Hi, I want to build this circuit: **broken link removed** and I'm having a problem with L1. It says,
"The inductor L1 is 3 turns of .5 mm wire on a 5 mm ferrite core." and I'm not sure what that means. "5 mm ferrite core" is somewhat broad, as there are many different types of ferrite cores, as I understand. ".5 mm wire"? Since when did they start measuring wire in mms? What happened to AWG? (Though, AWG stands for American Wire Gauge, and this isn't an American site... as I just now saw...) Is this supposed to be enamel wire? I'm confused... and I don't know where to find either of those things, the ferrite core or the wire. Can someone please help me here? Thank you.

P.S. I just looked up a chart, while typing this message, that tells you how many mms and inches AWGs size 50 to 10 are, and according to that, .5mm wire is about 24AWG, right?
