Simple Lightning Detector Circuit Diagram
This is the Simple Lightning Detector Circuit Diagram. Built to make the wiring easy to follow. Read the text below! This new lightning detector circuit uses a single inductor tuned circuit to receive static pulses from lightning at a frequency near 200 kHz. The need for a tapped tuned circuit is eliminated by employing a very high input impedance RF amplifier, using a darlington transistor. The amplifier is micro-power, and the whole circuit draws only about 200 uA from two alkaline D cells, hardly denting the shelf life. The flasher portion of the circuit is similar to the earlier versions, only the polarity of the transistors is reversed. As a result, the output pulses momentarily go to ground from a normally-high state. The schematic and close-up photos were made with the beginner in mind. Questions about the schematic can be answered by close-up examination of the photos. Try a magnifier utility for an even closer look. The 150k resistor in the base of the 2N4401 may be replaced w...
