A couple of month ago I bought a R-PI computer board in a kit that includes the board, the PI camera and a 16 GByte SD card. I tried around and found that it is a very nice peace of technology. But I was not able to find a use case for that board.
Last week I have had the idea to build a NAS system for use on conventions and exhibitions to store music, videos and some how to´s on it. In the cardboard there was a glas dome and the idea was born to build a computer with nearly all parts visible.
Switch mode power supply, providing +5V switched, +5V permanent, +12V, -12V (VOLTEK SPEC7188B) more infos here: CLICK. The power supply acts like a ATX computer power supply. It provides +5V a a permanent voltage to be used to switch the power supply on and of via a special input wire.
