If you are interested in sharing your code and the
how-to, Mike had created
http://www.emdash.electricmotorcycles.net where he had
been working on creating a monitor and display for his
EM hence the emdash. Anyways, if you join that, there
is a "my uploads" section that should be able to be
shared. I believe the max file size can be 16Mb.
After uploading, it should be easy to copy a URL and
add it to an email. This portion of the site has had
little activity but is still interesting to brouse
through.
