Home built mechanical sound recorder

[@holtzman72]

For all who have questions: please look my second video with closeups and explanations, this video is just what I have, no plans in any form exist for this device. I built it from scratch improvizing and using existing parts!kzbin.info/www/bejne/eJ-QnHd5mtGmeK8

[@orospakr]

Hi! This is such an amazing project. I would love to hear a direct capture of the reproduced audio. :)

Is it a way to record music on a blank cd with a record player cause i got a lot of blanks ??

[@martinda7446]

I just adore this. The irony of using a CD for the medium. Magnificent.

[@wii1245]

Martin D A how do you vacuum the swarfs?

[@flamencoprof]

Amazing how the application of intelligence can reduce what was once unattainable technology to something as basic as this. Millions of people have enough education to figure out how to do this, but have not. I am impressed and congratulate you on your ingenuity and practicality.

[@holtzman72]

Thanks for your comment! I actually have used many ready-made components here, so it is not as basic as it seems. The arrangement is simple, but the components are not: computer for equalisation, amplifier, CD drive, gearbox, speaker, decent turntable...

[@flamencoprof]

By "basic" I meant that you have understood the basic principles involved. Using ready-made components is thus a demonstration that you have understood how each component works, and repurposed them in an intelligent way. I actually avoided using the words "simple" or "easy" because this is neither.

[@chapeteglian]

EXCELENT! You should use a laser disc to make an LP!

[@rich3371]

I love it man, this is the kind of stuff that I spend all my free time on - really cool intricate things of no real consequence. Figuring out how to make something is what makes life fun. Good job from a fellow "inventor".

[@ВладимирЮрченко-д6ю]

Хорошо получилось! Звук на уровне электрофонов 2-3 класса, но я думаю, что нет предела совершенству! К тому же нарезано в домашних условиях, это достойно уважения!

[@котматроскин-п9о]

[@1959Berre]

Finally the proof that CD sounds better dan vinyl ;)

[@CoopyKat]

Uh....NO, that's not what this "proves". CD does not sound better, because digital sound cuts out a lot of the analog sound when it's transferred to CD. The reason people THINK CD sounds better is that it's scratch and noise-proof. Vinyl records/analog recording is way better. You are confusing the physical material of the CD with the concept of ANALOG SOUND.

[@SilverShr0ud]

CoopyKat You missed that joke, hard.

[@ksteiger]

CoopyKat horse shit. why do people insist on saying thus bullshit?

[@arifakyuz7673]

Dude, it was a joke. He even put a damn WINK emoticon! I respect your opinion, but wrong comment to talk about this.

[@whatevernamegoeshere3644]

@@CoopyKat Even then, you can put any data on cd. If you want, it's 2 minutes of data in a 700 meg file that has everything from 2Hz to 100kHz at a high sample rate. Then it would be objectively better than vinyl in that it has literally the same audio down to billionth decimal accuracy but it removes the mechanical issues coming from needle springs and dust. And if you want proof that this works, well yeah most modern records are burnt out from a digital copy with a high sample rate

[@holtzman72]

Спасибо, Сергей! Ничего конкретного этот эксперимент не преследовал. Просто интересно было малыми средствами воссоздать ушедшую технологию. Меня как дизайнера вообще интересуют "тупиковые" ветви развития техники. Существовало много интересных аудио и видео форматов и способов записи и воспроизведения. Всё это забывается, а ведь были и гениальные решения, борьба за улучшение характеристик...

[@holtzman72]

Actually, you are right. All the deep bass was digitally removed before recording. It causes greater amplitudes on recording and playback, which add great distortions. Only professional cutting equipment is capable of good frequency response both for bass and for treble.

[@pulezanpulezan4918]

Congratulations on making this great machine. The recorded sound quality is actually pretty good. Would be very cool to own one of these record cutters.

[@pcallas66]

That looks like a belt driven turntable. I'm amazed that it's strong enough to pull the platter with the high pressure drag from the cutting head. This is a great video. The audio is clean on the cut, also. Thank you for sharing. I love innovation!!!

[@lizichell2]

its very good for a home made cutter. The bass is not distorted and its very balanced

[@RobertoGinsburg]

AMAZING!! The principle of Thomas Young and Thomas Edison and E.C. Wente applied to a CD. Youre a genius really.

[@СергейУдовиченко-в9ж]

In the Soviet Union, this method was used to make plates on postcards with a thin coating. The plates had drawings on them. My mother was given one with a voice greeting and three songs

[@holtzman72]

I do not burn CDs any more. All my CD players stopped working while turntables still survive. Many burned and even regular CDs became unplayable while LPs still play back good quality. This project was just fun for me, kind of technological humor.

[@antonnym214]

Well done! The playback quality is way better than i expected.

[@Zarkovision]

That is a highly impressive result. Compared with my Gakken phonograph from Japan which works basically by the same system it is really great.

[@holtzman72]

Thank you for your kind feedback! The speaker is not so large but heavy. It's about 8 cm and weights about 200 gram. I removed the protective cap from its magnets to save weight, because CD tracking drive feels hard moving cutting head, counterweight and the rigid frame. The weight load on the stylus is just below 100g. Funny enough but i don't know what wattage the speaker is rated, I bought it second hand with no specks on it. It's about 5 Ohm and feels to be above 20W, at least.

[@dave631bnetzero]

Hi I see your transducer (Speaker) has a second magnet. This is called a "bucking" magnet and helps to remove unwanted magnetic field from the back of the speaker that will effect a CTR tube. It is reverse phased, meaning it drops the magnetic strength of this transducer. Removing it will make the magnetic strength higher on this cutter. (Louder recording). Nice job!

[@sbanner428]

Impressed by how good it sounds, nice work :D

This is the best use i've seen for a CD. Well done! Sounds good to me. All good wishes.

[@Sirrom0206]

I love this project! I never would have thought of doing this.

[@derpinbird1180]

Thats really stunning quality especially for a homemade device like that

[@williamdrake6711]

that would be cool to have the digital song on one side so you could play it in CD player, but then have the cut song on other side to playback on record player. so you then have a single in both mediums....

I like very much such projects. It looks great, like real McGyver work.

[@holtzman72]

[@tarstarkusz]

The sound quality is rather surprising. Not exactly hi-fi, but doesn't sound 1/2 bad either.

[@holtzman72]

Это устройство собиралось из "мусорных" компонентов, никаких чертежей не было. Если Вас интересует что-то конкретное, то я, конечно, поделюсь информацией. Например, игла-резец заточена на конус с углом около 80 градусов. Работает она под углом 30 градусов к поверхности диска. Давление - 100-150г. И так далее, можете спрашивать, что Вам интересно.

В производство бы такую чудесную вещицу запустить. Для всех любителей делать не только перезаписи, но и записывать голоса близких людей. Бизнесмены, намёк понятен ? Надежда на вас, так как не все с золотыми руками рождены.

[@danielrperez5778]

Amazing! Long live DIY! By the way, it doesn't have to be a blank CD: of course any CD, written or blank CD-R or DVDR will do.

[@the_eminent_Joshua_E_Hrouda]

Even the blank, clear piece of plastic that they sometimes include on a spindle of discs! :)

[@nicolamastrorilli4454]

Di molti visti su FB... sicuramente il migliore.. congratulazioni..

[@BurkenProductions]

Nice! So now you can have both digital and analog data on the same disk! Awesome!! :D

[@holtzman72]

The small aluminum cone is made of foil from disposable baking dish. There is a balancing arm connected to this cone, on the other end of this arm engraving needle is attached.

[@MikeGervasi]

Brother, you get an A+ for inventiveness and effort.

[@holtzman72]

Just to clear things: what you see is an experiment, this particular machine is not for sale. You can not record "real" vinyl by it because it is not reliable enough to make multiple copies, and the groove depth and record level are smaller than normal. And you can not play back on every turntable - the record diameter is smaller than standard. A good turntable is needed, but the needle wear may be greater than normal.

[@LHUPA]

Simply genial! I'm building one with an old HP inkjet printer and portable phonograph turntable with an hard disk drive as cutter head (knowing that an HDD can make a speaker with the coil and arm that can transfer signal from the input to mechanical energy driving a stylus that make a groove on the CD/DVD.)! Actually, I merged the project to another low priced all-plastic HP inkjet printer so called "APOLLO" that's stunningly brought all the solutions to the cutter head motor installation!

[@stelleratorsuprise8185]

Well done! it would be cool if the CD still works in a CD player, this could be a good gimmick for a present.

[@quantumleap359]

Very nice work, excellent sound quality. You are quite the craftsman. Bravo!

[@HelloKittyFanMan.]

Oh sure, with all those hisses, and all those snaps, crackles, and pops! I'm sure that's why PhilSony was so successful with their digital disc invention!

[@captaintrips2980]

Great idea, using a compact disc as a recording medium. But it will wear quickly.

[@marlucan]

The lathe must round slower than the plate spins ¿right?

[@suvamay2011]

Fantastic idea. I like your project.

[@whopoder]

Muito bom! Apenas uma dica: Depois de grava, antes de tocar, limpe a superfície do disco. Evita estragar a agulha do tocador.

[@holtzman72]

Thanks! Yes the idea is to compensate RIAA equalisation of phono preamp. In fact, it is not enough for correct recording and for this reason i put a capacitor in series with the cutter.

[@holtzman72]

I was inspired by works of others, but there was no any guide or plan. In particular, I got much useful information from David Nelson's channel. Actual vinyl is a copy, not a master recording. I did try to record on transparent plastic, but a CD is still better. The size is critical, too. Recording on larger size discs is difficult for a turntable since there is a lot of drag.

[@thecrazy8888]

man the more i lisent the more im impressed this is incredible, I wish you gave some explanations

Hello Maksim, I wouldn't even have thought of using a bank CD on which to make the recording. It would never crossed my mind that it might be possible to do what you have done. You are a mechanical genius. :). Peter Nolan.(Ph.D., experimental physics). Dublin. Ireland.

[@holtzman72]

Costs of production and equipment also played their role. CD is very cheap to produce, and a CD player is a relatively easy-to-produce device. So the profits were very high when first CDs and players were sold, they were expensive. Any tape comparable to CD quality is way more expensive. Pre-recording tapes is also expensive and often the quality was awful.

[@MarkDaGardna]

Not sure if there is a market for this technology but I think this is really cool...

[@Joaomotta01]

Qual é o peso da agulha em cima do CD????

[@holtzman72]

It is about 100g.

[@Joaomotta01]

Muito obrigado meu amigo eu lhe desejo muito sucesso a sua vida, parabéns pelo seu projeto abraço.

[@williamschmidt-hansen6311]

The song is Frank Sinatra - The world we knew. Very nice!

[@holtzman72]

Thank you! The quality is not as on actual vinyls, and not stereo. What you hear captured by camera mic is more or less its frequency range. See my channel for update - it is not a tutorial but hope this helps.

[@JoeSmith-cy9wj]

About time somebody got an infinite sampling rate into one of those

[@MrCougar214]

Cutting the tracks onto the cd media also seems to reduce noise for quieter playback. There are no pops and skips which I am assuming is because the cd media is denser material than vinyl.

[@FG-td4vs]

Pops and clicks only exist when the vinyl is dirty or damaged, nothing to do with the materiel used

[@MrVinylObsessive]

Fascinating stuff! Which material the cutting stylus is made? Is it heated?

Thanks indeed everybody for your reactions, they are much appreciated!

[@holtzman72]

Hi Alessandro, The dimensions are 130mm x 38mm. But this is not important. What is important that the distance between the main axle (VCR head in my case) and the needle tip should be as short as possible. This helps to keep all the structure rigid - it is very important for precise cutting of the grooves which are close to each other. I have this distance 120mm which is bad but with my huge speaker it is what I got.

[@gyrofrank]

I would love to make and share "Vinyl CDs" like these 😍

[@MikeGervasi]

Compensate for the RIAA curve of the phono input (if using one) on the source music while cutting. This however does sound like you are going into a standard amp input with no RIAA preamp curve.

[@dave631bnetzero]

NICE. Maybe a neodymium full range will help. Ceramic is a lot lower output. Size is not important as you are using the motor of the speaker, not the frame or moving mass. That has been removed. STRONG MAG WITH LOW MASS! Set two off by 45 degrees and you have stereo!

[@WAQWBrentwood]

I wish I had a rig like this back when half my attempts at burning CDs generated "coasters" as I would have loved to have been able "recycle" those disks! Instead the became airgun targets!

[@janomusicashow]

What weight did you give to the needle to make the groove on the disc? Did you need to heat the material to be recorded? Thank you! excellent work!!!!!!!

[@foureyedchick]

Not bad for a home-brew DIY record cutter !

[@saschalausen3198]

HAHAHAHA

[@holtzman72]

Thanks! I tried office pins, then switched to drill bits. I sharpened both to form a cone, slightly less than 90 degrees. See my another video for sharpening methods.

[@holtzman72]

Well, small disc diameter IS a problem since there is auto-stop function. And this particular tt model even has a mechanical stopper which does not allow the tonearm to get close to the center, thus my record is less than 4 min. Anyway, the auto-stop feature is disabled in my case - I simply got into the guts of my tt and put some temporary spacer close to the spring loaded part responsible for auto-stop.

Very cool video and great job! I would like to have something like built so I could cut my own records. I have a good Technics turntable, but, I don't have the skill to make the lathe. If there was a way to install a sliding track on the board for the cutter, you could probably cut full length records. :)

How do you transfere the horizontal motion from the speaker to vertical motion in the needle?

[@holtzman72]

The harder, the better. It's difficult to sharpen hard steel correctly, though. I started with office push pin needles, then moved to a broken drill bit. The stylus is not heated at this stage, too complex for me...

[@NBTVer]

Oh yes but it is only necessary to go down that low if you want to keep a reasonable DC component (to alleviate tilt) - but you can remove the bottom 100 Hz and still have quite a good picture - I would be more worried about the higher frequencies and speed variation. By the sounds of things I think you should get something useful out of. Worth a try anyway.
