PICkit 1 Flash Starter Kit. Tinkerlog. Raspberry Pi with RGB-Pixels and node.js. This article is also available in Serbo-Croatian language by Vera Djuraskovic. Thanks Vera! For quite some time I had my Raspi lying around. And some RGB Pixels as well. So it was about time to bring them together. For the server part I decided to use node.js. The pixels are connected to the Raspi vi SPI. When put together, it works like this: The browser opens index.html and renders an array of 25 clickable batches.Clicking and dragging on a batch changes its color and lighting.These changes are send to the server over web sockets.The server receives the color changes, updates the pixels over SPI and then sends a broadcast via web sockets to all connected clients Over all I’m quite pleased with the outcome.

BEAM Robotics FAQ :: Solarbotics. What is this BEAM stuff anyways? Where did it come from? In 1989, Mark Tilden invented the techniques of BEAM Robotics which combines simple, robust electronics with clever mechanics (and frequently solar power) to produce capable, autonomous robots.
BEAM is an acronym Mr. Tilden built from the words Biology, Electronics, Aesthetics, and Mechanics. Biology We look to nature for inspiration, and see if there's a spin we can put on it that makes the inspiration work in a robot. Electronics This is about appropriate electronics. Aesthetics Not a word used often! Mechanics Clever mechanics can take care of huge design problems. The net result of this design philosophy is a robot-building technology that is often cheaper, more robust, and quicker to build than traditional methods.
