Recommendations for safe pneumatics? Answered
I'm looking for a pneumatic setup for an air tank and a blow gun that is safe enough to use around school kids. I want to provide pneumatic feedback to give the sensation that they were hit by a small gust of wind. Safety is the foremost concern on this. What size tank, psi, and regulator should I use? Also can this small 'gust of wind' be controlled from a USB port?
