A schematic diagram of the 60 Hz generator is shown in Fig. 1.
Figure 1 – Schematic diagram
Any transformer rated for 5 to 12 V and currents ranging from 50 mA to 1 A (or as required by the project) can be used. The circuit can also be used to power any project driven by a 60 Hz generator- a clock, for instance. R1 is adjusted to give the required output. An oscilloscope can be used to adjust the circuit.
