Yes, my hypothetical wasn't taken so well. I may set up a simple audio alarm with an analog circuit if I ever feel like it, but of course a rigged gun is stupid

Yes, my hypothetical wasn't taken so well. I may set up a simple audio alarm with an analog circuit if I ever feel like it, but of course a rigged gun is stupid. (I'd end up making it disabled via remote control too but then I'd worry about it not actually being disabled as I'm opening the door, even if it makes a disabled noise...) I should have stuck with the Microwave example below, that's cooler anyway.
