Homebrew PCBs

Tinnit is available on Amazon of all places. They seem to be selling a lot
of hobbyist electronics stuff recently. $6.90 + $5.15 shipping. That's
enough to plate 200 square inches, if I recall correctly.

I've used it a couple times, works OK if you follow the instructions
carefully. The copper really has to be completely clean.

The powder lasts forever if you don't mix it up. I mixed up half of each
package and used it. About 13 years later, the solution didn't work, but I
mixed up a new batch from the remaining powder, and it worked fine.
