clarify a few things for me then,
solenoid switches the co2 off automatically when desired?
reg regulates the flow
I dont need a solenoid if I am there to switch it off manually, if im not home I wont run it at all, simple (cheap more like it:P)
reg, if I were to make my own method of getting the co2 out of the bottle at the desired pressure, then control that further with a needle valve from the model shop, would I acually need a reg and gauge? How dangerous is pressurised co2? Ive made a bracket and using sodastream machine parts can get the gas out at between 1 and 2 bps, with a needle valve id have futher control. Im just not sure how safe is it? I think if they can be sold as bench top units it cant be too bad.
