3D Printed Variable Inductor

Ok, here is an interesting DIY electronics project. Variable inductors are great for making tunable resonant circuits, and tuneable oscillators.. In this video I us a 3D printed from, and some parts readily available online for for order, to create a 2-12mH inductor. I use my LRC meter, and hand held network analyzer to measure the inductance of this nifty little device! Links to the FREE stl file, to print your own inductor..as well as ferrite core.. and the other equipment I used are all below!
