More conversion of LEGO into Arduino-controlled LEGO
Next in kenyer's series on modifying LEGO bricks to work with Arduino is his double-LED brick. As always he has described in great detail how to modify bricks in order to add LEDs, making them flush and with their own customised electrical contacts. His methods do involve the use of a CNC machine, however this could be done by hand if you weren't in a hurry. Here's a quick demonstration of the twin-LED brick:
Once again very well done, and we're looking forward to see what he comes up with next. In the meanwhile, follow his series here. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're looking to make more creative designs with LEDs, consider the Freetronics RGBLED: full colour 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.
