As from subject, how can I post a schematic, what is the usual way?
Either post it to alt.binaries.schematics.electronics, preferrably
with the same subject as the related post here (or elsewhere),
or put it on some web space and provide an URL in your post.
I'd prefer the latter since a.b.s.e is accessible at only few news
servers, and most people need additional accounts to be able to
read these binary groups. Additionally, there often are a few days
delay before your schematic appears, which decays discussion somewhat...
Oh, there's a third way: if the schematics is small, post it
inside your message in ASCII form. You might look for Andy's
ASCII-Circuit (aacircuit) as a help.
