    Well, it hurts ... 128 is not cheap ... I wonder if the other elements are alive ...
    If you can not measure the resistance, connect any three wires. Two are definitely OK. Connect the voltage + 5V to 4 and 8 TDA and, of course (-) to the whole system. How it works is OK if you do not de-sold one - and change it with a free one. If you postpone the right move - if it does not return to its place and you take the next one, etc ... In the end will move.
    TDA are quite robust (although it seemed to me that the processors too - not once I connected the voltage backwards but only for a moment).

    I bought the Atmege programmed, but after connecting to the 5V board, nothing moves except the LEDs light up in blue; / what can it be?

    Show how you have set fisebits. You may not have turned off Atmega103 compliance mode (M103C)

    Yes, I have Fusebits set up, so what can it be? ; / I am asking for advice what I am doing wrong; /

    Good question :)
    Start by checking if 51 is + 5V on the leg - remove it from the TDA stand before checking it. If after 5V the supply voltage appears and the motor does not start, it may mean a TDA failure or incorrect connection of the motor terminals. If the engine is badly connected, you should hear a squeak or the engine should start to "shake". Lack of tension on the 51st leg can indicate:
    - incorrect uploading of the program
    - processor damage
    - quartz damage
    Earlier in the post you have test programs - try to upload them and see if it works on them.
    If you have an oscilloscope or at least some logic analyzer, see if you have a square wave at f = 4,096 kHz on the 7 RTC leg. If it means that rtc is most likely OK - the lack of a signal may indicate:
    - RTC damage
    - processor damage
    - incorrect programming of the processor
    - no communication on the processor lines - RTC
    Desolder MAX - it is unnecessary to start the system.
    Check the entire plate under the magnifying glass for short circuits.

    On the 51 leg Atmega is 5V, the motor does not move, I tried with the other motor from the disc effect the same; / after the test programs the diodes blink :) so the rest I think it's ok? :) it remains to replace TDA and hope that it will start :) and the question is whether the universal remote is needed to run the clock? If so, how to run a watch without a remote control?
  • mlassota

    The watch will start without a remote but ...
    - the watch can not be set
    - it is not possible to change the display mode
    - it is not possible to turn the watch into stand-by mode

    It can be any TV remote control broadcasting in RC5 - some Chinese counterparts from Philips remote controls are great.
    You can also make a remote control yourself by writing a simple program, eg in Bascom on a processor such as AtTiny 2313
    No service is very hard ...

    I am just asking for a test to connect and if I see that in general it will try the pilot :) and how do you think that TDA has gone? ; / defakto already ordered a new system :)
  • mlassota

    It looks...
    TDA are quite robust but playing with HDD motors has released two pieces, so there is a chance.
    In test programs, colors should ignite one after another and the engine should start for a moment. If he did not move - he did not even murmur - there is a chance that TDA fell
    How do you get TDA, do the same driver on the contact or universal board and connect to the engine ...
  • hacker_ice

    Level 24  
    I put in a new TDA chip and the engine does not move; / question if it should go to power with USBasp?
  • mlassota
    Level 18  
    So it will not be so easy ...
    Let's start by locating the cause.
    If you have a contact plate, follow the attached diagram and make the controller layout. If you do not have a PCB, then the PCB for the controller is also below.
    How do you connect the controller to 5V - the engine should start.
    As we move on the external driver we will think further.

    PCB is prepared so that you need to solder it on the surface of the DIL18 stand with the pins bent outwards - resistors and capacitors probably you have ...

    Could anyone provide me with a pcb scheme for diodes? Unfortunately, I do not have a protel, and linux probably there is not even ... I made a plate driver for the watch but unfortunately I can not deal with these schamats.
    I would like to ask you some pdf-a :)

    I have a problem with opening the pcb file and others using eagle, I only display numbers and numbers, so it's supposed to be done if I have a diagram I've downloaded 10 times maybe someone knows my question?
  • niezabitowski

    These are files not Eagle's only Protel, probably version 99.

    Hello! You did it in the protel program, or it is possible to run your schema in another program. I can not find a protel

    Hello, I am French and I do not understand the Polish and very little mastery English! So, I'm doing the translation with Google. Thank you for your understanding.
    I wish to realize "HHDClock" which is sensational: congratulations for this realization. I have two problems: the diodes "MARITEX" are not available, can I replace them with these LEDs found on Ebay or else at "TME"? Some resistance values are different between the scheme and PCB photos: eg R2-R13-R14 = 47 Ω and on PCB = 100, R1 = 100 Ω and on PCB 150, R3-R4-R5-R11 = 10 k & nbsp; and on PCB 4.7 k, R15-R16-R17 = 10 k & nbsp; and on PCB 47 k's!
    Thank's for your answer. Best regards.

    Could someone please tell me :
    1) what jumpers need to be jumped during programming?
    I am getting the square pumping in MAX232 on the 1uF capacitors but RXD and TXD are constant 5 volts?
    I believe that the atmega128 is making those high outputs?
    2) how to configure my computer to be suitable for the programming of this chip?
    I have apsolutely no knowledge on this and Im just trying to make the hdd clock :) , as you could assume i already invested quite a bit of money to get where i am now, so i dont want to see it go to waste because a few glitches :)
    Thanks to anyone who responses :)

    Here are the images of both sides of the pcb. I know it looks horrible ( It is my first double sided printer transfered SMD board i have ever made :) ) ,but all connections are solid and there are no shorts, the clock chip is missing because i coulnd find it in an SO-8 package but only DIP-8 ,so it will be mounted somewhere in the case, and the PDO jumper isnt where it is supposed to be,but right after it goes out of the atmega,with a little piece of wire ( i will clean it up right after i manage to program it ) and mb1988mb1988 thank you very much for responding, it is an honnor :)

    Again i know it really looks bad but trust me all connections are how they are supposed to be, I've put many many hours into this board :) I've even tried the opto switch op amp output and it is good, but so far it is the only thing that works on the board :(

    Oh, where to start...

    First of all, 'few glithes' and ''horrible' in your situation sounds like a complement :P .

    What I see is unfortunately lack of knowledge and I don't think that the clock will run near soon, but with small steps maybe someday you will get this working.

    What you call 'jumpers' is in the fact 10-pin programming socket compatibile with ISP programmer which uses KANDA pinout standard e.g. USBasp. You should get one and try to comunicate with your uC. I won't be describing this procedure because it was described many times elsewhere. This step is crucial and can't be skiped.

    Yes, you are right, I am just a beginner to this, but hey, everyone was a beginner at a point :) I thought that the max232 is for the programming of the atmega :( , if not, what is it for ? :) And i will fix the pins that you said were for programming by replacing them with a proper socket :)
