My friend Ben Krasnow, who is one of the most talented makers-of-amazing-things I’ve ever met, used his home-made sxanning electron microscope to make an extreme close-up video of a turntable needle running in the groove of an LP. The video is fascinating because he explains everything he has to do to make the animation. He had to cut a small square from the LP that would fit in the microscope chamber, coat everything with a thin layer of metal, and more.
