The vinyl record that I cut into sections was actually Johann Strauss (The "CBS Masterworks" label can be seen at 0:26). Switched-on Bach remains intact.
great work by the way - just thinking about having a 12" single with recordings on 45 rpm would have been a more spectacular insight as the grooves are in fact a lot bigger than on LP. but anyway some great insights here.
Around 1987 a good friend of mine had over 50 of the video discs and player. It actually played very well. Awesome to hear you explain how all of these various techs work. Thanks for a great video.
@@TheGreatGadfly There is a style thing to a return to vinyl, but it's nearly the closest we have to actually capturing the full color of sound. Maybe magnetic tape as well. Even high bitrate, lossless digitizing doesn't capture it completely. Think that doesn't matter? Tell that to a person who can tell the difference between violins, or pianos or cymbals of a drum set. I can assure you there's an appreciable difference.
@@ChuckD59 It does capture it completely, denying that it does is denying math is real. Any difference you hear between lossless audio and vinyl is a discoloration or distortion introduced by an imperfect player or record.
@@lobsterbark Wow. I know "math" and I know music as a classically trained musician, and I know a bit about computers (actually a lot). I have to respond saying if you claim a digital reproduction captures all the nuance of an analog source, you may not know what "digital" means. Higher bitrate/depth reproduction come close, but the very definition of "digital" is ones and zeros.
@@powertotherobots0 I know, right? I understood every bit of it. The average US adult has a lower math education than the average 8 year old Korean child.
It is mind blowing if you think about it. Any sound, from trumpet, to bird, to glass breaking, (x's infinity) can be etched in vinyl and re-played perfectly. Even a thousand people,saying the exact same words, can be differentiated by tone and timbre. An entire orchestra can be duplicated in one groove. I don't understand it.
It's all related to the property of superposition in waves. And I'm not talking about Quantum Mechanics here, it's just the fact that if you have 2 waves, and you add them together, you get a new wave with a different shape, which in the case of sound would sound like the two original waves together. Now to actually be able to create these grooves, that takes a bit more mathematics. That uses a thing called the Fourier Transform, which is a mathematical operation which "picks out" frequencies. It basically multiplies the original signal/function with a pure sine wave at a specific frequency, and then adds up the entire function (integration), so see "how much" the original signal "resembles" that specific wave with that specific frequency. And then it repeats that for every single frequency to get a "frequency spectrum". So if you record a sound, you can convert that to frequencies, which you can then convert back to grooves by adding up waves with all the frequencies you found.
One way I can wrap my head around it is if you cut out the tiniest blip of an audio clip in a software like Audacity or any DAW, then played that blip back, it would just sound like a tiny click because it's so quick. It's only when those clicks are not surrounded by silence but the context of other "blips" that make it sound like anything.
There's more to it than this, but this is Step 1: Needle in groove. It's tiny, but physical, which is why decent equipment and care of your records is vital.
Holy crap. Let’s take a minute and compliment how well this was done. This is pretty amazing. The way you figured out each type of disk and the way you made the amazing video of the plastic phono record. Super well done! Bravo.
apparently a quick google search revealed they can cost something like up to $1,000,000 in dollars. Not something I'd ever get as a birthday gift, let's put it that way.
@@kennarajora6532 not this one. He got it for free and just had to pay shipping. It's an older model anyway so could probably be picked up on ebay for under 10k. Still not cheap but not terrible for the capability.
@@unpluggedtoaster7421they dont use vibrations in the way they did in the early days, as in recording into a horn and letting the vibrations from the sound vibrate the diaphragm and thus the needle. they use massive record cutters that use electronics to make master discs and then stamp all the records using that master.
The field created by the current of a recorded signal moves magnets mounted on a stylus, pretty much the opposite of a phono cartridge, cutting the signal into a lacquer disk, eventually ending up as a stamper pressed into a hot vinyl "biscuit". Sure it took some work, getting everything to function correctly. But, basically it just replied on physics. The magnet field is an accurate representation of the current that creates it, and a magnet will accurately represent the change in field strength, if that makes sense.
I cannot believe all of the hurdles that you had to go through to be able too do your video. You have incredible problem solving skills.I would not be able to do something like this because of all the different steps that you had to solve. So many problems to be solved that created new hurdles. I really admired that you showed how you were able to get the amazing image's. Without that information you would not understand the difficulties and problem solving that went into creating this video.
people mostly think they CANT, when they CAN, if they pay attention to simple things like thermodynamics, expansion and contraction. The most basic, yet observable laws of physics.
I meant that (more precisely) that it is simply not intelligence or idiocy but the depth and density of thought. Maybe some people just do not have the energy.
One of these days this guy will upload a video in which he talks about how he had to use his nuclear reactor to turn toothpaste into gold because his particle accelerator still needed some work.
multi io dude he's gonna make a tutorial for how to create a fusion reactor. "Now, I'm still trying to get a working heat shield, currently mine is lacking the needed materials as of now because they don't exist, so I had to use multiple electromagnets to try and prevent it from melting itself."
Amazing video! I would have given up at the beginning when I realized that the record was an insulator. A great example of how far a person's curiosity can go. Respect!
"My sputter coder needs some work so I'm using physical vapor deposition" Yeah, me too bro... Edit: numerous replies have corrected me, it's "coater" not "coder"

So i started writing a comment about 5 times before I realised that I actually have very little in the way of words to describe the satisfaction I got from your video. So i just liked and subscribed and wrote this instead. Thanks man.
You can often find used ones one eBay (usually in pieces and you'll probably need to buy a few more parts), many of them functional anywhere from $500 USD to $100,000 USD. With enough knowledge and skill I bet you could get one functional in your home for $1000 (maybe less).
The device itself is really not as complex as you think at the basic level. It just becomes exponentially more complex as the image quality/res you want increases. I mean, think about it this way: the electron beam part of the microscope is just an advanced version of an old TV CRT. The sensor and the electronics that interpret the signal are probably the most complex parts (unless you're using some super-vacuum pump or something).
I love the way you end this video. You just explained and showed something way over most peoples head and then you just simply say, "Okay, see ya next time."
"OK, see you next time.".... ya frickin' genius. "What did I do last weekend? Oh, nothing much, just imaged some storage media with my electron microscope." O.O

butter vapor is something i never considered, i guess that with a vacuum chamber, some high heat and a very fine butter spraying device you could coat your croissant. now im wondering if all the air in the croissant is going to escape making it look like a balloon under a vacuum. this is what keeps me awake at night, deflating croissants

The CVD is a common technique in material coating. It usually involves fusing with the substrate and making the coating part of it instead of just a layer on top.

In a CD/DVD/Blu-Ray, the data information is molded into one side of the polycarbonate substrate. The aluminum, silver or gold metallization is used mainly to reflect the three lasers (two tracking, one data) as they go thru the smooth polycarbonate side, then bounce off the metallized data side, and back to the laser heads. The lacquer coatings are purely for protection of the data side of the polycarbonate. Your method of tearing the aluminum is giving you only an embossed image copy of the data that is imprinted in the polycarbonate substrate. Retired Media, Manufacturing Engineer and Equipment Designer for Technicolor.
What is really interesting is that all of the Media he tested is Stamped or Pressed. A Gold of Nickel coated master plate is made, From this a negative image is made, and then used to make positive duplicates in a press. This is called surface replication. The Replicated surfaces, depending on how it will be read, might need a reflective and or protective coating.
Cool, a lady yelled at me and got herself fired at Technicolor. Not going to go into detail on that one lol. Funny thing is i learned what you just said, not from technicolor, but from researching playstation 2 discs and trying to figure out why they were black when I was a kid lol.
I didn't even know it was possible. I'm going to have to buy some random terrible (but still dual-layer) movie that I don't care about down at the thift shop and see if I can scalpel that apart the same way. Make a couple of conversation-piece coasters out of it.
the one thing i know i will never fully comprehend is how grooves in a record can actually produce complex sounds. that's always going to be witchcraft to me.
Calvin Lee The groove walls oscillate exactly as the sound wave compresses-expands the air, so all you have to do is amplify the signal (well there's an "RIAA equalization" to the sound because the vinyl medium is better at capturing some frequencies than others). It's an elaboration of the earlier gramophone and Edison cylinders in which the oscillating needle is simply connected to a horn, no electronics. What is impressive is how good such a crude method can sound.

Nice to see the old SEM. I used to operate one of those when I was a lab assistant back in the 90s. Once I found a dead bee on the window sill and when nobody was looking I popped him in. I zoomed in on his eyelashes and discovered they were long, splined cones! Who would have thought? I also got a shot of his knees. I printed that one off and labelled it 'The bee's knees' - (obviously) Happy days. This video took me right back. Thanks.
Thank you for all the Bloody Details, for us tech junkies! Sir, you have successfully recreated in EXTREME miniature scale, almost EXACTLY the methods I used to create Traditional animation almost four decades past. The industry in the 70s (in Hollywood, New York, Europe, etc.) was using room-sized Camera stands aimed downward at an art stage with pins ("pegs") precisely matched to holes punched in the animators' paper and acetate sheets, to _register_ the art under a camera with carefully angled lighting. Some were gorgeous collections of exquisite interconnected slides, with smooth gearing and locking levers and scales, knurled knobs and pointers and post-it notes... I used 18"square polarizing filters mounted in front of the lamps, with small glass polarizing filter on a 25mm focal length lens. This suppressed glare and dust, And increased the saturation of the colors. The procedure was frame by frame, just as you were describing, especially for pans and zooms in a sequence. Expose one frame, change the art, move the background one increment, close the glass platen to press everything in place, then repeat those steps until you'd shot all the art, and positions for that sequence. An individual shot in a story, that might have a running time of a few seconds, might take eight hours just to SHOOT one or two sequences, after a hundred hours to create the art. Fun stuff. My little studio started with a fer-Pete's-sake 16mm Swiss Bolex on a hand-built stand. I started working with "hi-end" CGI 35 years ago. You'd like to think that stream-lined everything, wouldn't you? Ask me about doing individual PIXEL surgery on the art for a driving game at Atari...
That... Was... AWESOME! I am just now stumbling across this channel. This video is exactly what I was looking for every time I plugged the word "science" into the search bar.
I am speechless. You sir, have blown my mind with your novel approach to dissecting various media for the benefit of folks that would never come into contact with an Electron Microscope. For this I thank you ....awesome video.
Always assume that if someone owns a sputter coater , they are really smart . Knowing how to jimmy rig something else into a working version of a sputter coater ? ... priceless
I have one. They run the gamut on complexity (and thus price). The concept is pretty basic. Pull a vacuum, melt or evaporate material to where it is vaporized and is deposited on a part, usually some sort of sub-straight. Complexity/price go up dramatically depending on the vacuum needed, measured in negative atmospheres and size.
This was so fascinating, I sent the link to my artist/metallurgist wife. She almost went into anthropological art (the art of reassembling skeletons and stuff, whatever that field is) and I think she would find the mix of technology and art in this just as compelling. Great work!
***** Thanks! And thank Tek for sending me the oscilloscope. I've been planning to build a direct-to-computer digitizer for the SEM, but using the oscilloscope has been so convenient and adjustable, I'll probably continue with that for a while.
When my sputter coder was being serviced, rather than loading the slide into a vacuum chamber and evaporating silver metal onto the pieces of the LP... ... I interaxelated depolarized tri-polymer plasma into a recursion matrix, by way of a gas chromatograph mass spectrometer (with the promo-dynamic module set for differentially charged polaric ions), which left a quantum signature in the vinyl. This gave me zeta particle derivation compliance, and allowed for precise flow rate adjustments of positronic neural peptides.
Rinoa Super-Genius I didn't cut up Switched On Bach. I also bought a Johann Strauss LP and sliced that one into pieces. I saved the Bach disc because it seemed unusual.
Applied Science oh ok, i dont think it would have been a big deal if you did though. ^^ any ideas on how to visualize the magnetic sectors and stuff on floppy discs and hard drives? i would love to know if the magnetism alone alters the image at all.
Rinoa Super-Genius to see how magnetism alters a flying electron image, get a really strong magnet, even fridge magnets might work, and move it across the bottom of a crt (cathode ray tube, i.e. flying electron tube) screen - old school tv or computer monitor, non flatscreen, non lcd.. you know.. those big bulky ones.. on the computer monitor the degauss (vibrating magnetic field) should clean up the mess you leave behind on the screen with the magnet when you press the degauss button on the front control buttons.. it's residual magnetism you leave behind in the metal mesh that guides the electrons to the pixels on the screen.. the equation of the force of a magnetic field acting on a moving charge F=q.(v x B), where v x B is the cross product of the velocity v in meters per second and magnetic field flux density B i have to look up the units, found it, its webers, times the charge, in coulombs, and the interesting thing is that its a sideway force.. it requires the velocity of a charged particle going not along, but perpendicular to magnetic force lines, and then it gets pulled to the left or right, sideways, 90 degrees to both the magnetic field lines and the velocity vector.. so when an electron flies straight in vacuum, you put two poles of a magnet across each other, and it will get detered to the left or right depending on the orientation of north or south poles.. that is in fact the control used in crt screens, magnetic coils make the electron beam sweep across the screen at the refresh rate vertical Hz and horizontal kHz, while in oscilloscopes the usually greater depth requiring cannot make the screen so "tight" electric field is used (the electric field deters on a parabola, while a magnetic field on a circular path)
Sillybillydilly thanks for stating what i already knew when i was like 10, but your comment really has no relevance to the question of weather or not magnetically stored bits would distort the image in an electron microscope. or atleast i didnt see that in your comment.
Great to see someone making things, creating devices, solving problems and presenting all that as images. Good to be a human sometimes, and congratulations.
CED! I had an RCA Video Disc player back in the day. Great resolution, and fantastic audio, but dust gets in there so dropouts were a problem. For the time though, amazing. Double kudos for using Wendy Carlos for the vinyl GIF! I'll have spin that one today myself.
Fran Blanche I have a Pioneer Laserdisc player and some Discs. I mainly got it to watch Apollo 13. I must have watched in 50 times in one year back then. Now you know why I enjoyed your PCB teardown so much.
Fran Blanche I worked for RCA in that time and it was known that the playback stylus would damage the grooves and cause visual image hopping. The gamble was on the catalog. RCA had a much larger catalog then Pioneer and actually did quite well for a very short time. But it was a short lived item.
I took apart a cassette tape once and I was looking closely at it. And I told some one that you can see the words if you look close enough. It fooled a couple of people. lol

I still can't get over the fact that you made your own sputter coater, not to mention everything else you did. That's genius level creating. You'd have to have a PHD level of understanding in the various sciences used in this video. Hat's off to you and thanks for your video.
Most people are listening to digital files or streaming these days but records are still fascinating even for new millennials I think. They are pretty close to magic. Thanks for you work!
Mok214 Me too! I've been really interested in seeing stop motion and also realtime video from a SEM. I've got some projects on the way to show more of this.
Applied Science It was really beautiful to watch. Looking forward to watch 3.5" Floppy and specially the MO Disc. I wonder if it would be possible to see helical scan patterns of VHS tape.
Ali Mirjamali In the early days of videotape editing , we used Edivue tape "developer" on 2 inch quad videotape to see the tracks. The developer was a suspension of carbonyl iron particles in carbon tetrachloride. With a Smith splicer, you used a microscope to align and trim the ends before applying splicing tape. The tape ends had to be trimmed so that the splice was made just after vertical sync. There was always some disturbance on playback. Luckily they invented electronic editing after a few years.
Ali Mirjamali I haven't actually tried to view magnetic media in the SEM yet. The MO disk and floppies are for another project. But I can't believe I didn't realize that the magnetic areas would interfere with the beam in such a way that the information would be visible. I'll bet it will work! Thanks!
Not only were the video results fascinating, but your explanations of how these LPs & storage disks work were interesting. Yet your problem-solving processes were best of all! Well done sir.
+sinephase Just an educated guess, perhaps its background groves that can be read by waves in a particular phase which allows them to snake around/avert the foreground groves. I could be completely wrong.
Having caught up to this video, I would say that anybody who can build an electron microscope in his garage is fully capable recreating the lost works of Dr. Emmett Brown.
I made a time machine out of a train! Steam powered time travel! A refrigerator out of scrap parts! The flux Capacitor! The rocket powered drill! I love a good competition though!
I still find it fascinating that music can be produced by a needle wiggling up & down along one bumpy groove on a vinyl record. Especially when musical compositions and the different sounds of the instruments can be so diverse. I understand that it's all to do with either a negative or positive voltage changes as the needle vibrates, but it's still beyond me.
I'm the same. But think about what beautiful sounds you can make by dragging some horse hair across some thin strips of sheep's guts stuck onto a wooden box. Did I say "Stradivarius"?
Its not that far out. you can see it in action in an audio editing ap. when you play 2 sounds together their waveforms mix. music, and really all sound we hear every day, can be represented by this mixed waveform. a record is simply a physical copy of that waveform produced by an etching needle on a record lathe and pressed into vinyl.
Thanks for a genuinely fascinating video. Not only were the micrographs fascinating in themselves, the way you solved the various problems you encountered in creating them was brilliant. You are a very clever man!
I worked in a mastering lab and we had a 100x microscope which was sufficient magnification to check the groove. Notice no plural, there is only one long groove. Anyway, you are correct about the stereo channels and the needle moving side to side depending on the dynamic range of the sound, the mastering engineer would have to make sure that the channels were properly balanced or the needle would actually jump right out of the groove. the best engineer could maintain both tracking and high dynamic range, really an art.... saw lots of lacquer masters trashed by one channel too hot and the needle jump, that's why the microscope was better than an oscilloscope, which we also had.
Honestly - you are a hero. We'd still be living in mud huts without people of your ilk.... Thank you for this. I think it's phenomenal what quality of sound can be got from a groove in a disc of vinyl!
Fascinating. I get how digital tech today works and am unimpressed from an engineering standpoint, however, I find it amazing that something as seemingly simple as a record was ever brought to life. (By "unimpressed" I mean anyone can do it with the right tools/programing and easily build upon the premise. How anyone ever got microscopic grooves to record/create sound is mind-boggling hands-on mechanical engineering )
Your cognitive dissonance on these subjects is mind-boggling. What does "anyone can do it" even mean in this context? If we're comparing the invention of the record to the invention of digital technology.... no, not 'just anyone' can do either of these things and the comparison makes no sense. I'm unimpressed, and being unimpressed makes me feel so smart!
Originally "Switched-On Bach" was attributed to Walter Carlos who was actually a woman, Wendy Carlos, but record executives believed that no one would buy this album if people thought a woman had created it. Reality was acknowledged in the CD release. That aside, this was a fascinating look at our media and how they actually reproduce light and sound. Thank you. Subscribed.
Old comment I know, but needs a correction. Walter Carlos _was_ actually a man ... but he had a sex-change in 1972 (5 years after recording this album). This was pretty well known at the time, I certainly knew about it in the 80s before the CD-release. It's one of my first LPs and still gets played occasionally. You might notice the LP-cover of Switched-on-Bach doesn't say Walter or Wendy Carlos, the first line is "Trans-Electronic Music productions" , I don't think that's coincidence. ;)
@@njones420 Thank you for that. As I have both the original LP and the CD, I will check it out. More than that I will see if Wendy ever wrote a autobiography. I think it would be fascinating. She changed how the world heard classical music.
@@curtisrodriguez938 I'm sure there's a lot more to the story. I have no idea what the views were in the 60s/70s, but I did read she was having to wear fake side-burns etc for interviews and appearances. There must be a documentary somewhere... Sorry if that first comment sounded snarky, it wasn't meant to, but I just read it again :)
@@njones420 No worries on the snark account. It did not come off to me like that. The back of the album cover of "Switched-on Bach," at the top left corner it says, "Electronic Realizations and Performances by Walter Carlos with the assistance of Benjamin Folkman. There was no mistaking that the label was holding out the performer as a man. The CD notes indicated that the label was reluctant to credit a woman because people would not buy it. When I first saw the CD, I thought that either Walter underwent a profound change, a sex change. But after reading the CD notes, I understood them to say that Carlos was always a woman. The attitudes about women not being commercially viable has been a factor in the entertainment business for decades. One of the Star Trek writers was D.C. Fontana, a woman. Even today I wonder why the Harry Potter books were credited to J.K. Rowllng. I was around in the 1960's and 1970's. Sex changes were rarely written about and were not part of normal cultural interactions. The movie "Myra Breckenridge" was one movie about a transexual. It was a very different world.
@@njones420 You are correct. Wendy Carlos was indeed born a man who transitioned to a woman. The record label did not note the change for marketing reasons. I never saw any interviews with Wendy before or after her transition. Apparently she wore fake sideburns when she met Stanley Kubrick (She did the soundtrack for "The Shining.").

And I'm not talking about Quantum Mechanics here, it's just the fact that if you have 2 waves, and you add them together, you get a new wave with a different shape, which in the case of sound would sound like the two original waves together.
Now to actually be able to create these grooves, that takes a bit more mathematics.
That uses a thing called the Fourier Transform, which is a mathematical operation which "picks out" frequencies.
It basically multiplies the original signal/function with a pure sine wave at a specific frequency, and then adds up the entire function (integration), so see "how much" the original signal "resembles" that specific wave with that specific frequency.
And then it repeats that for every single frequency to get a "frequency spectrum".
So if you record a sound, you can convert that to frequencies, which you can then convert back to grooves by adding up waves with all the frequencies you found.
One way I can wrap my head around it is if you cut out the tiniest blip of an audio clip in a software like Audacity or any DAW, then played that blip back, it would just sound like a tiny click because it's so quick. It's only when those clicks are not surrounded by silence but the context of other "blips" that make it sound like anything.
We all live in one big vibrated field of energy, we are all instruments of the cosmos!
No matter how many instruments in the record, it's still one wave.

This is incredible. So many times we take small things for granted. How on earth they cut they grooves with accuracy back in the day is beyond me.
The way it was invented was by recording with the vibrations that then kind of create the grooves but idk if that's how they do it now
they molded it to like some sort of master vinyl tihng
@@unpluggedtoaster7421they dont use vibrations in the way they did in the early days, as in recording into a horn and letting the vibrations from the sound vibrate the diaphragm and thus the needle. they use massive record cutters that use electronics to make master discs and then stamp all the records using that master.
The field created by the current of a recorded signal moves magnets mounted on a stylus, pretty much the opposite of a phono cartridge, cutting the signal into a lacquer disk, eventually ending up as a stamper pressed into a hot vinyl "biscuit". Sure it took some work, getting everything to function correctly. But, basically it just replied on physics. The magnet field is an accurate representation of the current that creates it, and a magnet will accurately represent the change in field strength, if that makes sense.
I used to cut my vinyl with a hammer and chisel..
I cannot believe all of the hurdles that you had to go through to be able too do your video.

You can often find used ones one eBay (usually in pieces and you'll probably need to buy a few more parts), many of them functional anywhere from $500 USD to $100,000 USD. With enough knowledge and skill I bet you could get one functional in your home for $1000 (maybe less).
The device itself is really not as complex as you think at the basic level. It just becomes exponentially more complex as the image quality/res you want increases. I mean, think about it this way: the electron beam part of the microscope is just an advanced version of an old TV CRT. The sensor and the electronics that interpret the signal are probably the most complex parts (unless you're using some super-vacuum pump or something).

In a CD/DVD/Blu-Ray, the data information is molded into one side of the polycarbonate substrate. The aluminum, silver or gold metallization is used mainly to reflect the three lasers (two tracking, one data) as they go thru the smooth polycarbonate side, then bounce off the metallized data side, and back to the laser heads. The lacquer coatings are purely for protection of the data side of the polycarbonate. Your method of tearing the aluminum is giving you only an embossed image copy of the data that is imprinted in the polycarbonate substrate.

Calvin Lee The groove walls oscillate exactly as the sound wave compresses-expands the air, so all you have to do is amplify the signal (well there's an "RIAA equalization" to the sound because the vinyl medium is better at capturing some frequencies than others). It's an elaboration of the earlier gramophone and Edison cylinders in which the oscillating needle is simply connected to a horn, no electronics.
What is impressive is how good such a crude method can sound.

Sir, you have successfully recreated in EXTREME miniature scale, almost EXACTLY the methods I used to create Traditional animation almost four decades past. The industry in the 70s (in Hollywood, New York, Europe, etc.) was using room-sized Camera stands aimed downward at an art stage with pins ("pegs") precisely matched to holes punched in the animators' paper and acetate sheets, to _register_ the art under a camera with carefully angled lighting. Some were gorgeous collections of exquisite interconnected slides, with smooth gearing and locking levers and scales, knurled knobs and pointers and post-it notes...
I used 18"square polarizing filters mounted in front of the lamps, with small glass polarizing filter on a 25mm focal length lens. This suppressed glare and dust, And increased the saturation of the colors.
The procedure was frame by frame, just as you were describing, especially for pans and zooms in a sequence. Expose one frame, change the art, move the background one increment, close the glass platen to press everything in place, then repeat those steps until you'd shot all the art, and positions for that sequence. An individual shot in a story, that might have a running time of a few seconds, might take eight hours just to SHOOT one or two sequences, after a hundred hours to create the art. Fun stuff. My little studio started with a fer-Pete's-sake 16mm Swiss Bolex on a hand-built stand.

I have one. They run the gamut on complexity (and thus price). The concept is pretty basic. Pull a vacuum, melt or evaporate material to where it is vaporized and is deposited on a part, usually some sort of sub-straight. Complexity/price go up dramatically depending on the vacuum needed, measured in negative atmospheres and size.

When my sputter coder was being serviced, rather than loading the slide into a vacuum chamber and evaporating silver metal onto the pieces of the LP...
... I interaxelated depolarized tri-polymer plasma into a recursion matrix, by way of a gas chromatograph mass spectrometer (with the promo-dynamic module set for differentially charged polaric ions), which left a quantum signature in the vinyl.
This gave me zeta particle derivation compliance, and allowed for precise flow rate adjustments of positronic neural peptides.

oh ok, i dont think it would have been a big deal if you did though. ^^
any ideas on how to visualize the magnetic sectors and stuff on floppy discs and hard drives? i would love to know if the magnetism alone alters the image at all.
Rinoa Super-Genius I love that Switched on Bach album. I used to listen to it as a kid.
Rinoa Super-Genius to see how magnetism alters a flying electron image, get a really strong magnet, even fridge magnets might work, and move it across the bottom of a crt (cathode ray tube, i.e. flying electron tube) screen - old school tv or computer monitor, non flatscreen, non lcd.. you know.. those big bulky ones.. on the computer monitor the degauss (vibrating magnetic field) should clean up the mess you leave behind on the screen with the magnet when you press the degauss button on the front control buttons.. it's residual magnetism you leave behind in the metal mesh that guides the electrons to the pixels on the screen.. the equation of the force of a magnetic field acting on a moving charge F=q.(v x B), where v x B is the cross product of the velocity v in meters per second and magnetic field flux density B i have to look up the units, found it, its webers, times the charge, in coulombs, and the interesting thing is that its a sideway force.. it requires the velocity of a charged particle going not along, but perpendicular to magnetic force lines, and then it gets pulled to the left or right, sideways, 90 degrees to both the magnetic field lines and the velocity vector.. so when an electron flies straight in vacuum, you put two poles of a magnet across each other, and it will get detered to the left or right depending on the orientation of north or south poles.. that is in fact the control used in crt screens, magnetic coils make the electron beam sweep across the screen at the refresh rate vertical Hz and horizontal kHz, while in oscilloscopes the usually greater depth requiring cannot make the screen so "tight" electric field is used (the electric field deters on a parabola, while a magnetic field on a circular path)
Sillybillydilly thanks for stating what i already knew when i was like 10, but your comment really has no relevance to the question of weather or not magnetically stored bits would distort the image in an electron microscope. or atleast i didnt see that in your comment.

The tape ends had to be trimmed so that the splice was made just after vertical sync. There was always some disturbance on playback. Luckily they invented electronic editing after a few years.
Ali Mirjamali I haven't actually tried to view magnetic media in the SEM yet. The MO disk and floppies are for another project. But I can't believe I didn't realize that the magnetic areas would interfere with the beam in such a way that the information would be visible. I'll bet it will work! Thanks!
Anvilshock That's a good point. Having true high-speed SEM video would be incredibly useful!
This guy just Tony Stark'd the shit outta this!
Andy Hale Stark is fake as fuck
Not only were the video results fascinating, but your explanations of how these LPs & storage disks work were interesting. Yet your problem-solving processes were best of all! Well done sir.
I'd like to see an even closer look at those grooves. It's amazing what magnification and resolution can reveal.
Bluray, of course, would require an even crazier res electron microscope. I imagine it appearing similar to the cd and dvd examples, just tighter.
what I want to know is how multilayer works :P
+sinephase Just an educated guess, perhaps its background groves that can be read by waves in a particular phase which allows them to snake around/avert the foreground groves. I could be completely wrong.
Isn't Blu-ray dual layer?
Some are, yes.
Some are even triple layer. And supposedly there could be quad layer, though none have ever been made commercially available.
Man that was cool, you answered so many questions I’ve had about all of that! Thank you sir!
It Has Been Written :
Oh man that is too funny. Fabulous comment
Brian W now is that funny
Thank you. Being involved in engineering for over 40 years I immensely enjoyed that. Great job!!!
Having caught up to this video, I would say that anybody who can build an electron microscope in his garage is fully capable recreating the lost works of Dr. Emmett Brown.
I made a time machine out of a train! Steam powered time travel! A refrigerator out of scrap parts! The flux Capacitor! The rocket powered drill! I love a good competition though!
There's something about used needles that just doesn't sit well with me
wise guy :)
AIDS?
I know man, the needle gets clogged and the cocaine barely gets through.
I still find it fascinating that music can be produced by a needle wiggling up & down along one bumpy groove on a vinyl record.
Especially when musical compositions and the different sounds of the instruments can be so diverse.
I understand that it's all to do with either a negative or positive voltage changes as the needle vibrates, but it's still beyond me.
I'm the same. But think about what beautiful sounds you can make by dragging some horse hair across some thin strips of sheep's guts stuck onto a wooden box. Did I say "Stradivarius"?
I'm hip... boggles the mind
Its not that far out. you can see it in action in an audio editing ap. when you play 2 sounds together their waveforms mix. music, and really all sound we hear every day, can be represented by this mixed waveform. a record is simply a physical copy of that waveform produced by an etching needle on a record lathe and pressed into vinyl.
Its the same as how a microphone works, its "recording" the grooves' waves instead of air pressure waves
@Spike Flea this channel is called "applied science". Taking the mystery and intrigue out of things is sort of the point of science. Haha
Thanks for a genuinely fascinating video. Not only were the micrographs fascinating in themselves, the way you solved the various problems you encountered in creating them was brilliant. You are a very clever man!
Records may not be sophisticated technology, but they are actually damned ingenious. Thanks Mr. Edison and Mr. Bell.
Fuck Edison. Now we know he was an asshole. Humanity would of been better served by Tesla.
"okay, see you, bye!" - how all youtube videos should end! (and some should start)
I worked in a mastering lab and we had a 100x microscope which was sufficient magnification to check the groove. Notice no plural, there is only one long groove. Anyway, you are correct about the stereo channels and the needle moving side to side depending on the dynamic range of the sound, the mastering engineer would have to make sure that the channels were properly balanced or the needle would actually jump right out of the groove. the best engineer could maintain both tracking and high dynamic range, really an art.... saw lots of lacquer masters trashed by one channel too hot and the needle jump, that's why the microscope was better than an oscilloscope, which we also had.
A porky prime cut! Actually Porky (George Peckham) could do more than one groove on a side...
It is a good trivia question. correct answer is 2, one either side of a record.
Wow the sheer dedication and expertise this guy has in order to make this work
Wow, 40 years later, I finally know how it looks like and how it transmits to audio.
Listening to him talk is what reading a book whilst being illiterate must be like.
I bet you feel like a real genius for using whilst.
@@phlog_dog7336 When your name is Fabrizio you have to say whilst at least 5 times daily.
This is so cool!! I'm in my first TEM class and I can't believe what you're saying made sense to me! I guess my tuition is really worth it lol
You're the only one in this comment section to say that!
Honestly - you are a hero. We'd still be living in mud huts without people of your ilk.... Thank you for this. I think it's phenomenal what quality of sound can be got from a groove in a disc of vinyl!
Fascinating. I get how digital tech today works and am unimpressed from an engineering standpoint, however, I find it amazing that something as seemingly simple as a record was ever brought to life.
(By "unimpressed" I mean anyone can do it with the right tools/programing and easily build upon the premise. How anyone ever got microscopic grooves to record/create sound is mind-boggling hands-on mechanical engineering )
Your cognitive dissonance on these subjects is mind-boggling. What does "anyone can do it" even mean in this context? If we're comparing the invention of the record to the invention of digital technology.... no, not 'just anyone' can do either of these things and the comparison makes no sense. I'm unimpressed, and being unimpressed makes me feel so smart!
We definitely need more brilliant thinkers like you in this world! Find a good woman, and please have lots of kids!
Originally "Switched-On Bach" was attributed to Walter Carlos who was actually a woman, Wendy Carlos, but record executives believed that no one would buy this album if people thought a woman had created it. Reality was acknowledged in the CD release. That aside, this was a fascinating look at our media and how they actually reproduce light and sound. Thank you. Subscribed.
Old comment I know, but needs a correction. Walter Carlos _was_ actually a man ... but he had a sex-change in 1972 (5 years after recording this album). This was pretty well known at the time, I certainly knew about it in the 80s before the CD-release. It's one of my first LPs and still gets played occasionally.
You might notice the LP-cover of Switched-on-Bach doesn't say Walter or Wendy Carlos, the first line is "Trans-Electronic Music productions" , I don't think that's coincidence. ;)
@@njones420 Thank you for that. As I have both the original LP and the CD, I will check it out. More than that I will see if Wendy ever wrote a autobiography. I think it would be fascinating. She changed how the world heard classical music.
@@curtisrodriguez938 I'm sure there's a lot more to the story. I have no idea what the views were in the 60s/70s, but I did read she was having to wear fake side-burns etc for interviews and appearances. There must be a documentary somewhere...
Sorry if that first comment sounded snarky, it wasn't meant to, but I just read it again :)
@@njones420 No worries on the snark account. It did not come off to me like that. The back of the album cover of "Switched-on Bach," at the top left corner it says, "Electronic Realizations and Performances by Walter Carlos with the assistance of Benjamin Folkman. There was no mistaking that the label was holding out the performer as a man. The CD notes indicated that the label was reluctant to credit a woman because people would not buy it. When I first saw the CD, I thought that either Walter underwent a profound change, a sex change. But after reading the CD notes, I understood them to say that Carlos was always a woman.
The attitudes about women not being commercially viable has been a factor in the entertainment business for decades. One of the Star Trek writers was D.C. Fontana, a woman. Even today I wonder why the Harry Potter books were credited to J.K. Rowllng. I was around in the 1960's and 1970's. Sex changes were rarely written about and were not part of normal cultural interactions. The movie "Myra Breckenridge" was one movie about a transexual. It was a very different world.
@@njones420 You are correct. Wendy Carlos was indeed born a man who transitioned to a woman. The record label did not note the change for marketing reasons. I never saw any interviews with Wendy before or after her transition. Apparently she wore fake sideburns when she met Stanley Kubrick (She did the soundtrack for "The Shining.").
Thank you Mr Edison for so many remarkable inventions, i think you'd be amazed and proud to see your work used and improved on through the years.
Thank you. This was absolutely fascinating, especially since I play a capacitive controlled instrument. :)
+ThomasGrillo Hey Thomas
What is a capacitive controlled instrument? o.O
Theremin. Very cool. Only instrument you play without touching, as far as I know
Ah, so that explains it. Ex-wife thought it was a Theremin...
