So, I've dabbled with electronics every now and then, and am pretty comfortable getting little bits and stuff from either Radio Shack or Fry's to build things.
Here's what I need. I've got a really long driveway, and just picked up a little driveway reporter thingy that will sound a buzzer in the house when something crosses the path of the beam about 200' away.
Unfortunately, the buzzer is a little quiet, and I'd like to have something a little louder/interesting.
This gizmo has a relay on it you can use to trigger other things, and it's capable of 120 volts and 10amps.
Does anybody have any interesting suggestions for either a DIY circuit or something more interesting than the normal doorbell?
Thanks!
