Great design, and nice way of doing the pin headers on the SSCs. I like that. looks a lot safer than how i've tried to solder on the ethernet pigtails.
For me...this is my first year, but keeping the etherdongle and FM transmitter inside, and then having 3 marine cases outside....will need to figure out the best place to hide them.....that will come in the next couple of weeks. but +1 for marine cases outside for me. I will avoid sticking them in a garbage bag as I hear moisture build up could happen
