I played a lot of Ultimate in college, and I’ve wanted to build a programmable, sensor-equipped disc ever since. This project is intended as a basic starting point for DIY disc projects: It can be programmed in the Arduino IDE, it looks cool when flying, and it responds to being thrown and caught.
The Flashflight Disc-O, designed in Boulder, CO and widely distributed by Nite Ize, is a good quality disc with an RGB LED and a couple of coin cells mounted in the center. A handful of fiber-optic light pipes run from the center out to the edges. At 185g, it weighs a bit more than a standard Ultimate disc, but generally flies well and has a good feel.
I decided to modify one of these since I figured I could repurpose the light pipes.
The end state of this project is less of a finished product than a starting point for fancier, more durable blinky discs, but I think it’s a pretty decent start.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
