Re: [TCML] PC boards
that was the way i did it bart for along time.
but if anybody gets in a jam and needs a pc board done contact me off list as i have equipment to do the pcb.
just for prototyping no thru holes but i have ferric chloride laser printer and tooling for the holes.
works just fine when prototyping a layout.

Something like a simple driver board is fine for etching. It's certainly
the lowest cost solution for a 1 off board. For drivers, it's typically
a bus voltage, output from the drivers, and the gate for the driver. One
recommendation I would make is to simply etch out the areas between
traces (don't etch out huge areas for a specific trace width). The areas
between each net is simply an etched-out trace to disconnect each net.
This really reduces the copper that needs to be removed and speeds up
Back when I did etch boards (I use board houses these days), I simply
covered the copper clad with good masking tape (wide tape), pencil in
the traces between nets, used a razor blade to cut along the lines,
removed the tape, and soaked the board in etching solution. Worked great
and is simple to do.
