Projects like this need to be their own sub-field of science. Work put into creating methods and designs for science to be done at simpler and cheaper levels is incredibly important and deserves more recognition.
it kinda is. its usually referred to as citizen science, or simply DIY lab gear. The trade off is repeatability, reliability, useability, resolution, etc. But that being said, not everyone that would like to make use of, say an atomic force microscope, needs a just push a button and go repeatability and resolution on the finest levels possible. We just need SOME level of repeatability and ease of use, that is relatively reliable. Even if that comes at needing to start with a datum every run to zero everything. The problem is labware is made for the complete other side of that equation. The research labs with grants and such. Places that dont think twice about buying a machine that is 6 or 7 digits, comes with an install crew, and optional construction of a new building to house it, and a weekly maintenance plan for 10 years, plus a 6 month course in how to use it for the lab techs. Yeah, citizen scientists dont need that. And they wont sell them to us at a reasonable price.....so we figure out how to hack our way around the problem. You should check out the laser scanners made from old dvd drives ;)
@@zombieregime That's pretty true but what I mean is that that type of science needs formal recognition and a subgroup of research teams with some funding. We should have proper papers coming out in the field and helping push for simplification as well as advancement in official ways.
High-quality project, low quality video. Im tired of these ai voiced and written videos. I think this is the first ive seen it on a video with this impressive of a project, and it breaks my heart in way i didnt expect
Wow. A functional STM from 3d printed parts and low-cost off the shelf components. Great project and thanks for sharing. As the saying goes, “What a time to be alive”!
As someone who has worked with stm i can guarantee you that your results are insanely good. The Maschine i worked on was a giant multi ton monster and the results were similar.
I’m absolutely blown away by what you’ve done here! Building a 3D-printed Scanning Tunneling Microscope that can literally see atoms from a home setup-this is the kind of thing that feels like science fiction, but you’ve made it real. This is pure genius! The creativity, the engineering, and the sheer determination it took to pull this off is nothing short of legendary. You didn’t just build something cool-you’ve pushed the boundaries of what we thought was possible with DIY science. It’s inspiring to see how your curiosity and persistence have led to such a groundbreaking achievement. You’ve set a whole new standard for what’s achievable with passion and ingenuity. I’m genuinely excited to see what comes next-this is the future, and you’re leading the way!
Pretty cool what you did! About 20 years ago I did interns and later worked on the microscope department of the University of Leiden and later TU-Delft in the Netherlands. I have played around with the portable STM to get familiar with the matter and after that did a big project of overhauling and modifying an experimental Variable-Temperature-STM. They have made lots of scientific research with publications with my microscope. Later on I designed probe holders for some more years for Transfer-Electron-Microscopes. But chose an other path in life. Still your video journey brings me back every step I made back then.
I literally added this to favorites as soon as I saw the thumbnail. We've come to an age in manufacturing and information where brilliant people like you can build what would take universities many months and funding. Congrats !
at our institute we sometimes created the tips using a chemical etching process with a current flow detection to immediatly retract the tip when etching is done
Finally a new real good science channel. About the tungsten wire, you can sharpen it with a lighter, I think "the thought emporium" did it to replicate gecko tape. Incredible work, can't wait to see your next projects
Hey, at least you live close enough to BART for it to be convenient for everything except operating an STM in your living room! This is great, thanks for sharing it. It showed up on my home page, so the algorithm seems to be smiling upon you. I hope this video gets the views it deserves!
“3D printing a STM was harder then expected” I kinda find that a wild statement to make. I find it insane you succeed at all. Honored to be your 4 subscriber. Why didn’t you use gold for the tip? gold welds at normal conditions so it’s great for creating nano wires, not that I know if it’s actually good for this use case, but I’ve done quantum conductance experiments with it.
Glad you like it! Re STM tip material: Gold is very stable but it is too soft and cannot form a sharp tip point. Pt alloy is a better material due to its similar stability and often used in ambient STM. Unfortunately it is too expensive and outside my budget...
I was like, you're the 4th subscriber? then I checked how many subs he has, he has like not even 300 subscribers? I am shocked this really doesn't feel like something a small channel would do (I subscribed BTW this is epic)
Incredible project. Is that your first ever RUclips video? Your filming and video editing skills are top notch. I look forward to your future videos and witnessing your success on RUclips
"building an stm with 3d printed parts was harder than i expected."..no fucking shit. who would have thought. amazing work though, very hopeful there will be more content on this channel. cheers
This is so beautiful and well documented. I love it when i See people build on what others have learned or done. And this video? Sweet quality and a touch of humour 😊 SUBBED 🎉
The channel "Breaking Taps" created a tungsten wire electrode with a fine point via a chemical etching process. This is discussed at the timestamp 13:50 in a video about creating a camera sensor (not directly included to avoid the comment getting nommed). Hopefully this is helpful and helps with the reliability issue!
@@Wackylemon64 Cut PtIr wire works pretty well in air because PtIr does not oxidize. You can etch PtIr, but it is more difficult because gas bubbles form on both the PtIr and the other electrode, so the nice tip formation that happens with tungsten does not happen as easily with PtIr.
I love it ! Wondered for a while if that was possible and you proved it in the best possible way ! Well done, you did such a nice work ! It opens a lot of possibilites :D
Ive only watched the first 2 miniues of your video and i wanna congratulate for explaing how tunnellung microspoce works in such clever and easy to understand way, much better than 4 of proffesors at my univeristy. They all use some 144p schematic image and pretend its so complicated that we probably cannot understand it so why even bother... Now i can watch the rest, thank you for your work.
Amazing project and video! I didn't think it would be possible to get something this good with just 3D-printed parts. I think the tip is probably a major thing holding it back, there is a nice article and video on the "Zyrus Etcher" which might be a good fit for this project.
Normal engineer: "I used a short segment of RG-316, since I didn't want to add potential variables to the project" An absolute chad: "I made a miniature coaxial cable [since I had the copper tape handy]"
This is wonderful. I've never ever tought it's possible to diy such equipment! As somebody who works with AFM on a daily basis, I can assure you that most of the scans on actual scientific equipment are comparable in quality to yours. Btw, feel free to contact me if you want to get some samples scanned with scientific equipment.
Very cool result. How did you calibrate the magnification? Sometimes it can look like you're imaging individual atoms with STM, but what you're actually observing is a much larger scale moire pattern caused by a slight misalignment between the carbon layers in the graphite.
Epic. I have some plans to build a scanning electron microscope at home, but with a bit of a twist from a normal one. Just have hard finding time with children in the house :D
if you want to understand the cost associated with laboratory precision instruments.... here is a little anecdote. i once tried to price a *used* 600mhz NMR. the dewer/primary superconducting magnet assembly (the most "immediate" visually identifiable part) - $3,000 the air assisted spinning sample probe - $1500 the supeerconductive RF pickup/probe - $1500 the "NMR cabinet" (other names exist), which looks like a generic "box of electronics", usually standalone (to mount it far from the NMR and the pesky human user ) $80,000 its ALWAYS the electronics, with the software/control sometimes 2nd
hey, I feel bad bringing up the AI voice because you just built the most insane diy projects I have ever watch, and that is infinitely more deserving of attention than the voice, and I also see you did it because english isn't your native language which is fine for me... but the voice is a bit off-putting. I really hope this doesn't hinder your visibility, because again - the project is insane and I'm amazed you got something working in the end ! I subscribed snd am definitely looking forward to what'll be next :)
I think to make the needle you're supposed to strongly pull the wire so that it tears (also try annealed copper wire). Steel springs aren't that dampening, they're used in analog audio reverbs. Try rubber strips. Also I remember that burning a graphite rod with electric current creates a supersharp needles. But carbon has hexagonal molecules so that's a problem..but it's easy to do, so worth trying.
You can add additional vibration isolation by adding a more plates with viton o-rings in between on the base on the springs. Other fun air stable systems you can scan include MoS2 and TaS2 (though this one will slowly degrade in air after fresh cleaving).
Большое спасибо за видео! Это именно тот контент, которого мне не хватает в RUclips. Хотелось бы видеть масштаб на изображениях. Я думаю, это нетрудно сделать, когда для движения используются шаговые двигатели.
Stepper motor is only used for Z positioning. XY movement is all from the piezo actuator. Unfortunately, i don't think stepper platform is viable, a single step off a stepper will be much larger than the scanning field. So stepper couldn't be used to calibrate the piezo movement.
Incredible project! You tried with many carbon samples, but there are some restrictions over the materials that you could use? Also, what would be some things that you'd like to try in the future over this STM?
Very cool project. At first, the video it felt like one of thousands 'let me read the Wikipedia article out loud, but pretend I've invented it'. This is likely due to the use of the AI voice? The STM looks great, and I'm looking forward to seeing your design files and publication. I would have the repository with these files linked AND live at the same time as the video, though. This greatly increases the interaction with your audience. For example, I have to remember to get back to this video in the future to observe if the files are releases yet. I'm likely not going to build one, but I just want to play with the files and learn a bit more about your construction.
@@andyburns He has also another channel and that one is in Mandarin with English hardsubs, and an occasional video where he speaks English and is struggling a fair bit.
I, too, love the project, hate the AI voice. I'd rather listen to a heavy accent, speech impediment, untrained voice, anything with soul. Good job on the project, tho, this is incredible! Amazing how people here on RUclips are making STMs and semiconductor devices in their home labs!
I'm also conflicted on this point - I am uncomfortable consuming media made with AI, but this creator has accomplished something astounding, and to complain about the voice seems like such a quibble. I end up reasoning that this is one of the good things that these new AI systems can accomplish, unfettering the transfer of knowledge. I will be honest, I didn't detect that the voice was AI until it put a comma in between "scan" and "head" at 9:35. I might have assumed that this was a brilliant inventor with a radio voice, who was probably handsome as well. 'Better not let my wife see this,' my caveman brain says. 'this guy is obviously pretty good genetic material and probably has access to resources as well'.
@@Jerguu AI voices make me question the legitimacy of a video and whether it is or is not stolen content. Given this is the only video on the account, I suspect it is not their content.
@@AnaphylaxisMan Why is machine voice a problem for you? Ethical constraints like unlicensed material are not a problem with TTS API, since the voices are licensed from voice actors. It is also really a rather small network which doesn't consume substantial electrical power or material. It is not similar to generative AI as used for bulk text generation or image generation.
@@SianaGearzThat's good. That makes me feel better. I did a little bit of searching to see what this is all about turns up multiple TTS APIs, is there a standard one that I'm not aware of?
It‘s amazing how you managed to build one at home using 3D printed materials and getting such great images and atomic resolution! How much did the materials cost you?
The electromagnetic damper seems like it would feed the BART's vibration back into the platform thanks to induction. Also, a question: When you ground the copper shielding... don't you vice versa feed all the noise from everything else attached to your house's ground (computer, AC, fridge, you name it) into the system?
would placing the STM in a temperature controlled 'oven' be a good way to deal with thermal expansion issues? Maybe at ~30degC for instance (above room temperature). That way HVAC / room variation doesn't affect things.
This is absolutely unreal! Using Eddy current as a damper is simply brilliant. Are the sampling and control rates needed that high to require the PI? Also, where are the files? I need to make one! WOW!
There is no Pi here, instead a Teensy. I can't say that a very high performance controller is required, after all the C&C is via 115k serial, nothing is really fast here. At least i'm not really seeing anything. But sometimes you just use something because the ecosystem is that good you know? Like you have all the libraries and tools and they're high quality and they work. PJRC is so good in this regard.
i wanted to express my appreciation but i haven't found suitable words to do so honestly. Therefore i'll ask instead how long it took you from idea to creation of this beast?
@@MechPanda-tt2gb Well i heard you speak English on another channel and found it satisfactory. People care about authenticity for some reason 🤷♀ I think people underestimate the difficulty of recording a good voice-over.
Could you please update your video description to include the links to the reference blog you mention as well as the links to your open sourced design data?

Hopefully this is helpful and helps with the reliability issue!
The short of it, is to apply a voltage to the tungsten wire, the tip dipped in a solution of potassium hydroxide, to electrochemically etch it
Tungsten tips oxidize in air, you can only reliably use tungsten etched tips in an ultra high vacuum.
@@BairdBanko What form factor for the tungsten tip would work best in the context of this STM? Is the "wedge" the only conformation which works, here?
@@Wackylemon64 Cut PtIr wire works pretty well in air because PtIr does not oxidize. You can etch PtIr, but it is more difficult because gas bubbles form on both the PtIr and the other electrode, so the nice tip formation that happens with tungsten does not happen as easily with PtIr.
You can do this by buying the stuff at any welding store - it's chemical sharpening of tungsten electrodes.

Incredible work! I really like this side of RUclips.
I'm impressed. Learned a lot too.
Great project! Regarding the tips try to look into electrochemical etching to get a sharp tip pretty consistently
Yes, I was wondering if that would be a better approach. I know it gets used for TIG, but don’t know how well it would work for STM tips.
Vraiment impressionnant ! Bravo 👏

I can't say that a very high performance controller is required, after all the C&C is via 115k serial, nothing is really fast here. At least i'm not really seeing anything.
But sometimes you just use something because the ecosystem is that good you know? Like you have all the libraries and tools and they're high quality and they work. PJRC is so good in this regard.
Won't the dampers feed vibration back into the pendulum? Any vibration induces a current and force into the platform.
@@2xKTfc The current is dissipated by the resistance of the metal to heat.
For creating a sharp tip, what if you used a highly conductive needle? the tips are hollow but I think fine medical ones might be useful
the piezo actuators could be used to move a laser dot very precisely over a long distance, maybe to project an image using a mirror on the piezo ?
Gotta make a discord for all the stm bros
Brilliant.
i wanted to express my appreciation but i haven't found suitable words to do so honestly. Therefore i'll ask instead how long it took you from idea to creation of this beast?
Great video! I am in the process of building my own. Where did you source the HOPG, and what did you pay?
I bought it from eBay for around $40
Amazing project! Did you use text to speach for the voice over?
Yes (English is not my mother tongue so I think using generated voice is more clear...
@@MechPanda-tt2gb Well i heard you speak English on another channel and found it satisfactory. People care about authenticity for some reason 🤷♀
I think people underestimate the difficulty of recording a good voice-over.
Could you please update your video description to include the links to the reference blog you mention as well as the links to your open sourced design data?
Will do! RUclips does not allow me to link to external link for now....
Amazing project, but I would like to know why you chose a pid loop for the feedback system. I don't think it's a very good fit for this application
Ah yes i remember learning about magnetic induction in kindergarten
Bro think he Yakub the big headed scientist, and creator of the white man.
You can use Pt/Ir or Pt/Rh wire (85/15 or 90/10) and you won't damage your wire cutters.
I didn't find a reasonably priced Put alloy tip at that time 😂
