How freakin’ cool is this? A European LEGO hacker, Claude Rieth, has created an electronics experimentation lab out of LEGO bricks with discrete electronics components (resistors, LEDS, transistors, diodes, IC sockets) built into the blocks. To build a circuit, you just press down the blocks you need, wire ’em n’ fire ’em. Cool. In LEGO hobby parlance, someone who hacks the blocks to add unofficial functionality is called a Grinder. This guy’s the king of grinders.
