Godwin, Daniel,

Thank you for your help.

I've been looking at Godwin's diagram for a while, and I think it's both 
tantalizingly close to my ability to make it, and yet just a little too far.

I think I understand how to organize Godwin's schematic in terms of 
which parts go where.

What I'm unclear about is how I construct the board on which they go. 
The ones I saw in Akihabara all had copper on one side and holes through 
it. I don't get how those are used without connecting everything to 
everything and shorting out the system.

I have a vague notion that chemical etching is used, but that starts to 
get into a level of electronics design that is above me, not least 
because I only have a soldering gun.

So I guess I'm asking another basic question... what kind of mounting 
surface should I look for that gives me the best balance between 
versatility and ease of construction. Ultimately I want to cut it into 
some kind of circle.
