Lol, I'm terrible at math but thankfully there's an app for that. I've learned more about batteries and electricity since I started vaping than I ever expected to know. The tinkering part and actually building with the wire came easily enough as I'm crafty and have worked with wire in jewelry/rosary making.You sound very similar to myself........... Hey, this forum can't have two weirdos! .... yeah I know what you mean about single coil building being a breeze compared to where you came from ...... I was involved in Electronics for most of my life, as a career, and so building coils and anything electronic never phases me in the least.... Well, that's not exactly true because working with Nickle coils can be a real b*tch lol .... But the Mathematics and the theory are nothing to me as I have done that stuff for years.
And there's *plenty* of weirdos up in this place. No wonder I feel right at home.
