Description: I seem to have always wanted to make one of these. Some of my earliest designs were of something like this. One time I was in Radioshack and saw a very cheap alarm. I bought it along with a case and a nice switch. When I got home I cut the alarm open, stole it's guts, and grafted it into the case. I had to drill holes to make the noise as loud as possible, but it still wasn't as loud as it could be. The circuit and switch were very temperamental, leading to several instances where the alarm set itself of on my desk in the dead of night. I decided it wasn't worth keeping around so I cut the power wires and threw it in my junk pile.
