NXT-ified LEGO Crane

Loyal reader Justin Chan just sent through his conversion of the LEGO Technic 8421 model 2.  He's done an excellent job and by the looks of it has crammed a lot in such a tiny space.  It still has all the original functions of driving, steering, rotating / lifting/ extending the boom arm and even lowering the ground supports.

Looks likes he's got the Mindsensors Motor Mux to get all 6 motors to talk to the 1 NXT onboard.

The whole thing is controlled by another NXT connected via bluetooth.

All this from a secondary school student.  Well done Justin!
