I've been using an android app call "
vape tool pro" (there is a free version) for most my builds. There are some it doesn't support yet but for even some advanced builds you can get an idea of where you'll end up. I love it and works for 99% of what I do unless I do some staggered clapton double fused helix or whatever (not sure that's even real....vut could be haha) or like braided coil it doesn't support but most of the main stream stuff.
The flamethrower is evidence that someone, at some time said to themselves "I really want to set those people over there on fire, but I'm just not close enough to get the job done"
