Hello I have never used a forum before but I didn’t know what else I could do. Last year I started a project about making a little pocket taser. I followed YouTube tutorials and bought numerous boost converters and all of them worked for a few hours and then stopped. I tried to research why but I could find nothing. I was looking through my old stuff today and found all of my supplies and started researching again and I found out my problem was I was using 9 volt batteries. I don’t know how to still use my recharging 9 volt batteries but make a taser too. I’ve been reading about the converters that make it less and more power and I’m very confused how I would use it to make a taser. Help? ):
