Suggested by an American documentation from the 90s, this circuit generates signals with frequencies determined by the capacitors and calculated by the formula next to the diagram.
We found this circuit in a 1987 Hands On Electronics. It was indicated at the time to power...
This high current regulator was found in documentation from 1977. Transistors are types of power at...
