Details: Remember the Pinball Machine we featured back in 2007? Someone inspired by that model has now created a Mindstorms NXT version. This one is also purist - all LEGO except for the ball (I suspect they could have used a LEGO ball too). Only 6 NXT bricks were used, compared to 13 RCX bricks in the original. A substantial amount of instructions are up at the site above, including source code (you know, for all of us with 6 spare NXT programmable bricks and over 8000 spare LEGO pieces to turn into a pinball machine).
Details: This is a stunner that you have to see to believe - a complete pinball machine, in full size. There are a ton of great photos here too. You can see the underside, where dozens (hundreds?) of beams form a sturdy base for the model. There's also a clever mutiple RCX holster to allow the intelligent bricks to communicate with each other. Some slight cheating was involved for the number displays, which are made with paper glued to miswritten CD-Rs, but otherwise this is done entirely with LEGO® parts - lights, motors, sensors, and all. Of course, even beyond the awesome scope of this project and the robotics-related challenges, this has some great detail work. The lettering, the rows of windows, and the obstacles all look amazing too.
