Secondary Coil rough approximations from both frequency swept modes of the coil. Secondary grounded gave me a low frequency resonance with 519pF, and the later high frequency dip at 800K+ is resonant with 72.6uH. It doesn't dip here in the simulation so I need to go back and do some real calculations insted of guessing. First dip at 330K with the 8.5pF series resonant system. This is going to be quite a bit of work.

Myke what the heck is that, is the green thing a 12" ruler?
The scale says 6". Still big.
Sulaiman: a lot of my junk is much older than me. I wouldn't be surprised if most if it were. I should post a picture of my early op amps sometime. They're bigger than a matchbox.

Finally, after making several comments in this topic, I finally have something to post. Afraid it's not a photo though.
I have tried drawing in the past, but it was more cartoony, and after a while, it got put on hold. But I found my art folder last week, and inspired, got out some books, read them, then picked up my pencils again.
And I ended up with this after a practise attempt (click for full size version):
I did draw this from a source - the cover of the UCAS magazine that appeared in my house recently (again, full size on click):
Not a perfect copy, but pretty good nonetheless. Quite fun to do as well. I need to do more of this drawing lark.
