Spirograph Machine - Lego Technic

Here I present a Lego Technic Spirograph machine programmed using Powered Up. The powered up controller is used to maintain the desired gearing ratio between the turn table and the inner gear to draw a spirograph that replicates the real original spirograph drawing toy.

That’s such a smart mechanism with those off center turntables, amazing build as always

This is fantastic! I've built a couple of Spirograph designs off Rebrickable and both work well but don't reproduce the same type of patterns as the original gear version you showed. I think you've done a great job recreating the same style as the original. I would love to see a more in depth look at the mechanisms involved in your design! It looks delightfully complex. One idea I have to help with the little hiccup when the pen drops in would be to have it move vertically to engage with the paper, maybe with a linear actuator, not sure how feasible this is though. Anyway great job!

Technic Brick Power: "Hold my beer."

Nice build!

Hey, what's the software you used to render?
