Each LED clock contains an originally designed circuit controlled by an ATMEGA328p microprocessor, programmed in-house.  The clocks are powered by 9V DC through a standard jack (2.1mm id x 5.5mm od, center positive) and run on less than 1/8 Watt of power.

The clocks are reprogrammable using a standard AVR ISP programmer - please contact us for more information.
