Homebrew PCBs

Chris,

I suggested this a while back, and am still convinced
that Tarn-X is somehow involved in this, maybe just to
the extent that rubbing the board creates an
electrostatic charge which causes the ink to hold
rather than puddle.

The obvious thing is for Volkan to try making a board
without using Tarn-X and see what, if any, difference
occurs.

I don't think Tarn-X is available in the UK anyway.


Meanwhile, I think I will continue with the EDM
development until I see how this one pans out.
