The designed laser light barrier can provide reliable detection at a range of 100 meters and more. In this design, which uses a continuously operating wave (CW) laser diode in..

A difficult-to-implement 3-phase inverter project. It can provide inspiration for different projects, and its documentation is very good. Full project files prepared with Altium Designer, heatsink 3D drawings, STM32 source..

The most common faults encountered in PPRC welding machines are heating element problems, cable breaks, and issues caused by the on-off switch. I encountered a thermostat failure in a small..

The TDA7377 amplifier circuit is one of the projects I implemented years ago. The TDA7377 integrated circuit is used in many audio systems because it provides various output combinations, is..

The circuit effectively protects the sensitive tweeter within a speaker cabinet from overload. It was specifically designed to prevent damage to tweeters, particularly at high volume levels and under faulty..

Staircase light switch with 2 different trigger modes. The circuit functions as a classic staircase light switch. When the supply voltage (230V AC) is applied, the system enters standby mode,..

This is a project to repair a faulty volume control potentiometer on an Odyssey-U-010 amplifier. In the original setup, large resistors were soldered to the top. Instead of using a..

The Battery Capacity Meter allows you to measure the capacity of any battery or accumulator; it can also be used as a precise voltmeter, milliammeter, and power meter. It discharges..

The Digital Circuit Construction Simulator with Virtual Scenarios and Interactive Tutorials is a program for building digital circuits on a virtual digital module using logic models of standard integrated circuits..

This is a simple circuit for creating electronic music boxes, doorbells, etc., using ringtone sounds. You can build this music box circuit with very few materials. In this project, a..
