What about using either any clock and feeding it with 50Hz divided down from
10Mhz or using an MM5311 ic clock and feeding it with 50Hz. Thats what I
use.

Hi Max:
By using a PIC you can do much more than just tell time, for example
display the Day of the Week and because the calendar is good back to
1800 something you can set the clock back that far and know the DOW.
The next step was going to be to install a table of leap seconds so

Atmel chip and drivers should be able to do it.
Maybe include date and holdover and phase of the
moon for good measure.
Has anyone studied the Hampton Court Clock?
Now there's a clock! Would make a

We have these kinds of clocks all over our lab. Typically they run
on IRIG. But if you are only showing seconds the 60Hz wall frequency
is more than good enough and they sell 6 digital clocks at Wallmart.
An easy clock might be an way-old notebook PC. Even one that uses a
486 processor or an
Please add my me-too to this discussion.
I would like to see a clock that simply tells time, reminiscent of the ones I
put together in the 1970s, but with LED displays
large enough to read from across a darkened room. I would prefer 24-hour format
and I want a 6-digit display with seconds.
Why not just buy or scrounge a small microwave oven or VCR?

I think he wants a clock that will actually tell time, rather than one that
merely blinks *12:00...12:00...12:00...*

Hi
I suspect that something like:

would do the trick. No idea what they cost.

Hi
Found the GSA price list at:

Looks like you can get the basic no frills model for about $400 and they go
up from there.

If you are going to use a laptop... might as well go with the ever handy Lady

clock to full screen. Plus it can do sidereal time, etc. You can even select

I would avoid BRG clocks. I've used them in two different companies now
and they're pretty much junk in my opinion. Both of the clocks I used
had IRIG inputs and they only sort of work. They seem to randomly lose
IRIG lock every few days and will easily get 1/2 second off, even when
locked.
