I was the rare individual who was intrigued by junk lying around for collection, outside my university's science departments, a proclivity not shared by my friend. She thought it a bit weird. Fact is, I shoulda been going between classes in a pickup.

Hey there. Add one more comment to the list.

Absolutely awesome Ben. Can never get enough of SEM photos, simply fascinating - and I love how the MDO is being used as the data acquisition engine. The HiRes sampling mode, with the amount of boxcar averaging you're getting, is giving you many more bits of vertical (video) resolution. Simply great!

@AppliedScience

9 жыл бұрын

Alan, thanks so much! I wondered if the Hi-res mode allows the scope to output more than 8-bits of vertical information. It looks like it does from the smallest deltas in the CSV file. Very handy feature!

@w2aew

9 жыл бұрын

Applied Science Yes, you'll get an extra 0.5 bits each time the # of bits averaged doubles. Thus, If Hi-Res averages 2 bits, you get 8.5 bit resolution. If it averages 4 bits, you get 9 bit resolution, and so on. The MDO3k samples at 5GS/s on a single channel. When you set the record length and horizontal scale, you effectively set the waveform sample rate (reported on the bottom right of the display). The number of samples averaged in hi-res mode is then 5GS/s divided by the indicated waveform sample rate. Thus, if the waveform sample rate says 500MS/s, then 10 samples are averaged to create each waveform sample point, giving you just over 9.5 bits. Fixed point math hardware limits the progression at some point...

If we had teachers like you in the university, things would have moved a lot faster ! :) Great video !

Very nice. Since a SEM can seemingly be a rather simple device with low speed low cost image acquisition electronics and USB interface, I wonder if you might consider seeking venture cap funding and do a kind of makerbot SEM for the people. You could just start it up and pick some people to implement your directives so you don't actually have to do anything.

Ah! That was very satisfying to watch! I love it when I can actually understand what's going on in an SEM and you let us know how the to convert data into information through your thorough manipulation of the signal.

Those images are fantastic, and the processing involved is ingenious!

I'm totally amazed by your technique and finesse Mr.Ben!

This is my favorite channel on KZread. Don't stop the great videos!

What a fantastic piece of equipment revived!

Thanks for taking the time and sharing your experiments and results; but most importantly, your knowledge.

Wow, what an incredible job you've done.

Wow, your channel has some of the most interesting things on the net, and this is one of the most impressive. Bow to you sir.

Perhaps you could take scan requests from us laymen and let us glimpse into the microscopic world all around us. Not everyone in the world has the opportunity to use an electron microscope so! Maybe a monthly episode dedicated to showing some of the stuff people requested to be seen? I'd love to see some pollen/plant scans :)

Those images are amazing. They have such bold tonality while still being illustrative. I think a book with images of this style would be popular.

Dude, your methods and techniques blow my mind. You're an insane genius.

you never cease to amaze with your projects. keep it up!

Absolutely beautiful piece of equipment, looks like so much fun to play with

You're absolutely genius. Loved this project

Your genius continues to blow me away! Absolutely amazing!

Restoring my faith in humanity one video upload at a time. Thank you.

Great images and excellent explanation about to set up the oscilloscope to properly capture the frame. I'm glad this perfectly working piece of equipment wasn't just thrown away, unlike so many others.

This is absolutely incredible.

Amazing! Thanks for sharing. Always enjoy watching your videos.

That is a gorgeous piece of equipment.

Im impressed by the technique ! The way you use the oscilloscope...so cool

Fascinating tech, extraordinary images.

Man, you're awesome.. when I subscribed to your channel; long before the rename, I knew your channel had potential.. but I never anticipated all the amazing things you've done.. especially not recording digital images from an analog SEM the way you did.. you kick-ass!

Dude, you are amazing. Not just by collecting this odd stuff and doing videos, but literally walking us through principles of functioning, caveats, physics behind certain devices and processes... Literally i was searching to "how to build microscope out of camera lenses", ended up at AS again being unable to move through whole video. Thank you :D

Genius in our mist! Amazing talent!

Once again ... brilliant stuff Ben .. Would love to see more images of interesting things

You are an inspirational scientist, who knows science and can use technology into.

man you're amazing !!!!! Im always soo desperate to see your ideas that you use !!! keep up the great work BEN !!!

This is really incredible!

Hi Ben, Another cool trick you can try with the EM is imaging the internal structure of chamber, like having a mirror inside the SEM. Mount a coin shaped disc with smooth side under the beam. Apply high kV (30kv) on the disc, let it charge up for about 5 mins. Then switch to low kV ( 3kv, or 4). You will see image of chamber, with a sort of fish eye lens effect.

Really, really awesome, Ben!!!

Wow, those images are awesome quality.

Very cool images. And I thought I ran out of drool the last time you showed us tricks with this scope. :)

This is such an excellent video. I have been spoiled by new SEMs and it is so nice to see how one works without advanced computer technology. I can't wait to see more videos about your instrument!

I cannot express how impressed I am by this

Honestly ! you are one of the most important scientific brains in the world. Keep going Sir.. and thanks for your efforts

Amazing work !

Knowledge, inspiration, and tee-shirt acquired!

Really awesome video, and very succinct explanations to go along with the process.

You show things that I thought are not possible with a 'simple' scope. Very impressive.

How about a timelapse of something getting degraded by the electron beam. BTW how long does it take to pump down? Does it pump the whole chamber or is there an airlock for the sample chamber?

@AppliedScience

9 жыл бұрын

You may not need a timelapse to see damage caused by the beam. I was looking at strands of hair, and at 25KV with a large spot size, the beam will start to "bubble" the hair. It creates a fairly large blister in 5-10 seconds. Yikes. This SEM pumps the whole column down as one unit, and doesn't have an airlock or nitrogen purge. It only takes about 10 minutes to change samples, though. It also has two separate stages for small and large samples, which can be manipulated separately, and a few unused blank plates (I'll add electrical feedthroughs).

Applied Science Hello Ben, are you afraind of X-ray radiation when the electrons are de-accelerated? I mean, the glass bell do not protect you very well.

@AppliedScience

9 жыл бұрын

Alexander A. The DIY SEM used acceleration voltages of under 10KV, and X-rays generated by these relatively low speed electrons will be stopped by a very thin layer of glass, so the bell jar is more than sufficient. Black and White televisions did not have lead shielding for this reason. The JEOL uses acceleration voltages up to 25KV, but the chamber is relatively thick stainless steel, and this sufficient to stop the X-rays generated by the beam, which is already extremely small (50uA emission current).

Very nice! And informative! Excellent explanations of basic phenomena.

Absolutely amazing. Well done!

You're a tech ninja man. Really cool work.

Really amazing work you are doing! Beautiful detailed images at the low scan rate. I really appreciate that you take the time to communicate challenging topics in a clear and concise way that allows the non specialist to get a handle on these interesting machines. Subscribed! Might even get the tee.

This makes me feel like the laziest man in the world. Being able to problem solve with such practical clarity means your work will always be ahead of the rest, likely in any domain. Applied indeed! Glad I found the channel. SEM has captured my imagination since childhood. Surface opacity makes every image so much more relatable compared to light and optical microscopy. Much more "as if you were there" in the micro world.

Thanks for the great video Ben

EXCELENTE TRABAJO, me encanta ver cosas como esta!

Your videos always impress, Ben, but this one is quite special- very exciting to see how this reasonably simple method improves the visual quality by so much.

I really appreciate the information and experiences you share in your videos! This one really impressed me and I can't wait to see how having a real SEM enhances your future exhibitions.

Even though I will probably never replicate this, I still learned a ton from your video. Really interesting, I would love to see more on this. Thanks!

Absolutely loved this vid.

Amazing!! Seeing something like this just gives any engineer joy. Please do more videos on the complete physics behind the working.

Yet another amazing video!!! Nasssty!! I need that T-shirt now!

Thanks! I really appreciate it. It's often a good idea to learn from people that you suspect know what they are doing, however I'd be careful about assuming there is anything "best left to the pros." No one is good at doing anything when they are born -- it simply takes dedication and interest to develop skills as well as the courage to try something and fail a bunch of times.

Wow ! This is just awesome !

That is very impressive. Great job - keep up the good work!

That's just awesome. Thanks a lot; it all doesn't sound very complicated when you explain it, but I guess a lot of engineering has gone into this 1980's beast, I particularly imagine the electron beam focusing to be a crucial parameter.
