What You Can See with a SEM?
The last time we used a scanning electron microscope (a SEM), it looked like something from a bad 1950s science fiction movie. These days SEMs, like the one at the …read more Continue reading What You Can See with a SEM?

How We Got the Scanning Electron Microscope
According to [Asianometry], no one believed in the scanning electron microscope. No one, that is, except [Charles Oatley].The video below tells the whole story. The Cambridge graduate built radios during …read more Continue reading How We Got the Scanning Electron Microscope
Viewing Atoms with Electrons
When we were in school, they always told us we can’t see atoms. If you have an electron microscope, then they were wrong. [AlphaPhoenix] has access to a scanning tunneling …read more Continue reading Viewing Atoms with Electrons
Home Made Scanning Electron Microscope Show Some Potential
Scanning electron microscopes are one of those niche instruments that most of us don’t really need all the time, but would still love to have access to once in a …read more Continue reading Home Made Scanning Electron Microscope Show Some Potential
Electron Microscopes Are Awesome: Everything You Didn’t Know You Wanted to Know
Electron microscopes were once the turf of research laboratories that could foot the hefty bill of procuring and maintaining such equipment. But old models have been finding their way into the hands of eager individuals who are giving us an inside look at the rare equipment. Before you start scouring Craigslist, go on a crash course of what you need to know with Adam McComb’s Hacker’s Guide to Electron Microscopy. He presented the talk at the 2018 Hackaday Superconference and the recording was just published, you’ll find it below.
Two Ways to Make the Really Small, Big
The first thing …read more

Scanning Electron Microscope Adds to Already Impressive Garage Lab
When you’re a high schooler who built a semiconductor fab in your garage, what’s next on your agenda? Why, adding a scanning electron microscope to your lab, naturally. How silly of you to ask.
When last we stumbled across the goings on in the most interesting garage in New Jersey, [Sam Zeloof] was giving a tour of his DIY semiconductor fabrication lab and showing off some of the devices he’s made there, including diodes and MOSFETs. As impressive as those components are, it’s the equipment he’s accumulated that really takes our breath away. So adding an eBay SEM to the …read more

Nascent Project: Open Source Scanning Electron Microscope
I used to have access to some pretty nice Scanning Electron Microscopes (a SEM) at my day job. While they are a bit more complex than a 3D printer, they are awfully handy when you need them. [Adam Guilmet] acquired a scrapped unit and started trying to figure out how to breathe life into it. His realization was that a SEM isn’t all that complicated by today’s standards. So he has set out to take what he has learned and build one from scrap.
In all fairness, he has a long way to go and is looking for help. He …read more
