This project represents one of my early designs, completed in March 2015. Utilizing the Texas Instruments BQ2557 energy harvesting IC, the circuit enabled efficient battery charging from a single solar cell. The initial concept was to develop a device for environmental monitoring, but the scope ultimately exceeded available budget and resources.

While most documentation for this project has been lost, one image remains—a custom light fixture incorporating the module. The energy harvester can be seen in the lower right corner, with the solar cell positioned behind several diffusing layers.
