The Analog Discovery can be configured as a network analyzer for audio frequencies - that gives you the bode plot (gain vs. frequency and also phase vs. frequency) automatically. It works quite well in my experience.

OH UM A WIZZARD NOW ! Please let there come a time in my life where i can demonstrate this sorcery and get undue respect.

I would love to ask you questions but it would literally be like a caveman talking to Einstein , Hawking etc

Now please a tutorial on everything one needs to know in order to create said finish.

Hey, if it ain't a spherical mirror at least it's aspherical mirror!

I cannot for the life of me find Precision Mechanics by Kittell. I have looked on amazon and ebay, so far it's the only one I have tried to find. I just recently uncovered your channel. You've shown me a topic that I didn't know existed, and it's the most compelling topic that I have come across in the past 20 years worth diving in to.

Beautiful imaging. Thank you so much for sharing these! The structure of commonplace pressurized flow is so unexpectedly organized.

Hey man, new follower. Windows = bad times in microinch range. Noticed on your diamond turning optical video. Curtains or cardboard could save your next project! Everything reacts differently to heat so 20C is your best bet to minimize uncertainty. Also thanks for the book recommendation video! ~1200 on Amazon but certainly worth it.

the only thing you were doing was shifting the weight of your measuring instrument not deforming your surface . So the issue is gravity not deformation. Whit the rod in the middle you prevented the shifting in front of the tabel not the back. Maybe get a massive tabel you can't easily deform.

This video was recommended to me based on a similar video. The title of magnetizing aluminum and copper was enough for me to click. I am so extremely frustrated with aluminum screws/nails not being scooped with a magnet. I thought my hair would fall out.

Subscibed. So let's start from the begining. ❤

Inception warning: what have you done with that long piece of chips that have spooled? Could it be played somehow? 😅 Another one: get a spool of thin copper wire (used for coils) and get it through a set of rollers that are pushed against eachother using the same techinque.

Can you use two small attracting magnets in the center, to keep it from slipping to the side? They will attract and pull the top down, but the air foil will keep it floating still and now there is no touching.

You can use ball bearing iner race or thrust bearing race for same purpose

Cool!! (Wtf is going on?)

Super cool project! Seeing how it's in aluminium, the center markings is probably slight tear, from a low SFM. depending on the specific alloy, you need serious rpm to get a true mirror quality cut close to center. I'm only really experienced with carbide tooling, but for example, if you want a SFM of 250 two millimeters from center, you'd need just shy of 40.000 rpm.....vibrations being a compromising factor there of course.

12min video with more info than paid courses. Thank you!

Switch the large tubing to small 4mm tubing and mount the distributor to the carriage to minimize parasitic forces from the dragged tubing :)

Is this why it is good at removing dust? It shocks it off the surface like a jewelry cleaner.

I watched this entire video and have no idea wtf is going on (on a scientific level) but it looks pretty cool. I think the google was back to reading my mind cuz i wanted a "dummy" explination why fighter jets in particular get those "smoke" trail things when theyre cornering. I know it has something to do with how the air is disrupted but idk. Its always cool to me to see how the world repeats patterns. The "shock waves" also look like diamonds in my mind and how diamonds form/get shaped into the diamond figure, theres a correlation (to me) between diamonds and the entire world. Or just triangles in general being the strongest structures, it can't all be coincidence? Idk in my very simple mind all energy/power is derived from a triangle... i think im going off in quantom physics which i dont understand but i know it focuses around a center point and triangles/diamonds out. Idk all i know is these triangles/diamonds we dont understand and theyre turning the frogs gay.

Thats cool as hell

So, it's supersonic but not like we think? Just very small?

There's a book on how to make this, free PDF online. Its an old book. Non-ferrous electromagnet

nice thanks. I somehow didn't expect such a simple setup would make schlieren work

Very nice demonstration! I did not read all the comments, sorry if I'm repeating someone notice, but I think, you need to take the exhausting gas temperature into account when calculating sonic speed. The gas, leaving the nozzle, expands and adiabatically cools, so the local sonic speed _in_the_stream_ becomes lower when in the laboratory atmosphere. So, the stream becomes supersonic at lower speeds. If you heat up your exhausting air, you can switch off this effect.

I used to spend time chatting with Dan Gelbart and Dave Sloan, both of were instrumental in developing several companies, including MDA, MDI, Cymbolic and Creo. Dan has an interesting RUclips channel, which, judging by what we have here, many viewers will already know it. Cylo's garage...a nicd place to hang out!

Impressive results, keep at it!

Awesome work, smart design - thanks for sharing!

That sucked

"Orangish line" -- out of curiosity, are you red-green color blind or have you been tested for it? Cause that line was distinctly greenish

How do I get a job like this

Incredible

Will the part not come back into tolerance as soon as it's out of the sun?

Functions like a floating reamer holder

Not sure if it makes a difference on repeatability but if you add a hex to the brass knob you can use a torque wrench to tighten the draw bar. You could also number the cut outs on the “chuck” and aluminum plate so that it is going on the same way every time.

the error reminds of what happens when material just builds up on the bit and then the bit slips back to nominal. so its getting pushed away by the build up. i dont know much about this stuff so forgive my ignorance... if its due to heat/friction maybe try to control the temperature better?

I absolutely love that weird hobbyist equipment is finding a """"""proper"""""" use. Always amazing to see professional equipment making it into hobbyist circles and vice versa.

Thanks for making this video dude

Kicking the dead constant sfm horse some more but you can keep the spindle speed constant while reducing the feedrate as you get to the center. In a big rigid setup, constant sfm doesn’t matter. On your smaller less rigid setup cutting forces may be coming in to play. Tool is deflected on the od because its spinning too fast and is unable to get a stable cut, digs in at the middle of the radius as it finds an optimal sfm to balance the forces, and finally deflects again at the center because it is feeding too fast for the spindle speed causing that tearing/rubbing finish. Another thing to check may be the tool height, make sure it is perfect. Take this with a huge grain of salt, I am only a .0001” machinist. This stuff is really cool, love the content.

How would this work if you're using the compound?

What kind of environmental controls do you in place. For some projects Moore Tool baths the entire machine in the same oil used for machining. How often do you check the cutting tool geometry? Are you using a laser interferometer? Changes in humidity, barometric pressure and, of course, temperature can effect the parameters of the laser. Still, amazing dedication to the science, and practical use of, metro.ogy.

Put it in a Faraday cage.. The electrical loop of probe coax screen and green earth wire wi pick up emf from everything. Maybe earth the puck with a short wire from the probe case. On the lines of everything is a spring... Whats the fundamental frequency(ies) of the anti vibration table? It's going to be low, about the period of the oscillations?

wtf is that thing

Fine thread is actually stronger than coarse thread typ.

If it is a repeatable machine geometry, then reverse it in your program...

did you ditch those angular encoders? why?

how do you avoid negative feedback loop oscillations?

what a cool demo
