This circuit divides the voltage of a 12 V battery by 2 and can supply currents up to 1 A at the lowest voltage output. The integrated circuit used is not very common today.
We found this sensitive moisture detector in an old documentation. The circuit uses a common JFET,...
This simple 2-transistor radio is from Radio Electronics in October 1952. The circuit outputs a...
This circuit was obtained in an American documentation of 1964. The transistors are of the time....
