Lyman Connor, a GE engineer who writes software for turbines and power plants, has always been a tinkerer. Among the tools in his garage is a 3D printer, which he decided to use to build a low-cost bionic hand.
Connor’s quest also took him to the heart of the maker movement, a diverse group of tinkerers, hobbyists and DIY entrepreneurs. One such community is called TinyCircuits, which makes open-source miniature computer boards in Akron, Ohio.
Tiny Circuits designed for Connor with his input, a miniature singleboard solution based on its TinyDuino, a quarter-sized board based on the Arduino microcontroller, to manipulate the hand with his app over a Bluetooth connection. A Roanoke machine shop then built him metal joints and other parts needed for the hand.
An early version of the bionic hand’s electronics were built around an Arduino board.
