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.

Hello Everyone,
I thought some of you might be interested in the following. A few months ago, a
few time-nuts discussed what they had done to convert existing equipment to a
large GPS clock. I elected to design my own clock display instead. Mine is fed
by a Garmin GPS-35 GPS and it uses a 64 x 8 LED array for the display. It is
driven by a PIC18F1220 with custom firmware.
Cheers,
Bert, VE2ZAZ
