Niceeeeeeeeee

Brandon and I would spend all day Saturday sometimes building with his legos, at one point we inherited two MINDSTORMS kits and took it all to a new level...

Building pulling tractors/crawlers was out thing, he learned about gear reductions / multipliers and pulley/belt reductions, sometimes as much as 100/1 ratio which worked great for making pulling trucks/tractors/cranes...

cam movements / pushrods...

Lego's are awesome... Keep him going Mateo...
