In this project, we’re making a 3D printed LED hockey puck.

This was inspired by the DIY indoor hockey project by Yuksel Timez.

This hockey puck lights up and makes chips tunes based on motion!

You get a light show each time you hit the hockey puck, so it's still super fun even when you miss a goal.


Either the Circuit Playground Express or the Circuit Playground Bluefruit make this a fun and easy project that uses the built-in motion sensor and NeoPixel LEDs.

The case was 3D printed in NinjaFlex filament which lets you use the buttons to switch between different animations.

With MakeCode for the Circuit Playground Express or MakeCode Maker, we were able to quickly make this demo.

MakeCode an easy to use block based code editor that's great if you're just getting started.
