    extra movie, but a small note on the shield (cyberblatt) no indication of hours 3, 6, 9, 12 or 12 itself. Because I do not know how to get a handle on the chair.

    The plate rotates around 60Hz. With the naked eye, you can not see this twisting darker section. As already mentioned, this is due to the specific factor fps of the film being recorded.

    bad for those who do not know how to read it and have no practice. ; (

    Of course, your children (as they will appear) will not teach you "know your watch" on this particular device :P . But by the way, a lot of stylish watches, even if on hand, do not have any hour markers on the f erblacie. In several display modes, you can see additional markers that make it easier to read the time with a less-than-trained eye.

    And I have a question, what's this remote control?

    And such an additional question, you said that you applied the counterweight, could you present it in a photo?

    Universal remote available in many places, personally I bought it on Allegro, average price 7-8 PLN.

    As for the counterweight, I made it as I mentioned a piece of the Super Glue sticky CD. Dimensions cut to the eye. Vibrations almost completely eliminated (sorry, for the quality of the picture, but the camera is temporarily missing)

    How did you cut the PCB? I see that it is very nicely cut despite the complicated shape, so the method must be good, it will be very useful for me (Shears are passÚ) ;)

    Simple cuts were made using a homemade mini-circulation based on dremel. Its design is so sultry that I do not have the courage to show it here, but with a little practice it gives good results. ;) . Curvature pre-treated on a large two-blade grinder, and then also a dremel, this time with the grinding stone already in place instead of the disk. Dremel was caught in the rack, which increased the precision of work, I could rest the plate on the table and operate with two hands.

    can you provide links to MARITEX for these specific diodes?

    I do not know if it is in accordance with the regulations of this section, at most I ask the moderator to censor the "harmful" content.

    I have a small question whether these LEDs must be attached to these boards or can they be connected normally without these plates ???

    these LEDs filled in with something that are flat on your photos?

    The project has been linked to hackaday.com, people ask for a description in English :)

    I warn you that I'm not the author of :P

    The diodes can be connected without any plates (there are no electronics on them), however, the plates are more comfortable ;)

    EDIT: Electronics however, is ;)

    there are some black male, marked 820, 820 and 151 .... how is it called?


    you could just give what parts you used to do electronics ...

    Nice idea and great performance.
    But that's how I wonder how to make tips different in length ...
    Anyone have an idea?

    Hello,
    Diodes are much easier to mount on plates than "in a spider". I have not filled them up, they have such a factory silicone pickle.
    Creator , what you ask is probably resistors :P .
    So far I have no idea how to make the tips different lengths.

    It seems to me that a second set of diodes from the side of the rotor would be useful and separate them with a spacer, a mirror reflecting as if the light from external diodes does not fall deeper than on the spacer and the same with the internal diodes that would be around the rotor. The only thing to do is to synchronize them programmatically and you have minute and hour hands of different lengths. I hope that I have clearly described my vision.

    Somehow I can not keep up with your construction :D . However, I do not think that he will continue to develop this project, I prefer to sit down on something new. Nevertheless, I have a fondness for devices like POV. I think that when I collect the funds and the necessary knowledge, I will try to make my own device working on a similar principle to that

    Elements were purchased in TME, diodes in MARITEX.


    The TDA 5410 system is not in TME

    A In fact, I apologize for not really the real information, TME withdrew it from the offer. Nevertheless, the chip I used was purchased from TME, except that two years ago to propclock . This means that propclock stopped spinning so that HDDClock could :P .

    Is it still possible to get it where yes, but at a reasonable price?

    What is the speed of the HDD motor in this project?

    Just the lack of a reasonable price from the suppliers forced me to start the old project and pull this driver out. :( . It is only to look for and look for some occasion.

    The motor rotates at 61Hz. :)

    It worked very well for you. I have another question, you can sell 1 or 2 tiles for this because I really do not want to do tiles for this. Or maybe someone will do it, I would like to get a chance to catch a play or two. Of course, for a fee.

    Unfortunately, I made only one PCB. But thanks to the documentation, you can commission a professional company that will do it better and not so expensive.

    Or maybe there is a replacement for the TDA 5410 system? Or is it possible to replace it with the appropriate uC driver? Finally, we check the speed of the proximity sensor.

    Hello
    I have a question about the MARITEX company because I want to make purchases with them - for example, the example LEDs that you provided:
    HDDClock - clock from hard drive
    I marked it in red - it is written that the packaging is 2k - that is when buying from them I have to buy a minimum of 2000pcs, because these are packages or sell diodes for individual pieces? Or maybe they sold you a few pieces by way of an exception?
    As for the different lengths of individual tips (although different colors of instructions are acceptable despite the same lengths) - you would have to cut slots in various lengths (eg every 120 ░) and change the software. There remains the question of construction - that the gaps are not illuminated by each other.
    Nevertheless, I like this clock more:
    HDDClock - clock from hard drive
    He has more possibilities. When using RGB diodes with a larger amount on the arm, you could get a similar color effect as on this HDD. How else would you apply a slightly tarnished glass ... the effect is virtually identical. So give him that scalpel quickly, let him spin :!: :D
    Greetings.

    As I mentioned in the first post, I did not take care of parts myself ;) . You can write to Maritex asking if they sell smaller quantities, or ask for samples. Besides, I also saw diodes with similar parameters on the Allegro.
