Abstract
A blasting cap simulator for use in bomb disposal training. The simulator has a bridge rectifier, a voltage regulator and an RF key fob transmitter. A fuse across the incoming power lines shorts the device and prevents it from activating until the fuse is blown. It then sends an RF signal to an instructor. The transmitter uses the power lines as an antenna to send out the RF signal. The transmitter is protected from the voltage of the power lines by a choke located on each powerline.
