This circuit uses three inverters to generate a rectangular signal whose frequency depends on R1 and C1. The circuit is from a March 1996 Electronics Now.
We found this circuit in an American 80's documentation. The circuit can be adapted to function as a...
In the figure we show a way to change the output voltage of a fixed regulator, such as 7805 or...
The integrated circuits used in this project are uncommon today. It is worth the idea for a...
