How long can you keep ferric chloride?

[Lee_ranaldo]

Chemicals are a real environmental problem (not like global warming) and making cocktails only makes it worse. I'd guess you are not worried about signal to ground plane so look at the real alternatives. First point to point looks good if cleanly laid out. There is also a tool that drills a hole into copper clad and makes a little round solder point at the same time. You could also use a universal breadboard.

a bit of topic but as far as i know

global warming is just a scam!.. as far as the temp goes UP it also goes down. just remember those hackers that got into some famous university info about global warming and they were hiding this fact :P
