This is the circuit diagram of two tones train horn which built based dual timer IC NE556. The circuit is quite simple and easy to built and of course inexpensive. The circuit diagram is in a “basic” design, you may try to modify this circuit, for example: use a low power audio amplifier and use… Read More »
The following is an electronic circuit called galaxy audio booster which serves to improve the performance of your audio system. This circuit uses an IC RC4558 in which there are two op-amp modules that can be used for stereo audio applications. The circuit is similar to stereo tone booster that uses the principle of High… Read More »
After we present a circuit of electronic mosquito repellent, this time will be continued with a circuit of electronics that are not less interesting, that is electronic rat repellent circuit. Actually the working principles of electronic mosquito repellent and mice repellent are exactly same, using echolocation disliked by both the animal. As we know, both… Read More »
This sine wave to square wave converter circuit is expected to provide good square waves changing a sine wave delivered from an existing generator. Its primary feature consists in the fact that no power-source is required: in this manner it can be simply connected between a sine wave generator and the device under test. The… Read More »
This is a small 12W audio amplifier over a load of 8 Ω, that combining the NE5534 integrated with a pair of V-MOSFET transistor output stage technology as we get excellent sound performance. MOSFET 2SK135 / 2SJ50 from Hitachi is used in this circuit. Input sensitivity of the circuit is 3V RMS maximum, the distortion factor… Read More »
This is the electronic circuit diagram of metronome sound generator. The circuit featured adjustable volume and beats/minute with potentiometers. LED used to be a beat indication. The circuit powered with 9V DC voltage, a 9V battery can be used to operate this metronome circuit. This circuit designed by Velleman.
