Overview

Summon Sand Worms

You can build a Worm Thumper from the movie Dune !

This project features a motion activated servo powered by CircuitPython and the Prop-Maker Feather RP2040.

PropMaker RP2040

This dev-board is our favorite go-to that’s designed for making prop projects. It’s got the RP2040 chip with a built-in audio amplifier and accelerometer!

A 2000mAh lipo battery will provide several hours of energy and can be recharged over USB.

CircuitPython

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.

Motion Activated

When the accelerometer detects a drop, it triggers the servo to spin and actuate the center rod to push the top of the Thumper up and down. The Transducer plays a thump sound, adding to the thumping effect!

Parts

Video of a white hand pressing a button to briefly turn an LED strip into white lights. Also wired up to the microcontroller are a servo motor and a speaker.
