Homebrew PCBs

Believe Dip Trace can rescale, never needed to use it so I could not say if it would work well for this.  I prefer photo process myself, get much better and repeatable results with photo process than I ever did with Toner Transfer.  I know some seem to find the photo process too much trouble, Myself I fine getting good toner process to be more trouble.
