I somehow got it into my mind that the bus bars were all shorted
together, this is what I meant (and what you interpreted correctly
anyway):

The wiring to the chip could be a bit clearer. You left a lot out
from the schematic too, I started adding some of it.

I used box-style resistors bacause I haven't had to figure out the
best ways to do American zig-zag resistors myself - I'll leave that
for you to figure out, if zig-zags are preferred.

There is software specifically for drawing ASCII-art schematics. I
Can't remember the name, (might be more than one program, probably
for Windows or DOS). That might be handy if you're doing a lot of it.
