Schematic Diagram of Power Supply

The circuit is constructed using two 555 timer integrated circuits, designated as U1 and U2. U1 is configured as a variable duty cycle oscillator with a fixed time period of approximately 0.1 seconds. The duty cycle can be adjusted...

Displays are always beneficial. Until now, only 7-segment displays have been demonstrated for showing numbers using minimal resources. However, for displaying text or images, a simple LCD screen is required. There are basic LED screens available that operate on...

Most modern transceivers feature a built-in interface that functions effectively in digital modes; however, they often lack support for analog voice modes. For instance, Yaesu transceivers only allow the use of their internal interface when transmitters are set to...

Each subsequent stage adds 1700 volts, resulting in more than 20 kV with 12 stages. However, this voltage can only be achieved when the output of the cascade is unloaded. The described circuit appears to be a high-voltage cascade generator,...

The image below depicts a block diagram of a complete mixer that consists of four input amplifier modules followed by four switchable tone management modules, one stereo line input, four mono main faders, one stereo dual-ganged main fader, four...

This simple circuit tests speakers, microphones, transformers, and voltage. It is essentially a very low-frequency oscillator that produces extremely short "fruity" pulses. The sound produced is easy to hear and allows for precise determination of its direction, making it...
