An open-source ecosystem for putting Raspberry Pi on the IoT edge

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.

Project Title: "Invisible Connections: Inclusion Beyond the Surface" Conceptual Description This project repurposes Electronic Circuit Board (PCB) design as a metaphor for the human mind and society. Just as a circuit requires varied pathways and specific components to function, innovation at Electrolux thrives through the diversity of thought and people. PCB ART/EXPERIMENTAL

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.

Build an ESP32 water quality analyzer that combines pH, conductivity, and turbidity sensors to assess river pollution.

300W TPA3255 Car Audio amplifier amplifier, The design includes 12V battery to +40V Interleaved DC-DC Boost Converter with Fuse and Battery Reverse protection.

The project is an electronic board for operating an LED array. This is a complete PCB project for managing an LED array, including a professional printed circuit board design with all the files required for manufacturing, assembly, and documentation. The circuit allows for arranging and operating multiple LEDs, and is suitable for use in display systems, smart lighting, educational, and DIY projects.
