A generic AC fan regulator circuit is essentially used to vary the speed of the fan.In this project, we will build our own fan regulator with minimum components and for better efficiency. Generally, ...

A tool to simulate simple AC circuits. The project objective is to develop a CAD (Computer Aided Design) tool to simulate simple AC circuits that contains only (independent voltage sources, ...

Check out this interesting wideband AC millivoltmeter circuit from 1990. The simple design features 12 ranges, decent accuracy, 200 µV accuracy, and a frequency range from 20 Hz to more than 2 MHz.

A single-side PCB for the simple 1A, 12V SMPS is shown in Fig. 3 and its component layout is shown in Fig. 4. Assemble the circuit on the recommended PCB to minimize assembly errors. Use IC base for ...
