Well, everything "seems" to be running fine in a test environment, but I have a concern. The red led on the RPI will flash on and off regularly, and goes off completely when the relay is engaged. I read somewhere that flashing means that the voltage is dropping, so I'd imagine that going out completely can't be good. What's strange is that it is working fine...

Also, I think I'm going to move to a solid-state relay. Checking into those now.

No headway at all on the "sexy" case for this project, so everything is just sitting out in the open right now.
