Making your own inductors at home is such a satisfying project. Theres something magical about winding wire around ferrite and actually understanding the physics behind why it works. Did you measure the inductance values against your calculations? I always find the real world results differ a bit from theory.
Could not agree more! And yes, though due to the lack of specifications available for the ferrite rods I purchased, it ended up being more of a calculation of their permeability based on the measured inductance. I'll have another post soon that shows measuring the resonance frequency of these inductors with various types of capacitors, which is a fun exercise in parasitic capacitance and inductance.
