This is the circuit diagram of laser communication system that transmit the sound or music signals by way of a laser beam. The intensity of the laser beam varies together with the amplitude of the sound signal. The variation within the intensity of the laser beam is converted into a variation in the voltage level… Read More »
This is the circuit diagram of seismic / vibration sensor. The circuit simulates a seismic sensor to detect vibrations/sounds. It’s really sensitive and may detect vibrations due to the motion of animals or human beings. So it could be utilized to monitor protected locations to restrict entry of undesirable individuals or animals. The circuit applies… Read More »
Here is the Hi-Fi compressor circuit with pre-emphasis. The above diagram is a circuit for a high fidelity compressor which uses an external op-amp and has a high gain and wide bandwidth. An input compensation network is required for stability.
This is the schematic diagram of solar powered mobile phone battery charger. The circuit is designed to charge the battery from a source with a lower voltage. Do not use it to charge the battery with the same or lower voltage than the voltage which is generated by the solar panel. For proper operation of… Read More »
Here the circuit diagram of octave fuzz guitar effect pedal. This guitar effect unit is great sounding octave fuzz, with an optional mode of just fuzz. The fuzz is really a absolutely rectified signal and is fairly chewy. For some the Fuzz alone could possibly not be loud enough, this could be fixed by raising… Read More »
The Univibe is actually a footpedal-operated phaser or phase shifter for generating chorus and vibrato simulations for electric organ or guitar. It was introduced in the 1960s by Shin-ei, and was intended to emulate the “Doppler sound” of a Leslie speaker. Although not a really successful Leslie-simulator, the Univibe has turn out to be an… Read More »
This is the circuit diagram of Univox Super-Fuzz Pedal. This pedal is actually a 69-to-early 70″s design that consists of two special capabilities. They are the octave generation effect from the differential-pair-with-collectors -tied-together along with the option of just a clipping amplifier or a 1kHz notch for different sounds.
This is the circuit diagram of Vox Tone Bender Pedal. The circuit is very similar to Fuzz Face pedal. The Vox ToneBender will have a lot more treble response than the Fuzz Face…maybe to help brighten up those characteristically “dark” sounding British amps some. Using a Vox ToneBender with a Fender Twin, or any other… Read More »
This two chips AM radio receiver circuit is a tuned radio frequency (TRF) receiver of the standard AM (amplitude modulation) radio with broadcast frequencies at 550kHz-600kHz. This is a simple and easy to build AM radio circuit which only using two integrated circuits (IC). This circuit works with 9V voltage supply, you could use 9V… Read More »
