Super capacitors and getting same current burst out every time using boost converter?
I need to use a supercapacitor to power a circuit for short pulses evenly. So with the same current out every pulse. To do this, I thought to use a boost converter to get a constant current out every ...

Will this Arc Lighter Circuit Work?
I am attempting to build a really cool thing (at least I think).
The goal is to build an arc lighter that I can shake to charge (kinetic power).
It's a circuit that combines an arc lighter circuit ...
