What's the makeup of the commercial epoxy? I remember reading in your earlier post that it has the silver flake, hence its conductivity. Theoretically, would a silicone adhesive be of any use, in that it's semiconductive and then add in the copper?

It's all very Mr. Wizard for me to read your posts, in that I don't actually have any experience but find it fascinating.

I think it's silicon that's a semiconductor. Silicone is generally not, IIRC.

Another thing that comes to mind would be to make a thin patch of a material that you can easily solder to, with a short length of wire trailing off of it. Then put it in place and use the epoxy over the edges to keep it on. Could be bulgy, though.

Glad you're enjoying the posts:)

In general, you've got a good idea, a more conductive sticky material to mix with the metal powder would be help the overall conductivity.

Specifically, the previous commenter is right. Silicon is a shiny, hard, brittle element, an electrical semiconductor used to make solar cells, transistors, etc. Silicone is a soft, rubbery plastic, an electrical insulator, named because it contains silicon atoms instead of carbon.

If you want to try some science/engineering projects, I'd recommend

They have a whole bunch of cool experiments to build.
