 Build the sword that seals the darkness, and defend your kingdom with Adafruit's RP2040 PropMaker Feather. This iconic sword has been upgraded to be much easier to build. Additionally, the assembly is even more durable. The new dev board packs all of the features into one, making this project even more enjoyable to build. The PropMaker Feather is powered by the RP2040 chip and features better audio quality with an I2S amplifier. With 8MB of spy flash, USB battery charging, and screw block terminals, it's the best dev board for building cosplay props. The circuit python code has been revised to handle the new pinouts and features adjustable settings for the accelerometer in NeoPixels. We think it's a great source for building similar props that feature motion-activated effects with LED animations. Get the parts to build this project, links are in the description. Dedicated 3D printed mounts, secure the electronics, and the blade utilizes hardware screws, making it a battle-grade prop. Dual strips of NeoPixel LEDs provide total brightness, making it eliminate any darkness. To learn how to build your own, check out the guide at learn.aderfruit.com. The hilt and blade parts are secured together with stainless steel screws for maximum durability. The built-in standoffs and wall thickness have been increased, making the parts much more rugged. Each component has its own mounting plate that perfectly fit inside the hilt with enough room to house the various cables. The two halves are joined together with hardware screws, making it serviceable in case anything gets damaged. To garnish the sword, a piece of green paracord wraps around the handle for a better grip. We had a lot of fun upgrading the master sword and felt it ease letting the kids cosplay with it outside. We hope this inspires you to check out the ARPY2040 prop maker feather for your next cosplay prop.
