Re: [time-nuts] My Custom GPS clock
Hello, Bert - Not having that much experience, I am wondering whether I could retrofit their DE-DP22811 http://www.sureelectronics.net/goods.php?id=1164 to make an 8 digits clock having 1/100s: 23 59 59 99 Based in NYC and ideally I would feed it UTC reference, either by GPS minus 15 seconds (as leap seconds are likely to be dropped) or any other source. I only need 1/100 s accuracy, might even drive from power line. I'd be glad to pay someone to implement. I have Paypal. The closest thing I found was a director's clock, yet frames from 0 to 24 instead of hundreds of seconds from 0 to 99.

Re: [time-nuts] My Custom GPS clock
A few years ago, I did a similar clock for use in the car, but using a 4 line lcd. I never thought about correcting it for the software delays- an excellent idea Bert, thanks. I guess I am going to have to do a bit of a re-write sometime soon. Thinking about it, I could just feed the 1pps into the pic and use that to trigger the display update but with one second added. If anyone is interested, the clock is here www.vk7krj.com/ham_stuff.htm and if anyone wants the source code (it's in crownhill pic basic) I'm happy to supply it.
