Office Alarm

if u had or have a sister u will understand this.it uses a portable radio as a alarm.

ok all u need is a radio like mine or similar
wire stripper and or wire cutter
wire like the one from a telephone line
switch like mine
solder and glue from a glue gun

ok now open that radio and find the cords coming from the battery compartment and cut and strip both ends now solder an extra foot on both ends oft he two wires then glue the soldered part to the frame of the radio. make two holes and run the wires out.now u should have two non connected chords. connect them to the switch like in the picture.i used a Popsicle stick to keep my switch closed on my keyboard side on my desk.

ok now i attached it and put it on the most annoying and loudest channel on the radio. and if your radio has a headphone jack connect it to your computer speakers.have fun .Dont forget to comment,and you can use the same concept on the test button of a firealarm.Dont forget it has radiation though.
