Ever since I created the Spirograph Automaton I remained interested in drawing machines. For this years Christchurch Brick Show I wanted a more compact, easier to build version of the Spirograph. This time I used three motors instead of just one. Controlling the speed of both arms and the table was very easy this way. The Spirograph worked reliably throughout the whole show. The MinuteBot baseplate makes the construction even easier. The building instruction are available for LEGO Digital Designer. More information is available at Rebrickable.
