James,
A close-up of our electrical layout can be found here:

Our mast has an axis camera, ring lights, and an ultrasonic sensor in it. They are enclosed in a custom 1/4" polycarb integrated housing designed, CADed and built by one of our grade 10 students.
The video was produced and edited by one of our grade 9 students. I think he did a masterful job given the seemingly random raw practice footage he had to work with.
