We shared Dennis Mellican’s overly effective anti-burglary project last month. Now he’s back with something a whole lot more musical and mini.
Inspiration
Dennis was inspired by other jukebox projects that use Raspberry Pi, NFC readers, and tags to make music play. Particularly this one by Mark Hank, which we shared on the blog last year. The video below shows Dennis’s first attempt at creating an NFC Raspberry Pi music player, similar to Mark’s.
LEGO twist
After some poking around, Dennis realised that the LEGO Dimensions toy pad is a three-in-one NFC reader with its own light show. He hooked it up to a Raspberry Pi and developed a Python application to play music when LEGO Dimension Minifigures are placed on the toy pad. So, if an Elvis minifigure is placed on the reader, you’ll hear Elvis’s music.
The Raspberry Pi is hooked up to the LEGO Dimensions toy pad, with Musicfig (Dennis’s name for his creation) playing tracks via Spotify over Bluetooth. The small screen behind the minifigures is displaying the Musicfig web application which, like the Spotify app, displays the album art for the track that’s currently playing.
No Spotify or LEGO? No problem!
Spotify playback is optional, as you can use your own MP3 music file collection instead. You also don’t have to use LEGO Minifigures: most NFC-enabled devices or tags can be used, including Disney Infinity, Nintendo Amiibo, and Skylander toy characters.
Dennis thought Musicfig could be a great marketable LEGO product for kids and grown-ups alike, and and he submitted it to the LEGO Ideas website. Unfortunately, he had tinkered a little too much (we approve) and it wasn’t accepted, due to rules that don’t allow non-LEGO parts or customisations.
Want to build one?
The LEGO Dimensions toy pad was discontinued in 2017, but Dennis has seen some sets on sale at a few department stores, and even more cheaply on second-hand market sites like Bricklink. We’ve spotted them on eBay and Amazon too. Dennis also advises that the toy pad often sells for less than a dedicated NFC reader.
Watch Dennis’s seven-year-old son Benny show you how it all works, from Elvis through to Prodigy via Daft Punk and Queen.
There are some really simple step-by-step instructions for a quick install here, as well as a larger gallery of Musicfig rigs. And Dennis hosts a more detailed walkthrough of the project, plus code examples, here.
