8 independent microcontrollers generate an oscillating square pulse that is emitted as current and voltage to a coil, that create a variable electromagnetic field. four induction coils capture the invisible field that is amplified once again in to electromagnetic waves sent to speakers, which use electromagnetic induction to convert the electrical current back into sound. spinning the platform and controlling the independent necks, attack sustain release and decay could be achieved
Check out the project page for more photos and an audio recording of 8 x 8 Ω / 1 bit in action.
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.
