Jodrell development board
This is the original development prototype for the Jodrell clock. Simply assembled on a sheet of plastic, it functions as a clock with the moving pixel dot around the perimiter. I made it to allow me to write the firmware that runs on the Arduino board to control the LED ring and it also has a WiFi connection for timekeeping.
It works perfectly well as a clock, albeit looking a bit Heath Robinson! Measures 25cm wide by 27cm tall and comes with some instructions.
Sold as a development prototype, so there is no warranty and strictly sold as seen.
