An LED cube kit for the Raspberry Pi

A place to share some of the details about the electronics, and hardware development stories behind the LumiCube, which we recently launched on Kickstarter:

My friend Sean and I spent the last year creating an interactive LED cube kit for the Raspberry Pi. It is covered in 192 individually programmable LEDs and packed with electronics, from a microphone and speaker, to a hand gesture sensor and orientation sensor. We also created a simple web-based interface so people can easily run their own Python scripts on it, or just choose from the built-in applications we include by default. We launched it last month on Kickstarter, and it’s been just amazing how many people have backed us!

We've already shared a behind-the-scenes look at some of the hardware and software we created for the prototype LumiCube, over on

Over the next few months we will be refining some of the electronics and enclosure design, before kicking off our mass manufacturing run. We thought it would be nice to share some of that story over here at, where we can go into a bit more detail than will fit in our updates on Kickstarter.

As always we are keen to hear from the community. If anyone out there has comments or thoughts on what we are doing, please do get in touch!

  • Snap fit design for injection moulding

    We have been investigating getting the LED panels injection moulded (soft tooling as this is much quicker). This allows us to make a much more precise part that fits the case better and will make the kit very easy to assemble.

    Some of this week was spent trying out various designs, to allow the panels to snap together. The ultimate rigidity of the cube will likely always rely on a few screws, but these snap fittings should make assembly (by the user) much easier. Above is pictured an idea for a right-angle fixture between adjoining panels. The idea is that the curvature is gentle enough for an injection moulding bumpoff, but still deep enough to hold the panels firmly during assembly.
