This 10-channel equalizer with loudness feature operates with a ±12V DC symmetrical voltage. Current consumption is approximately 40mA. The slider potentiometers are rated at 100 kOhm with a 30mm stroke…

This is an online electronics simulator that you can use to simulate Arduino, ESP32, STM32, and many other popular boards, components, and sensors online. Key Features WiFi simulation – Connect..

The battery monitoring and maintenance device monitors the battery voltage and notifies you of the need for charging with an audible alert. It’s a simple, dual-function circuit. It maintains and..

After reading the article “Using CircuitMaker,” I wondered about the status of Eagle Cad, which was acquired by Autodesk. Perhaps some nice features have been added, such as innovations in..

Profilo Dishwasher Won’t Turn On Problem and Motherboard Repair: In this article, I’m sharing in detail the motherboard repair I performed for my Profilo BM3120EA dishwasher that wouldn’t turn on..

In power electronics, an active DC rectifier module using MOSFETs increases efficiency and minimizes losses. MOSFET rectifiers can advantageously replace both classic silicon diode and bridge rectifiers, as well as..

A simple current direction indicator device for monitoring current balance in older vehicles, battery chargers, UPS backup power supplies, or differential devices. A two-color LED is used for the current..

Some battery-powered electronic devices are designed for occasional use. Users often forget to turn them off, which causes the battery to drain quickly. In particular, some multimeters lack an automatic..

I recently replaced the shock absorber felts on my washing machine. When I saw the wiring I made years ago for Electricity Savings, I decided to write this article. We’ve..

The circuit is primarily designed to monitor, control, and protect the temperature of a power supply’s cooler. It can also be used in amplifiers and other cooler-equipped circuits. It can..
