LEDs are nice. An array of LEDs is cool. A 2D LED surface looks awesome. A 3D matrix made of shiny blue LEDs is... (The end of the sentence is left as an exercise for the reader.)

What it does

We put together a cube made of LEDs. Our original goal was to build a game for the cube, but the result looks cool enough to be used as a decoration!

How we built it

We used 512 LEDs. After testing that all of them worked individually, we soldered them together in 8 layers of 8x8. Then we added 8 multiplexers and some resistors to a printed board that would hold the 8 layers together. After soldering the layers together, we finally got a cube that we can light up.

Challenges we ran into

Trying not to go crazy after 6 hours of soldering LEDs together.

Debugging electronic components, replacing a handful of burned diodes after they were in place.

Accomplishments that we're proud of

Getting the LEDs to actually have a (kind of) cubic shape, and seeing them turn on!

What we learned

Hardware is some serious business.

What's next for The UnparalleLED cube

We want to build a Snake game inside the cube. It was too much to do it in the weekend but that's something we want to do! Actually we would try to 'port' other games to the cube too, like a 2048-style game.
