I was so excited, love this kit, worked beautifully last night!
This morning I unplugged it to take it to work, and now when I plug it in, nothing.
The fuse is very hot, I get no beep on plug in, and the voltages I get off the test points are:
on the first pin of the 7805 (bottom of the board) instead of between 7 and 13 volts, i get 4.7
on the third pin of the 7805, instead of between 4.7 and 5.2 I get 4 descending quickly to 3.6
4.3 off the diode you have us test with by the chip.
any help? This thing was beauty for 12 hours, I want it to live again!
thanks!

Nothing obvious. Take a look at this post:

This one also worked and then stopped. Turns out the VFD drive chip went south. Pull the chip and see if you get a beep at boot.

Re: Ice tube clock help! Worked last night, unplug and no work.
However, on a whim from this thread - http://forums.adafruit.com/viewtopic.php?f=41&t=12765
I pulled the coin battery, and beep, lightup, fixed.
So, Ada, or anyone,, how would having the battery in the slot cause my problem? And why would it crop up after 12 hours of functioning use?
And now how do I provide power to the clock in case it loses power from the wall?
help!
Edit: I hesitantly slid the coin cell back into place, while it's plugged in and ticking, and it is still working,, will see if I can repeat the lockup on unplugging.
But I wanted to reiterate, this is an absolutely beautiful clock kit. Thank you for making it!

Re: Ice tube clock help! Worked last night, unplug and no work.
it sounds like something odd happened with the low-power detection circuitry. not sure what, its a total (*@#& to debug. we'll look for stuff that could be a problem, but we haven't run across this problem here yet :/
