Well Atmega168 cannot match J.A.R.V.I.S but can help to make some cool effects. Daniel has shared his home built Iron Man suit which features Atmega168 microcontroller. It controls Visor servo and Visor Eye LEDs. It also monitors visor up/down switch.
Probably the biggest work here is the suit itself. I must say that results are great. It really looks convincing. Why not keep upgrading the suit with more features to make it unbeatable.
