: hmm, well, question 1: : is the 3/4" elect. sprinkler valve worth dealing with? Both seem to work but for a cannon in a tank I would lean towards the 1" just so it would be a little beefier a the 1" fittings. Might get a little extra flow. Being debated as we speak on this forum. : is it better to go 1" ? eventhough internals are the same? : is there such a thing as a psi-actuated switch that can complete a circuit? (i guess it would be called a pressure switch?) like, once the pressure agaunst the switch reaches a certain point, it completes the circuit? but not pushbutton, i mean accurate to a certain psi.... Yes there is but I don't have a good understanding of how you are planning to use it. A substitute for a pressure regulator? To turn off the air supply with a electrical valve? Probably not consistent relative to a pressure regulator. Rules generally require a regulator.. A sensor to light up a LED when you are recharged and ready to fire? Or to prevent firing until recharged? It should recharge long before you get the next round loaded and locked or are you working on a semi auto cannon.....? Copy and Past this to find more pressure sensors than you wanted: http://sensors-transducers.globalspec.com/ProductFinder/Sensors_Transducers_Detectors/Pressure_Sensing : and the last one... can i ask how l.e.d.'s work, or should i just go to howstuffworks.com? i think ill go there anyway, but its nice to get stuff in english. i went through a class on diodes in the army a couple months ago, but the instructor glazed over leds. also, how do they not act as a short in the circuit? seems as though theyd steal most of the current, as their resistance is generally less than that of the connection that they display is present ( i just had a thought... are they inline with the main wire? i for some reason assumed a parallel circuit). anyway, um, i guess thats it for now... : oh, also, what width of plywood do you use for sides, and also what do you use for.. and how thick is your framing (goes to all ppl, id like to get lots of answers to these 3 esp!!) Generally, One side is hot, the other ground and they light up. Has to have the right voltage but draw minimal current so they don't act as a 'short'. : anyway, thanks for your time, hopefully see some guys onthe field sooner than 6 years, lol : -Peter My RPG is waiting.....
