    [queued] Teensy 3.2 Converts IBM Thinkpad 380ED Keyboard and Trackpoint to USB

    Thinkpad keyboards from the 1990's have a resistive strain gauge trackpoint that was converted by the original motherboard to mouse commands. This project uses instrumentation amplifiers that feed the A to D converter on a Teensy 3.2 in order to detect the 380's trackpoint movement. The keyboard key matrix is scanned by the Teensy in order to create a composite USB keyboard and mouse device. The project is documented on Hackaday.IO and Github.
