140 db alarm clock hack
Saturday, September 26, 2009
This silly little video caught our attention. It is an alarm clock, hacked with two amazingly loud car horns. They are using a laptop power brick to push the two external car horns. The horns are triggered by a relay wired to the internal speaker of the alarm clock. This is a super quick project that could be done, not only to help yourself, but it is the perfect amount of effort for a prank. We bet you guys could probably wire one of these up and hide the horns in only a few minutes. If you are having problems waking up, you might also want to check out some of the other alarm hacks we’ve seen.
