Project 4 'Intruder Sentinel'
03.12.09
Tired of always being snuck up upon? Doing any
stealth surveillance or reconnaissance? Or maybe you just need to set-up a
fail-safe alarm for your stuff so your little brother doesn't go into your room.
Taken from the design by Brad Graham
in 101 Spy Gadgets for the Evil Genius, this circuit
will allow you to not
only trip someone but also have it set off an alarm when tripped.
Its a fairly easy circuit to build and is
incredibly straightforward. You shouldn't have any problems with this circuit at
all, but if you do we're here to help.
