Title: PC Power Supply to Bench Power Supply Mark II
Post by: somunny on September 03, 2008, 09:48:27 pm
This is the second power supply I've converted using this tutorial (http://www.wikihow.com/Convert-a-Computer-ATX-Power-Supply-to-a-Lab-Power-Supply).

The fan on the top was relocated from inside to make space for the wiring.  I still need to add some feet and label the outputs (gotta order some 'white on clear' label tape for the P-Touch).

Outputs: yellow=+12VDC, blue=-12VDC, black=ground, red=+5VDC, white=-5VDC

These really come in handy when you need to test LED arrays.

LOL. That's funny that they have a tutorial. Honestly, I never really thought to use posts and cut everything short like that. I have a PSU buried somewhere where I built a harness that's simply shorted with a jumper and added pigtails and alligator clips. Basically a fire hazard waiting to happen.  >:D

Thanks for the link, there's a few ideas I never really considered before.

I have an old AT power supply that would be perfect for this.

Nice site.  They also had this:

Could be handy for some folks around here.

This reminds me of my shed project 6 years ago.
I used a concrete floor, which is great. Only complaint I have is it is way too small.
its 12 foot by 16 foot, wish I had made it at least 16 by 20.

I checked and unfortunately they do not have a tutorial on hauling wood in a pickup truck.

Be careful. Some city codes have specific limitations on number of sheds, size of sheds and location of sheds. Even if it is a "floating" shed like in the tutorial. Even worse, some city codes have a limitation on how high a shed could be be above a fence line! IOW, a short fence means a short shed.

I didn't include it on the the last one I built and never missed it so 3.3V didn't make the cut this time around either.

The 3.3V wires are cut back and rolled up inside if I ever had the need for them.  I mostly use the 12V and 5V.

At least PBJ got the joke... :)
