Re: Making Keyboard Membranes

Maybe a rubberized conductive paint is available to make small batches of membranes halves with conductive traces using stencil.

The nickel paint I just used is too brittle.

Re: Making Keyboard Membranes

I was thinking he was asking about the "rubber membranes". Is that what they are being called? As opposed to the "circuit membranes". If he means rubber keys, I am going to taken resin and silicone to make a mold and production of new ones. Very difficult... because of tiny spaces... Maybe injection...

Re: Making Keyboard Membranes

I am working on this without using mass production molds... the reason was to make membranes that had no keyboard labels that could be customized.

Otherwise use Retroradionics for replacement membranes.
