Let's learn simple variable power supply circuits using ICs or transistors to output 0-60V at 1A to 3A with protection with basic components.

How to make your own variable tuning capacitor - Electronic Products

Description. This is a very simple AM radio circuit using only two transistors. The coil L1 and variable capacitor C1 forms the tank circuit. Transistor Q1 does the job of demodulation. The demodulated signal will be available at the base of Q1.This audio signal is coupled to the base of Q2 for further amplification. The
