Small Scale Scuba Gear within $100? Answered
I had an idea for a good instructable. I'm trying to plan out on paper a neat breathing apparatus for a hundred dollars. Constraints are that it has to fit on the face, can be carried anywhere, and should at least provide one minute of oxygen. As a plus, why not add a pump so you can replenish the air supply when its running low.
The way i might build this, ultimately, shouldn't be too hard. But what is being difficult is what to use to hold the air supply. would an air tank from an airsoft gun be any good? or would i have to use something different to contain the pressure? Any input would be greatly appreciated!
