Since I don’t work at very high powers, power electronics, measurement etc. Like many electronics, I use a stone resistor, in fact, it’s healthier to use a metal type shunt..

A modification to convert an old generation ATX or older AT computer power supply to a 4AH..100AH battery charger. You can add a TL494 controlled module to the power supply..

It is very practical to make circuits with a breadboard, especially in circuits with less material. Sometimes I build mixed circuits, but usually simple circuits. In the breadboard experiments, the..

It is a very interesting circuit compared to the combination lock circuits shared before. The heart of the circuit is the button, keypad, etc. for PIC12F675 microcontroller password entry. not..

LCD Panel repair. Connection, information diagrams about COF chip (Chip On Film) repair. COF chips are small chips used in LCD panels to multiplex digital video signals. The diagrams indicate..

Amplifier D-class Music power 500W. (RMS 300W) NE5532, IR2184, KNP9120 mosfets. A simple D-class amplifier, based on a modified version. Protection of the amplifier against a short circuit at the..

The designed SMPS charger system uses both constant current and constant voltage charging methods. It can be used to charge classic, gel and traction accumulators with a working voltage of..

Temperature measurement is one of the more problematic in electronics. Digital output sensors have a very limited operating range and platinum ones are expensive. Inexpensive silicon sensors may be a..

Tone controlled stereo amplifier circuit. You can use TDA7377 or TDA7374 amplifier IC. LM1035 or LM1036 IC can be used for tone and volume control. The cooling fan control made..

The PT2314 is a sound processor with a 4-channel stereo input selector, adjustable gain, volume control, frequency loudness compensation and tone control. I implemented the Arduino nano PT2314 project, it..
