Can you stable out a 12v dc pulse?

Hey guys. I made myself a pulse circuit but my power supply failed.
Now I need a way to use a 12v magneto as a power supply.
But a magneto puts out pulses. Can I put a capacitor or a diode there to make it a steady stream of dc current?


This is for my go kart 5hp briggs. for turn signal and brake light

Are your turn signals tungsten lamps or LEDs? Is there any reason pulses won't work? Yes you can use a diode and capacitor very effectively.

edit: id like to still use Leds and my timer circuit to get the blinker speed correct and use the magneto as the power scource

look at the battery charger coil on any electric start lawnmower engine.

one of those plus a bridge rectifier and huge capacitor will do what you want. 1950's British motorcycle guys used this technique to avoid having a battery.


look up how a magneto works....

For what purpose was this magneto, originally? What information does it provide on the plate?
