Descripción
update 2(2016/11/25) added printable spacers and a motor mount plate for 20mm npm motor
update 1(2015/2/6) : added assembly sequence sheet .
this is a simple clock based on a single geared stepper motor which i found in surplus 10 for a dollar... The motor is basically a 1:30 geared motor working at 12v with a 3mm shaft. The single motor is driven by a attiny2313 and l293dd circuit with the coded written in arduino ide. The single motor moves a gear train which in turn moves the minute ring and hour ring. The attiny pulses the motor every minute to move the minute wheel and the hour wheel.
