Could I have some help coming up with a circuit that turns it self off after three momentary button presses? Answered
Hi, I was wondering if I could have some help coming up with a circuit, Basically me and my friend are modding nerf guns and I thought it would be cool If I could find a way to make the rapid strike fire three darts then stop (or three round bursts XD)
Any how the part of the dart gun this in-tales seems to be the little arm that pushes darts into two rotating discs (this is one that uses fly wheels as opposed to a plunger) it works on a motor and gear that pushes it in and out, pushing the trigger activates this. (I thought it would be a solenoid and that the trigger would put out electricity in bursts, or are those called pulses? any way that's where all this using a momentary switch idea comes from)
So if anyone thinks that they can make a circuit using only the power from the trigger and lots of good timing a lesson would be much appreciated :D
My Idea seems unnecessarily complicated but it's all I could come up with :D ,Any way the idea for the momentary switch circuit would be put some form of proximity sensor switch near the arm (the one that pushes the dart into the fly wheels). Something like a magnet switch or IR thingy ( I forgot what there called I think magnetic reed switch and Infa red proximity sensor or detector?)
the idea after that was that each time the arm passed the sensor it would activate the sensor, using that and the trigger(if they were both needed to initiate the circuit then releasing the trigger would reset the circuit) the first and second shots would push the dart into the fly wheels and the third would also push a dart into the fly wheel and turn off the circuit(or turn on the circuit activating a spdt relay and switching the link to the motor off)
So far I've come up with some ideas using relays but just pressing the button once activated the whole circuit, I've also though of using a capacitor but I don't really know how to use them, if they work by holding X charge that can be filled by pressing a momentary button, that is hooked up to Y amount of power (possibly through a resistor), Z amount of times fills the capacitor stopping the circuit that would work, though I would have to find a way to discharge it...
Thanks for any help if I get any XD , and if posting my current not working circuit designs would help I'll do that, just have to figure out how to draw a circuit...
