Homebrew PCBs

The prices of the pumps in the spray etcher projects were $180, $77, and
$100.  They all appear to be water pumps but I'm not sure how the builders
knew they would work with etchent.  Todd, how much did your pump cost?

Jeff,

Look at

http://www.instructables.com/id/The-Etchinator-low-cost-spray-etcher/

The instructable also contains a link to Adam
Seychells more professional etcher (a member
here also)

There are also a few more ideas such as the
splash etcher someone oft mentions here (search
is your friend)

All of them are reasonable ideas. Most of them
would actually be cheaper than an electric
spray paint gun and NOT have corrosion problems.

Ferric Chloride does have its place BTW. Just
not for PCBs unless you don't do them very often.
