Light2Heat Converter

thingiverse

Around two years ago, I experienced an enlightening moment when I discovered Cadmium Sulfide (CdS) cells could be utilized as light-to-heat converters. By applying a fixed voltage across a CdS cell, it heats up more under light exposure due to decreased resistance. This innovative concept offers numerous possibilities. In my prototype, designed for visually impaired individuals, a 5x5 CdS cell sensor array retains a heat pattern of an image after 30 seconds in sunlight. Users can perceive the image by touch. You can create your own functional object using this principle; enhance resolution, alter power sources, or even connect it to a cell phone. I shared my invention on YouTube for others to develop further, so go ahead and give it a try – just remember to thank Les!
