Home built mechanical sound recorder

- Here is my version of a mechanical sound recorder based on a turntable. It's possible to record up to 4 minutes on a blank CD. The quality of my camera's mic captured sound is lower than that of the real playback, videos with original sound will follow.
By now, the system records sound files played on computer, in real time. The files are "anti-RIAA" equalized. For further bass attenuation, 2u2 bipolar capacitor is connected in series with the cutting head. I hope to build some analog anti-riaa filter and to use it as regular voice or music recorder.
The cutting head includes a powerful all-range speaker. The speaker drives the lightweight aluminum arm to which the "indenting" stylus is attached.
The mechanism which moves the cutting head is just a CD player's tracking device:) - วิทยาศาสตร์และเทคโนโลยี
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!th-cam.com/video/Bn-kDCelsBM/w-d-xo.html
Hi! This is such an amazing project. I would love to hear a direct capture of the reproduced audio. :)
что использовали в качестве резца?

Спасибо.
Is it a way to record music on a blank cd with a record player cause i got a lot of blanks ??
I just adore this. The irony of using a CD for the medium. Magnificent.
Martin D A how do you vacuum the swarfs?
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.
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...
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.
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".
EXCELENT! You should use a laser disc to make an LP!
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!
ндэээ звук нисавсем качиственный !!!сильно теряет качество из вонтаво длинного штока и видать иза иглы и зависит от температуры нарезаемого пластика!!!
Finally the proof that CD sounds better dan vinyl ;)
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.
CoopyKat You missed that joke, hard.
CoopyKat horse shit. why do people insist on saying thus bullshit?
Dude, it was a joke. He even put a damn WINK emoticon! I respect your opinion, but wrong comment to talk about this.
@@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
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.
I love this project! I never would have thought of doing this.
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!!!
its very good for a home made cutter. The bass is not distorted and its very balanced
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...
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.
AMAZING!! The principle of Thomas Young and Thomas Edison and E.C. Wente applied to a CD. Youre a genius really.
That is freaking awsome! Great idea using CD's
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
Love this guys projects. One very clever and resourceful person. Cheers.
Thats really stunning quality especially for a homemade device like that
This is the best use i've seen for a CD. Well done! Sounds good to me. All good wishes.
Impressed by how good it sounds, nice work :D
Esta maneira de gravação analógica é fantástica. Parabéns! Rio de Janeiro RJ Brasil
Very nice work, excellent sound quality. You are quite the craftsman. Bravo!
Fantastic idea. I like your project.
This is great! I really enjoy experiments like this!
மிகவும் அருமை.
வெகு நாட்களாக தேடிய செய்தி.
நன்றி .
வாழ்த்துக்கள்...
Well done! The playback quality is way better than i expected.
For something home made and that really looks like it as well the results are impressive, I like it..
I like very much such projects. It looks great, like real McGyver work.
Thank you! And believe me or not, I did not hear about McGyver until your comment, there is really cool stuff in it.
The sound quality is rather surprising. Not exactly hi-fi, but doesn't sound 1/2 bad either.
Great results!! Many congratulations.
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.
This actually sounds really good
man the more i lisent the more im impressed this is incredible, I wish you gave some explanations
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.
Brother, you get an A+ for inventiveness and effort.
That is a highly impressive result. Compared with my Gakken phonograph from Japan which works basically by the same system it is really great.
Super cool. Thanks for posting it!
There's something oddly satisfying about putting an analog recording on a CD.
Nice! So now you can have both digital and analog data on the same disk! Awesome!! :D
this is absolutely awesome stuff. Well done.
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.
Nice and simple design! :)
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....

Sir you did an excellent job.
Very good!!!
Sensacional!!!
Ensine como montar essa mesa gravadora. Muito interessante!!!
Parabéns!!!
Thank you, good notice! As soon as time allows, I'll come back to this project and check it.
Maksim.. Fabulous job done
Revenge of the vinyl :)
Absolutely brilliant, BRAVO !!!
So good! Low frequencies are great! And I listened to this song today haha. Great job!
Make a tutorial on how to build one!
Di molti visti su FB... sicuramente il migliore.. congratulazioni..
clearly demonstrated.....very good effort...
Hi, what did you put in front of the speaker? Can you explain me how did you do that cone silver, and what to did you put? (Sorry for the english, i'm italian) please answer me. =)
Amazing accomplishment!
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.
Thanks indeed everybody for your reactions, they are much appreciated!
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.
Even the blank, clear piece of plastic that they sometimes include on a spindle of discs! :)
Sounds good on playback, the frequency response is quite nice, if not for YT's compression and mike quality. Nice project.
Качественно нарезало однако! Супер!
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!
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.
Awesome, pretty good work. Thank you
Great job! I wish I had you build one for me.
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!
Great idea, using a compact disc as a recording medium. But it will wear quickly.
Amazing work.
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.
Great! Simple and efficient!!!
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.
Pops and clicks only exist when the vinyl is dirty or damaged, nothing to do with the materiel used
Totally brilliant - well done. What to do on a wet afternoon - lol
amazing, I need to build this machine too!!! congratulation!!!
How do you transfere the horizontal motion from the speaker to vertical motion in the needle?
my speaker that I use for recording head is 10.5 cm wide.How far will have to be the head of the VCR from the needle engraver?
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!!!!!!!
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. :)
As the distance between the needle tip and the main axis (head VCR), can fit 55 mm?
awesome! you've invented the 45 :D
Hello Maksim,
Well done. Your device is very impressive. Peter Nolan.(Ph.D., experimental physics). Dublin. Ireland.
About time somebody got an infinite sampling rate into one of those
Nice setup!
Not sure if there is a market for this technology but I think this is really cool...
Since he used the motor that move was a doll to make move his head recorder, an alternative could fit one of those GEAR MOTOR for this purpose?
Fascinating stuff!
Which material the cutting stylus is made? Is it heated?
Genius Inventor!
That’s really impressive
Well done!
it would be cool if the CD still works in a CD player, this could be a good gimmick for a present.
Excellent Work my friend. Love to see something like this and I also mod hi-fi. Look forward to your videos :)
Would you custom make music if you had a customer who requested it? some already made music that was found on the internet and asked you to put it on cd, vinyl-style. like you did in this video?
Not bad for a home-brew DIY record cutter !
its the best one ive seen and the sound is excelent, wonder if it would be possible to polish old vinyl back to blank and record new track on it
Everyone need to see this!
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.
It sounds pretty good!!!
And it sounds great!
Wow I would buy one of these.
Thanks for your feedback!
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!
Omg that is amazing!!
I have watched the second video but still did not understand what is driving the recording arm so steady
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.
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!
