I won a overhead projection panel on ebay a while back. But, I didn't get the power cable with it. Does anybody know what voltage it probably takes(I have a variable dc supply that does most things between 3volts and 12). I haven't been able to know if it works. I really have no use for it anymore, but I want to test it before I put it in the trading post.So if you are interested, I will have it there soon.

Well plug it in and fire it up start at the lowest 3V and slowly move up til it works once it works dont go any higher

this is if your PS has enough amps.

i did the same thing on a wireless router I had til my brother borrowed the PS changed the voltage then tried to put it back in the router and it lost all its magic smoke (dang kids these days know nothing)
