Metal detector circuit diagram 8
The metal detector circuit consists of a probe oscillator, a PLL (phase-locked loop) circuit, and an audio alarm circuit. The probe oscillator includes a detection coil (L), transistor (V1), and several resistors (R1 to R3) and capacitors (C1 to C5)....
HEE HAW ELECTRONIC SIREN
The oscillator based on IC2 generates sound, with its output linked to the base of TR1, which amplifies the signal to drive the speaker. Resistor R4 is included to limit the current through TR1 to a safe level. The oscillation...
Frequency Generator:
Building your own Zapper. It requires one capacitor of 1 microfarad (C2), preferably unpolarized to eliminate concerns regarding positive and negative terminals. If a polarized capacitor is used, the longer leg indicates the positive side; refer to the schematic for...
Acousto-optic detector circuit to measure the crystal
The circuit consists of a capacitance three-point oscillator, an isolation level, a voltage doubler rectifier circuit, a stereo sound circuit, and a flash display circuit. It can detect the quality of a crystal; a good crystal will emit a "Didi"...
pills reminder schematics
The clock circuit is constructed using a stable oscillator that consists of two inverters integrated into IC1 and a watch crystal that oscillates at 32.768 kHz. This frequency is divided by 16384 through the internal flip-flop chain of IC1, resulting...
Half-duty-cycle-oscillator
The frequency of oscillation depends on the Rl/Cl time constant, allowing for frequency adjustment by varying Rl. This is a basic circuit.
The described circuit operates based on the relationship between resistance (Rl) and capacitance (Cl), which together form a time...
Variable Duty-Cycle Oscillator Circuit
A 1.2-kHz oscillator utilizing a potentiometer and steering diodes allows for a duty cycle adjustment ranging from 1% to 99%. The frequency can be altered by varying the capacitor CI. It is important to note that the diodes may slightly...
Rectangular/Triangular Waveform Converter
Many function generators utilize a rectangular waveform generator that comprises a Schmitt trigger and an integrator. The triangular signal generated by the integrator is subsequently transformed into a sinusoidal signal using a diode network. The converter described here operates inversely,...
7 Standard Step Frequency from Frequency Generator
The circuit was designed to create a frequency generator that consists of seven steps during operation. It includes a crystal oscillator, which is an electronic circuit made of...
The frequency generator circuit operates through a series of seven distinct steps, each...
