LED Pixel Cube

An LED pixel cube is a plastic container with an LED, battery and magnet on one end a translucent square of paper on the other. The magnet lets it stick to metal surfaces and the effect from a distance is that of a glowing square. Make a lot of these and you can start to draw an image. Make a ton of them and you'll even have a massive glowing QR code.

Really, we did this.

What I need to know is, can a tiny wireless switch be made to turn this on or off. I am making a terminator appliance and need to be able to turn it on or off. It needs to be tiny to also fit under the appliance..

Wow that is neat! Reminds me of those LED Throwies... but with more of an artistic bent! Also love that the QR code actually worked!

...Woooow.

How many people did you have working on the QR image and about how long did it take? It looks spectacular. The video covers just a little about the project, just a little about making and a little about Instructables, it's brilliant!

About a dozen people for two hours or so. Hard to say as the crew kept changing in size.

What type of case did you use? I'm thinking of making a 3D projector with this.

It's from the container store.

That's a good idea. my son is into star wars and I wonder how we can adapt this to make an r2d2.
