Re: Introduction

Hi Jeff,
I saw your intro to the opendiag yahoo group from two years ago and
noticed that we have a common goal to install a Linux PC in our cars
for music and diagnostics collection.

I've already got OBD2 from Alex Pepper and probably won't bother with
a Linux version of OBD2 soon but I was wondering if you had anything
to share about the car PC project?

I'm particulary interested in mounting, switching power, shielding
and temperature control. I expect to use the 144VDC stage of my
Hybrid's power to feed my PC and to avoid having to drastically
change a standard power supply for 12VDC operation like some people
in the car MP3 groups have done.

I took the time to look at the group and your home page for updates
but didn't find any. (I did notice that you seem very angry about
the 'me too'/'help me' nature of newsgroups...)

I for one am glad that people like you take the time to share your
efforts and even though I probably won't be using your OBD2 work
soon, I thank you.
