This does suck in a lot of ways. I like how they say it will be a lot harder to control not with things like wind and solar. I don't see why, I suspect most of these will end up going to or starting out as DC then being converted to 60HZ. If they could do this with massive turbines and physica

The mains "frequency", at least here in the U.S. is always being corrected for small variances that occur in the frequency during the day. Therefore the overall error is none over a years time. Clocks are therefore always accurate and never need resetting, unless of course there is a power fa

I wonder if an adaptation of my GPS time system mught work. I have a central clock that reads the GPS and then sends it to the other clocks via RF. What about a central clock that sends out a 60/50 hZ beat via RF? RF receivers are fairly cheap, and then you only have to calibrate one xtal or wha

Are the RF receivers cheaper than the GPS receivers at this point? Sparkfun sells some pretty small GPS receivers for about $25.. Course, if you're into WWVB, digikey has a WWVB receiver & antenna for $10.. although for my clock, I needed to replace the original tuned loop antenna with a larger

Very good price, but that isn't a GPS/WWVB. I guess you could attach that to another and connect to a WWVB/GPS for remote location of the receivers instead of a long antenna wire. Maybe have it connected to your garage door so the clock can open/close the door depending on the time of day.

Make sure to buy the 315mhz version instead of the 433mhz.. 433mhz is smack in the middle of the 70cm band and is used for linking repeaters. Also, unless you're a licensed amateur, transmitting on 433mhz is limited to part 15.231 which authorizes "Intermittent Control Signals and/or Periodic T
