Since this is a clock, we have distinct advantages when it comes to sensing movement or vibration. We can assume the clock will be in a standard position (that being, upright, with the L.E.D. viewable by a human). Therefore we can dispense with nearly all electronics and install a simple two-wire movement/vibration switch. See here for excellent switches to do just that. It would take about ten minutes to do, including disassembly, soldering, and re-assembly.

For example, a mercury switch might prove to be too insensitive to measure the small vibrations of someone banging on the table, or it might be so sensitive that it activates simply from the vibration of the alarm clock

I just thought of linking to make although I do realize that in my choice of words it seems as if I am bitchin.
I didn’t mean sound like an asshole – I like this blog and I do appreciate the read;)

However, hardware hacking isn’t always practical, so I say go right ahead and make an alarm clock more accurate than NASA says… I don’t plan on doing this, but still cool.

It wouldn’t be accurate to within .0001 of an accelertaion unit, but then again we’re going to be smashing this thing more than once a day.

And there are those of us out here who HAVEN’T seen it elsewhere. For crying out loud – the poor writers of this Blog can’t seem to get ahead here…

Interesting hack – slightly surprised they left the sensitivity Pot inside the case completely. Sure it looks like they didn’t tamper with it any – but I can imagine situations where one would need to adjust the sensitivity to match the environment – opening it up to get at this seems a bit over the top, when they could’ve cut a hole in the case and made it externally accessible.
