As of control rechargeable delay circuit
This is a control rechargeable delay circuit. Under normal circumstances, when there is no input signal, the transistor VTi is off. VTz is conducting, resulting in a low output potential (U). When a signal is applied, VTi turns on, VTz...
Metal Detector Circuit with Diagram and Schematic
A simple metal detector circuit diagram and schematic using a single transistor and a radio. This metal detector/sensor project is easy to make and is an application of a Colpitts oscillator.
The metal detector circuit utilizes a single transistor in conjunction...
transistors How does this circuit diagram work
R2 controls the charging speed of capacitor C1. At a specific charge level, C1 triggers transistors Q1 and Q2, which release a 9-volt pulse. This pulse generates a clicking sound. The discharge process of the capacitor involves it charging gradually...

SOUND I F FOR COLOR TV
Utilizes three transistor stages and a Foster-Seeley discriminator to produce an audio output of 1 V peak-to-peak. -D. Bray, Solid State Makes Debut in Big Screen Color TV, Electronics, 39:8, p 99-105.
The circuit in question employs a combination of three...
Flasher-light control
The circuit is a two-stage, direct-coupled transistor amplifier configured as a free-running multivibrator. Both the flash duration and flash interval can be adjusted by turning the potentiometer, R1.
The described circuit operates as a two-stage, direct-coupled transistor amplifier, functioning as a...
Switching Improves Regulator Efficiency
In this circuit, a full-wave bridge is switched to a full-wave center tap to reduce regulator dissipation. SCR D6 switches between configurations. When D6 is off, the circuit is an FWCT rectifier using D1, D2, and D5. It applies 17...
transistor astable multivibrator
Assume one of the transistors, TR1, becomes conductive initially. Under this condition, the collector-emitter voltage of TR1 should ideally be zero; however, it will be approximately 0.1 volts, while the base-emitter voltage is +0.6 volts. As a result, capacitor C1...
Transistorized flasher
This simple circuit will flash a 6-volt lamp at a rate determined by the size of capacitor C1. It is most economical on power as it only draws current when the lamp is on. When the lamp is off, both...
