I ordered two PoE clocks, one with the 12 hour face, one with the 24 hour face. Earlier this week I considered using the Vetenari Clock project circuit board to control a cheap analog clock movement and have it do my bididng -however I can't write the code in $99 of my free time!
Note that the clock in the Vetenari kit is just a cheap quartz clock like you could get anywhere, and the replacement board it comes with isn't of any use if you're trying to do something different. Basic quartz clocks are not a good choice for hacking into a precision display because they can only tick forward in one second increments, with no way to know what time is being displayed nor a reasonable way to adjust forward or backward an hour for daylight time changes. In other words, you can make it tick precisely but you can't really set it.
I'm sort of interested in getting an analog WWVB type clock and seeing how much work it would be to coopt *that* hardware since it is designed to set arbitrary times, but I have a feeling I'd be better served making my own mechanics with a stepper motor and reduction gear. Of course a digital clock would be much less complicated, which is what Miguel was asking about to begin with, but that's not nearly as much fun.
