10Khz oscillator
The capacitor charges until the switching voltage is reached. When the switch (SUS) is activated, the inductor causes the current to oscillate. When the current through the switch drops below the holding current, the device turns off, and the cycle...
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"...
Saw Transmitter Circuit
This circuit utilizes a sawtooth oscillator along with an output amplifier that drives a transistor. The components C1, C2, and L1 are essential for the oscillator's operation, forming a tank circuit that must be tuned to the resonant frequency. Generally,...
LC CHECKER
The circuit operates on the principle of the grid-dip or absorption effect, which takes place when a parallel resonant circuit is coupled to an oscillator operating at the same frequency. Transistor Q1 functions within a standard Colpitts oscillator circuit, maintaining...
Auto Flash Alarm - Staircase_Control
The circuit comprises a low-frequency oscillator, an electronic switch circuit, a control circuit, a photoelectric display circuit, and a music alarm circuit. The low-frequency oscillator is constructed using an integrated circuit (IC) with internal NAND gates and external resistor-capacitor (RC)...
MePADS
If you are considering building the Desert Ratt 2, it is advisable to read all the accompanying text, as it contains relevant construction details. Engaging with the comments and replies can also provide additional insights, as previous blog posts have...
Marker-generator
The oscillator section employs three sections of a 7400 quad NAND gate integrated circuit. The 1 MHz signal generated by the oscillator is input into a 7490 decade counter, which is configured to divide by ten, producing a 100 kHz...
Electronic pests killing lamp circuit diagram 4
The electronic pest-killing lamp circuit comprises an oscillator, control circuit, high voltage generator, LED indicator circuit, and power supply circuit. The schematic diagram illustrates these components. The oscillator circuit includes a time-base integrated circuit (IC), resistors R5 to R7, diodes...
Big loop oscillator
L1 is a loop consisting of 10 to 20 turns of insulated wire with a diameter ranging from 4 inches to 4 feet. The oscillator frequency, which operates between 7 to 30 MHz, varies significantly when an individual approaches or...
