At it’s core is the main speaker - everything is contained in this box including the Lithium Ion batteries, recharging circuit, bluetooth receiver and amp. You'll also find both a standard USB and USB C port to recharge your other devices.

This is where it gets cool though: Assemble the second 'slave' speaker for a louder system and it’s connected as simply as sitting it on-top. Magnets hold it in place and the Pogo pins form the electrical connection.

Why did I design it like this? We’ll you can face the second speaker in the same direction for increased volume, face it sideways for a wider sound stage or back to front for when it’s in the middle of a group.

This also let’s you choose which modules you take with you when you head out from home.

And when it gets later in the evening why not add the funky disco light module on top to light up the evening whilst you listen to tunes? :)

This one is themed after everyone’s favourite plumbers. Don’t worry though, I’ve included an alternative dialled down design should you not care for Italian servicemen. 

In the video at the top I’ll explain in detail everything you need to build your own speaker and as a bonus - towards the end of the video I’ll show you how to add the disco light pipe.
