April Fools at School

So, I found out that my school doesn't use a standard clock system - instead we have this high-tech radio synced system, and every single clock has an antenna on its back. I was thinking of having some serious fun tomorrow, but that would require me stealing a clock to take home with me - dismantling it, and reverse-engineering it. I'm sure it wouldn't be too hard, but I don't know if I could have done it in one night..... That would have made an awesome April fools joke! There's so much potential! I'll probably end up wearing a Jester hat and my LED t-shirt, though. So much for that fun (perhaps as a senior prank?)

Last year our seniors played the radio through the PA system. They found the frequency of the system and used the FM transmitter to transmit a rock station all day.

Just move the hands!
On every clock in the school? Not very efficient XP
But then they all would be slightly different
Aha! Psychology.

How about submitting a paper on Electricity over IP....I have a thread started where you can get the info from :-)

I don't know if that'd be a great joke, especially since I'm not and never have taken any electronics courses in my school. Odd, right?

Every time I tried to sign up for one, there was a conflict with a major subject, and I gave up last year because I ended up teaching myself more than what the classes offered teach. Sigh.... silly high school.....

I'll print out a version of the article and give it to my physics c teacher, though. Lets see what she thinks about it =P

I think this link has all the info you need:


Essentially, clocks like these are tuned to an atomic clock signal broadcast by a central radio station in Colorado. In principle, all you'd need is a strong 60kHz radio transmitter, and some knowledge of the WWVB time code format.

Word of caution: I could imagine that there may be some hospital equipment etc. tuned in to the same clock signal. Broadcasting a fake signal over a wide area may very well have unintended consequences. It might also attract the attention of the FCC. So - use common sense!

I've already dabbled in WWVB - for use in my auto-setting braille digital clock. I'm not sure if it is WWVB synced, though. I can check tomorrow!

ON april fools yesterday i reset every clock at school so when the school started the time would show it had just ended!
