Well, I have been looking into converting the gpd win ( or PSV 2000 ) analogue joysticks into clickable ones...I think the clickable part must be put either into the whole joystick package ( disasembling it and 3D printing the lower encasing so it would fit a microswitch or a dome switch ) or on top of the shaft ( with a 3D printed shaft+uppercup replacement which would fit a dome switch; in this case there would be a replacement for the now rubber cover, replaced with a cap that would cover the dome switch and it would be railed in the replaced shaft in a "for claw" manner or so, or maybe it can be rubber too... but theese dome switches need a hard tip to press the dome ).Look at theese: http://www.ckswitches.com/media/1336/ed.pdf ( the gpd win and lots of electronics have theese dome switches, but just smaller ones ).We should find some smaller one, theese are 11mm wide.Then, two small soldered wires should go through the entire shaft and out of the lower encasing ( small drilled hole or maybe there's some other way of taking the wires out of the encasing ).I think there is a way to do this with quality, even as a DIY project. Time and some design effort is needed though. If anyone can find smaller dome switches, please provide links, etc.EDIT:Theese are way smaller: https://es.aliexpress.com/item/50pcs-lot-metal-dome-3-7-3-7-0-35mm-thin-film-touch-switch-4-feet/32807076345.html?spm=2114.43010208.4.80.C7X0do I don't know about the feedback though.Also, and I think it would be better, by printing the whole piece with a 3D printer and just using the dome part:and encasing it in a small/shallow hole and putting our own mini PCB or two metal contacts under theese domes, we could reduce the size and make robust clickable shaft replacements with a pass through wiring and good feedback, etc.What do you think ?
