Make a pinhole camera and trace the path of the sun across the sky
Try our DIY pinhole camera project for a low-effort way to trace the path of the Sun across the sky.
Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a ...
