Homebrew PCBs

Here is a crazy idea that might just work:

A first requirement is being able to cut out a PCB the to look just like a
CD.  It needs to be accurate and typically a lathe would be used.  Apply a
layer of paint or other protective coating over the copper.

 

Pop it into a CD burner that has the Light Scribe or whatever it is called
feature to mark CDs.  Take the layout and convert it to a JPG and use the
marking software to place it on the CD.  Several small SMT PCBs will fit on
a CD.  "Write" the picture to the "CD" and hopefully it will vaporize the
paint.  Afterwards etch the boards as usual.  

If the power is controllable, it might also be used to expose a photoresist
as an alternative.
