This voltage regulator arrangement is unique, since the op-amp is configured not to see either the source voltage or the output voltage directly, making it possible to regulate higher voltage while the IC is only suffering the transistors bias voltage. Here is the schematic diagram of the circuit: You can see in the diagram that the IC’s power supply pin […]

This is a metal locator circuit. This circuit is useful to detect metal. This circuit uses a AM radio and one-transistor oscillator. This circuit is inexpensive. The correct bias is provided by R1 and the frequency of oscillation is determined by search coil, C4 and C3. The search coil is formed by inductor which has varied inductance depend on the […]

Tremolo sound effect is basically an amplitude modulator. Some people might get confused with vibrato effect, but vibrato effect is a frequency modulator, big difference. When you apply a tremolo effect on electric guitar for example, you’ll hear something similar with turning the guitar’s volume knob up and down, while vibrato effect will sound like pitch bending. With electronic circuit, […]

This is a 2 MHz crystal circuit using CMOS pair. This circuit is ideal for uses in digital watches and clock because this circuit has low power drain. The oscillator in this circuit is built by connecting the One CMOS transistor pair from CA3600E array with feedback pi network. This oscillator has stable performance with 2-MHz crystal. Here is the […]
