- Received a short introduction to PCB CNC from user:bkubicek.
- Had a look at the Bauteilsortiment -- they have almost everything we need. notable exceptions are an rs485 serial driver and an RFM12 (there are three RFM12B, though; considering switching to 3.3V).
- Built a minimal programmer using an arduino and the layout from the ArduinoISP tutorial. Another tutorial was helpful too.
- Using this configuration, sketches can be uploaded to the second ATmega168 with the usual Makefiles (it helps to set the F_CPU correctly, though, otherwise the delay function produces slightly off results)
Next steps are uploading the V-USB bootloader to the ATmega and experimenting with USB HID; ordering missing components.
