Overview

“Ba-DING!” The classic 8-bit chime from our favorite retro video game finally makes a triumphant come back as a Mario question block necklace.

It’s so tiny and adorable you're probably wondering, “How much?” This is custom…you can only make it, not buy it!

In this DIY project, we'll show you how to build the Mario coin sound jewelry so you can wear it and learn about electronics and 3d printing.

This guide was written for the Trinket Mini and Gemma v2 boards. It has been updated to also support the Trinket M0 and Gemma M0 using CircuitPython. We recommend the Trinket M0 or Gemma M0 as they are easier to use and are more compatible with modern computers!
