    This is ingenious!

    Awesome idea, have you done any complicated or involved projects with it we could maybe see a picture of? I would love to see what it's capabilities really are. But regardless, great work, and thanks for taking the time.

    What kind of paint do you use with the air-brush? Sorry if that's mentioned somewhere else, I didn't see it.

    People tend to use watered-down acrylic paint (so it's the roughly the consistency of ink). Actually they don't water it down (although you could, and I do in my cheap airbrush) - they use paint thinner. Any paint should do as long as it's thin enough.

    Never use paint thinner for acrylic, or other water-based, paints. Use only airbrush medium or water. There are also recipes for water-based thinners on the net if you want to whip up a batch.

    I've always used water, but I'd heard that there were acrylic thinners you can buy. Never bothered myself because water's worked fine

    Hey, since you made this airbrush, and basically inspired me to design my own. Could you take a look at my airbrush and tell me what you think?


    This airbrush is awesome great job on it. I have one question. What paint do you use?

    that would work. a steady stream of air. and get those sprayers that have the mist, off, and steam settings to control the amount of paint. to make it even better you could add a throttle to the aquarium pump to control how much air is going through

    you could just hook an old light dimmer switch up to the aquarium pump to regulate the amount of power it puts out. i would also like to put something in that makes it so that you dont need to turn it off all the time just to stop painting... maybe you could put a valve on the airhose that would let the air flow out when you were not holding the paint trigger...

    or you can just use a small plastice valve found at pet shops to regulate the air output. It would cost less and be less bulky, it can be built into the air brush. As for a trigger you can always use a air gun. A air gun could in turn eliminate the need for a valve because itself is one :)
