Overview

Chirp chirp! Make this delightful sound-making plush toy with the Sew-Your-Own Owl Kit and GEMMA plush toy guts kit. This simple circuit uses a tilt ball switch to trigger GEMMA to play a sound on the small speaker. You can program your own circuit to make other sounds too, so you can even mod a plush toy you already have!

This is a beginner level sewing and soldering project. This tutorial has detailed photos for each step of circuit assembly and installing the circuit into the toy, and the owl kit comes with detailed printed instructions recommended for slightly experienced stitchers as young as eight.
This guide was written for the Gemma v1 and v2 boards. It can also be done with the Gemma M0. We recommend the Gemma M0 as it is easier to use and is more compatible with modern computers! The wiring is the same.
