TAOFLEDERMAUS Damn jeff i see you on every video i like

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!

Wow, Just wow!! The view is incredible of the groove and needle moving, thanks for the setup explanation at the end

This is the best KZread 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!

This is so great and cinematic, imagine a movie with this scene, than soldiers on the field running in slow motion.

How about lighting through the lens with a beamsplitter like a metallurgical microscope?

@altaroffire56

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

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?

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

the genius and effort behind this is amazing!

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.

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.👍👍👍

Great explanation! Thanks!

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!

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.

Probably the best vinyl related video there is on youtube... :D

what an absolutely excellent video...hats off to you sir!

Awesome of you. An actual motion video instead of freezing frames. My hat off to you.

How much different would it look by simply running the record slow and locking the arm?

Excellent demo.

This is worlds better than the other video. I’m sharing this with the dj pages

The superior format. Such perfection and reproducibility plus infinite bandwidth coz analog.

Great work and would like to see more.

this is really interesting !

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.

that was awesome dude. thanks.

That angry grandpa theme

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.

Huma-Huma are ripping off Prokofiev's Romeo and Juliet! ;) Thanks for the cool stylus shots.

Fantastic.

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.

Interesting, thanks for sharing.

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!

Look at this Phonograph. Everytime I do it makes me laugh... Good vid

AMAZING.............

Wow great video...

oh yeah, this was VERY interesting THANK YOU

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.

Very interesting thanks...

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.

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!)

really cool...interesting...respect well done..

I would bet you a king's ransom that this man married an original Mac. Only 4chan attended.

Gracias por compartir

nicely done

Great job

Do a cg version of the needle in a 10 ft tall groove, to show the textures that produce bass vs treble etc

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.

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.

cool stuff 🔎🎶

Also please link the music track you used at the start of the video... It is lovely.

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.

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.

Boop! Great stuff! Will you try to create your own Dr. Royal Rife microscope?

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.

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.

can you do a highspeed video of an electric lighter with dual arc?

4:15 is the sound of the start of many prerecorded music albums on compact cassette tapes...

Any chance you can do another video in real time shot @ 60 hz?

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.

Nice video

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?

Whats that led light ? Try somethink like emissar d4

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?

I always thought the needle went up and down to detect the signal, it appears it moves side to side instead.

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.
