I've just received the first PCB's from BatchPCB for the BlipBox project, very exciting!
The BlipBox is not exactly a 'duino, but uses the standard bootloader and is programmed using the Arduino environment.
The box is a touch screen and LED display unit, in short. The idea is to create an open hardware and software platform for people who like to experiment with this type of device. Open source, of course.
In the near future there will be better diy instructions available, in the meantime I would love your feedback on schematic and pcb design.
