Anyone have any old computers or computer power supplies lying around? I'm looking for a couple for a project.

Thanks

What wattage? I have a box full of them here beside me. Also the pom-pom did not make it. Not sure why as the rest of the softies are doing great.

medic29 · #3 09/19/2007, 09:17 AM

Wattage can be anywhere between 300-450 would be great.

As far as the pom-pom...that happens; I had that happen to a couple of mine. I'll let you know if I get one attached to a small rock here in the future.

I've got an old 8088 or 2 buried in one pile or another.
Heck, the other might even be a 286!!!

No idea what power supply might be in them.

You're welcome if you want them. Maybe trade for
a couple holes.

Man, just threw out two old computers.
I'll look to see if I kept the power supplies.

You will probably be topping out with 300s from most people as anything bigger is usually in a machine that works. I think I do have an extra 300 or two if you don't mind contributing to the fund to help me buy a new 500W.

Rick I will check my cache of old computers tomorrow while on campus. I will let you know if I see anything. You working tomorrow around 3pm or will you be off. If you are off...could you meet me on campus near my lab (something I have what you need)?

medic29 · #8 09/19/2007, 05:59 PM

Vitaly: I'm off and can be there no problem.

bpeugh: I'm hoping to not spend cash on these; but not against trading labor, etc., like cutting metal or giving out frags.

Icashman that would be cool

lglamb that would be awesome; on the holes...anytime, just let me know.

Just out of curiousity, why do you need 300+ watts of power in 12, 5 etc volts? That's a lot of computer fans you could run

I will also look to see if I have any around that I can give to vitaly to give to you.

Working to make a CNC-Foam mill and CNC-router. I need the power supplies to run the steper motors, etc.

eshook · #11 09/19/2007, 11:13 PM

medic,

A 250-300W PSU will work fine for a foam cutter (unsure on the router) I built one a while ago for RC Airplanes and it worked just fine with a small PSU. Unfortunately I threw it away before moving here.

If no-one can find a PSU for you I probably have a spare one sitting around. I tossed most of my computer parts in the move, but I probably still have one in a box.

Good luck finding chromium wire. I used twisted stainless steel and it worked decently, but I would have preferred chromium.

webbstock · #12 09/20/2007, 08:55 AM

Chromium wire is sold by lots of laboratory supply companies (it's often used for innoculating loops etc.)

Let me know how much (length) and what diameter you need and I can see if I have some laying around.

Below are links for some vendors (I don't know why the price is so varied)

medic29 · #13 09/20/2007, 10:11 AM

As far as size....I'm thinking 0.010" (30 AGW) or 0.012" (28.5 AGW) or something similar. Initially, I think the length I would need would be no longer than 36". If you have any around this size lying around, please let me know.

eshook if you have any suggestions, please feel free to post.

bpeugh · #14 09/20/2007, 01:57 PM

It is just that the second one is actually IN something right now.

webbstock · #15 09/20/2007, 03:37 PM

I have about 5 feet of 24AGW nichrome wire.

medic29 · #16 09/20/2007, 08:42 PM

That would probably work. I'm still in the constructing stages right now.

webbstock · #17 09/20/2007, 10:35 PM

The wire is yours.

medic29 · #18 09/20/2007, 11:04 PM

Cool, thanks!!
