But everything else — clock, memory, and power — are from an Arduino Mega 2560. You could argue that’s two chips, but the board actually has several chips on it.

The hands are actually the Raptor-Reloaded open source 3D-printed prosthetic hands, although XenonJohn has modified them by adding coils of wire that function as magnets for each of the fingertips.

An inspiring Arduino project created by Sang-won Leigh has been unveiled that takes the form of an Arduino wearable device that adds an extra robotic hand to your wrist. This innovative device can ...

He has the processor, of course. But everything else — clock, memory, and power — are from an Arduino Mega 2560. You could argue that’s two chips, but the board actually has several chips on it.
