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.
Step 1: The Parts
Picture No. 1
- Raspberry PI model B with 512 MByte ram
- Raspberry PI camera

- WLAN USB stick (TP-LINK TL-WN722N)

Picture No. 2
- 7 Port USB HUB
- 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.
Picture No. 3
- Vintage lamps, formal used with a 230V neon bulb. I replaced the bulbs by LED bulbs normally used as replacements parts for the 6,3 V bulbs in pinball machines.
- A bakelite switch to control the power supply
- A momentary switch to control the ATXraspi circuit.
- A vintage meter. Used to display the +5V power
Picture No 4.
