DIY Perks builds a realistic artificial sun for dark winters, using a powerful water-cooled LED, a satellite dish reflector for near-parallel rays, and a scattering layer to mimic the blue sky. The video explains the optics behind why most lamps do not look like sunlight and shows the build and its results.
HNで推薦される理由: Whenever HN discusses seasonal affective disorder, myopia, or bright home lighting, people point to this as the most convincing buildable example of sunlight-like illumination.
