Detect Lightning with a Simple Circuit

Nov 22, 2017The lightning detector is a "resonant tank circuit" which detects lightning electrical impulses, amplifies them so the noise can be heard on a speaker, lights an LED and moves the needle on the meter. A lightning simulator is used to test or demonstrate the unit in action when no storms are in the area. It is a low frequency, low level Get price

How Metal Detectors Work

A sampling circuit in the metal detector is set to monitor the length of the reflected pulse. By comparing it to the expected length, the circuit can determine if another magnetic field has caused the reflected pulse to take longer to decay. Treasure hunting - researching and trying to find caches of gold, silver or anything else rumored to Get price
