For one, before you start building alot will depend on what mod you're using.
Generally for a new builder I tend to err on the side of caution and tell them to start with a 1-1.5 ohm build using 28g kanthal.
You will need :
Toenail clippers, tweezers and an ohm meter. If no ohm meter a regulated mod with an ohm readout.
Only certain mods can utilize ni200 since it has very low resistivity. Its used for temp control mods. Furthermore, some mods can't fire below a 1 or 1.2 ohm load.
For the sake of argument an istick 20 won't fire below 1 ohm; but, an istick 30 will fire to a 0.5ohm.
Again for most new builders I tell them to go with a single coil build at 7 wraps of 28 g wire around a 2mm drill bit. It's a fairly basic build, easy to learn and just about any mod will fire it.
Ideally though; the best thing to do is if you have a GOOD b&m go over there and ask them to show you how to do a 1ohm build.
Or check you tube- alot can be learned from some of the you tubers.
Congrats on the next step!!
