MiniCamBox

This ia a 1 cm thick case to replace the standard thick design of the Mocrosaft 3000 /pro webcam. A fine compact HD(720p) webcam which you can still buy for under 25 euro. I like this cam because it works ok in most os-s like raspbian on PI, linux, freebsd. Incuding reasonable quality sound.
This one is running for monitoring print-jobs on my Wanhao D4. To get it working i mounted a Pi(1) plus a cheap icidu usb2 hub. On the Pi i installed Astrobox (great render service).

See photo's. The traco power converters are not cheapest you can get (9 euro) but don't need extra cooling or condensators for noise etc.... so you can safely solder them on a wire from power supply to input on Pi or other 5v device... easy.
The powerconverters are mounted on the psu next to the Pi (with the ASTRO sd).
