AMAZING DIY DESKTOP CHARGING STATION.IT IS MINI IN SIZE,BUT IYT HAS POWER LIKE MONSTER.

Buying a ready-made power supply would be too easy, so I decided to make my own.

DIY High Performance & Fully Protected 300W Stereo Class D Amplifier using TAS5630B for your Active Speaker or High Power Bluetooth BomBox.

Power your Eurorack modular synth with any USB-C power source.

PicoPD allows access to all USB PD 3.0 profile include PPS so that you can get the most current at any voltage out of your new USB-C charger

Build this super simple, portable, USB-C powered 0-30vdc power supply!

Battery charger with BD-type transistor

A compact and powerful USB power supply based on the XL4015 buck converter IC. Designed to deliver stable 5V up to 5A — perfect for powering Raspberry Pi, ESP32, Arduino, and USB gadgets.

Double voltage source +15V / -15V and +5V / -5V stabilized

A pure sine wave inverter is a critical device. The highly efficient 12V/24V/48V pure sine wave inverter converts the DC power stored in the battery into standard household AC power, providing you with quiet AC power anytime and anywhere. Sine wave inverters are commonly used in a variety of applications, including off-grid or backup power systems, RVs, marine, and renewable energy installations.

This is a complete PCB project for battery charging, a professional PCB design mod with all the files needed for manufacturing and assembly. The circuit is designed to charge batteries efficiently and reliably, and is suitable for use in portable systems, DIY projects, and learning electronics.
