Here is an attempt to show the wiring of each relay board. We have some 22-24 gauge wire coming off the low voltage side of the relays to go up to the controller. In the front of the relays we are jumping the hot (black) wire between all the relays to keep the wiring clean and simple. We will attach the unused terminal to each outlets hot wire.
Here you can get an idea of the wiring from a top down view. We connected the bottom board to the bottom half of all the outlets and the upper board to the upper outlets for consistency and ease of access incase of any required maintenance.
So here we are experimenting with layout for the controllers on the top level. You can see that our custom board for the vu meter, a breadboard and even the arguing all fit easily into the space remaining. In future projects we will do some control panel stuff with the extra space also.
So here we have a shot of the setup for first test. We used a 12v battery pack to power the vu meter board, though if I had a 110 to 12v dc power supply board I would much rather use that.
