tLmJjRqXDCo/видео.html
@@MachiningandMicrowaves @Gregred78 Maybe a marine radar (or array of for imaging) to better resolve how those in the proximity or target locations are doing in regards to catching fish? OK, maybe not and far more expensive... though worth a try? :-|)
@@MachiningandMicrowaves You're going about it all WRONG sir... If the problem is that the radar doesn't penetrate far enough into the water, then surely the OBVIOUS solution is to simply get rid of all the water! Let me know when you've finished draining the North Sea!
@@MachiningandMicrowaves I've heard of water being named "The Universal Solvent", so perhaps it's not TOO much of a stretch to also name it a "Perfect Solution" too...
I was just copying what I saw my father do, but didn't realise it was more to do with avoiding offset errors caused by using drills with burrs from being allowed to spin in the chuck
The computer/machining joke about munging up "threads" is equally applicable to "files" no? Also I've seen a lot of machinists use shim stock as consumables rather than cheap gauge blocks. That said it would be one more thing to drop into the chip tray, and shimstock it a bit sharper than a carrot.
Heh heh, it's like real radio, but the parts are small enough to lose on your desk. Maxwell's equations still apply, the same as at VLF. Lenses become practical, but machining tolerances start to get very tight. These parts are quite large at 122 GHz with a wavelength of 2.44 mm. At 241 GHz, a waveguide tube is only 1 mm diameter and the surface roughness needs to be at the micrometre level. I use a video microscope to machine many of the parts, and a binocular microscope for assembly. Many of the tools and techniques are similar to those used by watchmakers. I have a licence variation that allows experimentation between 275 GHz and 1 THz. Now THAT is small stuff.
This is a great informative video. I am an electronics engineer with a fascination for machining and microwave radar stuff - just a fascination though, apart from measuring wave length with a sensor in a split wave guide at school and using them to excite water atoms I never used microwaves. Well... I did try one of those as cheap ass coffee radar sensors but liked them as much as cold coffee 😕
This is going to be a slow and steady reveal, I'm ideas-rich but time-poor. Storyboard number 58 just got added to the list of videos I want to make. That won't see the light of day this year I guess. Unless I retire from The Day Job. Must buy a lottery ticket!
Wouldn't it be great if this stupid camera had a filter ring or a viable way to hold a filter ring with a rubber boot or something? Talk about Buyer's Regret. It isn't the worst camera I ever owned, I've had a LOT of cameras, but it's the second-worst for sure. I have a mount that can take a 58 mm skylight or UV or whatever, but that then needs some sort of shroud to fix over the camera body to stop it seeing reflections. I guess these things must be useful for something, but it's just about unusable. The dial pad thing for focus is dreadful. If I hadn't spent so much on the horrible thing, I'd throw it away. If I can find a way to trade it for something that works, I'll definitely be doing that. Good points, the audio is fair, but the lack of a power input is unforgiveable, the focus is almost entirely useless except for selfies or vloggers. I have no idea what I was thinking when I bought it! Horrible. Sony ZV-1 #NotSponsored as Quinn would say.
Dude,.. I'm a RF engineer who loves machining and spends like 3h a day on RUclips for educational videos. How did it take so long to find this awesome content! Sub+1 :)
"Educational" might be a bit of a stretch goal. perhaps I could describe the taste of cast-iron dust that somehow got past my full-face visor and breathing mask and is crunching between my teeth. I'm sure some of it is in one of my socks. I must see if my fingernails now work like an iron-dust inductor core. Oooh, I could make a WILD Theremin or Ondes Martinot with capacitance AND inductance detection from my fingers as inputs. I did make a very silly musical thing that used doppler reflections at 47 GHz, but unlike a Theremin, which works on position and capacitance, this worked on velocity, so to keep a constant tone, your hand or table-tennis racquet had to stay at a steady speed. Rather brain-scrambling at first, and you can only do shortish notes, but it's a bit like playing a piano accordion or squeeze-box. Current status: Putting a rare-earth magnet in my boot and shaking it around to get the cast-iron bits out. Next step: put the sock and magnet in a poly bag and shake it like a Polaroid picture until the sock becomes useable once more. If it ever does.
@@MachiningandMicrowaves well. I can see that you're having some great ideas coming up here! Really looking forward to get this instrument to a proper use :D Go on with that stuff! Really appreciate and enjoy it.
Two magnetrons with each being out of phase 180 degrease with each other can transmit at vector of intersection waves . scalar ? tested with homade klystrons. im using a spent high pressure sodium arc tube for the electron emitter and using voltage multiplier with bismuth anode cathode style rings 16x .
Destructive interference isn't quite the scalar wave Tesla reported. Please look into phase conjugation/4-wave mixing in non-linear media, which normal antenna interference effects do not allow. Normally two sources of waves that are 180 degree out of phase will destructively interfere between sources, but there will also be constructive interference INSIDE the sources which results in HEAT. The "destructive" zone between antenna doesn't really destroy energy, it just moved it into the "constructive interference zone" at the boundary(the antenna). Same thing happens in noise cancelling headphones, sound waves are "destroyed" but the pressure at the speakers is now higher and so the speaker experiences hotter, high pressure air and the speaker magnet circuit experiences greater resistance to motion, and therefore higher heat losses. Now things get a little bit different with phase conjugation. "Time reversed" waves occur in non-linear media. These waves are almost perfectly equal and opposite to the phase, momentum vector, polarization and amplitude of incoming light because of the process of 4-wave mixing inside a holographic diffraction grating formed by the non-linear medium. This means instead of HEAT occuring in the material due to constructive interference of waves, a holographic image of the environment will be stored in the polarization of the electrons in the material. You could call this type of wave between objects "scalar" in a sense because it requires the vector components of the wave field between sources to be equal to zero. Quantum potentials such as the magnetic vector potential and the electric scalar potential however are NOT zero in between these types of sources and we can detect effects like the Aharonov-Bohm effect where magnetic B field and electric E field =0. Quantum potential effects occur even in the absence of Electric and Magnetic "force fields". Tesla may very well have discovered this effect with his pulsed DC experiments, which formed a sharp pulse of electrons and ions in the air, such a plasma double-layer accelerated has highly non-linear electro-optical susceptibility. Tesla later invented a non-linear shuttle oscillator circuit that modern microwave engineers are beginning to understand would explain a great deal of the unusually high performance reports of his "Magnifying Transmitters". It wasn't just destructive interference optimization, it was TWO PAIRS of photons, which are locked into a pair of phase conjugate mirrors. If the circuit acts as a non-linear signal mixer, it would be capable of phase conjugation of radiation, by dynamically altering the impedance of the circuit, and storing the wave energy in a matrix of capacitors which behave like a holographic image of the incoming waves, so that outgoing waves are phase conjugated and energy remains bottled up between two transmitters with almost zero losses to heat or scattering. This is why Tesla thought he had gotten longitudinal waves, which isn't exactly incorrect, it's just that quantum scalar potentials weren't considered "real" by scientists in Tesla's time until quantum mechanics showed the "A-field" has real physical effects on matter where no EM waves are "exposed". What I find most exciting about phase conjugation besides wireless power transmission, is how it could boost technology like "optical tweezers" and laser cooling. Basically the Sci-Fi kind of "force fields" become possible. The dynamic holographic effect that phase conjugation achieves allows mirrors to automatically resonate with a source of waves with almost no losses. Resonant cavity mirrors can store wave energy based on the Quality Factor of the mirror, High Q factor=high Gain. If a resonator can automatically lock on to objects then you don't need lenses or phase shifters. If your phase conjugate mirror can lock on to a bit of matter, and you deliberately pulse the signal like Tesla did, or you modulate the frequency, the off-resonance waves will not match the hidden "scalar" field which the hologram stores, so it will push or pull the object, depending on if it was Red-Shift or Blue-Shift. The hologram will lose energy proportional to the force on the object and the new hologram will attempt to lock on to the object again in the new position. Objects made of neutral matter, that are phase locked with the hidden "scalar wave", just as Tesla described, will experience a penetrating, uniform force, without much heating or scattering light. Already this technology is being explored by medical science to penetrate human body with low energy waves, which are conjugated by a phase conjugate mirror behind the patient, so that the time reversed waves return through the tissue backwards, to give a projection like an X-ray.
That sounds like quite some level of excitement. Nothing better than experimenting with potentially-lethal voltage and RF fields. Splendid! I think I'll stick to Gallium Nitride HEMTs though!
@@MachiningandMicrowaves Thank you for your video and your dedication to your work. Dualing Klystrons does sound rather dangerous and I'm afraid if he's after exotic interference effects he's going to have a lot of trouble, though he could make some fun toys, like a Wakefield accelerator if he aimed the output of both Klystrons at the correct angle through a gas cell. Semiconductors like Gall-Nitride, Gall-Arsenide and Barium Titanate are suitable for making switching devices above microwave frequencies, but did you know they're also capable of being externally pumped by radiation to form a phase conjugate mirror? The US government research into such materials for RADAR stealth aircraft led to an interesting discovery. Microwave resonances in certain ceramic materials leads to strong coupling, whereas off-resonant signals produce attractive and repulsive forces. A cube of Barium Titanate can be levitated above a Magnetron tuned below the resonance, the Redshifted waves mismatch the optoelectronic resonance frequency and induce a repulsive electromotive force. Phase conjugation can also be used to time-reverse signals, which can cloak an object by retro-directive destructive wave interference, which can also be used to obtain the location of the source of incoming, interrogating RADAR signals without giving away your own position. Research into RADAR absorbing materials and non-linear opto-electonics for stealth technology is therefore highly classified due to the weapons guidance and counter-RADAR potential. Furthermore field-effect propulsion technology would be incredibly disruptive to the global balance of power, but I believe that it is important to share that information across multidisciplinary fields in the scientific community because of the tremendous benefits to society it could bring, such as nearly lossless beyond-line-of-sight wireless power and data transmission.
The problem of using anything other than a perfect optical filter is that it causes blurring and flare and loss of contrast, plus if any light gets behind the sheet, it causes reflections. Other tha flinging this horrible camera out of a high window, it should be simple enough to machine a Delrin collar to fit over the lens body, then cut a filter thread for a 52 mm Skylight 1A or similar screw-in lens filter, perhaps in a brass ring that is fixed to the Delrin collar. Oh squeee! I think you've just given me a subject for another video. Cooler than a cool thing! Thanks v much.
On the other hand, how Steampunk would it be it it was all in brass with an O ring seal and stainless steel knurled clamps. I like this idea more every minute
I'm not sure what everyone is doing with these things but from my field, is there anything useful on a Rosemount radar level detector, for instance? Foxboro makes better and cheaper ones. When a plant get's upgraded, these kinds of things end up in a dumpster even though they are perfectly functional. Sorry, we use them for tank level in plants. Normally they are used in products that are caustic or foamy or splashy. There's also sonic ones but that's not what we're here about. The radars seem very powerful and they come with a horn that...I really don't know what it does but it has a one. Anyway just something that attracted me here.
The thing that makes these chips particularly interesting is the frequency they use, which is in a region of the mmWave spectrum where it's REALLY hard to find anything that can generate a signal at all, so when SiliconRadar brought out two different chips for the 122 GHz band, which is a part of the spectrum that amateur radio experimenters are licensed to transmit on without the limitations of type approval, folks got very interested. There are some vehicle radars in the 80 GHz range and others around 24 GHz. 80GHz is not in a very useful part of the spectrum, and there are lots of much better solutions at 24 GHz. SiliconRadar are also working on 134 GHz chips, which I guess are used for non-contact sensing. Those are of great interest as that band is much further from the oxygen absorption line around 119 GHz that limits the potential range that can be achieved. We are pushing these things way past their design parameters and having to find innovative ways to get around the limits. In the early 1970s, we did the same with the radar speed trap devices (Gunnplexers) at 10 GHz, and before that in the 60s with Reflex Klystron vacuum tubes, so this repurposing of tech has a long history. I love it because it's huge fun, I get to design stuff and make it and ship it off to friends all over the world so they can enjoy experimenting and pushing the limits of the Laws of Physics a bit.
So in general, there are some ex-equipment units that are really useful, like the Wavelab 23 GHz units that can be used on 24 GHz, but if there is anything useful in a detector there's probably someone somewhere who's found how they work and made a video or a blog post about it. I've not seen any mention of Rosemount or Foxboro units (so far!).

This video is interesting, informative, well-shot, well-edited and very funny! Subscribing straight away and I’ll be going through more of your older videos. I also am fascinated by the microwave radar stuff.
Thanks, I'm having a lot of fun making the vids, although I'm rubbish at editing, filming, lighting, sound, transitions, machining and tidying. Apart from those minor items, and a lack of software skills and sleep, I've got a lot more vids in the pipeline to unleash upon an unsuspecting world.
How have I not found this channel before? This is really interesting!
I was born in the 60's and I'm very "unit ambidextrous", I learned metric at school (in Australia), but my father and grandfather used imperial at home so i had learned to convert in my head before I was 10. We changed from miles to km when I was a young boy but my 2 of my first 3 cars were in miles. When I started my apprenticeship all the machines were imperial, but at trade school all of the machines were metric. And the man who taught me all about radio taught me "megacycles" before I knew they were supposed to be called megahertz.
I remember GHz being known as kilo-mega-cycles by some of the old timers I used to know in the middle 1970s when I was messing with 10 GHz Gunnplexer transceivers and varactor multipliers and bare-diode mixers. I'm still messing with multipliers and bare diode mixers, but at 135 and 248 GHz. Everything is less than a tenth of the size of what we used to mess with back in the dim and distant past, but just as much fun. I have very limited time to make vids, but I have a list of more than sixty that I want to make now, there's ten more in the list since 2 am local time today. John Hazell and friends down in the south of England have been using Hellschreiber visual mode on 122 GHz ruclips.net/video/_hAaYinsG64/видео.html
@@MachiningandMicrowaves very interesting! I've always wanted to play with those car radar devices, but I don't have that much time to play with radio anymore (at least outside of work). When I was active in amateur radio I was mainly interested in VHF and up and even made an EME (Earth-Moon-Earth) contact.
I'm actually a Fitter & Turner (and worked in that trade for 11 years) before owning a business installing & repairing 2 way radio and satellite systems in the 1990's, For the last 23 years I've been a Broadcast Engineer in commercial radio - although the company I work for outsourced all of our RF work 3 years ago. I'm looking at getting back into radio at home when I get some more time!
I was born in the US, Iv always had to at least be somewhat comfortable with other units, starting in working on Japanese motorcycles and whatnot. Not as fast to convert as I once was but I still don't get it when people get so upset about not including certain units.
@@miles11we The funniest attempts are when someone does a literal conversion of an approximate value, so "roughly 2 pounds (907 grams)" or "two or three miles (3.22 to 4.83 km)". Of course, we do have to be very careful about gallons, pints, quarts, hundredweights and tons between UK and US systems. That has led to some very funny arguments about fuel efficiency or vehicles, when the US measurements use different sized gallons. Marvellous!

Why are all machinists punny?
I rarely watch videos at 1x speed anymore because I rarely have the time, but this was 100% worth every second of watching. Informative, entertaining, and oh so satisfying 🤤🤗. Subscribed!
I try to strike a balance between sped-up sections and outright machining pr0n at normal speed. I know it's terribly fashionable to remove all spaces in speech, but wherever possible, I to trim out unnecessary words instead. I curate the clinks and clatters of tools and parts being moved very carefully. Around 80% of all footage end up being ditched. I like the sound of longish sentences, but sometimes I'm on the verge of running out of breath, so I have to break things up. I'm a rank beginner at this nonsense and there are things I want to do that I can't because I lack the equipment for nice tracking shots and smooth, quiet zoom pulls, but I'm working on the principle that if I can watch it through five times without hating it, and I think my mother will enjoy it, then it's ready to post. My life is a comedy, so I'm rarely going to be serious, and as soon as I start to think I'm doing something educational, it will be time to stop. Or make a second channel where I rant about Physics, or my dysfunctional relationship with all that lovely cybersecurity nonsense I mess with professionally. This is going to remain about me having a wild time designing, making and testing stuff that is about as niche as a hobby can get.
I watched it on 0.5 speed
Came for the millimeter microwaves, got mesmerized by the lathe work but subscribed for the snark.
Perfect!
I've just gotten into HAM and I guess the algorithms brought me here. I'm very happy they did as I already love machinists.
Subbed, liked, AND I watched the whole video.
Dangerous things, algorithms! I have a lot of videos in the pipeline that are a mix of radio and machining, some that are mostly machining, some that are mostly radio, but I hope they'll all be interesting. I'm just so slow at editing. Perhaps I'll get better with practice.
@@MachiningandMicrowaves practice makes perfect. You put on a fantastic show! Don't give up, you're more than just making videos, your teaching people too!!
Got a bit of This Old Tony of humor in this and really informative. Super happy I stumbled upon this channel!
Incredible work! I was thinking about the instrumentation to calibrate at this frequencies. As a technician who worked with C and L bands handling those HP spectrum analyzers was a big responsability due to their high costs.
Most instruments stop around 110 GHz, but as we are interested in maximising the far-field and directivity of the antennas, up to a point the S parameters, return loss and bandwidth/frequency behaviours are less important and we can concentrate on bulk characteristics like the received signal strength at a remote location. It's possible to use harmonic mixers, but my simple home lab equipment only covers up to 50 GHz and that's a simple spectrum analyser.
Luckily, the radar chips have all of the SHF components including the antennas integrated into the package, so we are not dealing with anything more than about 2 GHz outside of the chip and in fact we run an IF of 144 MHz for convenience. Some of the instruments out there are certainly about the same cost as a house. I'm just working on an EM solver model of a tiny choked feedhorn, 3.8 mm diameter with a 1.8 mm core and a choke ring 0.5 mm wide. Machining those is certainly fun. For certain very carefully defined values of "fun", obviously
Very enjoyable machining content 👌 thanks
I have no idea how I found this video and why I would ever need any of it but loved every minute of it. Subscribed.
Just found your channel and now binge-watching your videos! When I was doing my master's in physics I had the university machine shop make me several microwave cavities with intricate internal geometry out of OFHC copper... Just realizing now how painstaking it must have been for the poor machinists. Hope they didn't curse me too much!
Oh, but just think of the fun they had making up new curse-words especially for you! I'm having a self-inflicted nightmare making the smallest antennas I've ever attempted. Designed to give -11dB edge taper on an f/d 0.4 prime focus parabola, 3.6 mm outside diameter with a tapered waveguide from 2.00 to 1.80 mm in Tellurium copper and a face choke groove 0.5 x 0.6 mm with 0.2 mm walls. Definitely at the "interesting" end of what I can make on this 1 ton slab of old cast iron and 1950s tech. Still, I'm 1950s tech so it seems fair enough.
Your style reminds me of This Old Tony. Which means I immediately liked and subscribed after watching the video to the end!
Tony is ten levels of awesome above us mere mortals. I'm beginning to grasp the immense amount of work he must put in to each shot. The lighting is always perfect, timing impeccable and effects to die for. My hope is to get 1% better in each video, but that's logarithmic, so it will take me most of the rest of the century to get any good.
@@MachiningandMicrowaves I'm looking forward to seeing you inch closer to his production quality 😁

I have the heart of a machinist, the soul of a woodworker and a pile of attempted projects that shows that I sometimes have the hands and brain of a monkey with tools. Anyway, you had me at “all the words in your channel description”. The moment a bunch of cut edits of constructed waveguides turned into a stop-motion waveguide parade was enough to earn my respect and subscription. The production value and humor are icing on the cake. A nod and a wave (guide) from Texas.

Well the video lives up to the name of the channel, no doubts about that.
I think most of the vids will have a bit of each, but some are more machining for things that can be used to make other things that are used to make microwave things. Some of the other vids will be about microwave propagation and physics and antennas and waveguides but almost always using parts that have been machined. So I thought the channel name was a reasonable description. I could have called it "Neil has an unfeasibly huge amount of fun messing about doing his hobbies", but that might involve my OTHER hobbies. Like being a willow basketmaker or carpenter of green-oak framed buildings, or dressmaking, or wild gardening or... well you get the idea. Hmmmm, a basketmaking channel might go down very well with the ASMR folk.
Nice machining. I don't know much about signals but I do enjoy watching machining.
Seen the post on hackaday, wasn't expecting the antennas to have this shape, reminds me of a school project when some dude tried to make rocket engines out of 6061-T6, of course they all blew up but he spent whole lunches in the machine room, nice effort.
They do have a passing resemblance to a hybrid high-test-peroxide engine if you screw up your eyes and turn your head to one side in a darkened room.
Interestingly, there was a rocket engine made entirely of aluminum - but the only way to keep it solid is to cool it from the outside.
@@robbiejames1540 Bit lighter than Inconel I guess. I've never played with rockets, but one of the RUclipsr rocketeers is trying to use servo controller vectored thrust to do a Spacex-style soft vertical landing and I had thoughts of using three solid rocket engines which can be moved outwards under servo control in lieu of a throttle to reduce the effective thrust and control direction.
Must Not Start Any New Projects.....

Funny thing - I'm currently trying to build a rocket engine, but after watching your video I was practically chanting "no new projects" to stop me from immediately heading off and trying to make radars :) Thanks for the very interesting video.
LOVE your assistant!
I think I'd describe our relationship as "It's Complicated".
I remember when Dad did something like this in the 50's. He had a 500mm (there abouts - silly millimeter or two) a vacuum tube (valve ?) amp and all. He was snagged by the local law and went before the judge. He showed his Advanced Radar with an unlimited note on it - but the judge didn't recognize the FCC and Automobiles. Dad took it off but completed his tube (there I go again) timing system for our car. He was something else if you put him in an EE or ME shop. I have his lathe now.
Incredible content, wish I had found this channel sooner!
I'm a rank beginner at all this Choob nonsense, but I'm having fun despite having No Idea What I'm Doing. Thanks for putting up with me!
Brilliant! 😛 a good mix of machining and humour.
I was thinking of chuck offset just before your comments on spininng the bit as it's tightened. Lovely.
Drilling the 1.8 mm diameter holes 48 mm deep with long-series drills really shows up any offset or concentricity errors in the tailstock or chuck, or bends in the drills. I start the holes with a 1.6 mm centre drill and use a smaller high-precision chuck, and check the tailstock position regularly, plus I always clean the bore of the Morse Taper in the tailstock with a sheepskin-covered bore wiper and clean the taper of the chuck carefully.
Clicked for that interesting title, stayed for the great humor!

I'll then give it an etch and zincate coating, gold electroplate, then nickel, then a thick layer of copper electroformed and finally boil it up in sodium hydroxide to dissolve the aluminium, leaving me with a gold-coated corrugated horn with extremely low sidelobes, and great axial symmetry, but also, breathtaking bling and wizardry to impress my mother. Who watches this channel. Hi mum!
Very entertaining and informative! Thanks
Thanks for watching. Next step in that project will be the subject of a video in 2-3 weeks time. Making a range of dual-mode feedhorns to fit into those adaptors. Absolutely tiny features, with 0.5 mm grooves and 1.8 mm tapered bores. Huge fun using an ancient 800 kg cast iron metal-basher to make antennas so small you can lose them in a trouser pocket, or blow them off the bench if you sneeze.

So it turns out This Old Tony is actually British and knows all about microwave engineering!
Tony's hands went to Drama School. So expressive. I am not worthy even to wave my hands vaguely in his general direction. Observant listeners may discern a pattern in which of my fingers has a sticking-plaster in each of my videos. There's probably a Hidden Code or something. Spike Milligan's Q series on TV could be the inspiration behind that. Or it might be entirely a random occurrence. PhDs will be written about the subtextual nuance of the pattern. Academic careers will flourish. It'll be another "Rosebud" for sure.

I hope I can keep everyone interested, I'm fascinated by all sorts of things.

The part weighs less than half an ounce
As a software engineer (sodding enginerd), yes, I understood your threading joke. I smiled. That is all.

Fascinating content, much respect and best of luck to you, sir! Instant subscribe and like 👍👍👍
There's a huge amount of content I'd like to get filmed and produced, just not enough hours in the day to do it. Tonight's problem is taking the "electronic leadscrew" approach that James made, but using a really muscly 750 watt AC servomotor with an absolute encoder to drive the cross-slide, plus a hack of my DRO so I can make parabolic, hyperbolic and elliptic surfaces mirrors to work with microwave and mmWave antennas. Trying to design the mounting so it's impossible to engage the transverse leadscrew while the servomotor is active. I've been out in the garden with a green laser, translation stage and precision rotary table, trying to get the rear focus of a hyperbolic subreflector to be coincident and coaxial with the focus of a large parabola. That is going to be hugely challenging to film, but I just have to do it now I've had a dry run. Neighbours must think I'm having some sort of techno rave, but spookily quiet. I've been to silent disco events, where there are two DJs playing different tracks and transmitting them on two channels which can be received on selectable-channel headphones that all the attendees are issued with. Except I was listening to the level of a transmitted tone and trying to peak up the focus of the dish so the laser beams were parallel at 30 metres away. Honestly, the things I do for my hobbies!
Interesting and informative
The raw cut of the current video consists mostly of me swearing and invoking the Gods of Machining, and summoning various Daemons form the Pit. While that might be mildly entertaining, if I were to bleep out the expletives, the audio would just end up as a long string of Morse Code. Woah! if I said the right sequence of curse-words and bleeped them all, I could SPELL OUT something rude with the bleeps in Morse. Oh dear, that appeals far too much!
Thoroughly entertaining!

Don't you find rotating your drill as you lock it up helps avoid clamping on "pickup burs" on the shank from when you last let it slip in the chuck ?
That's a good point. I try to remember to clean up any drill shanks that get messed up, but most of the holes I drill on the lathe are done with drills I keep specially for that purpose, for tap sizes or reamer pilots, or are non-critical. I guess I picked that habit up from watching my father rotating drills as he chucked them but never questioned what the real reason was. A 50-year mystery solved! Cheers!

Heh heh, now if only I could use a file and do layout like Chris does, and be any good at silver soldering or machining or blueing or spilling the blood of my apprentice for layout fluid. In my dreams.... Not the spilling of blood bit, obvs.
Great video. Something more is needed. Can anyone say "turret lathe?"
Yikes, my father started work at Ruston and Hornsby in the 50s as a turret lathe operator. It says that on my birth certificate!
@@MachiningandMicrowaves great memories!
The fact that this is a hobby and not something you'd expect to be snapped up by the MOD is remarkable.
One of my project is making even smaller antennas with a hollow tapered horn that has fine ridges inside. Almost impossible to machine those, so I make an aluminium negative of the space inside, with sort of radial fins 1mm wide with a 1mm gap and about 3mm deep, then treat that with a zincate bath, removing the aluminium oxide and replacing it with a fine zinc coat, then without allowing the air to get at it, I rinse it and put it into a gold-plating bath, plate a few microns of gold, then nickel, then a very thick layer of copper. Once the copper is several mm thick, I machine up the outside of the plated area, drill out most of the aluminium, then dissolve the rest in a hot caustic solution. I'm left with an internally-corrugated tiny feedhorn which is gold-plated inside and electroformed copper outside. If I ever get the process fully debugged, that should make an interesting video.

@@MachiningandMicrowaves that’s honestly super impressive; mmWave technology these days is honestly blowing me away,
Glad I stumbled upon your channel. Antennae, waveguides, and high-frequency RF are black magic to me. I like your informal approach to the subject without dropping a load of calculus on us straight away. Careful about that AI though -- she might be your overlord one day. 👍️
I'll keep the vector calculus and Messrs Hilbert, Fourier, Fresnel and others firmly locked away for a rainy day. I might start going on about how waveguide wavelengths get squished out lengthwise as the waveguide gets narrower, and how mad things like slot radiators work, but I might slip in some maths and physics by stealth where it adds interest
*antennas. Antennae are on bugs
Excellent channel. Glad RUclips suggested again as I'm so down another rabbit hole in regards to... whatever they said... oh no collections or reporting... OK, sewing machines... albeit I can't help having thoughts of stitching fractal antennas for fox hunting with that more WW2 era look... thinking the WW1 era look was way more. For some reason I have thoughts of wearing hat sized whisper dishes in regatds to WW1. Thanks for sharing! Cheers!
Now THERE's a thought. I wonder if my sewing machine could be used to embroider wearable antenna elements or perhaps to sew them on to the surface of an inflatable bag? I can imagine Aimee would probably tell me off for getting sidetracked by yet another madcap scheme. Oh dear.

I'm trying to work out what noise the tiny ring of material left after parting off makes when it lands in the chip tray. I imagine something like a huge bell being dropped down a mine shaft. Hmmm, wonder if there are any royalty-free sound clips of that effect...
Hysterical... got a sub my friend
Subscribed. RUclips finally recommended a micro machinist! Def an interest of mine as I'm building a ride-on steam locomotive.
Lots of folks seem to be working on steam projects, I enjoy @MrCrispin96 Andrew Whale, @keithappleton @trainman4602 and everyone making Stuart engines, plus Lisa Milne (TiklishHoneyBee on Twitter). I'm more interested in clockmaking and watchmaking and radio stuff, and I've always fancied getting a stationary engine. My father worked at Ruston and Hornsby, and I'd like to get one of the 1930s models. I'm probably not ready to embark on building a steam loco - maybe if I ever get to retire!
@@MachiningandMicrowaves I am familiar with most of them but you have really got my attention.
I'm a digital electronics guy, radio has always puzzled me. My father is a ham and was an electrical engineer at Motorola responsible for the cellular base station division. Unfortunately that radio engineering knowledge never trickled down to me.
Greetings from Chicago btw.
@@GeeWillikersMan The really interesting detail is where you push beyond what you can design using Maxwell's equations and field theory by hand or rule of thumb and move into metamaterials and graded index lensing and unusual cavity resonances. I'm working on some models for axially-displaced ellipse antennas, which don't suffer from aperture blocking. That means using big AC servomotors with absolute encoders to drive the leadscrew and cross-slide on the lathe. I'm doing a lot of work on the mechanics and control systems for steering large moonbounce dishes to track the moon. Also messing with some non-radio electronics, but mostly PIC devices and linear microwave things like Gallium Nitride HEMT amplifiers. I do a bit of work with FPGAs using Verilog, but there just aren't enough hours in the day. I just noticed it's 1am here and I have to be at my desk in 7 hours....
This was great... cept I have barely any understanding of what you did.
That makes two of us! I have literally no idea what I'm doing most of the time. Doesn't seem to matter much though
I like Aimmee!
It's not under the radio noise. It's only under the noise when you consider it to be a 2800 Hz bandwidth, which of course it is not.
Yep, I'm guilty of a little terminological inexactitude there, well spotted.
I've just discovered your channel. Looking great :)
I'm having a lot of fun, I've been converting the Spidermandrel to have optionally four jaws each end as well as three. Almost finished the machining and filming, but it's almost 1 AM and the village is VERY quiet, so my machining noise is probably going to annoy the neighbours. Time to stop for the night I think. It's interesting that I only use around 10-15% of the footage, and it takes me up to eight hours to make a 30 minute video at the moment. I hope I'm going to get faster and more efficient. I'm a total beginner at this nonsense.

Subscribed! Ha ha. Great vids and amusing narrations. Just my kind of satire 😛
Very enjoyable keep up the good work 👍
There's just so much interesting stuff to talk about in microwave/mmwave radio experimentation, I've already got a year's worth of ideas mapped out. Another upcoming project is building an az/el hydraulic moon-tracking system for my big 3 metre diameter General Dynamics solid parabolic dish so I can do moonbounce on 10 GHz. Lots of intricate control system engineering and I want to to remain usable in significant wind speeds. I've bought some Gallium Nitride devices that can run over 90 watts at 5.7 GHz, a pair of those would make a nice loud signal off the moon on 6cm. I'm working on a set of Pickett-Potter dual-mode feedhorns for 122 GHz with various different gains for one of the French experimenters who's trying to optimise the illumination/overspill of an offset parabolic dish. Lots of challenging stuff to do. I need to retire from the day job, or just stop sleeping!

Awesome, thank you!

I keep trying to get clean snaps when I karate-chop bits of 25 mm stainless bar, but all I get is bruises. As for that stuff he applies with an eye dropper along a scribed line on a bit of mild steel, I waited AGES and all that happened was rust. HOWEVER, my experiments with modified free energy machines and laser-pumped plasma gyrators for ablative machining are showing great promise. Assuming, of course, that I don't set fire to the shop. Again.

I was a little concerned that I might get angry complaints about the lack of quick lunch recipes, no-stir cake-mix comparisons and of course, unboxing vids featuring the latest Samsung Hotblast or Panasonic Slimline models, but so far, the only manifestation of that is in the number of dislikes! If I could just approach Tony's level of skill in lighting, I'd be very cheerful. His level of performance and timing and special effects are the stuff of legends. When I try to replicate his telekinetic atomic cleavage operations, I just get abrasions and bruising and sadness,

That Wilhelm cat noise is the last real joy I have in this sick, sad world.

This feels like it's got some This Old Tony, some Internet Historian (mostly the snarky TTS "assistant") and maybe some Styropyro?
I can't quite put my finger on it but I DEFINITELY like it and am excited for future things to come!
Also, if the parts didn't come out as desired, just blame it on forgetting to spinn the endmills while inserting them in the chuck.
Also, why not solder the cavity to the board and using press-fit alignment pins? Too large of a risk of damaging the chip?
The boards were made at a PCB fab somewhere in China and shipped out by Tim Tuck from Australia, and they are designed to work with some aluminium horns that Tim had made. If I was starting at the PCB design stage, I would have to consider a fixture that could perhaps be glued to the chip surface. At these frequencies, 1.2 mm of metal looks like an insulator as it's a resonant halfwave, also the capacitance of the body to the PCB is several picoFarads, which at 122 GHz is perhaps half an ohm, so an electrical connection isn't really needed. To get the ultimate in performance, I think we'll need to use a pair of the chips, each with a carefully-optimised coupler, perhaps using a machined Rexolite 1422 cross-linked polystyrene dielectric lens to get the maximum possible performance out of the chip. There is another chip with two four-element patch aerials on the chip package, and that might be worth a try, I have a few of the chips, but I am thinking in terms of an XY translation stage with flexures to position the receive or transmit antenna at the sweet spot, as we don't need concurrent receive and transmit for our long-distance communication experiments.
10:20 people in the 60s shamelessly fab with no lobe.
I poked the button, but you still need to explain why Polish carbide and confirm that you managed your thread handling correctly!!!!
I tried adding threads to the machine, but the needle kept jamming in the fabric when I tried to do buttonhole stitch.
I'd love to see what you could come up with for a fish finder. How sensitive you could get the radar part that detects the fish and how clear you could get the signal to show up on the graph. That may be something you can patten qnd get a nice payday with. Fisherman are always looking for better technology and getting the best advantage possible.
The difficulty is that radio waves don't travel far in water, maximum range depends on temperature and salinity, but is only going to be a a centimetre or so, which is why sonar is used rather than radar. Getting a high-resolution image from individual fish needs a wavelength of about 10 mm, and that means a frequency of something like 200 kHz from a piezo sender. Those usually reach 10 metres in clear water. If it was possible to have a large phased array of those, you could get a good 3D image, but fish are an awkward shape and contain a lot of water. Definitely an interesting challenge. Now finding fish IN THE AIR is a different matter! Getting fish airborne might be somewhat more challenging. Although.... ruclips.net/video/tLmJjRqXDCo/видео.html
@@MachiningandMicrowaves @Gregred78 Maybe a marine radar (or array of for imaging) to better resolve how those in the proximity or target locations are doing in regards to catching fish? OK, maybe not and far more expensive... though worth a try? :-|)

You're going about it all WRONG sir...
If the problem is that the radar doesn't penetrate far enough into the water, then surely the OBVIOUS solution is to simply get rid of all the water!

I've always done the same thing Turning the bits or stock In the chucks lol
I was just copying what I saw my father do, but didn't realise it was more to do with avoiding offset errors caused by using drills with burrs from being allowed to spin in the chuck
The computer/machining joke about munging up "threads" is equally applicable to "files" no?
Also I've seen a lot of machinists use shim stock as consumables rather than cheap gauge blocks. That said it would be one more thing to drop into the chip tray, and shimstock it a bit sharper than a carrot.
It not truly FAB with out lube . I still build valve amps Unironically .
very well done!
wish I'd understand anything about mm wave witchcraft
Heh heh, it's like real radio, but the parts are small enough to lose on your desk. Maxwell's equations still apply, the same as at VLF. Lenses become practical, but machining tolerances start to get very tight. These parts are quite large at 122 GHz with a wavelength of 2.44 mm. At 241 GHz, a waveguide tube is only 1 mm diameter and the surface roughness needs to be at the micrometre level. I use a video microscope to machine many of the parts, and a binocular microscope for assembly. Many of the tools and techniques are similar to those used by watchmakers. I have a licence variation that allows experimentation between 275 GHz and 1 THz. Now THAT is small stuff.
We are always a disappointment to our fathers, be it for not achieving enough or over achieving! Great video thanks and subbed
This is a great informative video. I am an electronics engineer with a fascination for machining and microwave radar stuff - just a fascination though, apart from measuring wave length with a sensor in a split wave guide at school and using them to excite water atoms I never used microwaves.
Well... I did try one of those as cheap ass coffee radar sensors but liked them as much as cold coffee 😕
This is going to be a slow and steady reveal, I'm ideas-rich but time-poor. Storyboard number 58 just got added to the list of videos I want to make. That won't see the light of day this year I guess. Unless I retire from The Day Job. Must buy a lottery ticket!
Pro Tip: ALWAYS use a bit of lube with a reamer 😆
Have you considered a UV filter for the camera that you can shove in the dishwasher once it’s drenched in oil?
Wouldn't it be great if this stupid camera had a filter ring or a viable way to hold a filter ring with a rubber boot or something? Talk about Buyer's Regret. It isn't the worst camera I ever owned, I've had a LOT of cameras, but it's the second-worst for sure. I have a mount that can take a 58 mm skylight or UV or whatever, but that then needs some sort of shroud to fix over the camera body to stop it seeing reflections. I guess these things must be useful for something, but it's just about unusable. The dial pad thing for focus is dreadful. If I hadn't spent so much on the horrible thing, I'd throw it away. If I can find a way to trade it for something that works, I'll definitely be doing that. Good points, the audio is fair, but the lack of a power input is unforgiveable, the focus is almost entirely useless except for selfies or vloggers. I have no idea what I was thinking when I bought it! Horrible. Sony ZV-1 #NotSponsored as Quinn would say.
Dude,.. I'm a RF engineer who loves machining and spends like 3h a day on RUclips for educational videos. How did it take so long to find this awesome content! Sub+1 :)
"Educational" might be a bit of a stretch goal. perhaps I could describe the taste of cast-iron dust that somehow got past my full-face visor and breathing mask and is crunching between my teeth. I'm sure some of it is in one of my socks. I must see if my fingernails now work like an iron-dust inductor core. Oooh, I could make a WILD Theremin or Ondes Martinot with capacitance AND inductance detection from my fingers as inputs. I did make a very silly musical thing that used doppler reflections at 47 GHz, but unlike a Theremin, which works on position and capacitance, this worked on velocity, so to keep a constant tone, your hand or table-tennis racquet had to stay at a steady speed. Rather brain-scrambling at first, and you can only do shortish notes, but it's a bit like playing a piano accordion or squeeze-box.
Current status: Putting a rare-earth magnet in my boot and shaking it around to get the cast-iron bits out. Next step: put the sock and magnet in a poly bag and shake it like a Polaroid picture until the sock becomes useable once more. If it ever does.
@@MachiningandMicrowaves well. I can see that you're having some great ideas coming up here! Really looking forward to get this instrument to a proper use :D
Go on with that stuff! Really appreciate and enjoy it.
I had a laugh as "Amy" for me is the name I use for Amitryptoline. A pill that stops me going loopy, and puts me to sleep, so happy days.
Why are you using Polish carbide? Ain't American carbide good enough? (or is it just not pretty enough?)
Very good! (actually it's Korean, but has a very nice Polish)
Two magnetrons with each being out of phase 180 degrease with each other can transmit at vector of intersection waves . scalar ? tested with homade klystrons. im using a spent high pressure sodium arc tube for the electron emitter and using voltage multiplier with bismuth anode cathode style rings 16x .
Destructive interference isn't quite the scalar wave Tesla reported. Please look into phase conjugation/4-wave mixing in non-linear media, which normal antenna interference effects do not allow. Normally two sources of waves that are 180 degree out of phase will destructively interfere between sources, but there will also be constructive interference INSIDE the sources which results in HEAT. The "destructive" zone between antenna doesn't really destroy energy, it just moved it into the "constructive interference zone" at the boundary(the antenna). Same thing happens in noise cancelling headphones, sound waves are "destroyed" but the pressure at the speakers is now higher and so the speaker experiences hotter, high pressure air and the speaker magnet circuit experiences greater resistance to motion, and therefore higher heat losses.
Now things get a little bit different with phase conjugation. "Time reversed" waves occur in non-linear media. These waves are almost perfectly equal and opposite to the phase, momentum vector, polarization and amplitude of incoming light because of the process of 4-wave mixing inside a holographic diffraction grating formed by the non-linear medium. This means instead of HEAT occuring in the material due to constructive interference of waves, a holographic image of the environment will be stored in the polarization of the electrons in the material. You could call this type of wave between objects "scalar" in a sense because it requires the vector components of the wave field between sources to be equal to zero. Quantum potentials such as the magnetic vector potential and the electric scalar potential however are NOT zero in between these types of sources and we can detect effects like the Aharonov-Bohm effect where magnetic B field and electric E field =0. Quantum potential effects occur even in the absence of Electric and Magnetic "force fields". Tesla may very well have discovered this effect with his pulsed DC experiments, which formed a sharp pulse of electrons and ions in the air, such a plasma double-layer accelerated has highly non-linear electro-optical susceptibility. Tesla later invented a non-linear shuttle oscillator circuit that modern microwave engineers are beginning to understand would explain a great deal of the unusually high performance reports of his "Magnifying Transmitters". It wasn't just destructive interference optimization, it was TWO PAIRS of photons, which are locked into a pair of phase conjugate mirrors. If the circuit acts as a non-linear signal mixer, it would be capable of phase conjugation of radiation, by dynamically altering the impedance of the circuit, and storing the wave energy in a matrix of capacitors which behave like a holographic image of the incoming waves, so that outgoing waves are phase conjugated and energy remains bottled up between two transmitters with almost zero losses to heat or scattering. This is why Tesla thought he had gotten longitudinal waves, which isn't exactly incorrect, it's just that quantum scalar potentials weren't considered "real" by scientists in Tesla's time until quantum mechanics showed the "A-field" has real physical effects on matter where no EM waves are "exposed".
What I find most exciting about phase conjugation besides wireless power transmission, is how it could boost technology like "optical tweezers" and laser cooling. Basically the Sci-Fi kind of "force fields" become possible. The dynamic holographic effect that phase conjugation achieves allows mirrors to automatically resonate with a source of waves with almost no losses. Resonant cavity mirrors can store wave energy based on the Quality Factor of the mirror, High Q factor=high Gain. If a resonator can automatically lock on to objects then you don't need lenses or phase shifters. If your phase conjugate mirror can lock on to a bit of matter, and you deliberately pulse the signal like Tesla did, or you modulate the frequency, the off-resonance waves will not match the hidden "scalar" field which the hologram stores, so it will push or pull the object, depending on if it was Red-Shift or Blue-Shift. The hologram will lose energy proportional to the force on the object and the new hologram will attempt to lock on to the object again in the new position. Objects made of neutral matter, that are phase locked with the hidden "scalar wave", just as Tesla described, will experience a penetrating, uniform force, without much heating or scattering light. Already this technology is being explored by medical science to penetrate human body with low energy waves, which are conjugated by a phase conjugate mirror behind the patient, so that the time reversed waves return through the tissue backwards, to give a projection like an X-ray.
That sounds like quite some level of excitement. Nothing better than experimenting with potentially-lethal voltage and RF fields. Splendid! I think I'll stick to Gallium Nitride HEMTs though!
@@MachiningandMicrowaves Thank you for your video and your dedication to your work. Dualing Klystrons does sound rather dangerous and I'm afraid if he's after exotic interference effects he's going to have a lot of trouble, though he could make some fun toys, like a Wakefield accelerator if he aimed the output of both Klystrons at the correct angle through a gas cell.
Semiconductors like Gall-Nitride, Gall-Arsenide and Barium Titanate are suitable for making switching devices above microwave frequencies, but did you know they're also capable of being externally pumped by radiation to form a phase conjugate mirror? The US government research into such materials for RADAR stealth aircraft led to an interesting discovery. Microwave resonances in certain ceramic materials leads to strong coupling, whereas off-resonant signals produce attractive and repulsive forces. A cube of Barium Titanate can be levitated above a Magnetron tuned below the resonance, the Redshifted waves mismatch the optoelectronic resonance frequency and induce a repulsive electromotive force. Phase conjugation can also be used to time-reverse signals, which can cloak an object by retro-directive destructive wave interference, which can also be used to obtain the location of the source of incoming, interrogating RADAR signals without giving away your own position. Research into RADAR absorbing materials and non-linear opto-electonics for stealth technology is therefore highly classified due to the weapons guidance and counter-RADAR potential. Furthermore field-effect propulsion technology would be incredibly disruptive to the global balance of power, but I believe that it is important to share that information across multidisciplinary fields in the scientific community because of the tremendous benefits to society it could bring, such as nearly lossless beyond-line-of-sight wireless power and data transmission.
I see you opted to avoid the NSFW definition of "munge". Thank you.
Heh heh, always walking a fine line. My mother watches this channel!
Lovely video 😊❤
Would some flat clear perspex/acrylic help protect your camera?
The problem of using anything other than a perfect optical filter is that it causes blurring and flare and loss of contrast, plus if any light gets behind the sheet, it causes reflections. Other tha flinging this horrible camera out of a high window, it should be simple enough to machine a Delrin collar to fit over the lens body, then cut a filter thread for a 52 mm Skylight 1A or similar screw-in lens filter, perhaps in a brass ring that is fixed to the Delrin collar. Oh squeee! I think you've just given me a subject for another video. Cooler than a cool thing! Thanks v much.
On the other hand, how Steampunk would it be it it was all in brass with an O ring seal and stainless steel knurled clamps. I like this idea more every minute
Wow! I've seen some niche videos, but this...
Much deeper niches on the way! Also shallower ones.
I'm not sure what everyone is doing with these things but from my field, is there anything useful on a Rosemount radar level detector, for instance? Foxboro makes better and cheaper ones. When a plant get's upgraded, these kinds of things end up in a dumpster even though they are perfectly functional. Sorry, we use them for tank level in plants. Normally they are used in products that are caustic or foamy or splashy. There's also sonic ones but that's not what we're here about. The radars seem very powerful and they come with a horn that...I really don't know what it does but it has a one. Anyway just something that attracted me here.
The thing that makes these chips particularly interesting is the frequency they use, which is in a region of the mmWave spectrum where it's REALLY hard to find anything that can generate a signal at all, so when SiliconRadar brought out two different chips for the 122 GHz band, which is a part of the spectrum that amateur radio experimenters are licensed to transmit on without the limitations of type approval, folks got very interested. There are some vehicle radars in the 80 GHz range and others around 24 GHz. 80GHz is not in a very useful part of the spectrum, and there are lots of much better solutions at 24 GHz. SiliconRadar are also working on 134 GHz chips, which I guess are used for non-contact sensing. Those are of great interest as that band is much further from the oxygen absorption line around 119 GHz that limits the potential range that can be achieved. We are pushing these things way past their design parameters and having to find innovative ways to get around the limits. In the early 1970s, we did the same with the radar speed trap devices (Gunnplexers) at 10 GHz, and before that in the 60s with Reflex Klystron vacuum tubes, so this repurposing of tech has a long history. I love it because it's huge fun, I get to design stuff and make it and ship it off to friends all over the world so they can enjoy experimenting and pushing the limits of the Laws of Physics a bit.
So in general, there are some ex-equipment units that are really useful, like the Wavelab 23 GHz units that can be used on 24 GHz, but if there is anything useful in a detector there's probably someone somewhere who's found how they work and made a video or a blog post about it. I've not seen any mention of Rosemount or Foxboro units (so far!).
Why don't you just make a Ka band multi-phased array high powered RADAR unit, and power the waveguide tube at +20K volts?
That would certainly be a whole other level of fun!
