    As a supervisor piece, that would wake up the main computer is, IMHO, a great idea. I hope to use an Arduino Nano (can be tucked away just about anywhere) and try to set it up for some functions, and perhaps because of threads like this, make it a supervisory circuit of sort that could also trigger the remote starter to fire up if necessary. I just need to dig into the remote box to figure out what on-board trace would do that, or use a spare remote. Hmmmm.....

    I love these forums.

    I'm not convinced you need built-in units for passengers these days. Especially given there are tablets and smartphones with more than enough capabilities. Not to mention, if you have the igepv2 serve up a upnp share, all the other devices can access it. It's not like the passengers have to have their eyes glued to the road. The passenger interface needs to be optimized just like a handset/tablet would be. And in that scenario, why reinvent the wheel?

    It really all depends. I know tablets are now pretty much as powerful (Motorola XOOM), with dual core processors. Now the thing is all tablets would not be connected to each other, unless you go the route trip is talking about, but that sounds complicated.

    I am not even going to try to keep my multi zone system on. Its set to hibernate. I did this because i dont feel that everyone will be using it right away. They will be more focused on the main system and by the time they switch over, the system will be fully booted. Now the main system I would love to have on 24/7 via sleep. Problem is, its a monster! How I did get around this is add a second battery to the mix. If you buy a good deep cell then it should be able to run via hybrid sleep. If the power get to low then it simply hibernates.

    IDK, it shouldn't be that hard. Throw a wifi AP in there (or in my case a little mifi AP). The rest is just software. Apparently windows 7 already exposes a upnp share. On Linux, it's just an apt-get away. I've been working for years on software that will bridge the gap and extend the vehicle to your smartphone tablet. It's a real possibility and not as complex as you may think.

    I just ranted a huge rant on the meego-ivi mailing list about this. Built-in hardware for multi-zone is much more complicated. Unless they are separate units you have to worry about audio routing and there is some setup of the zones to make them work right (associate input devices to each zone, etc). Separate devices solves this complexity... and if it is separate hardware, there's no reason why you can't have 2-3 igep boards embedded in your headrest if you don't like tablets.

    Its not that complicated hardware wise. Its software wise that it all becomes an issue. Mine has six zones. Onboard audio and 5 usb soundcards. Then a ATI PCI card with 2 video ports (VGA/DVI). Then I have 4 USB to VGA cards. Its all easy to get the touch screens paired to the extended screens. The CF 3.5 is used to map the soundcard to the display. It all works fairly well. Only issue I have noticed is that when I do a cold boot, the USB to VGA adapters are not recognized with the latest drivers. Since I hibernate its not an issue. I rolled back to the original CD drivers and it seems that its fixed the cold boot issue. I tired to go the separate hardware route but with 6 PC units. It was even more complex and in my opinion not cheap. Once I went the single system with emulated zones, it was much better. One PC to do it all.

    Just an update... It appears the major hold-up on this project is the touchscreen. It appears that egalax is completely broken in linux as it has been for the past year. While some egalax touchscreens work (ie, the capacitive variety found on tablets like the exopc/weetab), the ones we usually sport xenarc/lilliput are completely useless.

    I'm actually kinda irritated about the current state of affairs in available touchscreens for our hobby. The current available touchscreens are essentially the same crap we've been buying for the last 5 years. The prices really haven't changed all that much during this time but the available technology certainly has. Now we have capacitive multi-touch (even resistive muti-touch) screens, but none from our friends at xenarc/lilliput. We have AMOLED, high density displays... but not from our friends at xenarc/lilliput. We have super this lcds for tv's and computers. Why does my xenarc have to be 3 times as thick as my tablet? Does that seem right to you?

    So to solve this issue, I will end up purchasing the igepv2 expansion board and the 7" seiko lcd touchscreen. The expansion board is about the dimensions of the xenarc controller board I'm currently using, yet does a thousand more things. Does that seem right to you? I'll have hardware video inputs and CAN with this expansion board as well. The price combined isn't much more than some of the more expensive xenarc/lilliputs and I'm getting much more out of the hardware.

    As soon as the expansion boards become available again, I'm throwing down the bucks to make it work. I'm somewhat tired of talking and talking about this stuff and not being able to actually put it in my car. Wish me luck!

    You make some very good points. I'm looking to replace my resisting touchscreen on my Lilliput with a multitouch capacitive interface. If the screen ever dies; I'll get a better technology screen and smaller board. You mention AMOLED and that's exactly what my phone has. Why does my phone's screen have to be years ahead of my car's screen? Good luck on your quest for newer tech. Keep us posted.

    Hello everybody hello tripzero

    I read all the topic but forgive me if I repeat something which has already been said:

    I'm thinking of shrinking my carputer project these days (still on Epia M10k)

    I was reading some articles about netbooks etc. and came back to alwaysinnovating solutions, then this: https://www.alwaysinnovating.com/beagleboard/ their maybe-next-motherbord-model

    The board seems interesting for carputers, Pandaboard a little more (but I didn't remind why, now)

    And then I read this http://www.openbricks.org/the-5mn-overview/ did you know ? It seems perfect to me :]

    Beagle and Pandaboards are certified to work with this !

    I'm interested in it but stuck with the software, meego IVI seems to need a little more work (for the appearance too) and I didn't find something else complete. (My software project is still on paper because I don't have the skills)

    Did someone try something ?
    Or have a linux carputer software to advise ?

    Thanks

    IGEPv2 RC and Lilliput

    I have the IGEPv2 RC and the TFT Lilliput screen 569GL, but it seems that they not work properly together, at least with the bootargs that I currently have:

    setenv bootargs 'mem=430M console=tty0 console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait ro earlyprintk fixrtc nocompcache vram=32M omapfb.vram=0:8M,1:16M,2:8M omapfb.mode=dvi:1280x720MR-16@60'

    Can any one, who has sucessfully tested both systems, suggest a different setting

    Regards,

    Leo

    I think lilliputs default to 800x480...

    I think with the omapfb you'll only be able to pump out 800x600 to a lilliput successfully
