Homebrew PCBs

You mean the acetone simply made the toner go from the paper to the copper?
Hmm interesting... do you have a link to that webpage? I'd like to see
that...

I read something on a web page about transfering the
image with a solvent pen. I tried it with acetone and
the image transfered very nicely. But it was not hard.
It needs heat to harden it.

I put the paper back on and applied the heat. The
image went back to the paper. I am thinking about
trying it with a fresh piece of TT paper. Just to see
if it may work.
