pic: Wiring gone smokin'

This happened today at the Brazilian Invitational at Globaltech.
This is the SIGNAL wiring to the camera (connects to the TTL board) and couldn’t possibly be in contact with +12V. Current limited +5V wouldn’t do that either.
It’s a mystery, it generated a lot of smoke (wires also need smoke to work, it seems) and the crowd loved it.
Thankfully the team “fire training” worked like a charm and nothing was damaged (apparently… heh)
