The harmonograph is a machine that uses pendulums and gimbals to draw visual representations of musical harmony. Changing the ratio by adjusting the weights creates a variety of geometric patterns.
Mechanical Drawing Machine
Mechanical drawing machines produce visual representations of harmony. Complex geometric drawings are made through the use of pulleys, gears and epicyclic motion. These instruments demonstrate the harmonious union of engineering, physics, music and art.
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.
