The First STEREO CUTTER HEAD S001 BLUETOOTH

[zdenek]

The world's first prototype BLUETOOTH cutting head SCB001with its own power supply and power amplifiers and RIAA and FB feedback preamplifiers! The head does not require power cables, i.e. it is completely wireless! I haven't tested it yet, but it sounds fantastic to the ear!

Amplifier power 2x100Watt [impulse in milliseconds]
Battery life at 0dB energy [max +5dB] recording working time 90 minutes plus knife heating!
According to the transducers, the head easily transfers the 20Hz to 20kHz band. Width [front] 74mm, total depth 62mm, height 64mm, mounting pin diameter 18mm [standard]
No improvisation, I will soon share the results with you trolls!
[maybe it will have to be patented, who knows]. this is not a joke, it really works! :DI'll upload a video in a momenthttps://www.youtube.com/watch?v=J2E2oEGgbso

I suspect that the chip extraction system is also built into the head. The chip is wound onto a spool using a nanomotor, which can be removed via WLAN after the cut. Ha Ha...

[zdenek]

yes, in the picture we can see on the left a single burnt transistor BUX22 from military resources from the seventies, on the right side a Chinese chip [green board] transmitter receiver and many other things like a speech synthesizer, memory containing several hundred thousand transistors, I'm not even showing the 32Gb memory in a chip with an area of ​​2mm x 2mm, which contains several dozen billion transistors, I'm getting at the fact that SPEED and ACCELERATION are inversely proportional to mass according to the theory of velocity and therefore power, energy are directly proportional to speed. The transducers must be as light as photons, theoretically speaking of course. I don't know what modern electronics are heading to, but this is getting crazy ... I have a tube amplifier from the sixties, it has 2-3 watts of power, mono, weighs a few kilograms and is hot even when not working but on standby, I also have a modern digital amplifier with a power of 2x200W stereo, it is cold even when working and weighs twenty grams. It is the same with transducers for heads and with everything, such are our times...

The chip does not have to be vacuum-dried with a vacuum pump [they make additional noise], in the first machines it was wound on a pin of the platter and the recordings were fantastic and are still on shellac records today. :)https://www.youtube.com/watch?v=n3oCMl1Oksg

First recording SCB cutting head [pressing] Bluetooth not requiring cables, first recording directly from a smartphone, I slightly overdriven the signal to the camera because I do not have a preview of the level at which I should enter the signal to the camera. The best was Carlos Santana from the 6th minute, amazing. Recording without improvisation, true and real. https://www.youtube.com/watch?v=LHwIhgFPUowisn't that crazy?
low-end is the bluetooth transmitter itself [for $2] a bit of a pain in the ass for feedback, but for experiments it's absolutely great!

[zdenek]

Of course, you can skip the Bluetooth transmitter and input a high-quality stereo signal to the USB input of the cutting head, but that's not the point, the whole trick is to skip the power cables, yes or no?
I am so happy that I scratch my head with happiness that I managed to achieve this!

You were so preoccupied with whether or not you could, you didn't stop to think if you should.

You should build the cutter into a record runner! Voila - truly portably cutter

[zdenek]

drdub ,yes, the difference is ...
As I said, this is a small experimental version, it can be done professionally, but the price will not be $100 per piece of this experimental one, but $20,000 per piece of a professional one,,,

[zdenek]

Here is one of the smallest and most powerful Bluetooth, Mp3, AUX IN, memory card cutting heads and with remote control including feedback. The amplifiers in the impulse have a power of 120Watt x2, STEREO, standard knife input, you can connect knife heating to special spring contacts. The transducers used are TRANSDUCTORS of a Swiss company producing hearing aids for the deaf with an efficiency of 110dB. The head has its own power supply and is enough to record blues, classical music for 65 minutes of continuous operation, the battery charging is wireless inductive, charging takes about 1 hour [special charger]. The batteries are replaceable with a latch. The frequency response according to the transducers from 35Hz to 35kHz. We have not yet publicly demonstrated the head. Recording soon.

SCB45Z

This is the fastest, dynamic, wireless Bluetooth, Mp3, FB, head that we managed to make while maintaining nominal power. It is called the prototype SCB45. The price is not astronomical considering the fact that one transducer costs $ 180 and there are of course two because stereo, I am leaving aside acceleration accelerators and the price of one is $ 75, and there are two, the entire device of microchips and preamplifiers and a powerful smd impulse power amplifier and the whole job is a week.

[zdenek]

Here is the SCB45 Bluetooth and mp3 head with AUX line output, wireless with its own power supply and current and thermal protections and power amplifiers and preamplifiers and remote control amplifiers for $ 2,500 and we get the quality of engraved grooves as you can hear in the film.https://www.youtube.com/watch?v=iJRlNfGhRPY

So for $ 20,000 the head will press slightly better and it will need several dozen kilogram amplifiers and various modules and the quality of recordings will be similar to that for $ 2,500 type SCB45.
The money obtained for the first piece is $ 2,500 will power this troll page [personally I think it is worth waiting a bit]

[zdenek]

If someone had told me two years ago that in the future there would be heads like this SCB45 for pressing and engraving vinyl records, I would have said that this was a planned fraud and that it was impossible to achieve. Over the past two years, I have learned from various people from different environments that such things are possible with current technology and we have done it. This is not improvisation, but a real pressed record. In the future, there will be even better and smaller portable analog recorders with enormous possibilities. I suspect that in 3 years we will make a portable 12-inch recorder that fits in a jacket pocket, which will record records with the quality of factory vinyl records.

[farmersplow]

I suspect the biggest achievement here is the invention of a rechargeable battery that can power a record-quality cutting head for 65 minutes, while also heating the needle and being small enough to fit inside the cutting head (and then still be recharged in an hour). The automotive and mobile phone industries would pay a lot for that. But what do I know, in three years' time I'll know better.

Scientists are tearing their hair out because of the bumblebee. From a scientific, physical point of view, the bumblebee should not be able to lift off for the reason that from an aerodynamic phenomenon, the bumblebee has wings that are too small in relation to its body mass, so it should not overcome gravity, and yet the bumblebee can fly, why did the bumblebee break the law of gravity?

In the case of the head, it is easy to calculate it according to the formula P = IxU = VA, read approximately Watt x electrical efficiency, which we have done, the matter is obvious and we have not broken the physical principle, quite the opposite!
It is the effectiveness, efficiency of the transducers that makes the head of very small dimensions work perfectly, can't you see it in the film? The recording lasts 10 minutes and the batteries have not lost capacity even by 5% of the voltage, not even by 0.1V, after all, I am showing the film without improvisation.

Once again I repeat that it is the high energy efficiency of the entire system that makes it physically and practically possible.
And I will add that on Chinese speakers for $20 you won't get very far, maybe 5 kHz and a sharp drop to the ground... I doubt if their efficiency is greater than 1%, certainly below a steam locomotive...

Hello.
Stereo head test [test of Swiss electrodynamic transducers 120dB]. At the moment the head is powered by power amplifiers and German programmable equalizers along with bass playback, soon it will be adapted as wireless in 2.4GHz connection the latest Bluetooth with super CD audio carrier. We will listen, we will see how it turns out. I record on DVD discs intentionally to obtain confirmation of the highest quality of recording on lacquered mother discs.
The approximate price for a complete head is estimated at $ 5,000 to $ 7,000 per piece. It is possible to listen to the recordings in person at our studio after prior arrangement of the date. The order fulfillment date [without the first advance payment, means that you order a ready-made device, i.e. a head, and pay upon personal collection and test it at the seller's on his media or yours, but you only pay for the $350 knife, which is lossy, and you take it with you.
What does this mean?
This means that you are not buying a pig in a poke, but a finished product that you test on our machine in our laboratory and decide whether to buy a fully functional device that meets your requirements or not. https://www.youtube.com/watch?v=x9_tzcCE4kc

I have come across a huge objection in email: why so expensive?! After all, tweeters cost $10-50 and you can make a great cutting head out of them!

Of course, it will not be a professional cutting head, but a pair of speakers set at a forty-five degree angle, which set pretends to be a cutting head and of course it will also record and cut the groove.

But, unfortunately, something that pretends to be a cutting head cannot serve as professional equipment because it does not provide the refined parameters required in recording professional vinyl records.
And so, if you make something like this [a tweeter head], you achieve a band no greater than 7 kHz, barely audible frequencies and something like this is easy to construct for a price no greater than the cost of tweeters plus a few different materials [plastic, metal, steel]. It will cost an averagely skilled craftsman, for example, 1 hour of work [$10-15] plus materials, 2 speakers and a few additional elements, the total cost will be $50-100.

We came to the conclusion that each additional kHz is no longer an additional $50 but $500.

Why?
The degree of difficulty of making it, i.e. the accuracy and materials used. So: so that it is 9 kHz =1000$
11kHz=2000$
13kHz-3000$
15kHz=4000$
17kHz=5000$ [limit max ]
If someone charges $2,000 for repairing a professional head, it's not because it's easy to repair, but because it's very difficult and a potential service must take into account that while repairing one part, they may damage another functional part and must have a supply of various head elements and its parts.

I have a question for a potential head buyer: "why so expensive?", did you wind the coupling coils in antiphase with 10 micron insulated wire? Do you think it's easy work? If it were easy, every intermediate troll would do it themselves.

That's why the price is like that.

If you want it, I'll give you the tweeter head for FREE because we've already done it and tested it, we've made dozens of different prototypes with different tweeters, but I warn you that the upper frequency range of these pseudo heads does not reach 8 kHz.

[without improvisation, without a digital track under the film image],
Here is the real, true quality of analog recording of a disc with a $3000=13kHz head with feedback on a DVD, [115dB Swiss transducers], of course the bandwidth is much wider with a 12-inch disc [and by the way the gramophone needle and its radius on a 4-inch disc is not able to reproduce frequencies above 10kHz].
The recording is at a higher level than my many 12-inch vinyl records made in the so-called dmm technology from the 80s... and others, at least this four-inch DVD disc does not crackle like crazy... and the bandwidth is even smaller than those 12-inch professional ones...

You were so preoccupied with whether or not you could, you didn't stop to think if you should.

I'm with drdub on this one. There is no reason to have a wireless head on a machine.

I'm reminded of a talk I attended by Tim Vear when he was Vice President of Engineering at Shure Inc and head of the wireless microphone design team. The topic of the talk was "Wireless Microphones" and there were about 100 sound engineers in the audience. He started with, "Hey guys, you want a microphone that works? Get one with a cable on it." This was around the time of the crack epidemic in the USA and we all thought he was on crack or something. He continued, "Whats that? You cant use a cable? I guess we better look at wireless microphones then" I took that to mean that if you want reliability you put a cable on it. There is no reason you cant a run a cable or two to a cutting head that is fixed to a machine.

Let me know if I'm missing something.

Hard to imagine a more fitting way to celebrate 20 years. Genius-level nonsense at its finest.
And yet, we’ve seen plenty over the years (and we’re bound to see plenty more in the future, for sure even increasingly so).

But this one? This takes the cake.
