There's a frequent 60Hz buzzing sound from my lapel mic picking up interference. I didn't notice it until after the video was uploaded and this isn't the most significant video ever so I'm not going to worry about it too much. This is why I don't really like using the lapel mic.
Yes, it would have been possible to fix it if I had noticed before uploading. But a 46m 4k60fps video takes a long time to fix and re-upload and the problem isn't that bad. I could be look at up to 8hrs of re-rendering and upload to fix it.
Its mildly amusing when you touch your desk because of this
I can't even tell so no worries 🤣
Hey I recently had an uncle who was an audiophile of sorts pass away & he had a studio with all kinds of recording eqt from the late 70s- mid 90s mostly. But there is a JL Cooper Electronics Sync Link for Interface Synchronizer for Macintosh among all the stuff. Would you have a use for it? From what I can tell they sell for 20-30$ but if you want I could send you more info or pictures in an email.
Makes sense that it only appears when you touch the desk, because that is grounded and thus we have the difference in ground to create the humming voltage :) I have a pro audio desk and setup here and even I get ground hum when I am not careful or plug in equipment without thinking. So.. it happens, no reason to reencode and reupload.
Seems to be buzzing when you touch the anti static mat
21:16 The most interesting part of the tour, thank you Prof. Farnsworth!
"a tub of serial connectors"
Me, an intellectual: *A bowl of **_serial_*
"intellectual"
AkBkuku: Let's just ignore that for now
Everyone watching: **immediately gets interested in that thing**
lol @ the 60Hz hum (ground loop) every time you touch the ESD mat
Also the static bursts when he touches the 16500C's screen.
I believe the reason for the IR connection on the Fluke for logging is something to do with isolation
27:30 - if you want to use your 858D for some longer time, never switch it off when is heated. When you put the heat-gun in the holder, it will turn off the heater, but leave the fan running until the temperature falls below 100°C. It doesn't draw a lot of current, but the heater is mains powered, and the triac regulator introduces a lot of current ripple.
Good tip. I just got one today by coincidence and noticed that tip in the broken English manual. But, of course, I didn't read the manual before I had already turned it on once and did exactly what he did in the video. :)
flashbacks to "don't touch the thermostat" dads thinking tiny fans take like 200W somehow (and any arguments that you'd feel the heat from that are met with a "i know how much power a fan uses" non response)
I've got one myself. It's not a bad station for a hobbyist, but I did have to replace the cord with something that's longer and easier to use.
Congrats on the progress toward your dream workbench setup. Your enthusiasm is contagious!
They don't make desks like they used to. My main workbench is a engineer's desk that came from Intel, circa mid to late 70s. I've had it for nearly 20 years now, and while the desk weighs a ton and it's a huge pain to move around, I'm *never* getting rid of it. I'm convinced it would survive a nuclear blast.
@wargent99 Isn't living in a throwaway society fun?
my desk is made out of a honey comb of mdf from ikea. i don't really see the huge deal about having a desk that can withstand a nuclear blast and is a pain to move around.
Yeah, I've got an old metal desk that I got from my dad which probably dates back to the 60's or early 70's, and I've no intention of getting rid of it either. Old desks and benches were made solid!
That's an awesome bench. I used to work at an electronics manufacturer soldering wires and various components onto PCB's. For ESD protection we had a heel strap on each foot. And wore a smock that was esd rated and had a cord connected to it that you plugged into your work station. Although I think the engineering department did have one of those ESD mats on their bench.
My suggestion is you just enjoy the heck out of it! Its a great feeling putting together a good workspace you know is going to make working easier. Especially if you've spent a lot of time just making do with something inferior. I've been there most of my life haha.
The ESD mat will help with working on old gear with early ICs that don't have built-in ESD protection on their inputs.
If the chassis is plastic, just dragging it across a laminated work surface could build up a relatively low static charge of just a couple hundred volts. And you could easily build up enough charge carrying the device over to the workbench, which could be transferred to the work surface when you put it down. Unless you dissipate the charge before working on the circuits inside, it would be easy to kill those old ICs without ESD protection. If you've got a work surface that doesn't generate static, but instead dissipates it, then that's not an issue.
And yes, an ESD strap may not help.
While you've handled and dissipated the charge from the chassis via the ESD strap, the work surface may still be charged. Then when you place the successfully extracted circuit onto the work surface, the charge from the surface finds a path through the circuit to your grounded body.
In theory the 1M resistor on your grounding strap should slow the discharge and stop the voltage spike that kills the parts. However if that charge finds another path through the circuit, say the tip of your grounded soldering iron, that could kill the old ICs on the board.
Hopefully that explanation makes sense. I'm sure someone smarter than me could've explained it more succinctly.
46 minute Tech Tangents video?? Awesome.
New subscriber here and i realize this is 2 years old but im binge watching all your videos and slowly catching up. Winner winner chicken dinner buddy you got me hooked haha Good job.
As for anti-static mats, most things with FET inputs have ESD-protection diodes built in so you can often get away without either a mat or a band, but if you're working with irreplaceable (or not easily/cheaply replaceable) equipment (like old computers, in your case) I think it's worth it, if only for the peace of mind. Personally, I don't even own a mat and only use my grounded (through a 1MΩ resistor) band if I'm working with discrete FETs, but I'm sure that will change if I ever fry something with ESD. I remember reading in The Art of Electronics about the authors having trouble with a particular FET model getting destroyed even with ample ESD precautions so they ended up just using a different model.
My room is in the basement, with a concrete floor and no mats or carpets. Static really isn't much of an issue in my environment. I've got a mat and strap anyways, but I mainly use them if I have to travel somewhere.
This video made me happy after seeing your excitement over your new workbench. Great video you gave a lot of good ideas on buying things and how to set up a workbench.
"Assorted lengths of wire." 🤣
That's the first Futurama reference I've ever caught in any of the retrotech channels I watch.
So nonchalantly put. Loved it.
Oh, man. This reminds me of my old setup in grad school: Agilent/HP E3631A power supply, 34410A DMM, and 33220A function generator. I had a Tek four channel scope that I can't remember the model of, but in our main lab we had a similar logic analysis system setup to the one you have here. All of my four essentials were on a network switch via LXI, and were controllable via the lab bench computer. I'd love to get back to that kind of setup for the work I do now, but I no longer have that kind of budget.
It already looks like it's been there for 30+ years too!
Very cool. Great to see you excited about the ability to take on new projects with the new setup. Still crossing my fingers I'll have the space soon to have a permanent workbench setup.
Btw ESD is taught pretty heavily at my work. There are courses on how to handle static sensitive devices, how ESD mats work, how self-grounding works, and so on. It's also something I learned about in school. Pretty useful info that most folks seem to not understand.
Waynes World! Waynes World! Party Time! Excellent!
Karl Burnett -- Same.
I can see your self also becoming a common placement for a overhead camera mount (top-down) like, it's very common and you'd be able to get some amazing circuit shots for your personal work :D
The Fluke data output is optical because the meter input is rated to 1000V, but also designed for physical compactness. If you only keep one half of the opto-isolator inside your chassis, it's much easier to demonstrate that there's no failure mode that would bridge that high input voltage onto an electrical output terminal.
The RF power meter would be awesome for atx pc build. It looks proper industrial cool.
The only thing I'd suggest is a VESA mount arm for your monitor. Don't know how it would work for filming, but it's nice to pull the monitor closer for viewing datasheets, schematics, etc. while working.
I genuinely love this video. Awesome to see your new workbench!
Only people who loves his work can be happy to achieve a proper workplace. "Me too"😁
I'm watching a video about a man talking about his work bench. righteous
Reforming capacitors is fun! When it works, it can save some money.
"It's properly grounded" **BUZZZ**
In EE school I had some shop classes (operating things like lathes) and there was a strict rule about workbenches: When you put things down, your tools go on the right and your measuring equipment goes on the left (if you're right handed). First of all, that way you prevent accidentally dropping heavy tools on fragile equipment, and second of all it helps to not get things in your way. So I would have put that soldering iron on the right side of the bench, otherwise you will find yourself endlessly annoyed at dragging the cable over your workpiece and getting in your way. For the same reason, I might also have put the cabinet and drawer on the left side if possible but I see you have a wall on the right so I might have made an exception there too.
I would look into replacing the tube light with an LED tube or an LED strip, preferably with a dimmer for video recording. Yes, Tesla > Edison but a DC-based light source would really help control the lighting and it shouldn't be too hard to accomplish even if you have to DIY it (which probably shouldn't be necessary nowadays).
Other than that, it looks like a great workbench. I'm jealous! And I'm not sure but have a funny feeling you're excited about it ;-)
Congrats on the new workbench!
Love the ESD mat saga, what an amazing market eh.. You could coat the desk in kapton tape ;D
IRT the HP 16500, when you set up your profile of a device, use the 3-1/2 inch floppy to save your work. Or save it through your network on your laptop. I loved using this model on products at my last employer, Digital Equipment Co(DEC) back in the day. You will get frustrated figuring out all the quirks and tricks, but it is a great analyzer. I am so jealous!
Funny, my dad worked for a company that installed all the early data terminal machines at the gov. Liquor stores and safeway grocery stores in Vancouver BC. And he has the same solder sucker from all the way back in and still works.
Thanks for the Futurama reference!
The 858D is an absolutely excellent device - no need to upgrade that. I guess the current draw is an issue in a 120V land though. We have 230 volts here and it works perfectly. I've had three hot-air stations, and this is the best so far.
Sweet bench.
Looks like it came out of a high school or college science lab.
It’s great, isn’t it? Had these in my electronics shop in high school. Minus the ESD mats. Just had an oscope, power supply, and frequency generator thing, I forget it’s name. Good times, though.
Collage is art, not science.
@wargent99 Made in Japan is a mark of quality; that can't be said of Made in USA.
That's a really nice setup. For a less complicated portal DMM, try a Fluke 77 or 87. For Analog VOMs, I prefer a Simpson 260. I've wanting to assemble a decent workbench for years, but space, time, & money are limiting factors for me. Being a family man has a few tradeoffs, but that's a story for another time.
At any rate, nice job with your work bench!
Yeah, I've got my 16500(B) in a 19" server rack. That thing just takes up a LOT of space, and is too heavy to just scoot around.
As for the static mat, I found that having my room in the basement with a concrete floor, no carpet, and no plastic tables, static buildup isn't too much of an issue.
Maybe I'm too lazy to buy an actual brass wool holder, but I just grabbed a wad of steel wool from the kitchen :P
I've got a fume extractor that's pretty much identical. I mounted an LED strip on the underside so I could tilt it forward and still have good light over what I'm soldering.
Fluke uses the LED connection for isolation reasons. If you are working on a 1000 v circut and you are data logging, you really don't want any way for the test voltage to reach your computer. Just saying. It is nice to have a real space to work in, been there, done that.
Man, this is what I aspire to have, me being a computer engineer in the making. Took electronics in high school (tech school) and this looks like a dream.
Same here
... Partytime... excellent... 😊
Thanks for the video:)
To your concerns about "invalidating" ESD protection with the shown contraptions. Usually static electricity is build up by friction, e.g. you walking around. It happens very seldom(a joke!) that your protective mat or equipment walks around on the carpet on their own:P By grounding YOURSELF as the main culprit you also discharge possible charges and as a bonus it is mostly YOU handling and touching all tools and materials, very seldom (again, a joke!) the equipment touches MOSFET components on its own, because it is not alive. The ESD protective mat is very good not building up any charge with any other material. The isolated "hands" of the helping-hand are of no concern, the humidity of the air will discharge something like this and they also don't move from alone around the room (Maybe on Halloween if you are looking away? ... doesn't matter, you are the one kinetic force roaming around the workbench. Nothing else can build up static and you always function as a discharge ground with your body ... if you are correctly grounded [1] ). BTW metals are conductors and can take part in discharging ESD(like in your ESD protection equipment), but good look ripping electrons out of them by friction.
[1] Not seen any professional having a Wimshurst machine or a plasma-ball-light on their bench. Maybe plumbers, but not electronics technician.
P.S.: Correct protection of the workplace with the right fuses and residual current devices, or knowing how to handle isolating transformers, is also very important. Those who are dead don't have to worry about ESD anymore. The "grounding" will be great, then;)
Have fun making:)
Kill-a-watt is better than a multimeter because it measures consumption in watt hours. Thanks for the great video!
Remember your Windows 95 Gateway? Well, the first disc in the “Software Pack” is very special. You’d better have not gotten rid of it.
I worked for years in the electronics industry. We had to wear a wrist strap, heal straps and an ESD smock. They had to be tested everyday also. :)
It would honestly be really cool to see the light blue power meter working again! and even if its out of spec and not really useful i still find it really cool and im interested to see what they did with the nixie tubes and how they got them to work with it
dunno
keep it up! love your content
Return of the blue ESD mat!
That is a nice bench. It's really similar to the one I have to make for myself.
the main reason for the mats are to prevent a static build up as you work on things. especially crts and ESD sensetive devices. just remember to tie your soldering iron into the mat and thus into the grounding point your strap is going to. this is because you can get a static charge between the item you're working on and the tip of the soldering iron
Love the dot matrix supporter printout hehe
The ESD stuff is really only significantly relevant if you're in an environment that has/generates static in the first place. i.e. on carpet with person using it wearing a sweatshirt or something. If you're on a regular floor or plastic floormat and the tabletop isn't conductive (wood, melamine, stone, etc) and your're only moving around a normal amount in a smallish work area, it won't matter cuz you won't be building up much charge. Admittedly, vintage electronics ARE more susceptible to ESD than modern designs, so its not useless.. its just of dubious significance level.
Looks good, have fun with you're projects
Look at the HP 603xA series power supply. I use the HP 6033A, Agilent E3630A and a Agilent E3611A.
I'm very jealous of your carry case for your DE-5000 LCR meter. I bought one but didn't get the carry case for it, and I'm always forgetting where I put the accessories.
I've got a nice one from intel/digital equipment when I worked there. My wife uses it for a laundry table :(
I'm noticing a lack of arb. I'd suggest seeing if you can find an Analogic Polynomial Waveform Synthesizer (2020/2040/2045). It's basically a function generator but you mathematically define the function instead of selecting a preset or loading in a sample, though there are triangle, sine, square, and noise waveforms built in. They can be had on eBay for a few hundred if you're lucky, they're just overall a really cool device and I find the mathematical approach to waveform synthesis really neat and something I wish I saw more of.
Futurama reference. Nice.
a 46 minute video just going over an electronics bench and cool test gear? Time to get some snacks and get comfortable and satisfy my inner electronics geek
EDIT: 35:40 Ahhh man, you've gotta get that working and show us! I love me some nixie tubes :D
EDIT 2: You could use some of those moveable camera mount arms that clamp to stuff (like a vesa monitor mount with desk clamp but for cameras to position a camera in front of the equipment to be able to show the screens when you need without having to hold up a camera or stop what you're doing etc, just keep everything rolling and edit it all together afterwards?
Totally OT, but I noticed the flicker in your OBS capture (The panel at the top). If you want to stop that you can temporarily disable the compositor ( in KDE there is a default keyboard shortcut of Alt+Shift+F12 ) and it will stop the flickering.
That works, thanks! I put a note in my OBS scene to try to remember to do that because it is very annoying.
The HP Logic Analyzer thing needs some more videos. Your restoration of it was fantastic. Did you ever get the CF storage thing worked out? I have NO need for that machine but I want one, just because it is all Unix-y. Thank you for sharing your lab, really fantastic!
Love the dot matrix printer outro, but it does have a legibility drawback. I'm sure is fine in-person, but watching this on RUclips on a notebook computer... I can't read that at all, it's just not dark enough.
Yeah! Micronta Range Doubler VOM. My first meter, think it cost $20 in the late 70s.Still use it.
Would a LED strip with a diffuser work as a replacement for the light?
Yep, you definitely should mount that light above.
OMG I want that workbench
Yeah, I got the same problem with the hot air soldering station I have lol
Look at Anycubic for their Delta printers. I picked up their predator for 440usd and its HUGE. They have a half size one thats under 300$ and they're really REALLY good right out of the box especially for the cost.
Years of solder suckers made me snap last month and buy an offbrand Chinese one. It's awesome so far. It's something I never wanted to buy
Guess the ESD mat isn't grounded since it makes you hum :D
I was so happy when I got my work benches and they aren't even specialized for repairs. they just have a few power strips underneath.
Yes, the clock I had as a kid again!
As soon as you pulled out the hot air unit and flipped on the light I knew exactly what was going to happen because it happens to me every time I use my AUYOEHE or whatever branded hot air station. AEIOUY? AYAHUASCA? Doesn't matter because it was the best $40 I ever spent
My god, he looks like a board games nerd from the 90's who's going have a heart attack when Matrix and Lord of The Rings arrives in the cinema
I have one like this as well , but mine has motorized lift adjust and weight is an absolute ton
I'm glad i saw your face for d first time
Great video
even with a good filter the hot air will probably still make cheap led lights flicker. I have a tr1300 quick and it flickers even worse and on a dedicated circuit.
AkBKukU: tries to make a video
ESD mat: 🅱
Where's Garth?
Im amazed it took you that long to get a workbench but you have equipment that is quite costly, you could have built it or just assembled it from alu profiles
u can covert the anet a8 to boden.
thumbs up!, you'll be a new Mr Carlson soon! :))
This workbench is appealing, sexy, a real beauty.
4:08 Did you forget to slide on some heatshrink before you soldered them together or are you just not using any :D
Thought I'd mention it because I still bloody do that sometimes and it's still a little annoying haha
EVERYONE in the 80's had that same Memorex Power Center, didn't we
I really wonder what made your kde panel flash red while recording?
why does the static noise increase when you touch the esd mat?
I have never used a static mat. I never bother with any static strap. I have a wooden desk (kitchen work surface) and laminate wood effect floor. There is zero static. NADA. Anti static is pointless unless you're in an environment where static is being constantly generated (carpets covered in cats).
lol why your blue mat makes buzz sound everytime you touch it
Love it!
Does your top panel always flash like that when you move the mouse?
Congrats I'm slowly working on mine....
when ever you touch the hp touch screen it makes a static noise, i dont recall that noise when you fixed the HP machine, but could be wrong. Then it stopped making that noise after a bit
I have a hot air gun like that too. It draws a lot of power.
Crazy dude, what do you have?
What is the hair conditioner you use?...
Where is Garth?
Open it up and put a resistor in it. They're like 750 watt air guns haha
