1 Title: Free software car computer solution?

5 <p>Dear lazyweb. I'm planning to set up a small Raspberry Pi computer
6 in my car, connected to
7 <a href="http://www.dx.com/p/400a-4-0-tft-lcd-digital-monitor-for-vehicle-parking-reverse-camera-1440x272-12v-dc-57776">a
8 small screen</a> next to the rear mirror. I plan to hook it up with a
9 GPS and a USB wifi card too. The idea is to get my own
10 "<a href="http://en.wikipedia.org/wiki/Carputer">Carputer</a>". But I
11 wonder if someone already created a good free software solution for
12 such car computer.</p>
13
14 <p>This is my current wish list for such system:</p>
15
16 <ul>
17
18 <li>Work on Raspberry Pi.</li>
19
20 <li>Show current speed limit based on location, and warn if going too
21 fast (for example using color codes yellow and red on the screen,
22 or make a sound). This could be done either using either data from
23 <a href="http://www.openstreetmap.org/">Openstreetmap</a> or OCR
24 info gathered from a dashboard camera.</li>
25
26 <li>Track automatic toll road passes and their cost, show total spent
27 and make it possible to calculate toll costs for planned
28 route.</li>
29
30 <li>Collect GPX tracks for use with OpenStreetMap.</li>
31
32 <li>Automatically detect and use any wireless connection to connect
33 to home server. Try IP over DNS
34 (<a href="http://dev.kryo.se/iodine/">iodine</a>) or ICMP
35 (<a href="http://code.gerade.org/hans/">Hans</a>) if direct
36 connection do not work.</li>
37
38 <li>Set up mesh network to talk to other cars with the same system,
39 or some standard car mesh protocol.</li>
40
41 <li>Warn when approaching speed cameras and speed camera ranges
42 (speed calculated between two cameras).</li>
43
44 <li>Suport dashboard/front facing camera to discover speed limits and
45 run OCR to track registration number of passing cars.</li>
46
47 </ul>
48
49 <p>If you know of any free software car computer system supporting
50 some or all of these features, please let me know.</p>
