This storm detector circuit project it's in fact an receiver tuned to 300 kHz designed to detect the crackle of approaching lightning.
To increase sensitivity of this storm detector circuit you must use a long wire antenna.
A bright lamp flashes synchronous with the lightning bolts indicating the proximity and intensity of the storm.
A very simple low power AM FM radio receiver circuit electronic projects can be designed using the TA8122 integrated circuit, manufactured by Toshiba Semiconductor.
This AM FM radio receiver circuit can be used for portable radio applications or other similar devices .
This voltage controlled oscillator circuit is designed using LM111 voltage comparator and LM101 operational amplifier and some other electronic components.
Voltage-controlled oscillator circuit is an oscillator that its frequency is controlled using a voltage signal.
