Get to know your kit
Before you begin, have you read How It Works? Its not necessary to understand all the technical aspects of the design, but you should get a feel for how all the pieces fit together and what each part you are about to assemble does. OK, you read it? Then lets begin.
There are two circuit boards in this kit. The Sensor Board is designed to fit on the typewriter's crossbar and detect keystrokes, while the USB Interface board is designed to control the sensor board and send USB commands to the computer. They come as blank PCBs, so we'll need to solder the parts on, then connect the two boards.
