Lightning Detector Circuits
SMRTR summary
A simple DIY lightning detector circuit uses a single inductor to receive static pulses from lightning strikes at around 200 kHz. The low-power design uses a high-impedance RF amplifier with a darlington transistor, drawing only 200 μA from two D batteries. When lightning is detected, an LED or incandescent bulb flashes briefly. The detector works best outdoors or near windows and can be built by hobbyists using basic electronic components.
