I'm looking to build a very simple NTP clock, nothing else. I'd like to get a small screen and mount a small chassis to the back of it. It's sole purpose will be to display a clock and poll the data from our in house NTP server.
The reason for this is that we stream video live to multiple sites around our city and we need to show our operators when to start a count down and show our speakers when to start speaking. We find that standard clocks are unreliable and are looking for an extremely accurate solution without breaking the bank.
Basically I'm trying to get the absolute smallest form factor possible with a CPU capable of polling an NTP server... IE: next to ZERO horsepower.
