[sdiy] Laser etching powder coated aluminum

[Dave Leith]

I've been getting my panels laser etched on pre-coated materials. Only
gotcha for me anyway is that the pre-coated material is thin and I
need to back it with steel panel but it's reasonable price and looks
great.

Also thanks must also go to Cary who helped me with some of the older
circuitry. It sounds great!
