All you builders out there: I really want to get into building, and I've been watching a lot of youtube videos and I have a question. Is it really that deceptively easy? I'm looking at beginner single and duel coil setups and it seems oddly easy. I understand Ohm's law and all that but it just seems not that hard. I'm confused that I might not be getting the full thing. What sites, etc did you use to learn?
