The goal of this project is to provide everything you need to know to build your own eXtreme Feedback Device (XFD) at a reasonable cost (round about 10 Euros).
See one in action: 20 s video of this controller working in a 3d printed traffic light model (published on thingiverse).
The device here is based on a PIC18F13K50 micro controller from Microchip and a traffic light gadget Pearl Traffic Light.
And as this project is all about CI, here is the build state of this project: 
More Prototypes.
The schematic of the device is quite simple: 
I made a layout for a pcb, but I didn't use it myself up to now. Fabricating a pcb seemed to much effort for the simple layout, so I still use a stripboard.
A list of parts used in the schematic is generated as hardware/XFD.bom. Additionally you will need a piece of stripboard, three LEDs (red, yellow and green) as output device or something similar (see above) a case and an USB cable. Optionally you can add a socket for the PIC if you prefer to not solder it directly.
You can find part numbers and prices (Jul/2012) from Reichelt in the file prices.gnumeric.
- Snapshot build of the java host program (including dependencies): buildmonitor-with-dependenicies.jar
- Snapshot build of the device firmware for 18f13k50: XFD.hex (use with a boot loader), XFD_noBL.hex (use without a boot loader).
- Snapshot build of the device firmware for 18f2550: XFD.hex (use with a boot loader), XFD_noBL.hex (use without a boot loader).
The snapshot builds run on CloudBees
