This story has been all over the web lately, and deservedly so. Ben Krasnow has built a scanning electron microscope, from scratch, in his garage!
This type of project is the essence of hacking and is the type of thinking and project building that I want to be doing and showcasing here on the hacker workshop.
Go view Ben's video. He does a great job explaining his invention. And did I mention he built an electron microscope from scratch, in his garage!
Amazing. Ben, my hat's off to you. I can't wait to see further refinements of his project.
