what is this type of circuit board called - how are the traces made?
25 replies and 6 images submitted. Click here to view.
It's just a basic PCB. There are several ways to make them, but you could google "toner transfer" and "photographic method pcb" for the starters.
It's a regular copper clad board and it looks like the circuit was drawn on with a permanent marker then etched and then tinned to make it silver.

Markers are shit and rarely work well, I've had much better results with toner transfer.


Does some electronic component/solenoid variation like this exist?

I realize I can use a servo motor, but a solenoid like device would be faster and more compact.

i've seen this kind of thing inside computers as an anti-tamper device. they prevent anyone from opening the computer case unless the solenoid is retracted.

Help identifying wood.
Timber flooring from 60yo house in south east queensland.

Im ripping up shitty layers of carpet and lino off it. I lightly sanded a patch of the floor with 320grit and wet it for the photo.

Not sure if its a waxy type of wood and it needs a special sealant or if i can just throw a normal poly coat on it after a pass with the belt sander. Also, water based or oil based poly?

Yep, that's wood.

Do you guys have any ideas for assembling gift packages? My friend and I are planning on sending some to eachother but I'm not sure what they'd like.

Does anyone else here like assembling them?

What type of stuff do you find works the best?

What exactly are you asking? What kind of gifts you should give your friend? How the hell should we know? What does your friend like would be a good start. Do they like video games? No? Don't send them a video game. A Gail safe gift would be a blow job, send them one of those.

Sup diy. I have always wanted to be a jeweler as a hobby ever since I had a job selling jewelry 15 years ago. I am finally going to start getting my tools together and I am curious as to if anyone here knows anything about it. I really would like some ideas on where to pick up scrap jewelry I can dismantle and melt to have my own metal stock.

Should prolly start with silver or copper rather than gold since they're way cheaper.

I bought two pairs of boots online: One is supposed to be a 9W and the other one a 10. I'm normally a 9.5, they didn't have that size in stock.

The 10 is definitely too large, I can feel my foot move around too much. The 9W fits perfectly except when I walk in it the top part/welt starts creasing and digs into the top of my foot. Its a bit annoying when it does it, I can feel it on top of my foot every time the shoe flexes.

Should I try to stretch out the 9Ws until the vamp "flexes" more or opens up? Like I said the problem is that the vamp...

Why not just put them together to average it out to 9.5

If you are working on your feet most of the time think about swelling too. Boots that fit perfectly in the morning might just feel too small in the evening.
Thick socks?
Pack the toe with material?
A boot too small is a bigger deal than a boot too big.

Hello /diy/ I woke up the other day to see that 2 rows of tile on my kitchen floor have buckled and are raised up now. Two rows of 5 tiles and partial tiles against the dishwasher. Two full tiles and one partial have cracked as seen in pic related.

Is there a way I can just remove and replace the cracked ones and get the others to lay flat again? There is some shit on youtube about drilling holes in the grout and spraying some glue shit under the tiles but I don't know how I'd force them back flat on the floor again.

Any help is appreciated.

You woke up to this? As in the tiles were level and unbroken when you went to bed the night before?

i am trying to identify this broken SMD Part. It was on the pcb of a fluke 87 IV i got for free because it had suffered falling damage. I already identified a broken smd resistor but i have no clue what this thing could be.

Looks like a resistor. See if you can measure the broken parts with another meter.
Is there any part designation on the board? If so, you could try calling Fluke and asking what that particular resistor on that meter is.
No Parts designator anywhere on the board. And since the part is broken i cant measure anything, even if i push the two halves together very hard.

Didn't see a tie dye thread. Does anyone know if oxiclean will fuck up tiedye? Just got this sweet sweatshirt but I don't want to fade the colors.

Hey /diy/,

I recieved a Tokoyo Flash RPM a couple of years ago and over time it's accumulated grime underneath the glass covering. I really want to send it back to the company to get it repaired and what-not, but they won't do anything since I don't have the original order number.

Have any of you dealt with a watch like this? I'm afraid to take it apart because It's not exactly the conventional watch. I've looked online for other people taking it apart, but cant seem to find anything on the internet.

Would you guys know how...

Well, I went out a few hours ago and sat on a massage chair. The way the chair put pressure on my calves made me wonder if you could make artificial "muscles" which worked with air. Once I got home I googled "pneumatic muscles".

I've been reading about them a bit but I'm not an engineer, so, /diy/, tell me about em. What are they commonly used for? I also read the proper term is PAM in wikipedia, is that also used as the common name? And finally, would it be possible to make a prosthesis which felt closer to an "actual" leg with them?
3 replies and 1 images submitted. Click here to view.
If I remember correctly, those are really hard to control accurately, which is necesary for any type of artificial limb. Plus, you need a compressor to move them, making a PAM prosthetic very unwieldy.
human muscles work in pairs, your brain has a feedback loop that controls proportionally the extension of each muscle to move and hold in the right position.

if you fill an air muscle with air it would go from one extreme to the other.
you would need to control dynamically the pressure in the 'muscle' to set the position and then adjust it continuously as you change the outside loads and forces.

but yeah, it would work kind of

sup /diy/, I've been through some parents stuff and found some audio equipment I remember we had when I was a kid.

I found this soviet Vega 323 stereo turntable among other things. I'm wondering what to do with it since it doesn't work properly. Dad says it's a piece of junk anyways because it's rough to the LPs. The audio quality isn't very good either because low quality needle (although this could be replaced). But apart from top acrylic cover it's in great shape visually, nice wood and lacquer, plastics are nice and solid too. I thought I could build a home media center in there after I gut it.

It also comes with a pair of speakers which are shitty, maybe paper membranes. But same nice wood and lacquer and textile front mesh. I thought I could replace the speakers inside with something of higher quality.

Any other interesting things I could do with it?

The back already looks like it could house power supply, mobo I/O shield, etc.

Since the case is quite low, I'd put some drawer rails on the sides and make it slide out for maintenance.
>(although this could be replaced)

Looks like a TAP style cartridge mount to me, with a straight tonearm.
That alone means its a very low quality player in the first place.

Have fun playing with it, but dont dump a bunch of money into it.

As a product of era that didn't plan obsolescence, it comes with complete schematics so it could be repaired to original state... possibly even upgraded to produce higher quality output if some components are replaced but I wouldn't have use for LP player anyway.

Hi I have a cheap pair of sweatpants and the seam on one of the bottom legs is starting to go I want to know how I can keep the bottom leg stretched open while I do the sewing and I'd also like to review how to finish off the stitch since I'm not very good at that.

You are right, some people are useless.
Just tie the stitch back on itself. If you fuck up, repeat until it's right.
The thing with this is that I need to keep the elastic stretched to it's maximum length while I do the sewing. Sewing is already a two-handed job, so I was wondering if anyone has tried this before.

>Just tie the stitch back on itself. If you fuck up, repeat until it's right.
That's what I've been doing when I've sewed stuff before. It sometimes comes undone, so I thought I was doing it wrong.
