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.
- Gemma mini microcontroller
- NeoPixel Ring - 24 x WS2812 5050 RGB LED
- 150 mAh LiPo battery (get a few)
- Adafruit Micro Lipo w/MicroUSB Jack - USB LiIon/LiPoly charger or similar charger
- Silicone Cover Stranded-Core Wire in 4-5 colors - nearly anything will probably work here, but this stuff is flexible and easy to work with
- Fast Vibration Sensor Switch
- Soldering iron
- Utility knife / X-Acto / razor
- Hot glue / hot glue gun
- A handful of rubber or nylon washers for spacing
- E6000 Adhesive - available from Amazon or most decent hardware stores (I get mine at McGuckin Hardware)
- Sturdy velcro squares or similar fasteners for battery, battery cable, and counterweight
- A desktop computer running the Arduino IDE, version 1.6.4 or later (at the time of this writing, probably a Windows or OS X machine - it's theoretically possible to program the Gemma from Linux, but so far I haven't had much luck)
- A micro-B USB cable
Assembly is fairly simple and goes quickly, but you'll want to factor in at least 24 hours of curing time for the E6000.
