While the NXT may be the reigning champion of the LEGO robotics world, there's actually another hobby platform that's caught in on the broader maker/robotics/hacker community. That's the arduino board. Although the arduino is completely open (and open source), different "shields" can be added to quickly add new features to the base microcontroller. In this case, a wave shield was used to allow this TARDIS to play the Doctor Who theme at regular intervals. The TARDIS (which stands for Time And Relative Dimensions In Space) is the Doctor's famous vehicle that is bigger on the inside (and has a few other interesting features - the Wikipedia article on the topic is terrifyingly large). This was a huge hit at this year's BrickFair, where Jon also led a seminar to fill us in on the possibilities of using the arduino platform in LEGO models.
Details: This gorgeous microscale spaceship shows part of why microscale building is so appealing - get a load of the bizarre uses for common parts in here! I see a wrench being used as a weapon, two rows of minifig chairs making the outer hull of the craft, hinge parts used as decoration parts on the outside, TECHNIC parts used as weaponry, a few 2x2 turntable bottoms and tons of the newer small slopes. I'm pretty sure that the side craft is using a few obnoxious LEGO® RACERS parts to great effect, and that's before we get into both the side craft and the main cruiser using various wheels and gears as jet engines. I might be seeing a sticker or two here, but that's barely noteworthy next to all the other cool tricks here. In this shot you can even see a Wild West set's log-brick and even a few skid plates used as siding!
