This is the current inside of the brain. One of our benefactors gave us this Pelican knock-off to use last year, and it's great. Easy to open and close, totally water-tight, and the foam makes it easy to stick everything in.

The main board is of course front and center, and you can see the GP and the IMU on top of it. The Beaglebone Black is under the board, sticking out on the right. 

The little black box on the right is the RC receiver, and the little black box on the left is the AIS receiver. The AIS antenna will eventually be mounted higher, when we find the right nut for the bulkhead BNC. In the meantime, the antenna and cabling is just taking up space inside the box.
