I have an issue now... What do you do when those black carbon conductors begin to wear out do to years of usage, and continuous pressing? Well the likely solution would be to chuck the device away, and buy a new one! Wrong...
There are apparently conductive paints available, conductive pens, goos, stickers of some sort, and homemade foils you can use to supposedly restore the keys. Now from what I read some of these are gimmicks, and do not hold up to continuous usage, or don't work at all.
So I figured I'd create this thread since many of you have highly intelligent minds, and could potentially offer me the best solution to repair/renew black carbon conductors under rubber keypads. That will hold up to the pain of multiple presses, and massive usage. & no I don't want to cut the carbon conductors off a spare keyboard, or calculator and glue them on my faulty ones. As that could mess up timing in things such as a video game controller due to height issues.
If you know of a rock solid way that can withstand a beating like it stole something let me know! Links would be good, homemade advice, or whatever you can offer. I need a long lasting solution specifically for some old video game controllers I use on my pc that they do not sell anymore. The keys on the controllers have to withstand a pounding! I also have tv remotes I would like to renew that have buttons you have to press so hard just to get them to work, as well as other old video game console remotes [Nes, Snes, old stuff like that].
