Wireless LEDs look magical but what do they sound like? In this project, you'll build some maracas with the wireless LEDs acting as both the visual and aural component. You can use them as a fun prop at a concert or add them to your experimental, DIY percussion instrument collection.

The coil sits in the center of the maraca vertically so that the wireless LEDs are always lit.

There are two options for assembly. The first is to use a plastic bauble with a cardboard tube. Since the plastic is clear, you can see the LEDs perfectly. The battery pack also fits nicely inside the tube.

The second is a 3D printed case that closes with magnets. You can print it with transparent filament for a diffused lighting effect.
