I love it, can't wait to see the display wrapped up. How will you power up the relay board? Are you going to run power from the main power bar? If so you need 3 pin din instead, 2 for 5v and one for ground. The relay board has 2 power inputs so it can be isolated, on the power bar board I have two 5v regulators, you want to power the relay board from both of them so its isolated. You can power the relay board with a separate power supply which would isolated it but you still need a common ground going to it.
