You need to achieve more advanced level inthevaping electronic cigarette.and need to build your great and the own coil.Some questions are still there:- which wire type to take and what AWG?- how many rounds do I need to make for acertainresistance/Ohm?- what if I need to switch from AWG to metric or back?You can get these answers and more with the help of thissmallapp!Just select different type of wire and simulate your scenario-answer will be promptly shown. All you need to do after this -justfinish the coil assembling!After you are happy with your new coil, you can always trysomeother wire, resistance etcAlso, watch for new features coming shortly!This application takes calculation/mathematically drivenapproach- please make sure that no shortcuts occurred duringtheassembling,Using of Ohm meter device is up to you.Vaping, smoking etc is just up to you.
