Build a Spirograph with LEGOs

From Instructables user robertsseib:

Do you remember playing with the Spirograph as a kid? You know, the funny gear cogs you used with a pen to create endless drawings of mesmerizing quality?

Well this pretty little bot accomplishes virtually the same thing, and it’s really not that hard to build. If you are a Lego fan of any variety, you will probably have all the pieces you need. The one exception may be the electric motor (Power Functions) and the “Turntable” which are slightly more rare parts.


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
