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.

he project is an electronic circuit for regulating negative voltage (Negative Voltage Regulators). This is a complete PCB project for stabilizing negative 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 a stable and reliable negative voltage to electronic components, while protecting the system from voltage fluctuations. Suitable for use in analog systems, symmetrical power supplies, DIY projects and studying electronics.

One of my first PCB reverse-engineering projects.The board is two-layer, with components soldered only on the TOP side.There are no components soldered on the BOT side.

Punched paper tape can be decorative, so this script can create PDFs full of them.

I was part of a team that built an automated marble sorting and lifting machine with three unique mechanisms. My specific role was to architect and execute the entire electronic nervous system. I solo-designed and fabricated a custom PCB that integrated dual microcontrollers, motor drivers, Bluetooth, and robust power regulation. My parallel-circuit design guaranteed no single component failure could take down the whole system. I delivered a professional, reliable control hub that brought our team's mechanical designs to life

An attempt to make programming the MPF-IB as easy to program as an Arduino.

I bet you wouldn’t have guessed this Colorful Carousel was made entirely using PCBs

In this tutorial, I am going to show you guys how to design this "Transformers PCB Badge" and how to solder the components to it.

The Linear Keyboard provides the amazing feel of a full mechanical keyboard and allows you to take its small form factor on the go!

its good
