Because maybe someone's supposed to donate a more modern electron microscope to him (and he can donate his old one to me -- I'd use it to identify patients' pneumonia-causing bacteria without needing the slow lab-cultures). :D :/
Here is an old video I made before I sent it from Sweden to Ben in California: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Mw5O2XikYus.html Edit: Just to clarify, Ben kindly payed for the shipping, which was not cheap considering it weighs close to 300 kg (600 lb).
@@cantsolvesudokus Unfortunately not, the one Ben has now was taking up too much space in my apartment hence I had to get rid of it. At approximately the same time period Ben was building his DIY SEM so I asked him if he was interested.
Love the idea of more SEM animations! SEM microscope images are cool, but adding panning, rotating and zooming to the images really makes them come alive!
Your channel is just so good with the quality of content you post, and extremely interesting. So glad I found your channel years ago, keep up the good work.
Wow, that's honestly the most stunning electron microscope animation I've ever seen 🤯 Your technique of getting a continuous zoom with discrete input worked really well. Just as I was thinking "he ought to put some steppers on those knobs" you mentioned your plan to do just that 😄 Thanks for all your work feeding my curiosity!
I have been in the carbon nanotube field for almost 20 years. Anyone who says they understand this technology is lying. The true breakthroughs will come from tinkerers and experimentalists playing around like this. Keep going.
Love the video, love the way you use the SEM, reminds me of when we built the SEM in the garage by cutting the screen of the old oscilloscope (you get x-y control for free) and mounting it into the vacuum chamber to inspect flat panel display traces (if you energize them you can see them - sem can pick up 5V difference in float voltage). We got very wide field of view (>10cm) at high enough resolution. Post more!
This is awesome! I'm an animator and this tool would open up a world for me in terms of my animations. As soon as I saw it I thought stepper motors. I truly look forward to seeing this project. Thank you. You are doing something beautiful
Did I ever tell you how awesomely scientific education you share and have shared? Completely impressed. I consider this channel as pure ‘information’. I have gained enough resolution to stop. Mad respect.
Ok...I watch a lot of scientific youtube videos and this is science PORN! Amazing job. We as a learned community of enthusiast don't get to see things like this often. BRAVO!
What is this? A carpet for ants? Oh... I guess it is I miss working with electron microscopes. Last time I used a similar device I got to move iron metals around. It was exciting for about 2 minutes and after that I started questioning my life choices.
The fact that you get all that you do, out of such an antiquated machine as that, is astounding! Can't imagine what you could achieve with a modern rendition... Awesome man...
Epic video. You make extremely marvelous videos here on RU-vid and have so many equipments and knowledge and the know how to apply this and carry it out. Your work does not go unnoticed. We highly appreciate all this work and thank you for always being an excellent source of entertaining and educational Applied Sciene!
Man, I want to be you in 10 years! You've built an electron microscope, a laser, x-ray machine, made crazy glass that changes color in UV light and tons of other bleeding edge science things. I can't think of anyone who is so versatile and has so much knowledge about technologies of the future. I tip my hat to you Sir.
Hey! I met the guy who gave you this SEM today and he pointed me to this video. Great job on showcasing vintage tools! Quite a nice image for the size of the tool also!
Ben continues to deliver top quality content to the internet and long may it go on! You know, I've always thought he missed a career in teaching, then I think, "Naah, we would have this channel?", and alas, selfishness wins every time :-) So little really top notch content out there, this stands out as a pearl.
@@dimitar4y I have no idea, I just dream of a really terrible looking knitted jumper, probably beige, but it can stop tank rounds of something. All soldiers looking like middle aged northerners. With attack slippers, pipe grenade and highly trained death whippets.
Carbon nanotube-coated kevlar armor has been on the market for years. The coating greatly improves the kevlar's structural integrity and shelf life, even making it waterproof. Bullets that are stopped by the kevlar weave tend to embed themselves in the material, but the coated armor can protect it enough for bullets to bounce or barely stick to the vest itself.
Yes, found it interesting. Thank you for your effort pulling ;] this off. Seriously, kudos. I also find it interesting that this video disappointed 38 people to such an extent that it motivated them to register a dislike. If they could all be interviewed, that too would make for an interesting video.
While I don’t fully understand how you do what you do (though I learn much through your explanations), I certainly appreciate your passion for it. Thank you for sharing.
thumbs up within the first 5 seconds of his video because of how much work and how awesome this guy is to share his interesting life....i can only hope to have half of the cool stuff he has made videos on.
I have to say, any one of your videos would have me thinking the person behind it was very well versed in the subjects being discussed. But to see how many subjects you cover, and at the depth/degree you dive into them, it is really very humbling I must say. Most science video channels I don't feel intimidated at all, but this channel is a different story. You have to be one of the very brightest people on youtube. Again, namely because i don't think i have seen another channel that goes into the same depth on such a breadth of subjects. I don't know of another channel that comes close. Glad to see your subscriptions are growing, well deserved... thanks again for producing these, super interesting stuff...
Thanks so much for these videos , it's amazing how important these videos are. There is a complete lack of good information on the graphene manufacturing process and carbon fiber. Almost everything is glossed over, hard to find or inscrutable. Like just looking into carbon fiber means having to sift through the mountains of "DIY carbon-fiber" thats about bloody vinyl stickers. But here you *literally* show discrete parts of it, thanks.
600 stitched single frames, huh. "Painstakingly" must be an understatement. You document your (already) fascinating projects so well, and it's so interesting to see how you use mostly common tools to achieve remarkable things. Thanks for continuing with these posting.
This is incredibly cool and incredibly impressive. I am constantly awed by your skill and knowledge, but now also by your patience in collecting those frames!
The WHO has a publicly available document that details how small organizations can manufacture their own hand sanitizer solution. They list two formulations. This would be a cool, easy, and topical subject for a video. Thanks for always making great content!
Each time I think that you cannot top your last video in terms of quality, engagement, inspirational effect, educational value and general technical/scientific impact, you do. You continuously seed your audience with skills, ideas, and insights that they’ll carry with them into their scientific and processional careers, or journeys of curious discovery. Thank you.
Ben You are great. I love the content and all of your videos so far. I even found the few presentations not on your channel that were totally worth watching. After screwing around with many different ccd spectroscopes I finally have a PMT on the way! So thank you for your guidance. Previously you helped me with scattering silver on to glass. You really are an awesome human for sharing your knowledge. Thank you. If you plan on taking your delorean to half moon for another show you should totally let us know. Id love to thank you in person.
I’m at work. Am lead systems engineer for big department at nice company. I have a good Friday where I fix problems others couldn’t figure out. I go home feeling pretty good about myself, maybe I’m not that dumb. Then I watch any video by this guy ;)
I never bother to judge coming here by the title of the video........... I just always click right on over no matter what. Pretty awesome potential in that new project .........I hope you do it.
Just a small tip, because I noticed you use your fingers to set up your sample in the chamber: It's best to avoid touching anything going into the specimen chamber with your bare hands. There will always be at least some residual oil from your fingers. Over time you'll wind up with a carbon deposition over everything in the chamber, inside the column and in the electron gun itself. That will continually degrade image quality and cause serious problems in the microscope down the line. If the carbon deposition gets bad enough it could cause arcing and serious damage to the microscope. It's a good idea to always wear gloves when touching any part of the specimen chamber, samples or sample stubs for SEM, or to use tools that can keep your fingers away from them like forceps designed for sample stubs. Sonicating sample stubs in acetone and allowing them to air dry on filter paper before use is also a good idea, to remove anything like oil or other contaminants that may have gotten on them prior to use, then storing them in a container that will keep them from touching anything else until you're ready to use them. Also, while the duct tape for mounting your setup was probably the most convenient way to go at the time, I would avoid using that for mounting if at all possible. The residue left behind by the adhesive will get burnt off by the beam and have the same effect as the oil from your fingers.
A stepper motor on the stage control triggered by "frame complete" would be so cool......... oh you just said that as I was typing. The duration of the animations that you can get manually kind of reminds me of doing computer animation back in the 386/MS DOS days.
Great work, I am a few months away from retirement but around 20 years ago I did something similar with the head of an insect in an SEM. QuickTime VR had just been released so I took pictures of the insect every 10 degrees thru 360 degrees and at 5 degree tilt angle for 90 degrees. Fed the 2D array of images into Apples QuickTime VR object creator and bingo on the screen was an SEM image that you could manipulate with the hand cursor.
