    Quoted from Soulrider911:

    I went to the run dmd site and seems they are all sold out? Anyone know where I can get the board. Would love to make one of these thanks

    Send them an email they may be making more... they were out when I was looking to build and they told me more were on the way.

    I have a run DMD clock that looses time, anyone else have this issue and know how to correct it?

    Is there a way to get wifi working and sync with a time server or something?

    Thanks

    Sounds like it’s got a dodgy RTC if losing time or battery dead

    Mine kept having issues with animations. Then I realized there is a small lithium watch battery on the back. Change that out and it may solve your problems. Mine works like new now.

    Well, I'm back again.

    Don't expect anyone to remember my issues, but if you're inclined:
    https://pinside.com/pinball/forum/topic/run-dmd-the-most-amazing-clock-ever-released?tq=&tu=Beatnik-Filmstar

    Long story short - my clock has repeatedly had issues with dead pixels resulting in lit vertical lines. DMD modules replaced twice, fixing the issue briefly only to have new lines go out within a week or so. Power supply replaced to no effect. Single pixels remaining brightly lit even when the clock is off. When I last posted, the final suggestion was to just swap DMDs.

    Which I eventually did a while back but life got in the way and things sat for the past couple months. I finally assembled the clock this week and brought it to work. Things seemed great for a couple days. Just got to work, clocked turned off but of course - once again I came in to one bright pixel lit even though the clock is off. I turned it on and as expected - one vertical line faintly lit up yet again.

    Would really like a working Run DMD. Any new eyes on the thread have any suggestions? I don't really expect a replacement after a year plus, but I'm having a Hell of a time accepting that it's anything other than a bad Run DMD board. Every other component has been replaced at this point and the issue continues to happen.

    #1460 2 years ago

    This issue can occur if you are using a micro-SD card. If you are, then replace it with a full-size card. Try to get an 8 MB card. You’ll need to copy the data to the replacement card using the same method that you originally used.

    Does the issue go away though if you use a different SD card? I'm challenged to see how the type of media could cause a pixel to go bright on a DMD. I've got a couple of vertical lines out on mine because of this and have just lived with it. DMD was fine when I put it in, I always chalked it up to the cheap power supply I'm using, it hasn't gotten worse though.

    I bought a spare controller for troubleshooting.
    They arent too expensive and really help since you can swap it out or just build another clock!

    #1463 2 years ago

    there are issues with corrupt SD cards and the issue can start when your clock is running and then power suddenly goes out - black out or power killed to the house suddenly. The program is actively running from the SD card every few seconds so can be corrupted if the power outage is right at the animation change. The corruption can cause lines out, merged graphics, time resetting, image lockup.

    Been using the micro SD card that came with it. There's no way to use a full sized card that I can see - the slot itself is micro SD card sized.

    In my case - the animations aren't corrupt at all. Everything runs fine. To my knowledge I've not had any power outages at any point while using the clock. Something is killing dots in the modules on the DMD itself. I've not had the clock run for more than a week or so at a time without having a dot go out eventually.

    While it sucks to see that someone else appears to be having the same issue - I'm a little glad to see this to make me feel like I'm not going insane. I'm an absolute layman at best, but I fail to see how using a microSD card vs a full size card (which I have no way of plugging into the board) could make a single pixel light up even when the clock is turned off.

    Out of curiosity I just removed the microSD card and plugged the clock in. The latest random pixel lights up immediately. If I turn the clock on it displays the time without any animations (as expected) and the line containing the single lit pixel lights up.

    I had a sorta similar problem but it was a column.

    I swapped out my trusty spare controller and it was the same.
    Swapped ribbon cable, it was the same.

    Swapped out the display panel and it was fixed.

    I also had weird random nonsense on the diplays.
    I swapped everything and it was the same.

    Turned out to be a failing AC adapter.

    I swapped it out and its all perfect again.

    Well at this point I've swapped out individual DMD modules twice, the ribbon cable, AC adaptor and then finally swapped DMD panels. Replacing the modules and entire panel "fixed" it temporarily, but here I am with another dead dot and a vertical row lit up on my clock that somehow sends power to the display when turned off.

    The only thing I haven't replaced is the board itself. Not only do I not have another one, but they're not available on the site and frankly I'm really not inclined to buy another if they were.

    I suppose I'm pretty much just venting at this point, so my apologies to anyone reading this. Just wanted a cool clock and appear to have gotten a lemon.

    When you say DMD modules replaced twice, did you replace segments on the Stern dmd, or just the entire panel? Only reason I ask is the Stern ones crap out quite a bit. I have some spare working ones that you could try out and see if they last.

    Individual 8x8 modules replaced twice. Then swapped to an entirely different panel.

    I probably have one laying around. May as well give it a go. Though I'll eat my hat if a micro SD card is somehow responsible for the panel receiving current while the clock is turned off considering that it happens when there's no SD card inserted at all.

    Let me know how that goes, I've got a hat handy here I'll eat too if a card swap changes anything.

    yes as the program is effectively on the SD card so it isn't a matter of dumping the images on it needs to go through this process which is a pain and not apple mac friendly

    I’d try a different card reader, a different memory card and a different computer to rule out any random incompatibility with the software/hardware combo. Also try a different disc image just in in case there’s an issue there as well. Good luck!

    #1481 2 years ago

    The B134 img has been used many times and I haven't changed anything at this link
    https://swinks.com.au/manuals

    Did you unzip the file and just select the img or imgc file type
    - could be selecting the incorrect file as it says the zip file unless it is referring to the folder - haven't done it a while
    - could be the SD card being corrupt

    I tried updating my clock with the B237.img and it would not boot. I was able to return to the B134 image with no problems.

    Does the latest B237 image only work with certain run-dmd board revisions? How many animations are included in B237? I notice the uncompressed image file is about 4x larger than the B134 image. B134 has 2302 animations when I browse it through the run-dmd board menu.

    Sorry I can't really help as the file was shared with me - I was told it would work on the DMD - White board.

    What board is yours?

    I did notice the file type difference:
    B134 - is a imgc
    B237 - is a img
    so not sure if this affects the end result

    Not sure what board I have at the moment, but it's Rev h3. I converted the original B134 imgc file to img format using this tool on GitHub: https://github.com/Shizmob/unimgc

    I'm a mac user, so I just use dd to transfer either image file to the micro SD card. So I tried the same dd command format for the B237 image.

    Ok, I will keep checking there. I get an error message when attempting to sign up for the notification when back in stock.

    Quoted from DanT:

    I tried updating my clock with the B237.img and it would not boot. I was able to return to the B134 image with no problems.
    Does the latest B237 image only work with certain run-dmd board revisions? How many animations are included in B237? I notice the uncompressed image file is about 4x larger than the B134 image. B134 has 2302 animations when I browse it through the run-dmd board menu.

    I have the same issue. I'm guessing my board is too old? I know my FW is 3.55 (Run-DMD Type C)

    Ok some testing was done though not by me, but someone experienced with these clocks that asked me to post this to help the community.

    These are the test results:

    1. Tried both B237 and B134 - IMG & IMGC File type did not matter, both worked
    2. Tried in 4 different Run-DMD clocks (Classic with updated firmware and Exp-one, Pinball MK2, Pinball Original, White) - The above file types worked on all these boards.
    3. Did all of these tests on both software - Etcher and HDDRawCopy1.10Portable - This did not matter but HDDRawCopy was way faster.
    5. Tried a bunch of cards - This appears to be the problem when it doesn't work.
    6. In most cases where it worked I had to hold the "3" button to put the controller into setup mode. IF the display goes into the slow blink mode the card will likely work but you have to wait 20 seconds or more to get anything to display. IF it's a normal blink the card will likely not work.


    Here's a summary of the cards that worked.
    1. 8GB Kingston MicroSD
    2. 16GB Microcenter MicroSD (US PC Store)
    3. 32GB SanDisk MicroSD
    4. 32GB Kingston MicroSD
    5. 32GB Kingston SD - I had 2 of these. They came with recent Run-DMD boards.


    The following cards did not work.
    1. 2GB Transend SD - Note that B237 is too large for a 2GB card.
    2. 4GB Transend SD - I had 2 of these - Neither worked.
    3. 8GB Transend SD - I had 4 of these - None worked.
    4. 16GB Microcenter MicroSD - I had 3 of these including the one that worked above. They appear to be identical.


    Conclusion
    It may be worthwhile to try each of the cards that you have until you find one that works. If buying a new card a newish Kingston 32GB card seems to be the most likely to work. Fortunately these aren't expensive but may take some trial and error to find one that works. Odds are very high that other cards will work though.


    In Summary
    Both files work on most dmd clock boards but the weakness is the SD card brand and memory size.


    Hope this helps

    This is really helpful testing! I recently made two clocks for both myself and my dad with the mk2 run DMD and stern displays. On mine, there were absolutely no problems. On his, the animations would be corrupt after about a day.

    That happened even after reflashing the SD card, so he ordered a new one and it has been fine ever since. We both started with the same original SD card that came with the kit, but maybe his was part of the bad batch? They were both Kingston canvas select Plus 32 GB cards. I got him a replacement card off of Amazon, I think we ended up with a SanDisk ultra and that hasn't had any problems.
