Saw this a while ago:
Got me to thinking about doing some paintball related hacks, seeing as how I have a few spare arduinos and some hardware lying around.
I've been trying to conceptualize an autonomous RC drone paintball gun... I'm thinking I'd have to get ultra lightweight internals (thinking from a mini), and try to run a 12 gram CO2 as a replacement for a HPA tank.
Anyone have any fun arduino paintball projects they've been thinking about/are working on?
