I use counter pieces for my sandpaper lapping plates as you can generally average out the surface imperfections. Also makes for generally good enough rough inspections plates for like cast things so you don’t scratch the good one Also your DIY repeatometer is not enough to inspect to even like B grade, a really wide tenths dial works enough to see if you have big dips (anything over like 3 tenths means toast for real flatness)

I picked up a very similar tool set from Amazon, and used it to swap connectors on an ATX power supply. As he demonstrated in the video, the single-pin tool did the trick. I was able to work it down into each side of the pin, rocking it slightly to flatten the tabs. I then gripped the nylon connector with pliers and pulled out the wire. Be aware: the tradeoff for using a cheap tool instead of spending $35 or more on a better depinning tool, is that you will likely end up with at least one hole in your finger. There are sharp edges on the depinning tools, and on the connectors once you pull them out of the housing. After cleaning up the blood, I did the following: 1) Wrapped electrical tape around the top of the depinning tool (mine was just a bare metal ring with a blade on one end) 2) Wore gloves 3) Gripped the housing with pliers while I pulled on each wire I was able to finish the job with no more bleeding.

Lawrence Sparey said a peice of plate glass was what he used. Probably good enough for who it’s for!

they dont work whatsoever

I'm sure my original competition pro buttons worked the same, I think it's useful that way for left and right handed players, I don't know anything that uses a second fire button.

Looks familiar!

just got mine yesterday thanks for the video.

And seems to support button 3, like Amiga and almost all Commodores and Atari do. I could make one of these myself, or plug it in and use a program. But it's kinda nifty to have on the bench.

That TAC2 joystick, looks very nice but doesnt have micro-switches, right?

I bought one. Complete waste of money as it didn't even work straight out of the box.

I've got several grave masonry offcuts. They are all terrible. I can tell they are bad even using a long school ruler. I'm thinking about getting a new float glass piece. My previous one broke.

This one just cropped up on my feed, so yeah, here's me commenting 5 years down the line, not so much for Benjamin, but for those coming later. There's people here commenting that this is not a good test, and to a certain extent they are right. If this is a flat(ish) surface with a maximum deviation of ±25 microns over 10 cm, or a concave spheroid(ish) surface with maximum deviation of ±25 microns over 10 cm, , or a convex spheroid(ish)… you won't be able to tell using this setup. A machinists level can tell you, and an autocollimator can tell you, but that's about it. However, it's unlikely to be a spheroid, which is usually achieved by lapping (see telescope mirrors, etc), it's far more likely to be flat(ish) But. If what you want to do with it does not require more accuracy than that, it's fine. And most home shops do not require more accuracy than that for most uses of a "surface plate". Maybe if you're reconditioning machines, or measuring pieces that require high accuracy. Most of us aren't doing that. Most of us will be using it with a height gauge for measuring or marking out. It's fine in that respect. It'll get 90% of what you want done. What I would be more worried about is surface durability. Anyway, it's a good example of what you can find "over the counter" (if you'll excuse the pun).

Most home machinists don't need and can't achieve any better accuracy than your countertop cutoff. Great demo! I'm working on naval guns that were made between 1910 and 1942 and the quality of machining on the original parts is amazing but as long as I can hit within .0005" the parts fit and work.

Promo'SM 🎉

You could get 3 and rub them together for even greater accuracy!

the moment the button fell out was pure gold. keep up the good work

I'm wanting to make a converter for my Archer Amiga joystick with an esp32 to convert from the 9pin to usb. Just need to get the right esp32 that can do HID

I made 1 from scratch, shooting for .005 for woodworking, but easily got .002. The indicator setup you used cannot pick up widely-spaced holes and high places. I used a home-made precision spirit lever with 3-point contact.

This specific, particular model DAC, XDA-2, had the right design here. It's a real shame Emotiva didn't keep this model & continue to refine it. Full size, extra inputs, balanced & a toroid. If they had dumped the headphone section and volume control (use gain settings) and put the money into socketed, upgraded opamps, for example, they really could have kept a winner. They also could have continued to improve USB and optical (to ir? ip? glass fiber coming soon). I like the Bit Rate display. Too bad. I've found 5 other used DACs with about equal designs (easy picture searches); 1. Benchmark DAC1 (w/USB if possible) +-$500 used Incredible quality. none better. 2. Parasound ZDac v2 DAC +-$300 3. Bryston BDA-1 DAC +-$600 Is what the Emotiva was copying. 4. SMSL SU-8 DAC +-$225 chinese, but used so O.K. 5. Rotel rdd-1580 DAC +-$450 be cautious of the drivers I can't make a claim as to the sound but the constructions make them attractive as used pieces. (if that's even possible with a DAC) Acid Jazz, Funk & Brass 🔈🔉🔊

I do assembly fh200 for 7 years. we made start from switch case.. Until cleaner base..... I miss my job. As well 😢 n now iam jobless here 😂

Oxtoolco has some videos on accurate surface plate measurement and conditioning. Robrenz might have a few and possibly the 3 plate method with some basic theory. Overboard for your purposes but interesting non the less. Iirc the origins of precision is another one.

Great start! Looking forward to the rest!

Nice work :) I worked for Phoenix Microtechnologies back in the day. It looks like you have a coin cell to run the RTC. The original part we used was a VL2020 *rechargeable* battery. (going from memory). If you was to use a (non-rechargeable) lithium coin cell you will want to remove the charging circuit to avoid any nasty bangs.

You’re a braver lad than I. We all know what my hand looks like under that microscope 😜

How is it on A/C?

Nice package

😢😢😢

Looks great mate

Nice work. I'm working up the courage to build one myself 🙂 Looking forward to the next episode.

How does it perform on high current DC?

Just found this video... Freakin hilarious!! That's great.

Nice job!

This just a piece of scrap he aquired without lapping it . Lucky that flat

Lock picking lawyer is the best 😂 love his vids

I saw these and was a bit unsure about how well they would work. Having seen this, I've just ordered one. Cheers for taking the time to make and post this.

Dont know about this system. I think the main problem with keyboards is the stuff that falls in between keys, dust and hair

I'm glad this came in my recommendations and I commented on it cos I just had to come back to it haha... this is super relaxing, and I've been listening to asmr for years and this is probably one of the most relaxing videos ive watched!

Cool hobby... how long have you been doing keyboard stuff?

Satisfying!!

Did you see Emotiva came out with a new XDA3 DAC I’m curious on the differences

Im surprised how precise that clamp is, given that it measures magnetic flux. Its really well calibrated.

Awesome video. I'll have to find a place to get some granite near me. Thanks for sharing.

That's really cool. It's definitely unique but at the same time actually really practical. Maybe there's a case, for a case that's like that low profile. With the A3000 style a1500 cases around out there. Maybe a more slim line a1000 styled solution could gain some ground. The A1000 really was the nicest looking Amiga. Yeah the a3000 style is cool. But the A1000 is clearly the best. If I could get an annual l Amiga back in the day though with a 1U profile. Like Mac SE030 type case in size. Yeah I would have loved that

hey bro, are you in qld ?

"PromoSM"

VGA card for XT emulator? Doesnt work with AmigaOS?

🤔 'Promosm'

Hi, you really did a terrific job. What a neat result, all components perfectly placed. My compliments! Cheers, M

I wonder how much it would've cost to have pcbway populate the board as far as they are able (minus custom chips, etc).
