HSC2011/Building your own EduBuzzer
aus Metalab Wiki, dem offenen Zentrum für meta-disziplinäre Magier und technisch-kreative Enthusiasten.
In order to build an EduBuzzer, you'll need
a bunch of electronic parts you can obtain from your supplier of choice
equipment for etching a two sided PCB (as an alternative, you can order it just as well)
a rapid prototyper (3D printer, e.g. a makerbot)
a programmer for AVR microcontrollers (any AVR microcontroller with a bootloader will do, especially an Arduino -- c.f. the Arduino ISP tutorial) with appropriate software, e.g. avrdude
