210 LED lamp

Posted: August 24th, 2009, 12:00pm MDT by Jakob Griffith

Current fluorescent lamps are great for lighting large areas using very few Watts; however, LEDs are far more efficient at producing light and have less of an impact upon the environment considering there is no mercury within them. [Andrew] sent in his team’s LED florescent bulb. The first revision utilized 87 LEDs, but to increase [...]

Posted: August 24th, 2009, 11:00am MDT by Matt Schultz

Routers aren’t just for routing network traffic any more. With the help of alternative operating systems such as DD-WRT, Tomato, and OpenWrt, routers are now extremely customizable and can be utilized to suit a number of needs.

Swedish hacker [Hans Andersson] is no stranger to puzzle-solving robots. His prior work, A Rubik’s cube-solving robot called Tilted Twister, made waves through the internet last year. [Hans’] latest project only has to work in two dimensions, but is no less clever. This new robot, built around the LEGO Mindstorms NXT system, “reads” a printed sudoku page, solves [...]
Humanoid Robot + Homebrew Waldo = Big Smiles

Posted: August 24th, 2009, 7:47am MDT by Phil Burgess

Robot enthusiast [Vitalijus Rodnovas] built this rig to allow a humanoid robot to mimic his own body movements in real time. [Rodonovas] refers to his man-machine interface as a “master-slave suit,” but elsewhere this is often called a waldo after a prescient 1942 [Robert Heinlein] novella. This project page is slight on details and is mostly written [...]
