Just built my first coil the other night....I have now gone and bought just about every kind of wire out there lol. I tend to go overboard sometimes. I am really excited about being able to build coils now! I have not attempted to fire any of the ones I have made yet. I do not know a lot about how many wraps to do and what ohms etc. So I won't fire any up until I have an understanding of how it all works. Any tips and advice would be greatly appreciated!
