Eagle 6 board and schematic are in the pcb/ folder. There is also a design for a "programming cradle" that mates the test points on the MIDIWidget with a AVR programmer for ISP.
A public CircuitHub project is available for on-demand manufacturing: https://circuithub.com/projects/CodeandCopper1/MIDIWidget
