DIY Scanning Electron Microscope – Overview

Today, I finally produced an image with my DIY scanning electron microscope. I’ve spent the last few months working on this project, and am encouraged by today’s success. There is still a lot of work left to do in making the image higher resolution, and eliminating sources of noise, however this image proves that all parts of the microscope are operating as designed. I will be showing this project at Maker Faire 2011 in San Mateo. Come see it for yourself in person! Search my blog for “microscope” for additional images and info:

    You sir, are a credit to the species! Amazing work you’ve done! You must make your parents very very proud!

    Interesting, so a scanning electron microscope is essentially a CRT television, except the beam is focused onto a small area rather than projected onto a large screen. Seems like the most complex part is the electron sensor and all it does is measure the instantaneous “brightness” of the reflected electrons and convert it into a voltage. Looks like it would be relatively easy to ditch the o-scope and add an LCD display for a nice “finished product” look. Thanks for the informative video!!!

    He says it on another video but it’s mechanical engineering. But he says most of the stuff he does he learned on his own

    Wow, this is great. What kind of schooling do you have? I’m looking up oil diffusion pump right fat is you oscope, I’m guessing 500 or faster? I learned a lot thanks. Can’t wait to see your other vids

    I love the spark-plugs, what a great use of such a simple object and it suits the purpose perfectly. wonderful engineering overall!

    This is absolutely fantastic stuff, you ought to have your own TV show.

    I wouldn’t trust an Apple extinguisher.

    This is just unbelievable! A scanning electron microscope is not the first thing I would think of as a DIY project. This is one of the most interesting videos I’ve ever come across on Youtube. Congratulations!

    what education do you have sir?

    i like your project. i’m looking forward to learn more. Would it be possible to display the subject on a lap top? hope to hear from you.

    Ben, Loved your new article in Make on this subject. Might it be possible to use the electron gun from a TV with the deflection plates intact to make a simple Scanning microscope? Better focusing may be in order. -Chris

    holy crud, this video is off the hook. science in yo face!

    An Apple fire extinguisher? How innovative!

    Very interesting video, I’m not sure NGK ever intended their products to be used for an electron microscope lol

  16. papapoutsoras says:

    this is the best video i have seen in youtube ! Congratulations.
