The copper circle on the PCB is 25 mil :-)
The wire is more like 12-13 mil. It's about 32 gauge if you take it
from 22 gauge 7-strand spe

Wow! You are able to pass a wire larger than the hole? :-)
Now realistically, thin wire is often sufficient, unless you
have very large currents

That would be enammeled wire or "magnet wire". I can't find the page now,

In my pre-laserjet days I went to my local drug store. I would bring my
printout and transparency sheet and get photocopies made for 10 cents each. I

I never plate my vias. I use 13.5 mil holes and 25 mil diameter
copper, very tiny. I de-strand some 22 gauge speaker wire to get tons
of through-board jumper wires and just solder them from one side to
the other.

For two layer boards, plating the holes is the hardest part. You can
get through-hole rivets, but I've never tried them. One trick is to
make a two layer board, but use jumpers to connect the two sides. You
just need to make extra large vias with solder pads on each side and
then stick a short s
Er, how are you planning on making *any* board at home, without a

For two layer, just do whatever you do for one layer, but on both
sides. Pre-drill a couple of holes to help you line up the two sides.

I do 2 and 4 layers at home, no reason why you can't do a double sided
board. Are you using sockets for all the ICs, or soldering them
directly?

I've designed a circuit that I'm planning to home-fab, and as such, I've
had to design my board using only a single layer. After about a week or
so of puzzling, I've managed to route it. Unfortunately, it looks like
