Build a prop replica of the Memory Gun from the Gravity Falls TV show. Powered by the Feather PropMaker RP2040 and CircuitPython, this 3D printed prop lights up and plays blaster sound effects.
The 1.3in OLED screen displays a list of audio files stored on the Feather internal flash storage. Use the rotary encoder to cycle through the list of audio files. Press the button to trigger sound effects and light up the LED noodle.
The prop parts are designed to be 3D printed without any support material. The light bulb (plastic holiday ornament) features an LED noodle that is fitted inside 3d printed holder.
The parts are 3D printed using various glittery PLA filament without any sanding or post-processing. The pink "blaster shield" is laser cut acrylic, but can also be 3D printed in translucent PLA filament.
The Feather PropMaker RP2040 is housed inside the canister with access to the USB-C port for battery charging. A slide switch is hidden right below the USB-C port to power the prop on and off.
