    Quoted from latenite04:

    Op, sorry to see that you deactivated your account but if you read this thanks for sharing. These are a cool ad on for a pin2dmd setup for only about $40. If anyone is looking for a way to hang these panels on a non metal backbox here is the mount I made up. It's made out of corrugated plastic, a galvanized metal strap and packing tape. There are three extended straps of tape that go over/under the machines dmd panel and get pinched in the backglass channel to hold it in place. I ran the power and data cables around the edge of the backbox dmd panel, the flat cables fit between the panel and the edge of the cabinet. I used one of the flat cables that came with the led panels to run power by soldering the power cables to .1 headers on either side. I'm sure this could be done in a more elegant fashion but this is what was lying around the basement. This worked for South Park and Street Fighter.

    3d printed connector to hold two panels tight together, I was getting light bleeding between the panels.

    This looks fantastic. Do you have any video showing them both off?

    Where is the easiest place to connect the 5v?

    Quoted from DugFreez:

    That would depend on the game.
    In Sega / Stern games (Twister - SAM system games), I think it would be the 3 holed connection in the front of the cabinet, on the right side near the service outlet. It's a 3 holed molex connection that has GROUND (on the pointy top end) +5V DC in the middle hole and +12V DC on the bottom hole.
    Looking at your collection...that info isn't going to do you much good...

    Hahaha. Yeah this would be for WCS and Shadow so WPC games

    So I bought the panels and installed everything today. First off it is crazy how easy everything fits and plugs in. Super easy to do.

    The issue I am having is what others have mentioned which is that the Pixels themselves are rather small and there is a fair amount of black space around and between each. With that said do you think some sort of diffuser would help with this problem. Some sort of film or panel that would go in front of the pixels to make them "grow". Thoughts?

    This actually has potential... I turned the contrast up to 9 and brightness up to 8. It actually looks pretty great.

    So I found an easier way to mount this to a wooden backboard. It doesn't cause any damage to the wood and still uses the magnetic standoffs.

    First you only have to order some of these thin metal plates used for cellphone mounts. $6

    And you will need to order slightly longer ribbon cables. $9
    https://www.amazon.com/gp/product/B07FKRYJVR/ref=ppx_yo_dt_b_asin_title_o01_s00

    Once you have received your parts, the first step is to remove the speaker plastic as it will show around the edges of your display. I think black looks better around the edges. IMG_8032 (resized).jpegIMG_8032 (resized).jpeg

    Then you want to attached your sticky magnetic plates where the magnets are going to connect. I cut a few in half using tin snips. IMG_8033 (resized).jpegIMG_8033 (resized).jpeg

    After you have the front taken care of you will want to add some space between your LED screen and the wood so that the wires can run through it easily. I used some washers but you can really use just about anything. IMG_8034 (resized).jpegIMG_8034 (resized).jpeg

    Next run your ribbon cable and your power cable. You will want to plug your ribbon cable in the same spot the original was plugged. I added a molex connector on the end of my power wires so I could use the same molex header pins the original used. IMG_8035 (resized).jpegIMG_8035 (resized).jpeg

    After that reinstall your speaker panel and then plug everything in on the new LED panels and you should be good to go. IMG_8070 (resized).jpegIMG_8070 (resized).jpeg

    I love the way it looks. I turned up the contrast and brightness which helps with the colors. I have already ordered 2 more panels to swap out my other games. Good luck!IMG_8071 (resized).jpegIMG_8071 (resized).jpeg

    Quoted from Toppers:

    Shipping seems to Be outrageous. We should get a group Buy going. What are you paying for shipping? Are you using the original link from OP?

    Shipping was only like $8 per panel. So for two panels plus the shipping it was like $35 total.

    Here is a video with it off and then some more gameplay.

    Quoted from Dmod:

    I think the LED setting on the ColorDMD is reversed for those LED modules. Please make sure the ColorDMD menus appear in orange (and not magenta) for the intended colors. If it's not appearing correctly, you can flip the LED setting between RGB and RBG to swap the blue and green color channels.

    You are 100% correct! I can’t believe I didn’t notice. I was too focused on the size to notice the color change. Thanks for the heads up and the amazing products!
