Overview
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.

Assemble
Place Lipo Battery
Orient the battery so the wire connections are facing down.
Align Circuit Playground
The battery port aligns with the flaps on the case.
Attach screws
Align the flaps on both parts of the case and fasten four M3x12mm screws to each standoff.
Plug in Battery
Pull the lid flaps back to plug in and to disconnect the battery to the Circuit Playground.
To close the port opening, push the larger flap behind the shorter flap.
Charging the Battery
The battery connector can reach out of case and plug into a USB lipo charger to recharge the battery.
Hockey Blade
The hockey blade press fits into a 7/8 diameter dowel.
Use an M3 screw to further secure the blade.
