Have a spare oscilloscope, an electron gun, and a handful of spare weekends? DIYer Ben Krasnow has spent the last few months building a homemade scanning electron microscope in his workshop, and yesterday he generated his first image. To celebrate, he’s shared his setup via this video explaining broadly how he did it.
As DIY projects go, we’re going to rate this one “difficult.” By Krasnow’s own estimation, it took him two or three months to get the beam under control. But generate an image he did, and the entire rig is pretty impressive, especially considering he put the whole thing together in his shop, partially from parts he had just laying around.
The video below offers a pretty thorough overview of the project as it stands right now.
