i need to come up with a way to transmit a signal from one device(personal alarm) to another. this signal needs to be activated when an alarm is triggared. when it is sent to the 2nd device this signal then needs to trigger another alarm to let others no of an attack.... ne ideas for a simple circuit would be great.

also does anyone no anything about tracking devices??? was thinking about making my life complicated :D

u can try and use bluetooth tecchnology for short distance wireless communication and write code to trigger the next alarm ussing an embedded processor. however the distance betw an two devices would be crucial in that case.

ive only got a £50 budget to come up with the proto type..... :oops:
the distance doesnt have to be massive for the prototype as long as i can show that it will work in thoery over a long distance.
the possiable tracking device will hopefully also work on this principle..



ne more ideas i would be extremely greatful :D
