Re: BTC30 KIT lets help this guy build this thing.

I had the kit for about a week but I did not do anything with it 
because the directions confused me.  And then the teacher made me 
bring it back to school because he does not know if the school 
Originally paid for it or if the previous teacher bought it 
himself.  Apparently I can't have it if the school bought it and I 
might not even be allowed to build it without teacher supervision 
because if I get hurt I could sue the school and they don't want that. GRRRRRR
The school is slow at deciding anything but I am optimistic because 
the school will only buy stuff from certain companies and thankfully 
information unlimited is not one of them so there is a good chance 
that it was bought by the teacher and not the school. But the next 
meeting that the people are having is after Christmas.(yet another GRRRR)
I can try and get pictures and a list of every thing it comes with.
I will have to borrow a digital camera or I could just wait until 
Christmas when I will be getting one(yay).

There is a list of stuff on the plans but I don't know if the kit has 
all of it in it.
If anyone want the plans I could scan them and put it on 
photobucket.  How does photobucket thing work?

The instructions say that the transformer it comes with 6000v and 
23ma I don't know it that is the actual value or not.
I would buy a bigger one if there was a neon sign shop near where I 
live, and I would buy one from ebay except my parents won't let me 
for a while because not too long ago I spent $150 on a cool element 
collection.(The Everest Collection I highly recommend it if you are 
in to that stuff)

Same for the capacitors which is why I was wanting to make one and I 
already have some metal plates and I am guessing that some mineral 
oil and glass or plastic or something for a dielectric can't cost 
that much and could be easily replaced.
