The trick is to design your PC board to scale with some computer system that can output to a laser printer. A MAC or possibly a PC clone with graphics should be okay. Then you take the output and run it through the thermal machine. My friend typically uses two of these and stacks them to block out as much light as possible. Of course, the trick in all this is to make sure you get the scale exactly right and then to get the transparency dark enough. The results that I have seen are impressive for such a kluge.
