I made a small DC-DC power supply for prototyping, projects, assembly and electronic experiments.

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

This is a complete PCB project for stabilizing positive voltage, which includes a professional design of a printed circuit board (PCB) with all the files necessary for manufacturing and assembly. The circuit is designed to provide stable and reliable voltage to electronic components, while protecting the system from voltage fluctuations. Suitable for use in DIY projects, power systems, and studying electronics.

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

Magnetic Visual Quantum Chip Emulator: is a groundbreaking artistic and experimental PCB that merges advanced electronics with the aesthetic language of quantum mechanics. Designed as a "Magnetic Visual Quantum Chip Emulator," this board is a functional piece of tech-art specifically crafted for magnetotherapy research and experimentation.

The capacitance multiplier reduces noise and transformer ripple in audiophile power amplifiers based on a classic ± power supply for the output stage. It was designed for a Musical Fidelity A1 amplifier (and compatible clones available on AliExpress) to eliminate power supply hum and achieve clean power delivery to the power output stage. It is capable of operating with high quiescent current in Class A power amplifiers.

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

A compact, DIY laboratory power supply platform powered by ESP32, featuring closed-loop motor control for precise voltage and current adjustment, real-time measurement, and an intuitive graphical display. Users can select from predefined voltage and current presets or save custom settings for repeated use. Designed for hobbyists and makers, it enables hands-on exploration of analog and digital circuits with high precision and flexibility, combining practical functionality with an educational and experimental approach.

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

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

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.

Plasma flame generator, based on a Class-E RF power amplifier Tesla coil, offers a fascinating and relatively safe way to create a continuous plasma discharge.

BenchVolt PD is an open-source, USB Power Delivery-based bench power supply capable of delivering up to 100 W through multiple DC-DC converters and LDO channels. It provides adjustable and programmable outputs(waveform capable), current monitoring, and real-time voltage/current display — all powered directly from a USB-C PD adapter.

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.

Monitor for equal voltage at the terminals of two 12V batteries.

This project demonstrates how to build a simple Voltage Regulator using the 7805 integrated circuit (IC). The 7805 provides a stable 5V output from a higher input voltage, making it ideal for powering circuits and components that require a 5V power supply.
