This is a cool clock. Gives me an idea though. When I have some spare time (yea right) I think it would be cool to make an alarm clock that activates a REAL 10" fire alarm bell!

"The Fire Alarm Clock is very loud. And the noise is pretty deafening too. Shame about the naff digital LCD display though, eh? Priced at $14.95 excluding the slidey downy pole.

There’s no ignoring this alarm! This fire bell-shaped alarm clock is LOUD! It has a digital LCD display and snooze feature. Use the buttons on top to set the time and alarm. Demo button lets you hear that loud alarm any time."

I have one that's pretty large, not sure if it's 10" but 6" or bigger.
It runs on 120VAC, with a solid state relay and some checking you could find the 'on' signal from the alarm clock and make a circuit that boosts that up to the voltage needed to turn on the relay which would activate the bell.

It's an interesting idea. Smile

With a 100 watt stereo amplifier on your computer is pretty effective as well.

I bet that would make a great room alarm to fend off the other people that live here.
