When trying new wire or different coiling diameters by changing wicks it can be a hit or miss affair trying to work out how many wraps will provide the desired resistance, especially if you are new to coiling.
We would like to present a calculator for your use that takes all of the hardwork/guesswork out of the process.
Simply enter in you wire and wick details then the resistance you'd like to achieve and the calculator will do the rest - telling you how many wraps to make.
Clearly this will depend on how tightly you wrap your coils but it beats sticking a wet finger in the air. The calculator works for different sizes, types and even mixed wires.
