srosefx Posted August 12, 2009 Report Share Posted August 12, 2009 Hello this is my first post so please be gentle.Im looking to build a multivibrator circuit that pulses a light at 0.08sec intervals 3 times, at which point i want the light to stop pulsing untill the button is pushed again essentially reset the circuit.Im figuring that i could use a pulse counter to detect the fast pulses and on the 3rd pulse turn off the multivibrator circuit untill the switch on the vibrator circuit is pushed again.Basically im trying to flash super bright leds in a muzzle flash simulator for a theatrical effect. i want to use a selector switch (3 settings) semi/3 shot burst/full auto the semi will just be the switch hard wired to the led, pull trigger and led flashes, the selector switch on 3 shot burst is the tricky bit!! and the full auto i have figured out.the 0.08 sec is quite important to get right between flashes and the "3 shot burst" is also just as important.Is there a way to make a pulse circuit that i can get each pulse .08 sec apart? could i use a 555 with a small resistor and cap??any ideas??im new to electronics, i understand the basics and i know what components do etc thanks simon Quote Link to comment Share on other sites More sharing options...
