- tsomctl 11y agoOn a related note, Ben Krasnow built a SEM in his garage. Search YouTube for his channel.

- fpordeig 11y agoKnowing nothing about Electron Microscopes, I found the design of the motion mechanism very clever: http://web.archive.org/web/20130927064954/http://www.geocities.com/spm_stm/Disk_Scanner_Exp.html http://web.archive.org/web/20130927064954/http://www.geociti... http://dberard.com/home-built-stm/scan-head/ http://dberard.com/home-built-stm/scan-head/
- femto 11y agoAlso of interest is that the inventor, John Alexander, submitted a patent application (US5866902), then withdrew the application. Perhaps this was done to establish prior art in the USPTO's database, and prevent someone else from patenting it?
- cxseven 11y agoI'm looking forward to something like this rescuing a few harddrive platters.
- Osmium 11y agoNice to know they're not magic after all :) Very inspiring.
- aswanson 11y agoNice project. Had no idea the electronics were so simple.
- irremediable 11y agoWow. Stuff like this makes me want to get off my ass and do something cool. Really reinvigorates my passion for hands-on science and engineering, as opposed to the maths and code that I usually look at.
- aaggarwal 11y agoThis is super cool. Bookmarked. It would be awesome to see it working. I wonder if there is a video on this. This project uses PI control in the feedback loop. I am curious if the author also tried PID control, that would have been faster with correct tuning.
