Ben Krasnow’s Homemade Electron Scanning Microscope and Liquid Lens Coming to Maker Faire

Ben Krasnow is one of the coolest makers I know. From his backyard lab in Redwood City (a stone’s throw away from Maker Faire — well, maybe with the aid of a trebuchet) Ben makes things that usually require a lot of money and sophisticated equipment: an electron scanning microscope, silica aerogel, and freeze-dried astronaut ice cream (I’ve tasted it, and it’s spectacular). Ben also builds electromechanical hardware for Valve Corporation, the famous game developers behind Half-Life.

Ben is coming to Maker Fair again this year, and he’ll be demonstrating his electron microscope on the Make: Demo Stage on Sunday at 2:30 PM. The rest of the weekend, he’ll be showing his work on liquid lenses “that change focal length based on the electrical potential applied to the lens. This makes use of a phenomenon known as electrowetting.” See Ben’s liquid lens video here.
