This DIY lightning detector circuit is a very sensitive static electricity ... with its relaxation optimised via the bias resistor values shown in the circuit diagram. The oscillator is dc coupled and ...

[Jay] decided to build a device of his very own, and was impressed at its detection ... building the circuit, [Jay] noticed that the device wasn’t just picking up signals from lightning, but ...

Lightning strike detection circuit that flashes when lightning strikes nearby. It picks up and amplifies signals in the 300 kHz range, where lightning makes a lot of noise that can be picked up with a ...

Lightning is ... together a lightning detector of their own; one which keeps count of the number of discharges in the atmosphere. The device consists of a typical tank circuit tuned to 300kHz ...
