A bit late to the party, but here's a pole cam in Week 3 w/ the new height restriction.

WARNING: TURN DOWN YOUR VOLUME.
Apologies on the volume level, it was recorded on a school laptop from a webcam on the pole, and we didn't have any "good" recording software to use, and I haven't had time to edit it to clean up the audio.
As for the pole itself - we had really good luck with a simple paint-extension pole from Home Depot I had laying around... and a lot of duct tape. We screwed to our driver station board (velcro backed) a stack of wood... a 2x4, some 3/4" spacers, and another 2x4. "just-fitting" holes were drilled into the 2x4s to sit the base of the pole in. With the spacers the stack was tall enough to securely hold the pole, and the refs didn't even take a second glance at it.
