Pinhole camera for sun

A pinhole camera is a simple device that can be used to project an image of the sun without the need for lenses. It consists of a dark box or tube with a tiny hole (the pinhole) on one end and a surface (like photographic paper or a screen) on the opposite end to capture the image. When sunlight passes through the pinhole, it creates an inverted image of the sun on the surface inside the camera. This method is safe for observing the sun, as it prevents direct eye exposure to harmful rays.
