This Spirograph Automaton is a LEGO drawing machine based on the the popular toy and the ideas of PG52. This version extends previous designs by using LEGO Mindstorms EV3. The Spirograph Automaton knows when the pattern is complete and lifts the pen at the right time. The machine can produce 64 different design. You no longer have to observe the machine to complete its drawing. The gears are optimized to give fast results so that the children do not have to wait too long. I also build a coin detector that triggers the Spirograph Automaton. Instructions are available at http://www.scribd.com/doc/220028123/S...
