Code-Practice Oscillator Iii
The capacitor CI charges through resistor R1, and when the gate level established by potentiometer R2 is sufficiently high, the SCR is triggered. Current flows through the SCR and earphones, discharging CI. The anode voltage and current drop to a...
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...
automatic dual output display circuit diagram
This circuit lights up ten bulbs sequentially, first in one direction and then in the opposite direction, creating an appealing visual effect. In this circuit, gates N1 and N2 form an oscillator. The output of this oscillator serves as a...
The door bell circuit
Figure 1 illustrates an economical and straightforward Gate Alarm designed to operate using a small universal AC-DC power supply. IC1a functions as a fast oscillator, while IC1b serves as a slow oscillator. These two oscillators are integrated through IC1c to...
simple electronic organ
This electronic organ is simple to construct and can provide hours of enjoyment, particularly for children. The circuit is fundamentally an emitter-coupled oscillator consisting of transistors T2 and T3. A square wave voltage can be sampled from the collector of...
Rf-genie
A variable oscillator operates in the frequency range of 3.2 to 22 MHz across two bands, enabling coverage from 80 meters to 15 meters, in addition to accommodating most crystal filter frequencies. Optional crystal oscillators at 455 kHz and 10.7...
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...
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)...
Stable Start-Stop Oscillator
Oscillators that generate a predetermined number of pulses are often required in applications such as video work. This oscillator starts 13 ms after the control signal goes high and stops immediately when the input signal goes low.
In electronic applications, pulse...
