Here is a fun DIY project, to create a 3D printed variable inductor.. Links to parts list are provided in my Youtube video, demonstrating how to build and test this nifty little device! Variable inductors are a great way to make resonant circuits and home made electronic oscillators.. and it is difficult to find these types of components any more!
