[dorkbotnyc-blabber] how to make a water pistol?

[Roy Pardi]

Hi -

I've come up dry in my circle of tech friends so I'm branching out...

I'm building a computer controlled drawing machine. I need for it to be
able to spray ink (watery, etc.) some distance - as would a water pistol or
one of those spray bottles that can be adjusted from a mist to a steady
stream. I need a steady stream - the finer, the better.

An air brush isn't going to do it and I have been haunting hardware type
stores looking for nozzles I might be able to use or some kind of tech that
can be adapted.

Anyone have any ideas? I want to be able to shoot short bursts - likely
using a simple solenoid valve - and I have a compressor - but I am stuck on
where to find parts for the actual spray apparatus.

thanks!
