[TCML] Mini Solid state coil?

[Eric Anderson]

Hi everyone,

I just joined the list and am so far overwhelmed with the activity so  
far.  Nice to see so many people enjoying themselves doing this!

So, I'd like to build a small (secondary around 2" or so) solid state  
coil, that either runs off batteries or a power brick of some kind.  I  
have been looking at this site a bit:

http://www.extremeelectronics.co.uk/coils/

I see they have a couple of small coils like what I want to build. I  
see some circuit drawings on there, and some vague details.  Has  
anyone built one of these tiny coils, and are there any better  
descriptions on how to build one?  This will be my first real coil, so  
you should expect a lot of questions coming up. :)

Thanks!
Eric
