I decided to document the "WinDIYingThing" in a separate project log. I think that way you can keep a better overview of the respective projects. :)

When building the nerd discerator I came across an annoying problem relatively quickly: winding the coils by hand is very time-consuming. Because not only the number of windings must be correct. The positions of the individual windings should also be as uniform and parallel as possible on the 3D printed coil core.

After I tried this (admittedly only once), it quickly became clear to me that it would be faster, easier and of higher quality if you let a machine do this for you.

This is how the idea (and later the implementation: see photos) of "WinDIYingThing" came about (yes, maybe I use the "DIY" tag too often: D).

Thanks to this small machine, I can now adjust how many windings are wound around the coil core. If you specify the diameter of the coil wire, the position of the wire guide must be calculated automatically. The principle can best be seen in the video below. :)
