  1. hi, so I have posted here before about my interest in the mosaic display and I have shared some 3d models in the past. I just wanted to share an update to share my progress and ask for any feedback. I have been trying to design my own version of the r142a destination and route tile. I have started with modelling an led shroud and the PCB for addressable LEDs. https://imgur.com/a/yWxRTHr I haven't yet ordered the 3d print or the PCB from jlcpcb. just wondering if I could get some feedback on if I made any mistakes so far. I havent begun programming this yet, which I know will be a nightmare because 1. I don't have proper images to go off of for what all the letters look like 2. its an 88 segment display so I need to determine the state of all the segments for every digit. I have designed this prototype to be 100 by 200mm, its kind of arbitrary, I should have put more thought into it but I just wanted to get started on a first prototype to see how things would look.
  2. hey, I want to make another update with a more finished version of the 3d model. the Idea behind this is to illuminate the segments of the mosaic design with addressable LEDs. I am not sure if this should go in another thread. I don't have a 3d printer but if anyone does, you can try printing this or you can modify the code to adjust this part for whatever you like. https://cadhub.xyz/u/Radoka/r142a-train-route-tile https://cadhub.xyz/u/Radoka/R142a-destination-tile let me know what you all think!
  3. links may have broken: https://cadhub.xyz/dev-ide/openScad#fetch_text_v1=https://github.com/angryseptagon/random_openscad_creations_I_made/blob/main/train_display_stuff/mozaicdisplay_openscad_square.scad https://cadhub.xyz/dev-ide/openScad#fetch_text_v1=https://github.com/angryseptagon/random_openscad_creations_I_made/blob/main/train_display_stuff/mozaicdisplay_destination.scad
  4. I just wanted to update this thread with the destination sign I made and posted in another thread, as well as provide cadhub/github links: destination tile : https://cadhub.xyz/dev-ide/openScad#fetch_text_v1=https://github.com/toastedice/random_openscad_creations_I_made/blob/main/train_display_stuff/mozaicdisplay_destination.scad original tile I posted: https://cadhub.xyz/dev-ide/openScad#fetch_text_v1=https://github.com/toastedice/random_openscad_creations_I_made/blob/main/train_display_stuff/mozaicdisplay_openscad_square.scad
  5. I didn't know there were so many different mozaic displays, I used your design to make a rough model/drawing in openscad using my old code for the route sign, but I realize that its completely different from what I remember/recognize. I didn't realize that the different destination signs were so different. my one doesn't look right but idk. https://imgur.com/a/6mmpPoX
  6. That's really interesting, I have made a model of the route tile, but I have never seen the destination tile like this. did you make it yourself? the arcs look a bit different. I think the deisgner of these mozaic displays used the same kind of arc everywhere and some of the diagonals look off. though cause of corona and being unemployed I haven't seen a destination tile in person in a while. but this is a very interesting recreation. I like how you got the horizonal and vertical line thickness right.
  7. nice! if you can point me towards destination tile reference images maybe I can make a similar model for that if you want.
  8. I put it on thingiverse if anybody wants it. https://www.thingiverse.com/thing:4785826
  9. sorry, thanks for the help though. I can't tell if all of these segments are necessary, I wish I could have a clear reference. Its not much but I found a website where I can share the model so far: https://thangs.com/m/12000. I might drop this project since I do not have the means money or energy to finish this, maybe someone else here might find it useful.
  10. is it possible to include to include the "█" as reference to see what these displays look like when they are completely on?
  11. I think I am just trying to model the route tile, I think it looks the most aesthetically pleasing. could you tell me where I could find the font if you know? here is my progress so far (https://imgur.com/a/w1ngIpM) though I might abandon this project (I don't have the means to do much beyond some light 3d modelling since I am using linux and have no time, money or 3d printer) it still seems interesting.
  12. made an instant.io link. it works if we are online at the same time, and I am seeding. https://instant.io/#1ceb3366d7409b62af84aae6e913befbe0f41adb
  13. I have been looking into the R142A Mosaic LCD, I think its a really interesting and unique display. I started making some cad designs to try to replicate the display with addressable LEDs. I don't know if I have the energy money or motivation to continue the project, but I wanted to share what I have and learn more about this unique display. reference photos and fun facts appreciated. actually I am new to the forum, and I am unsure how to share these CAD files on here so I guess the best I can do is an image of the sketch I made on freecad. I also have some old cad stuff I made on solidworks but I don't have an easy way to pirate a copy and then install it on linux. :(. I put the files up on volafile, they will expire in 2 days but its the easiest way I could think of for now. https://volafile.org/r/1mw4h567r
