I have just completed building the ROV version 2.6
I was able to get the tether to connect once.
I uploaded the firmware to Arduino as instructed.
After that I was never able to connect through the tether wires.
On the topside ROV board only the left and right LEDs shine,
the middle one does not turn on.
I was able to launch the cockpit if I connect directly to the BBB.
I decided to switch the two homeplug boards, and try the tether connection again.
I took the one from under the BBB and connected it to the ROV top board and vice versa.
Then I noticed that the Broadcom (bigger) chip on the topside homeplug
board's connectorless side is overheating. It quickly gets so hot that
I can't even touch it. I doubt that this is normal.
This doesn't seem right.
Have I done something wrong here?
