Ben Krasnow has built his share of odd contraptions, including a liquid nitrogen generator made from an air conditioner, and the "thirst extinguisher," a commercial-grade fire extinguisher that cools, carbonates, and dispenses his homemade beer. Now, for no other reason than wanting a real challenge, the 28-year-old engineer picked the toughest DIY project he could imagine: a homemade scanning electron microscope, or SEM. "I wanted to see if it was possible," he says.
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.

Imagine being able to examine anything you want, at the atomic level, in your living room.
