Usually a single LED that flashes with each discharge.
Most versions of this schema use a high-gain transistor stage (often a Darlington pair or multiple stages) to amplify the tiny signal picked up by a telescopic or wire antenna [3, 4]. While sensitive enough to detect strikes from tens of kilometers away, they are prone to "false positives" from household appliances, thermostats, or light switches [4]. shema indikatora grozy
The (Lightning Indicator Circuit) is a popular DIY electronics project often featured in hobbyist literature and forums (like Radio magazine) designed to detect the electromagnetic pulses (EMP) generated by lightning strikes [2, 3]. Overview of the Circuit Usually a single LED that flashes with each discharge
Simple schemas cannot distinguish between a weak nearby strike and a strong distant one. Both will trigger the indicator similarly. The (Lightning Indicator Circuit) is a popular DIY
