Homebrew PCBs

That's a great idea.  For small boards possilby a CD drive hack would do. Would take some code to convert the cartesian data to polar data.

One could possible mount several diodes on the radial lead screw to write multiple sections at once to speed up the process.

Another one I though of a while back was to use something like a DLP projector with a UV source. But that gets complex.
