Hello friends. I hope the moderators will forgive me, I just do not know where this can be published, but a little later, I hope here will be a real tutorial. I got the idea to build a new controller, but only to make it better, more convenient and more reliable, especially in maintenance, than the one that I have now, because now I have optical switches, but they are canopy, on snot, working good, but they needed veeeery long time of calibration and that time when I needed to disassemble buttons - I cannot assemble them again for a long time, because I lost order, to which button which switch (sorry for the pun). So I understand that I need to think, to do something with it. I really want to use the original Sanwa OBSA-LHSXF-LN, the only problem is their rather high price, especially for me. In this all, perhaps, it will also be your personal interest, since if I succeed, then you can also use all these developments in order to install it in your controller. What exactly do I want to do? I want to completely repeat (clone) the OBSA-LHSXF-LN by 3D printing the outer casing and the inner PCB of the device, since I am sure that the board inside is elementary and there will definitely not be much difficulty in repeating it, the outer casing will be more difficult. But I have a few fundamental questions that accumulated about this case: Some time ago I wanted to buy one OBSA-LHSXF-LN on Rakuten, but did not have time and the store closed. Where I can buy it now? Who knows other places? Does OBSA-LHSXF-LN fit into an ordinary Chinese button? (like this on photos bellow) In theory, it can be installed and work, but again, may be anyone have experience? I need more accurate information on this issue until I have my own OBSA-LHSXF-LN. (Sorry, I do not know why, site do not want to upload my photoes, so here it is on my google photoes here and here.) If anyone already has OBSA-LHSXF-LN and you could very much help me if you disassemble it and show me what it has inside, in order to approximately understand its contents and components. Can someone help with this? More detailed view of external case parts. It feels like there was another question, but I forgot which one .. :)))) But if I remember, I will add here. If, nevertheless, the above questions will be solved, if I get my hands on one OBSA-LHSXF-LN and if I can repeat it - materials for 3D-printing and gerber-files of the PCB that is inside, for the production of the PCB in some Chinese factory (or maybe even for self-production at home, everything will depend on the complexity of the board, but I do not think it wil be difficult) will be published by me here and you can use them. Source-files will of course also be available. It seems to me that this is a completely feasible task. What do you think?
