Shruthi-1 Sound Filter
The Shruthi-1 is an impressive hardware synthesizer equipped with the highly regarded SMR-4 MkII filter board. Developed about a month ago, it has become a favorite tool for sound exploration. As a sound designer, there is a continuous drive to...
Metal detector 4
The metal detector circuit comprises a detection oscillator, a reference oscillator, a mixer, and a signal display, as illustrated in Figure 8-70. The detection oscillator circuit is made up of the time base oscillator IC1, inductor L1, potentiometer RP1, diode...
Wireless keyboard circuit
The circuit operates with VT3 and associated components arranged as a common-base capacitance feedback oscillation circuit. The oscillation frequency is set by capacitors C8, C9, and inductor L1. VT2 serves as a voltage amplification stage that reinjects the audio signal...
freeze protector circuit
This is a simple freeze protector circuit diagram, also known as a timing circuit. It serves as a hobby project for beginners. This circuit can automatically operate any device after a fixed time once AC power supply is restored. The...
Electronic Drum Synthesizer
The circuit consists of two twin-T oscillators set below the oscillation threshold. To initiate oscillation, a touch on the Touch Pad is required. The schematic diagram illustrates the circuit, where different touch patterns on the pads can create a variety...
timing circuit
Assistance is needed for the design of a timing circuit intended to activate a spark plug every 10 or 20 revolutions of a shaft.
The timing circuit for firing a spark plug at specified intervals can be designed using a combination...
oscillation Oscillator circuit
The first thing to understand is how capacitor C1 is related to the resonance frequency f of the circuit. It appears that selecting a frequency allows for the automatic determination of the necessary value for C1. There are uncertainties regarding...
Wide-range-oscillator
The gain control enables the oscillator to maintain a nearly constant output across its range. The circuit operates within a frequency range of 160 kHz to 12 MHz while producing a consistent amplitude.
The oscillator circuit described utilizes a gain control...
Sonic Defender
This oscillator-driver produces a loud sound of approximately 3 kHz, modulated with a 10-Hz warble. BZ1 is a Matsushita EFB-RP3. U1A generates the 10-Hz waveform that modulates the 3-kHz tone produced by U1C and U1D. Q1 drives the transducer through...
