Lately I've been seeing a lot of posts and videos on various social media and YouTube of people building crazy coils. Like twisting wire then wrapping it with more wire or twisting wire and twisting it again, or braiding all sorts ok wires and then wrapping more wire around them. There are all sorts of crazy names the best one I saw was "Alien wire" lol. So what gives? Are there any actual advantages of people spending crazy amounts of time making these coils or is it just to see who can wrap the prettiest wires together? If there's a noticeable advantage to these coils then maybe I'll take the time to replicate some builds but as of now I just don't know how I feel about them.
It's about getting more surface area out of the same mass of coil wire.
You can also use ribbon wire instead of round wire to improve the surface area ratio.
