Build a fully working Extreme Kits Lightning detector capable of detecting lightning from up to 10 miles away, giving an audible and visual alarm. The visual alarm has a flash and a storm LED and an acrylic edge lit display, which gives both an instantiations lightning indication, and an indication that lightning has occurred in the last few minutes. This lightning detector kit will also pick up other sources of electrical discharge, like a piezo or electronic gas lighter, and old car ignition, and electrostatic discharge or sparks. Because of this, it can be used as a demonstration of early spark based radio transmitters. The lightning detector kit is made using through hole components and so is an easy kit to solder and comes complete with an acrylic base and etched edge lit display. It also features a 400mm telescopic ariel for enhanced reception. The kit is powered from 3 AAA cells (provided) and can work for than 6 months running in standby so can be sat monitoring for lightning 24/7.
