DIY Fire Alarm Clock

So you have trouble getting up in the morning – here’s something that might help nudge you out of bed. The DIY Fire Alarm Clock is a combination of a common alarm clock complete with some interface components as well as a fire alarm bell, where the alarm signal is hijacked from the clock circuit board and used as an input to the interface board. The result? An ear-clanging din that is guaranteed to wake up the entire neighborhood, where you’ll probably receive nasty stares from everyone the next time you get out of the house.
