hi
you'll have to forgive my ignorance here but it has been a long time since i
did my gcse in electronics nearly 20 years in fact so i've forgoten alot of
it, but i have a question.
i've had in my work place a large number of computers inside of wooden
cages, unfortunatly these boxes are poorly constructed and it has become
apparent that with some shaking of the door the locks pop out of their
sockets. this has lead to a few people trying to steal the pc's.
what i'd like to do is make a key armed alarm set-up with a led to show its
armed, and a microswitch to put on the door to set it off when the doors
open.
like i said it has been a very long time since i did this last, and although
i can still do the basics like solder, i really havn't cant remember much on
the design.
can anyone advise what i should get and how to construct it, i would prefer
to remeber and construct it myself but unfortunatly i have to get this
fitted sooner rather than later.
many thanks in advance
