Chris,

Well, actually, I just took a chunk of ceasium, put it in a coffee can =
and got one of those GI radiation counters. The only real problem is the =
glow at night in my bedroom...

The Atomic Clock module is a WWVB receiver/decoder. It also has an =
onboard time source which is corrected as often as the WWVB signal is =
recieved. It outputs in packed hex which is convienent and small. Sorry =
if the word "module" threw you off.

The one I used is no longer in production. The company makes another one =
for around $160 bucks called the 325B. I have the 321B. If you go to the =
website the product isn't listed there because of legal hassels they are =
having with someone re-marking and selling it. Anyway, he said if folks =
wrote and mentioned me he would still sell them.

The company : http://www.ulio.com/
Email: rod@........

I had a shot at hacking an Oregon Scientific and a Klockit atomic clock =
movements. The signal reception for both was poor. (I live in "black =
hole" for RF) I got the corrected PPS out of them easily, but date, =
pending leap second, leap year and so on was beyond me, partially due to =
signal strength (clockit) and partly due to my (lack of) ability =
(O.scientific), so I'm sure a smarter monkey could make it work.

BTW, I guess my messages are showing up, although I never see them. I do =
get the confirmation post. This happen to anyone else?

        What are atomic clock modules, please and do you have a source? =
