The MHE-Cube

The cube MHE-Cube was my first LED art project.

The cube MHE-Cube was my first LED art project. It was a gift from a number of employees at Statistics Austria to new founded company MHE & Partner. The cube form was chosen because that company was working with "OLAP Cubes" which is a form of representing data in a three-dimensional table (sort of...).

The cube itself was built by Helmut Stenitzer und Eva Fischer. The electronics inside by me (Simon).

Once plugged in, the microcontroller on the board lights the LEDs in various patterns. Also, a 1 GB USB-Stick is included which can be accessed by the PC connected to it. This way the cube can actually store data ;)

The light effects software is available here: avrlighteffects.tar.gz (README included). It works on an AVR microcontroller as small as the ATTiny26 and it's controlled by a simple scripting language. Light effects for up to 8 channels can be designed and previewed on the PC and then flashed onto the microcontroller.

Here's a video of the finished cube:

And here you can see the opened board:
