GBC actuality

Nice work in progress:




And cute GBC display in Mondsee 2011 at Austria:

Parda's LEGO TECHNIC pneumatic compressor V4

This is my 4th Lego Technic compressor, after little modifications it has been used in a pneumatic sequential GBC module that I will present soon. Very simple yet effective.

BallMageddon

 "BallMageddon is an all LEGO scrolling sign that uses 2-inch diameter DUPLO balls as its display element. Seven builders, 11 NXTs, over 800 DUPLO balls, and many 1000's of LEGO elements.  

 Each character took a bit over 3 minutes to display. This was shown at BrickCon 2011, at the Seattle Center on October 1-2.

BTW: The final "BrickCon 2011" segment took approximately 45 minutes for the contraption to display in real time."
