<p>Dear lazyweb.  I'm planning to set up a small Raspberry Pi computer
in my car, connected to
<a href="http://www.dx.com/p/400a-4-0-tft-lcd-digital-monitor-for-vehicle-parking-reverse-camera-1440x272-12v-dc-57776">a
small screen</a> next to the rear mirror.  I plan to hook it up with a
GPS and a USB wifi card too.  The idea is to get my own
"<a href="http://en.wikipedia.org/wiki/Carputer">Carputer</a>".  But I
wonder if someone already created a good free software solution for
such car computer.</p>

<p>This is my current wish list for such system:</p>

<ul>

 <li>Work on Raspberry Pi.</li>

 <li>Show current speed limit based on location, and warn if going too
   fast (for example using color codes yellow and red on the screen,
   or make a sound).  This could be done either using either data from
   <a href="http://www.openstreetmap.org/">Openstreetmap</a> or OCR
   info gathered from a dashboard camera.</li>

 <li>Track automatic toll road passes and their cost, show total spent
   and make it possible to calculate toll costs for planned
   route.</li>

 <li>Collect GPX tracks for use with OpenStreetMap.</li>

 <li>Automatically detect and use any wireless connection to connect
   to home server.  Try IP over DNS
   (<a href="http://dev.kryo.se/iodine/">iodine</a>) or ICMP
   (<a href="http://code.gerade.org/hans/">Hans</a>) if direct
   connection do not work.</li>

 <li>Set up mesh network to talk to other cars with the same system,
   or some standard car mesh protocol.</li>

 <li>Warn when approaching speed cameras and speed camera ranges
   (speed calculated between two cameras).</li>

 <li>Suport dashboard/front facing camera to discover speed limits and
   run OCR to track registration number of passing cars.</li>

</ul>

<p>If you know of any free software car computer system supporting
some or all of these features, please let me know.</p>
