This is a circuit that can be used to meter the capacitance. This circuit is similar to previous meter circuit. It has a little difference, this circuit uses transistors rather than logic gates. Here is the circuit: This circuit uses pnp transistor. if we can’t find exact type as shown in the circuit, we can use almost any pnp transistor […]

We can control the power delivered to an AC load using a phase control circuit. The AC waveform is controlled by the phase control circuit by cutting the cycle to give zero cycle, half cycle, full cycle, or somewhere in between. This circuit is looks like a dimmer circuit, but it has a litle difference. In this circuit, the switching […]

If you studying music playing, you should have a metronome. Today, electronic metronome is much more popular than mechanical metronome because the electronic metronome has several advantages. They are compact/small, reliable, cheap and very simple. Here is one example of the electronic metronome circuit : Parts: * R1 10K 1/2W Trimmer Cermet * R2 10K 1/4W Resistor * R3 330K […]

This is a current sensing circuit that senses the current at the high side (between load and positive supply). This circuit take advantage from Rail-to-Rail input of the LT1494 and the microampere supply current. Here is the circuit : At the op-amp, the output is connected directly to the inverting input that will keep the inverting input is equal to […]
