I purchased a Proxxon high-speed (20K RPM!) spindle for milling circuit boards. After devising a way to attach the spindle to my milling machine, I used eagle (and the pcb-gcode script) to generate the G-code for the following simple board. This board contains a microcontroller (the 8-lead device in the center), an 0805 resistor, and several pads to attach wires.
