Well it's intended to be real. I am going to check out premade boards before I commit to FR-4. I've got the first pass of the layout done. It needs some tweaking and experimentation, but I see no show stoppers.
The WWVB clock has a 6 volt VCC. The entire sensor board will run at six volts, which also happens to be the upper VCC range for the AMN11111 sensor. So the circuit design becomes fairly trivial. Power & ground in, triac output wired in series with the clock transformer secondaries. I'm not a "must make" guy so if someone can point me to something off- the-shelf that can do the job, I'll bite.
