This week, we'll be milling out a PCB out of copper plate and soldering the electrical components to make a FabISP -- in-system programmer for AVR microcontrollers, i.e. you can control other boards using this circuit. This time, I collaborated with another M.Arch student, Daniela Covarrubias.
1/32 End Mill.
There are a couple of ways...
Start with small components first.
AVR Green Light + Running script.
