Homebrew PCBs

If you are a chemist with the ability to make it from scratch,
There is also http://www.postapplescientific.com/
You can probably find a distributor of elementals within driving range, thus
saving on shipping.

If you can find a recipe for a non cyanide, fluro, or formaldehyde... carbon
or graphite system. By all means - post it.
