Does anyone have any advice on how to make homemade conductive paint to fix a cracked carbon trace in a game controller? (lemmy.world)

It's the trace going towards the mode button, so I'm pretty sure resistance won't exactly be critical over a ~3mm gap, as long as it recognizes when the plunger button is pressed down.

Graphite pencil?

[โ€“] over_clox@lemmy.world 1 points 3 days ago

Yeah, that was the first thing I tried, but the gap at the cracked spot itself has a bit of a ridge to it and I can't get enough of the graphite to properly fill in the gap without the controller basically ending up with a bunch of loose graphite powder.

And it definitely ain't a good idea to try to realign the crack, I've already super glued that in place, soldered all the broken copper traces, and got everything else working.

It will need to be some sort of paint that can bridge the gap and make contact.
