There are drip atomizers, and there are
rda's. Those are Rebuildable Dripping Atomizers. A normal drip atomizer you don't need to mess with. They're disposable. A
rda requires you to build the coil with a wick. You can use many things for a wick, like hemp, cotton, silica, stainless steel mesh(SS), and many others. You can customize the resistance to whatever you want it to be, with some knowledge and/or experience. There are also RBA's, which are ReBuildable Atomizers. Those are genesis style atomizers. You can buy a RBA, RDA, or an atomizer capable of RDA and RBA. I have an AGI, which allows that capability.
You'll need a wicking material, kanthal wire..the gauge you get will be around the resistance you're aiming for. Get a higher gauge wire to start out with first, before you go on to mess with lower gauges. With wires, a higher gauge is a thinner wire.
Get a multimeter. You may want to get a butane torch and maybe even a good pair of scissors and a magnetic tray to catch the tiny screws when you're tinkering with it.
What kind of battery do you have?
