Re: [time-nuts] NTP Clock suggestions?

Hi Chuck: The Western Union Self Winding Clock Co. clocks that were used in radio stations had second hands, unlike the prior clocks that were used in banks, railroad stations, etc. that only had hour and minute hands. See figures 4 and 6 at the top of the page: http://www.prc68.com/I/SWCC2.sh

In another thread that was active today, the Symmetricom NTP clocks were mentioned. I bought two today for $99 a pop, both power over ethernet models, but they have a line powered model too. One 12 hour face and one 24 hour face. On Wed, May 29, 2013 at 12:13 PM, Eric Williams wrote: > Inova

OK, the LOWEST cost option I can think of for driving an analog clock with millisecond accuracy. Buy a normal AC powered clock that uses a synchronous AC motor that runs off the 60Hz AC power, not a battery powered clock. Then have your NTP disciplined computer generate a 60Hz audio sine wave.

Re: [time-nuts] NTP Clock suggestions?

Hi SNTP probably is ok if you are running against an NTP server hardwired on a local LAN. Running it through a home modem and out onto the internet likely isn't going to be as good as a full blown NTP stack. You could quite easily get enough lag / delay to get into the ~ 100 to 200 ms region th

One more idea: Buy one of those "Atomic Clocks" that run off WWVB. Then use time code to modulate a very low power 60KHz radio transmitter. The clocks will pick up your signal and sync to it.The clocks run on battery power and you don't need wires. But then I did notice you can buy exactly

Re: [time-nuts] NTP Clock suggestions?

Hi If you go with the Pi's I2C port, it's strictly a 3.3 volt port. Some (but not all) of the display boards are 5V gizmos. If you go with a WiFi approach, be careful about latency. NTP only understands symmetric delays. Of course if you are on a cable modem there's noting in the WiFi that's

Hi If you are doing this from scratch today, would you go IRIG or would you go RS-485 for a wall clock? Both will drive more cable than you are likely to have in a house. Both are reasonably noise immune. With RS-485 there's less to do. It's a serial stream like any other bunch of "stuff" into

I've seen LLCD computer monitors used as clocks. Seems this would be the perfect use for a Rasbury Pi. and a cheap monitor. $100 or maybe a low-end Android tablet. The way it is more commonly done is you have you computer that is using NTP produce an IRIG time code. Then there are any number of
