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.

What about heatsink thermal paste?

That's not conductive, that doesn't conduct electricity. At least not the kind I have around.

I know at least one kind that had a high degree of aluminium in it. But you also have cheaper kinds that dont have that.

You do make a good point, which I was already aware of though.

But you also just reminded me that I bought some new heatsink compound about 5 years ago and put it up somewhere in one of my parts bins.

I actually haven't tested the conductivity/resistance of the new compound yet, but whenever I find it, that's probably going to be the first thing I check.
