Fun LEGO Technic build! The drawing machine creates spirograph-like designs using a single motor, a worm gear, a crank and zero code. Shared by Brick Trials on YouTube:
A turntable spins the paper while a crank swings the pen arm. The two speeds are slightly out of step, so every stroke lands a few degrees further round and the drift alone draws a dense spirograph flower in about three minutes. The 4K video shows the full build with real brick sounds, then the machine drawing.
Thanks for sharing!
