 Become a jedi or sith and build your own lightsaber with 3D printing and electronics from Adafruit. Powered by Adafruit's RP2040 PropMaker Feather, this iconic prop just got a whole lot better. The all-in-one dev board is engineered for making props with motion-activated lights and sounds with better sounding digital audio and a lot less soldering. It's our easiest build yet. This new lightsaber features a color changing mode so you can experience a new vibe whenever the mood strikes. The RP2040 PropMaker Feather is Adafruit's best dev board for your next prop build. Featuring the RP2040 chip, it's got a 3 watt digital I2S amp for excellent audio quality, Neopixel driver and USB-C for battery charging and programming. The hilt was redesigned to be more ergonomic and the parts screwed together for an easier assembly. The pommel can be unscrewed and the feather slides out of the hilt for reprogramming or charging the battery. The parts can be 3D printed without any supports using filament or you can 3D print them with a resin-based 3D printer. If you don't own a 3D printer, you can use an online 3D printing service. We had these parts printed on an SLA 3D printer using black resin. The service also sanded the parts for a smooth matte finish and the parts only cost us $30. The CAD model is open source and parametric so you can customize the design or use the models of electronics to create your own. Programmed in Circuit Python, the code, libraries and audio files are all accessible, making it customizable on just about any computer. The onboard accelerometer is used to read movement and tap detection for the swings and hits. The button uses the debounce library so that a long or short press can be used for cycling between the different modes. Long press to go in and out of the color changing mode. The background audio lets you know when it's active and the RGB LED matches the color of the neopixels. Just plug in a USB-C cable to start charging and the feather shows up like a USB drive making programming much more accessible. We think Circuit Python is the best for making advanced props even if you're just getting started. To learn how to build your own, check out the guide at learn.aderfruit.com. We had a great time remaking this project and brought it to Star Wars Galaxy's Edge at Disney World. Being able to go from Jedi to Sith was super fun and the kids really enjoyed cosplaying with it. We hope this inspires you to check out the ARPY2040 prop maker feather for your next project.
