I'm working on a metal detector project and have run into a problem. It's all built except one part - a variable inductor (Miller #6196A), .054 millihenry to .5 millihenry powdered iron core. That's all I know about it.
I need two, or I need to know what kind of core form and how many windings are needed to make an equivalent part. Or if there is an equivalent available somewhere. I have searched the internet thoroughly with no luck.
I'm a beginner at building electronic projects, so I don't really understand the inductance formulas I've found. Any help would be greatly appreciated. Thanks!
The project is from this website - http://www.geocities.com/Paris/Musee/3308/About/md_plans_ocr.pdf
