Lego Servo Multiplexer
A NXT brick can control only three servos, but don’t let that limit you. This multiplexer — dating back to 2007, an oldie! — uses two servos to do the work of twelve, thanks to this clever homebrewed multiplexer.

Michael Krumpus’ Hackvision gaming pad just got sweeter: I implemented Asteroids for Hackvision, written completely using Arduino technology. The ATmega328 is more than powerful enough for real arcade action! You can follow that link to buy a Hackvision or to download the Arduino code for the game.

Martijn “Dino_Martino” Hellemans of the NXT STEP Mindstorms blog has been working on a motorized Lego tank that packs a lot of sophistication. For instance, he uses a MTRMX-Nx multiplexer to control both NXT servos and Technic motors. In addition to rolling around on tank treads, the tank also packs a Badass Lego Guns-style “high […]
Built mostly from Lego Technic elements by Brickshelf user barman, who credits the idea to a model displayed at Brickfest 2006 by one Jason Allermann. Looks like it can’t really expand that far. Still cool, though.
Todd Wilder’s mystery box has eight hidden compartments, which must be opened in a specific order. The ideas for this box came to me a little bit at a time, after my 22-year-old nephew had seen my other boxes on MOCpages and asked me to make a box for him. He wanted me to make […]
