Re: [Xylo-SDR] Cyclone II board
I print mine with a HP 2100 LJ set at 1200DPI on Epson Glossy Photo
paper, a GDC H200 Laminator to transfer the image, and use Ammonium
Persulphate to etch with, I like the fact that I can check and see the
state of the etching a lot better. I use a plastic tank that has a
sealable lid, and I use an aquarium heater to keep the temperature nice
and warm. Real amateur stuff here but it works well. I can get ferric
chloride from work for free, I asked and they don't mind an occasional
gallon or two, they use it along with a bunch of other things in water
treatment of way more toxic waste at the plating dept.

For simple home-made boards I
use Pulsonix to print a transparency on JetStar film in an inkjet printer
and use it with positive resist coated material, exposing to UV,
developing in sodium hydroxide solution, and etching in ferric chloride.
More complicated boards I get made for me from the Gerber output files.
It isn't expensive, even for four-layer boards.
