An e-ink photo frame that runs forever.

A low-power ESP32-based battery monitor and weather display built with ESPHome and designed for easy integration with Home Assistant. This project turns a WeMos LOLIN D32 board into a smart, ultra-efficient sensor node that reads and displays battery voltage, charge status, environmental data, and weather forecasts on a Waveshare ePaper display.

A battery-powered E-Paper weather station using ESPHome and Home Assistant.

🔧 Build a modular, power-aware firmware system for STM32 with CLI dashboard, logging, and sensor abstraction for efficient embedded solutions.

📂 Portfolio of embedded projects with MSP430G2553 board.

A configurable Arithmetic Logic Unit (ALU) supporting 12 operations with parameterized data width. Designed with low-power techniques including clock gating and operand isolation. Simulated using Xilinx Vivado WebPACK with waveform verification.

This repository contains the design, simulation, and analysis of a CMOS Inverter using industry-standard tools like Cadence Virtuoso. The project focuses on understanding and optimizing the fundamental building block of digital circuits—the CMOS inverter.
