New Guide: John Park’s Crickit x LEGO Harmonic Drawing Machine @adafruit @johnedgarpark #adafruit #lego

Create beautiful complex harmonic curves with this drawing robot! This new guide will show you how.

Different from a roulette curve drawing machine, such as a Spirograph, a harmonograph/pintograph generates Lissajous curves that are bounded by four corners.

By adjusting the pivots and motor speed ratios using the Circuit Playground Express buttons, you can make different types of drawings.

You’ll even get to merge the worlds of Crickit and LEGO with this TT motor-to-Technic cross axle! And, a very stylish 3D printed Crickit-to-LEGO plate finishes it off.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
