Homebrew PCBs

Links some people may feel are worth viewing for ideas or inspiration re: various approaches, I found them interesting, it seems all of the parts to make this happen are out there;

Copper is an amazing conductor of heat. Bringing the copper-touching toner to a fusible temperature without the laser-facing top layer vapourising would be very difficult.

That said, try it and report back! If it does work, it could be very useful.  I would start with a warmed PC board (close to but below fusing temperature) to minimise the loss.

And good luck.
Donald.
