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!😵💫
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!
This is so great and cinematic, imagine a movie with this scene, than soldiers on the field running in slow motion.
This is the best RUclips 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!
Wow, Just wow!! The view is incredible of the groove and needle moving, thanks for the setup explanation at the end
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
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.
Great explanation! Thanks!
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.👍👍👍
Probably the best vinyl related video there is on youtube... :D
Awesome of you. An actual motion video instead of freezing frames. My hat off to you.
The classical music gave an AvE-like touch to it...
Or Stefan Gotteswinter :)
Love the random ''Hello Trixie'' 🐾🐾😂 2:50
Trixie's hair @ 0:51
Thanks for the slow-mo video! This is something you sure don't see very often...
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
Huma-Huma are ripping off Prokofiev's Romeo and Juliet! ;)
Thanks for the cool stylus shots.
That's amazing!
Thank you for the effort. That was awesome. Since I was little back in the 70's I've wondered what that would look like.
Great video David!
Ey found one of your comments and I’m the first one!
Great comment Kevin!
the genius and effort behind this is amazing!
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.
This is incredible, thank you!
very cool to see this so close up
The superior format. Such perfection and reproducibility plus infinite bandwidth coz analog.
Thanks. :) You've made a great deal of service for all the DJ's who knew already how it all works but had this need to see it zoomed and in slow motion. :) Cheers!
What a great job you did ! I enjoyed this, thank you for posting this video.
This is worlds better than the other video. I’m sharing this with the dj pages
love these videos on problem solving and cool camera setups
Mind blown goodstyle!😵💫
I would bet you a king's ransom that this man married an original Mac. Only 4chan attended.
what an absolutely excellent video...hats off to you sir!
Great demonstration of why we have nasal hairs.
Fantastic!
this is really interesting !
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.
This is so amazing and cool to see it up close
Unbelievably cool! The b&w Chronos is great for that shot.
Man, it's just awesome! Thanks for the video!
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.
ABSOLUTELY PHENOMENAL
That angry grandpa theme
oh yeah, this was VERY interesting
THANK YOU
This is amazing! Thank you! Plus, i love that song.
Thanks very much for doing this. It's excellent.
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.
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.
AMAZING.............
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!
Excellent demo.
This is amazing and beautiful-ty
watching that stylus skipping grooves hurt me
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.
That was awesome! Thanks for sharing.
Fantastic.
Do a cg version of the needle in a 10 ft tall groove, to show the textures that produce bass vs treble etc
Look at this Phonograph. Everytime I do it makes me laugh...
Good vid
That is very very cool, thanks for taking all the time to set this up. I thought the record player grooves were vertical, not horizontal. Now I know...
You're not completely wrong - the needle moves up, down, left and right in a 45 degree "V" so it can play stereo by using the two axes.
A needle that can only move left or right can only do mono (unless digitally encoded with stereo data!)
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
Boop!
Great stuff! Will you try to create your own Dr. Royal Rife microscope?
Very interesting thanks...
María Elena: Los Indios Tabajaras. As printed in the record label
Wonderful job. Well done.👏👍
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.
Wow great video...
4:15 is the sound of the start of many prerecorded music albums on compact cassette tapes...
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
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.
what are those crystals on phonoraph head? looks like frost.
I'm guessing it's some sort of corrosion.
Great work and would like to see more.
cool stuff 🔎🎶
i am still wondering what camera is that... looks pretty cool
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?
Que maravilha o funciomento do disco de vinil.
Awesome
HOW DIRTY CAN YOUR STYLUS BE?
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.
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...
Gracias por compartir
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?
that was awesome dude. thanks.
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.
Look into cine foil, it's a matte black foil that doesn't reflect light as much as what you're using. Check out the Matthews infinity arm if you want camera support similar to the machinists arm you used but with interchangeable tips.
3:29 cat near exposed power supply haha
Ahhh, Yes... That would be Schrödinger's Cat!
Interesting, thanks for sharing.
Magic
Looks better than that 3 second footage via electron microscope that went viral...
not interesting ? .... fascinating !!! why was the stylus jumping track ?
are those the actual sound waves imprinted on the record? :o
Yes
Can you do this with a record covered with water? Maybe also compare the outer and inner groves. Easily the best close up shot I've seen.
really cool...interesting...respect well done..
I expect a denser accent with that music at 0:15
Renewable Oilcan Rim Is that a Stefan Gotteswinter reference?
You could have tried coupling the light in with a beam splitter in the the tube to the camera. So you may focus it more effective where it is required, possibly reducing the required power, solving the heating and some stray reflection issues.
Ah, someone already suggested that...
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 🙂.
Seeing it at this scale, it's amazing how well the whole contraption works to drive human reproduction.
Any more subjects planned for this rig?
Bro, this was awesome.
just an Idea for your lamp btw, . you need to get a cheap aliexpr "Universal tablet ipad holder". Its basically a desk-clamp with a bendable arm and on its end you have a swivel joint (remove ipad fixture) (insert diy lamp fixture).. Boom! micro spotlight on a bendable arm with clamp! nailed it
Lol cat is tryna die standing almost on the power supply
