Im bumping up this post for a couple reasons. My main questions were all answered, but I have some more more questions for the final refinement of the project. First, Id like to respond to Shax.
For a living I fix digital cameras. Back when I was less experienced, I got shocked by the flash capacitors somewhat regularly. A typical flash cap is rated around 300V and 300uF. I even got shocked by 2 once. Anyway, to put things into perspective, how do the caps in ATX power supplies compare?
So to try to put some of your worries to rest, Id like to say a few things. First is, I know how to discharge capacitors using a discharger. Second is, I did not specify that I have to be working inside the casing. Although that was the original plan, I now am considering having all of the re-wiring done externally. Third, I am under the impression that turning on the power supply (shorting green to GND) when its not plugged in discharges at least most of whats in the capacitors. And lastly, all of the power supplies I have have been sitting around for quite a while. BUT, if you want to share any further safety procedures they would be very welcome.
OK now onto the further questions I have for the refinements of this project. First, I would like to know a source for some digital meters for this. Most important are that I can get a matching set for various voltages and amps, and a relatively cheap price. Also important would be ease of including these in the project (ive seen some that seem to have way more pins than I need).
Mainly the other thing I would appreciate some help on choosing is some sort of enclosure. It would have to be larger than the power supply, and relatively easy to work with. So it would ideally not be metal, or at least the front and back should be something easier to work with.
Thanks for any suggestions.
