Software

The Arduino sourcecode is available on Github. Arduino-Tiny Core support files needs to be setup for ATtiny84 and the enhanced pin change interrupts for tiny processors library is needed. I used AVRdudess and a ISP-PogoPin connector for downloading the firmware.

Hardware

The EAGLE schematics and board files as well as the CNC drill/mill and LaserCutter (for SMD stencil) files are available on Github.
