Thanks for explaining how you did it. Definitely more complex than I imagined.
TAOFLEDERMAUS Damn jeff i see you on every video i like
It's how the sound gets put on the vinyl in the first place that burns my head out!😵💫
Who needs an electron microscope...
Yes please!
who doesnt?
That's only 500 microns minimum dimensions you can see with a microscope is 3 orders of magnitude below the video dimensions shown here!
Man, the amount of effort you put in to this is is impressive on so many levels, you deserve more than the mere like I can give you, thank you, so much.
Electron microscopes kill / modify the sample being viewed and should not be used in medical settings. It is possible to create a live culture microscope which can observe even a virus in its living state. Invented originally by Royal Raymond Rife. Even Universities do not have the equipment which I am familiar with. Its actually quite pathetic especially in 2023. Not worth a $190,000 tuition in the slightest. Get better equipment that can study LIFE and smash those electron microscopes. They shouldn’t even be allowed to exist because it makes too many experiments invalid.
Minds = Blown
Arg! You beat me to it! The last time I tried this I melted my record and the microscope lens got way too hot. Fantastic footage, I'm glad you got it to work!
How about lighting through the lens with a beamsplitter like a metallurgical microscope?
A beam splitter would halve the light intensity going to the sensor, since the other half would get reflected back to the light source. Also, I don't think lightning through the lens is ideal unless you're filming a surface perpendicular to the beam.
Will need to give that a try. Will lose some light due to the beamsplitter but the lighting should be much more efficient
Is the internal oscilloscope working yet? Because if it is, this would be a really cool demo of it.
Hello
Mike, you pulled out of the DNA machine this filter which blocks only the laser light wave length,
would this not be suited for illumination of the stylus through a beam splitter and filtering out the laser light?
Would love to see a video like this with the real time audio produced by the record included
I agree. It would be more interesting to see the actual track synchronized w the music. Having been brought up w Hi Fi it’s amazing that they ever came up w this. I’d love to see how quadrophonics system worked. I liked the part where the needle skipped the groove a few times.
True quadrophonics was 8 track tape. LP's were encoded/ decoded 2 channel sound. Thru a processor.
I have to be honest: As a hobbyist photographer the actual footage you got was much less interesting than you explaining the building of the actual setup to film the action. :P
Wow, Just wow!! The view is incredible of the groove and needle moving, thanks for the setup explanation at the end
Great explanation! Thanks!
How much different would it look by simply running the record slow and locking the arm?
There will probably be some subtle differences, especially to do with dust physics, and the scratches would be completely different.
Could you set the high speed camera to a slow frame rate?
:D
Yes, it can be set down to 0.025 fps XD
That angry grandpa theme
The classical music gave an AvE-like touch to it...
Or Stefan Gotteswinter :)
This is so great and cinematic, imagine a movie with this scene, than soldiers on the field running in slow motion.
HOW DIRTY CAN YOUR STYLUS BE?
Great video David!
Ey found one of your comments and I’m the first one!
Great comment Kevin!
This is the best UA-cam video of a magnified LP record playing. Interesting to see how the stylus starts clean and then gets lost with dust and particles. Also, the grooves are all over the place. Thanks!
I expect a denser accent with that music at 0:15
Renewable Oilcan Rim Is that a Stefan Gotteswinter reference?
from like 1:36 on, can anyone explain the stylus jumping lanes?
Cool stuff! Your records are really dusty though, and the stylus is collecting lots of rubbish all along. Maybe clean them first? Also you might want to adjust the weight and the anti skating, as the needle is jumping quite a bit on the grooves...
not interesting ? .... fascinating !!! why was the stylus jumping track ?
Huma-Huma are ripping off Prokofiev's Romeo and Juliet! ;)
Thanks for the cool stylus shots.
Have you tried burning magnesium (ribbon for example) as a source of illumination? Yes, it is short term, but often times short term is all it takes for high speed filming.
Somewhat of a back to the roots of photography aproach? Sounds fun, keep an extinguisher at hand.
Holy crap! This was extremely interesting! Thanks for all your hard work!
And that small light is just insane! Where can you get them?
Thanks, I will subscribe! Keep up the good work!
I guess Im an old fart that I think this is amazing. Being nostalgic in this day is a real curse. They can't destroy the past fast enough.
You can see how much material its wearing away everytime you skip the needle. And even just following a concentric groove, its dragging and taking some vinyl with it occasionally. Easy to see how a record wears out.
It may be the heat from the lamp softening the vinyl, and causing excess wear.
Probably the best vinyl related video there is on youtube... :D
That's amazing!
watching that stylus skipping grooves hurt me
Ah, not a proper Tesla500 video with a guest appearance of Mr.Cat.
Also please link the music track you used at the start of the video... It is lovely.
😂 the cat can destroy everything in one second.
That's DJ scratch
To those saying run the record more slowly... wouldn’t that make the needle not move as much in the cartridge due to the tone arm having less inertia?
compu85 I think so too. I don't think you'd see the same level of wear on the vinyl either.
Love the random ''Hello Trixie'' 🐾🐾😂 2:50
Trixie's hair @ 0:51
are those the actual sound waves imprinted on the record? :o
Yes
Sure was a lot of effort but a great result!
However, if you physically ran the record at 1/100th speed, then you could have managed with 1/100th of the light and/or run the camera slower. (The needle follows the grooves just the same at 0.33 rpm!)
Andy Lee Robinson not all of the physics involved with this is linear, I'd imagine, therefore the needle would behave differently on slow speeds
No, the groove *dictates* the motion of the needle so that is linear. The signal generated in the pickup coil relies on relative movement of the needle and the arm and may not be linear at all speeds. The arm has much greater inertia and integrates (follows) the average position of the needle.
If the speed was very very slow, the whole arm would move with the needle and either no signal or a distorted one would be generated as the arm becomes coupled.
At very high speed the needle may jump out of the groove on high frequency or high amplitude sounds as the rate of change of path exceeds the needle's ability to remain in the groove - just like taking a corner too fast.
Where it would fail is surface damage, though.
oh yeah, this was VERY interesting
THANK YOU
Please tell me this music ( song ) name i want to listen in Spotify
Please sir
ua-cam.com/video/2z5rMNH_yTI/v-deo.html
this is really interesting !
Thanks for the slow-mo video! This is something you sure don't see very often...
This is incredible, thank you!
The Dust! Mwahahahaa!! 😈 (Spins in chair)
Do a cg version of the needle in a 10 ft tall groove, to show the textures that produce bass vs treble etc
3:29 cat near exposed power supply haha
Ahhh, Yes... That would be Schrödinger's Cat!
Can someone tell me what music piece was that……
ua-cam.com/video/2z5rMNH_yTI/v-deo.html
Crazy too see how much the needle is moving. I always thought the motion of the stylus would be much smaller. Don't get me wrong, but the microscope effect isn't that huge as the diamond is still pretty small on the picture. but compared to its size, the influence of the groove it huge.
What's also good to spot: these crappy plastic grooves should sound better than a lossless digital recording 🙂? I'm really a vinyl lover, but know about its limitations. Keep in mind, some people pay thousands of dollars for a silver cable, to think it makes the vinyl sound even better. Well, yes, no, definitely no 🙂.
What is the name of the song that is playing?
ua-cam.com/video/2z5rMNH_yTI/v-deo.html
i still dont frucking understand why just a line and one spine can make these frequencies to make these weird vibrations in the air
like bEuh HoW Hax????
All that scientific focus to video a needle repeatedly skipping. Might want to give your tonearm/cartridge setup a wee bit more attention. Just sayin. ;)
Lol cat is tryna die standing almost on the power supply
Great job!
For your lighting issue you would benefit from using an inline illumination setup. As you mentioned the NA of microscope objectives is small, so that cone angle of the reflected light that makes it through the rear pupil of the objective lens is small also. If you could I'd recommend you use an infinity corrected objective lens instead (a long working distance version), and use a beamsplitter & tube lens arrangement. Even with your existing finite tube length objective, at 4x magnification you might get away with mounting some LEDs around the edge of the objective lens for improved illumination.
Also it would be cool to compare a 12" 45 with one of those ultra slow voice- only recordings for the blind (to show the steeper and more shallow angles of groove movement. This really goes to show the wear and tear the record and stylus go through.
Boop!
Great stuff! Will you try to create your own Dr. Royal Rife microscope?
I found your record: www.discogs.com/Los-Indios-Tabajaras-Maria-Elena-/release/6476369
1:09 What are those white chips that get thrown off the stylus or the record? Are they little flakes of vinyl being cut off the record as the needle skips?
Fantastic!
i am still wondering what camera is that... looks pretty cool
What was that discount Prokofiev lmao
Mind blown goodstyle!😵💫
Great demonstration of why we have nasal hairs.
Showing how te needle damages the record every play
with this image and some image processor you can read the disc music :D
María Elena: Los Indios Tabajaras. As printed in the record label
Still looks like witchcraft to me on how music comes out of that.
many tardigrades has been hurt in making this video.
what piece is playing at around 1:25 or so?
those skips are painful to watch.
Que maravilha o funciomento do disco de vinil.
Why do lasers scintillate?
Green Silver I think it is because lasers have very narrow bandwidth which simply means they contain a single wavelength. As the surface is usually not perfectly smooth on microscopic level, therefore the reflected laser beam is not reflected in a uniform way. This causes some patches to interfere constructively and some destructively, causing dark and bright speckles to appear. This happens with ordinary light beams as well but because they contain large number of closely spaced wavelengths. This results in speckles for each wavelength to form at different places. The result is an averaging effect which washes out the speckles
Everything in the nature is a pattern 😏
Looks better than that 3 second footage via electron microscope that went viral...
Hello. Do you have f6645m301gp schematic?
In a perfect world the music would have been "Groovy Situation" by Gene Chandler. Or, "Hot Stuff" by Donna Summer, because the illumation is so hot.
very cool to see this so close up
The superior format. Such perfection and reproducibility plus infinite bandwidth coz analog.
Listening to this with headphones scared the crap out of me! I thought MY 3d printer had somehow turned on and was rouge printing lol. Cool video other wise.
THE ANGRY GRANDPA THEME SONG!!!!!!!
Tesla500 himself only has the prototype version of his camera ... Ironic
Try some white vinyl?
Wow! Don’t know if anyone else has asked this, but is it a myth that shouldn’t play an LP more than once a day due to heat distortion? Asking for a friend🤔
Yes it's true, you shouldn't repeatedly play a record surface more than once a day because the vinyl surface needs to rest because it heats up due to the friction and the repeated playing will wear out the grooves.
I would bet you a king's ransom that this man married an original Mac. Only 4chan attended.
Awesome of you. An actual motion video instead of freezing frames. My hat off to you.
Hugely complex setup and required lot of efforts for typical setting up those gadgets. We are lucky to have such a video - thanks to you.👍👍👍
what are those crystals on phonoraph head? looks like frost.
I'm guessing it's some sort of corrosion.
Plz for your next cam includ a fine tuning stand and lens for a microscope objective. I desperately need this for some of my electrical, crystal, and magnetic slides.
Very interesting thanks...
I looked it up, cuz I couldn't remember which way is the needle move. Imagine a little x on the front of the needle standing up right. The right channel is the left wall and it signal causes the needle to move diagonally up into the right, and then the right side of the groove causes the needle to move diagonally up into the left .
I believe the two movements are at 90° angles to each other .
But the two movements combine on those 45's to create the stereo signal .
I had thought it was plus shaped when I made my previous comment, but that was 45° out of phase with the truth so this is a correction for that.
Nice ! Also dogging the improved case design & color
Grooves was very suspicious
What a great job you did ! I enjoyed this, thank you for posting this video.
it is intriguing to see how difficult it is to photograph things at the microscopic level. I had never known that so much light was needed. Nice video. I also love the music played. What is it called and who wrote it?
Real late comment:Just agree with all other: Great work and vid! I liked the very last part in which you see how much the actual record is wobbling and how hard the needle suspension must work in sub-sonic region. This might be an explanation to why skating can in worst case get grip on needle/cartride and skip it (inwards). And long before that we have audible distortions.
AMAZING.............
the cat gives me anxiety like he could mess up everything on the table in any second
This is worlds better than the other video. I’m sharing this with the dj pages
That is some very nice footage.
Would it be beneficial to use an infrared filter with that lamp? It should help a bit with the heating; xenon has some big spikes in the 800-1000nm range.
Thanks very much for doing this. It's excellent.
well done if I do say
I swear to god I thought this video was from his channel until you mentioned it.
Wow great video...
4:15 is the sound of the start of many prerecorded music albums on compact cassette tapes...
Nice video
