Step 4Now for a trigger!
The pictures below show a couple of the switches I used below to sound my alarm.
First one is the door switch (obtained from an unused security system in a wharehouse)pic1 shows door switch off pic2 shows it in the on position. -=p
Second is my Favorite it's a "REED" switch,Just wired one of those things up inside a DVD case & I used a magnet inside of an old newport box simple yet effective. -=]
When the 'Ewport' (not a typo) box was picked up the alarm would sound, It helps if you run long wires from the detector & hide it much funnier.
I made a stash box version of this alarm using the pressure sensitive switch out of an old phone hangup button I'll be posting it soon.
Well have fun with it as you may, just be careful these things contain RADIATION, So don't go putting it around young children or animals NOT COOL!
Feel free to ask me if you have a question about anything posted.
