    Re: Open source timing software.


    Thanks a lot, Ocram, for testing on newer Windows systems, and also for
    your "like" and your review. I have a penchant for doing idle blah blah on
    this forum, so you will excuse me if I take your screenshot as an
    opportunity to indulge.

    You pointed out exactly the kind of use case that I had in mind! Cheap
    consumer mic, and a diver case that, I believe, does not help. If we
    imagine an absolute beginner, he will almost invariably be more or less in
    such conditions. At least I was in these conditions (and I still am an
    absolute beginner at best). The only option that one can trust and does
    not involve some form of commitment is to use generic audio editing
    programs like Audacity. This method is sure, but so slow and boring that
    even I (despite being thorough _and_ slow) became discouraged.

    Also one can see in your screenshot my other reason not to include a
    numeric display for the amplitude. When the audio is bad, it might be
    still possible to get the rate and the beat error, but the amplitude is
    often lost because the first pulse is to weak to come through the noise.
    The user can read the graphs and decide very easily, but, at least for me,
    to design an algorithm that reliably does that is a nightmare (or perhaps
    a dream). And also pointless, because the user can do it better than the
    machine anyway.

    Re: Open source timing software.


    Hi my friends!

    Just a little update: I fixed a bug in the algorithm that prevented it
    from locking in some situations, and I made a small change to the
    interface. Download link, the same.
    http://ciovil.li/tg.zip

    I really appreciated the enthusiastic reviews of Klaus and Ocram (Marco?),
    however I would like to find the remaining bugs and call it v.1.0. So
    anyone who tries it and is dissatisfied will have my gratitude if he drops
    a line, even by PM. Any critical opinion is welcome. (However please
    update to the latest version.)

    By the way, I am becoming addicted to test every random watch from
    Youtube: it makes even a noob like me feel like I have the elusive BCB.
    And you don't get this with any other program! For eye-candy, here you
    have one with birds, I suppose, and severe positional variation.

    Re: Open source timing software.

    Hi Contrate_wheel,

    Your program looks neat. It might have been a different thread, but I think you were suggesting compiling for OSX would be trivial.

    Could you post instructions on how to do this? I am running OSX 10.10.4 if that is of interest.

    as i said could you add the amplitude even the average one, that would mean a lot to the more serious hobbyst's .

    Experience on watch movements repair:

    modern swiss movements: 5
    japan movements: 3
    older movements: 2
    chinese movements: 0


    According to above experience grades(smallest 0-5 highest) my advice can be incorect or completely out of mind, so beware and take my advices with caution if the grade is low!!!

    I can not write instructions because I don't have a mac to experiment with, but, if you want, let's try it!

    So, you need to be able to compile C99, if you have make and pkg-config things will be easier, and you need to link with gtk+2, portaudio2, and fftw3. There are multiple ways to achieve this, either installing the development tools and libraries sparately, or using some distribution that packages all of them. When I had a mac (centuries ago), I used FINK (Fink - Home), and they seem to be still alive.

    In short, you need (1) being confortable with the command line, (2) a working development environment, as in "beeing able to compile hello-world", (3) it's better to have make and pkg-config, (4) gtk+2 -- version 3 might also work, (5) portaudio2 and fftw3.

    To make progress I need to know at which step you are...

    Thanks, you made me reconsider my design a bit.

    As Klaus demostrated, the amplitude is there, it's just not written as a number. For instance, in the screenshot above (pretending that the lift angle 52 is correct: I didn't look it up), the amplitude is about 155 deg.

    I have three questions:
    1 - Did you try the program on your setup?
    2 - Was it hard to read the amplitude from the graph (if yes, screenshot or even better sound sample would be appreciated)?
    3 - Why do you feel that the number is better than the picture?

    The third is not a rethorical question. Users are king, so if users really prefer a number, then I will see what I can do to get it!

    I have three questions:

    2 - Was it hard to read the amplitude from the graph (if yes, screenshot or even better sound sample would be appreciated)?its very difficult to spot it and to a beginner it would be difficult and errors might occur, numerical values are what the people are used to (from other timing softwares and machines) and would prefer, rarely anyone sees the soundwaves, especially if there is no very difficult defect to find
    3 - Why do you feel that the number is better than the picture? in working environment there is no time to analyze the picture

    The third is not a rethorical question. Users are king, so if users really prefer a number, then I will see what I can do to get it!

    @Emso

    Thanks, makes sense. I will see if I can get a more or less reliable number, at least when the audio is good.

    @1 setup as shown in first picture
    @2 let me say ... depending ... I tried to add some soundfiles to show you why, but have not been able to upload them
    @3 to have an unreliable number is not as helpful as a reliable graph. I prefer to decide by myself if the amplitude can be read from the raw-data. An additional value in form of a number would be fine.

    This screenshot is a combination showing both, your timegrapher and biburo.

    The signal from this watch is quite good, even if the caseback is still closed. Reason might be, that the movement is fit directly into the case without a casing-ring made of plastic.

    A Promaster with closed caseback gives a weak signal and therefore I would not trust an average amplitude value. To get an even better signal I usually open the caseback and contact the pick-up-clip directly to the movement, which will give a stronger signal, therefore allow to reduce amplification and consequently reduce the noiselevel.

    Maybe I'll think about servicing this watch some day (at least adjust the repére).

    Thank you. I was actually asking these questions specifically to Emso, yet your answers are very welcome!

    I agree with you. I will try to add a numerical value, without subtracting anything from the current design. As you see, one needs to devise an algorithm smart enough to decide whether the numerical amplitude is reliable (and then show it) or not. I have definitely to think and experiment, but it would be stupid not to try.

    Your sound samples would definitely help me immensely. In particular the good ones. By the way, if anyone is interested in contributing to this project, real world samples are the thing that I need more.

    I don't know how to upload them on the forum, if possible at all. As you can see I am a noob. You could put them in Dropbox, or somewhere else on the public internet, and post a link. Feel free to PM if you don't like posting it. I will also send you my e-mail by PM, so you can e-mail them to me, if you prefer. If you can, use an uncompressed format (zipped .wav is OK), and take at least 30 seconds.

    Thanks again!
