Wireless MIDI Capable Interactive LED Juggling Balls DIY

OK, I'm hopeless at trying to juggle, but I thought this was just way too cool to not post here.

Create your own interactive, wireless musical LED juggling balls using CircuitPython and the low latency ESP-NOW protocol.

These juggling balls shine bright with NeoPixels, and can wirelessly trigger MIDI notes based on catch detection with the LIS3DH accelerometer, and a Feather board to bridge messages to your computer or USB Host synthesizer. You can code any note pattern or interaction you like in CircuitPython.

While there are commercially available LED juggling props, there are none that send MIDI messages to a host computer or bridge are currently available, so let's make our own!

This project was inspired by this performance by renowned juggler Jay Gilligan.

  • Juggling is one of my oldest side hobbies - though mostly now just for a party trick. I used to have a set of LED balls for juggling and always enjoyed performing a routine with music. This looks awesome and a good time for a portable festival setup.

    I'm gonna have to try 3d printing one of those balls just for the heck of it. I even have some translucent filament I can use. The idea of being able to send midi using the accelerometer sounds so freaking cool, but I'm not going to go as far as trying to make 'em work.
