So when I was looking through the scrap dumpster, I found a boardset with a big LCD on it and two wires sticking out the back. Didn't have a clue what it was, but reverse-engineered (not really) the board to find that the two wires were, hard to believe, hot and neutral for AC feed. Strange. Never seen anything that low-consumption take such a high input.
There's reason to the rhyme, though. Without isolation from the AC line, you can inject an RF signal back into the waveform.
I figured I'd bite the bullet and plug it in. I tested the connection to find that there was no short to speak of and the resistance was actually around 8 megaohms, telling me that there's a multi-stage powerup process. With a standard figure-8 cord as my socket, I put some distance between myself and the board and plugged it.
Nothing.
That is, until the display lit up and showed "Initializing..."
Once started, it showed eight choices, one for each button. I clicked the button below Info and got the details on what the device was. It turns out I had in my possession the internals for a home command center that normally goes for about $300. Only this one has some defect I don't know about yet.
Regardless, it has a 240x120 pixel LCD display with a nice white backlight.

Derek, Can you post a photo of the board? or email me a photo?
I can likely tell you what it is.
