Step 1: Parts
1 altoids tin
1 switch of some sort
1 "d" battery with holder (radioshack)
half a popcicle stick
clear fish wire
match stick or any non metal thin stick
Step 2: Cutting
Cut a rectangle big enough for the D battery holder and two smaller one on the side for the buzzer and the switch.
Step 3: Wireing
Connect the buzzer to the switch and connect that to the battery holder Do not connect the wires from the buzzer to the battery holder
If your good with a solder then I recommend that

Have the two remaining wires stick out. see pic.
Step 5: Buzzer Base
tape one wire to the side of the altiods tin and tape the foil on top. see pic.
Step 6: Tripwire Activator
tape other wire to popcicle stick and tape the foil to it( the wire must touch the foil)
