For single turn inductances and shorter coils, I encourage you\nto consult the fine work of the late Nagaoka who published tables and formulas\nfor his correction coefficient. This was not a concern for the scope of this\nsimple calculator as such inductances are not seen or desirable outside of\nantenna systems or above UHF frequencies. I may decide to revisit this should\nthe need arise.\n\nMost calculators found online need either length or turns count to generate a\nresult. As they are both mathematically related, this has been simplified to a\nsingle term in the form of turns spacing. Thus all that is required is target\ninductance, diameter, and the turns spacing value to derive both length and\nturns count. I have found this much easier when designing coils, especially\nspacewound coils.\n\nEventually the capability to output capacitance and self resonant frequency\nwould be ideal, however the available formulas do not appear to be accurate\nenough to produce a result that would allow one to design and build a component\nsuch as a trap with any kind of accuracy. Maybe it's asking a bit too much right\nnow. Taking it slow and careful with the incremental progress thus far is\nproducing some results albeit at such a glacial pace.\n\n## tankfreq\ntankfreq.c is another very simple program which will calculate LC tank circuit\nresonance frequency as might be expected. \n\n## elcut\nelcut.c is a very very simple calculator designed as an antenna tuning aid. It\nwill give the estimated length to remove from a wire in order to bring it to the\ndesired resonance frequency as entered. It is recommended never to remove the\nexact amount given but instead gradually and carefully reach the resonant\nlength. As in the oft repeated words of Guy Wireson (whom has died), \"You can\ntake more off but you can't put more back on.\" If you don't think that's funny\nat least consider it my gift to you as the only person who will ever read this.\n\n## cap\ncap.c is the capacitor complement to iloc. It calculates dimensions for\ncapacitors of several different shapes. Simply provide the K permittivity\nconstant for the dielectric material and various dimensions as they are called\nfor. Though the algorithm is extremely simple, even moreso than the other\ncalculators in this collection, it does speed up the process and make for less\ntime entering formulas into a calculator (and less chance for mistakes).\n\n### Command line options are:\n* -p = flat plate capacitor\n* -c = cylindrical capacitor\n* -? = list of command line options\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flightningstalker%2Finduct","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flightningstalker%2Finduct","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flightningstalker%2Finduct/lists"}
