Ferric chloride gone into liquid

I've never tried it, but you can mechanically mill the copper rather than etch it. A CNC mill can automate the process. BusyBee's little board in the last post looks like a crude version of of milling. BusyBee also reminded me that I too used paint (car touch-up) as a resist.

I grew to really dislike standard Veroboard. Give me plain matrix board any day. Sometimes I've used "colander" board which is like matrix board but with a ground plane. I've occasionally used boards designed for DIL chips which have power buses. I've still got the wiring pens that use very thin solderable enamelled wire. haven't used them in years.
