Now for something that leans towards synergy between mathematics, origami and electronics comes the following project by Abhik Pal. In this example he shows us how to make dodecahedrons from cardboard, that can then be illuminated with an Arduino-controlled RGB LED. This gives the opportunity to make a neat colourful announcer of various data or events - or just a neat glowing lamp or night light for children.
The enclosure may sound incredibly complex, but can be made quite simply with some cardboard, glue and by following Abhik's folding instructions. And the results can look very good, for example:
If you're looking to make your own projects that could use different light effects, consider one or more of the Freetronics RGBLED: module. It includes a bright RGB LED on the top of the board and a WS2801 constant-current, addressable, multi-channel LED driver on the back. This smart module can be daisy-chained, so you can connect a number of these together in a string and drive each of the module colours individually from your microcontroller.
