Derek Anderson writes, "I wrote an article on CNC machining a custom high performance LEGO controller. Part 1 is online now, and I will be posting followups weekly." Derek's not just talking about any old LEGO controller. He's designed a Gumstix-based controller to replace the usual LEGO brick. He calls it a GumBrix. It's a pretty cool idea for anyone wanting a high-powered Linux based system for their LEGO creations.
