  1. Ah, for testing. Then I will leave it out. If there is more feedback or questions, also from other people, feel free to post.
  2. Ok. But you also have this jumper in the EVO HD design. I just copied it. It's in the same way connected as in your design: in off the signal goes through the LS123, in on the signal takes the shorter route overruling the LS123. Please see attatched picture. Maybe you could clarify this for me. Alright. I don't trust the chinese XL4015 designs either. But the adjustable voltage may become it's handycap, so good point. Let's not use the MINI560. Because referenced to the V4 shield design. But yes, it's better to name it V1.0 HD shield. Thanks.
  3. So as of now I have 2 versions of my shield design. I have included some pictures of the 2 boards. The difference between the two are the DC-DC converters: The first one includes the larger DC-DC converter (XL4015). The second one has a smaller MINI560 DC-DC converter. This MINI560 is cheaper, but not adjustable (maybe better so you won't fry it with the stock high voltage?). The boards are 120x120 (same height as the LED panels). The ribbon cables for the LED panels should connect to the lower left and lower right corner connectors (HUB75E1 & HUB75E2) with the included ribbon cables from the panels. The power wires should be cut to length and soldered to the 5V & GND pads on the left and right side of the board. I also included 2 SD card designs: the chinese one from the normal V4 shield and an adafruit one: https://www.adafruit.com/product/4682. So people can choose what to solder on. I would like to get some feedback on the designs so I can decide which one to publish. Also if there are questions, feel free to ask them. P.S. the boards can be made cheaper at JLCPCB (I have great experience with them), so the 120x120mm dimension should not be an issue in my opinion.
  4. This is some usefull information! I will remove those components/connectors. What about the RS232 and 3V3 TTL headers? Also I put the SWD header on it just in case, but I don't think this is needed?
  5. The idea was to put the shield in the middle of the two displays and then connect the power wires and ribbon cables to the shield. I attatched a picture of what I've got so far. Also the 74HCT245 are quite big in through hole version. So it would be universal in that sense, but bigger because the DC-DC converter is build on. I get the feeling there are not alot of users that change the layout of the Eagle files, so that's why I wanted to create one with as much features as possible, so this display HD will be more created. But I could make a 100x100mm shield if people would like to DIY. Would like to get more feedback on the current design.
  6. The previous versions where screwed straight to the displays mounting holes with acrylic panel between. I would do the same, but these panels are larger. So it would get bigger to mount it to the corner mounting holes in the panel. I thought it would be nice to include the DC-DC converter on the PCB, because it would be bigger. But you're right, then it would cost more. But as it is a DIY PCB I thought you could also buy it at another PCB manufacture like JLCPCB. Also as Terranigma mentions it will not fit DE machines. So do you both think a 100x100mm is a better idea and then the DC-DC converter still separate? Or maybe 2 version with and without DC-DC converter build in? Whatever version I make, I still need the dimensions for the panels so I know the mounting holes of the different types.
  7. I don't know if this is the right topic, but I think it is the best place to start. I'm in the process of designing a shield for these types of displays, to give a cheaper alternative to the EVO HD board. I will publish it for the community. It features the layout from the DC-DC converter PCB, so you won't have to buy that PCB separately just add the DC-DC module. And the WPC molex terminal and 2x screw terminals (8V-36V & 5V input) for easy connecting. I contacted the chinese seller for the dimensions and got them (P1.875 display.jpg, lowest picture). But it seems like the chinese have different variants for the mounting holes on the LED panels. I already know there are 4 different versions and have attached pictures of them. Maybe there are more. Because I want to design the shield for as much variants as possible, I would like to ask the people in this topic who already bought the panels if you could measure your version and give me the dimensions. Hope you all can help me. Thanks. -René
  8. The above sums it up nicely😃. Just to mention one more time: If you have a Data East or Sega machine with a 128x32 plasma DMD or a 128x32 PIN2DMD EVO board and would find this a useful project. Just leave a comment. Because we also want to make sure that (besides the challenges mentioned above by @Terranigma) there is interest in this project. -René

  10. For Data East CN6. For sega Whitestar and Stern SAM J16. Double check orientation. -René
  11. Hi Antonio, They are asking for the text like: X1, X2 etc. I did not put these in the BOM, because I believed no one would let it be made by PCBWAY. I did create a BOM for you how they are expecting it for manufacturing (see attached file). Hope it works. -René BOM PCBWAY.xls
  12. As more people are asking for gerber files and even suggested to make a shared project on PCBWAY for easy ordering, i've decided to make a shared project on PCBWAY for it: PCBWAY LINK I'm also uploading the gerber files here, along with an updated version of the PCB Autodesk Eagle files. The BOM remains the same. @lucky1 Could you also update the design in the hardware folder for me? I hope everyone can order faster now without hassle :).

  13. Eagle should ask you if you want to open both the schematic and board together. So click on the board and select 'yes' when Eagle ask if you also want to open the schematic. The gerber can be made from the board when it's open. You can use this instruction: How to Generate Gerber and Drill Files in Autodesk Eagle - JLCPCB: Help & Support It will export the files and as an advise: Set the checkmark at 'export as zip'. This will give you a zip file you can put straight into the uploading path of JLC or PCBway.
  14. Thank!. Yes, you need the gerber. As lucky1 said you can export the gerber in eagle. You can choose the standard "template_2_layer" cam processor as this one is good enough for this purpose .
  15. I just picked up my pinball hobby with the led displays again and I realised it's been a long time. Then I saw I never responded to this topic. So my apologies. I'm happy to share the PCB design (Eagle) for the breakout board and give something to the community :). If @lucky1 wants to put the design in the hardware folder on Github, I would have no trouble with it. Data East converter.brd Data East converter.dru Data East converter.sch Connectors BOM.xlsx
