You got me with those fractal curves just as I was riding on some scalar waves and I like those fractal antennae.
Yes, I only achieved a high school education and self-taught after that (however I did do my Dip Psych when I was about 35 - just for fun).
Thanks so much for those tips (Alibaba etc) I'll look into that...and I'm still tossing up between the biased Schottky Diode and a Germanium Diode (old habits die hard)...but getting spare components is a very good idea...and I liked that interchange between you and your lab partner.
Top of my 'gadget wishlist' is a structured light sensing camera. I could use the Microsoft Kinect for Windows, but it's not the same thing.
So, that defining moment? That moment when I was turned from 'scientist' into 'true believer (and scientist)?'
