  1. I have tried this Bimorph component. But the microphones of the 70's machines used very sensitive glass. You can also try an electric piezo disc. the problem is with the disc is that there is no room for it in the vibrograph microphone unit
  2. Hello, I hope this information is useful to you. Saludos. Y Quédese en casa. Stay Home!
  3. I will give you my explanation as a perfect layman. First the nature of the clock sound. If we want to see it like this, the waveform or spectrogram of the clock sound is very simple. It is well within the frequency limits of the human audible spectrum. In fact most of us can hear the ticking of the clock quite well as we approach one in a quiet room. The important thing about this is that the tic-tac is made up of 3 important sounds and very different in terms of time and intensity. The program, using a complex algorithm, makes it possible to locate these 3 sounds perfectly, thus obtaining the spectrogram to analyze the performance of the clock. About the algorithm, my knowledge limits what I can inform you. But by the behavior of the program, I can say that it is extremely efficient. On the other hand, it is important to mention that sound capture is a key part. A microphone with particular characteristics is required. It is actually a vibration sensor. In other words, it must capture the mechanical vibrations that travel inside the watch and its case without hardly registering the ambient noise. Something I can add based on my experience is that the software is capable of extracting useful information for analysis from poor or poor sound. I encourage you to watch the next video at this link.
  4. Bien venido @MatteoB, pienso que tu entusiasmo es justificado. El programa es sencillamente maravilloso. Tanto para los que conocen de relojería como para los que simplemente admiramos los relojes relojes mecánicos. Qué parte del funcionamiento del programa te parece más fascinante? Welcome @MatteoB, I think your enthusiasm is justified. The program is simply wonderful. Both for those who know watchmaking and for those who simply admire mechanical watches. What part of the operation of the program do you find most fascinating?
  5. Hi. I have also done tests with the program and I find it very good. However, like you I have not been able to contact the creator although he uses the social network on instagram. I would like to have the program in English or maybe even in Spanish which is my mother tongue.
  6. Thank you PeterM. I am not an expert but I can say that something can be applied. GPS can be used to calibrate the Watch-O-Scope software. It would be much more accurate than what is achieved with a good quality quartz watch. The sensor also attracts attention although you cannot see what it is. Thanks for sharing.
  7. Gracias @svorkoetter por el increíble software que compartes con nosotros. Ya empezamos a usarlo. Thanks for the incredible program you share with us. we will start to use it.
  8. On the digital filter to be applied, anyone will improve the signal. I think that will depend on the sound of the clock itself. Although personally I think the Wide option is better (160Hz - 16kHz)
  9. I'm analyzing the recording. And I have some observations. The first is that I can think that some buzzing of the 50 hz network is affecting although it is low with respect to the level of the signal. But when analyzing the gradation, in the second 26 drastically disappears a buzz that corresponds to very close to 90 hz. By doing so, the signal is cleaner. If you can determine what causes it, the signal will improve. I get the feeling that the stand of the microphone is not sufficiently padded and the vibration of table or desk that could be the vibration of the fan or the hard disk are transferred to the microphone.
  10. You also did a good job of shielding the peripherals of the microphone. That's where the signal is disturbed. Due to the level of amplification any parasitic noise, it would also be amplified.
  11. Good job Eland. Excelent sound. I have already done an analysis of the waveform and it is excellent. It's like music to my ears. I think that with that level of sound and editing programs can do a good job. Congratulations.
  12. Good job Eland. Congratulations, you are doing a good job. And do not despair about the broken discs ... I have already lost count of how many I have destroyed, due to excessive heat, excessive force, etc. It could be that my response is a bit hasty, but I'm sure you do not need any of the devices that you indicate in the links. they are all POWER AMPLIFIERS. And what you need is a pre-amplifier. And seeing what you used in your project, I would consider that what you need is accurate and nothing more. It is possible that some modifications could be made but they would be minor. I would like to ask you to share an on-screen capture of the waveform to determine the level of the signal you are getting. I send you an example of what I am requesting.
