LEGO-Compatible S50 UID Case for Phoniebox

Turn your Phoniebox RFID cards/tags into LEGO-style physical controls! This 3D-printed case is designed to hold an S50 RFID UID tag, with four LEGO-compatible buttons on top.

Choose the LEGO-compatible version to attach your favorite LEGO minifigure, vehicle, animal, or other LEGO creation. Or use the integrated mounting ring, available in two different sizes, to glue almost any object on top — making it easy to create your own unique music selector.

How it works

• Previous

• Next

• Volume or other custom functions

The exact button functions can be configured in your Phoniebox setup.

Why LEGO?

A traditional RFID card works, but it's not very exciting for kids. With this case, the LEGO object itself becomes the interface.

For example:

🦖 LEGO dinosaur → Dinosaur songs
🚗 LEGO car → Car songs
👨🚀 LEGO astronaut → Space playlist
🧙 LEGO wizard → Bedtime stories

You can create a whole collection of different RFID/LEGO combinations.

Printing

The case is designed as a small, compact enclosure that can be printed on a typical FDM 3D printer. PLA should work well for the case.

Depending on your printer and the desired fit, you may want to adjust the tolerance of the LEGO-compatible parts.
