Welcome to Electronics and Electrical Engineering Laboratory.
|Power / Voltage - Voltage Converter|
This is a very simple and easy voltage doubler circuit. It provides 9V DC to 18 DC by using Max 1044 or L7660 IC .The output voltage will be slightly less than double the input because of voltage dropping on the diodes. It can be minimize if we use Schottkey diodes which exhibit a lower voltage drop. Mostly care of the maximum input voltage of the IC not to be more than 10V. This IC can only take a 10v maximum. Otherwise its damage. So lets go to make it.

Here is a VLF receiver tuned to 300 kHz designed to detect the crackle of approaching lightning. A bright lamp flashes in synchrony with the lightning bolts indicating the proximity and intensity of the storm.
