howdy. saw this thread and was hoping that this would work for my application.
what i need is a IR break-beam circuit that closes a switch when the beam is broken. the breech of the gun(multistage coil gun) will be empty most of the time. in a multistage coil gun, the first stage is triggered by the operator, and the 2nd, 3rd, (and so on) stages are triggered by this break-beam circuit. as the projectile travels down the barrel, accelerated by the first stage, it breaks the beam. i need the break beam circuit to close a switch while the beam is broken, and open the switch again when the beam is restablished. if this break-beam circuit is not an energy-hog and will work well, then that'll be just fine, i'll buy and build. however is there is something better for my application, please tell me how. FYI, the switch requires little to no current, just a completed circuit.
i'm kind of a beginner to circuits so please explain in everyday language. i can build basic circuits and wire LED's and whatnot, but im not quite fluent in building a 555 timer, so that should give you an idea of where im at.
