Summary

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 uln2803 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.
