You can build the iconic Energy Sword from the Halo video game series and TV show.
We've upgraded our original project to feature motion activated sound effects powered by CircuitPython and the Prop-Maker Feather RP2040.
This dev-board is our favorite go-to that’s designed for making prop projects. It’s got the RP2040 chip with built-in audio amplifier, accelerometer and 5V NeoPixel level shifting.
A 2000mAh lipo battery will provide several hours of energy and can be recharged over USB.
The 3D printed blade is 86cm (34in) tall and the whole sword weighs just under 1 pound.
CircuitPython has made our Prop-Maker projects easier than ever thanks to our new demo code and libraries.
Dev-boards with CircuitPython are great for props because they load just like a USB flash drive so you can easily edit code and drag and drop audio files.
When the prop is idle, the LEDs slowly fade with a looping sound effect in the background.
When the accelerometer detects a swing, it triggers a blast-style lighting effect with swooshing sounds.
