    Lightbulb Holden WL Caprice - Build #2 - Pending

    Hello again people

    It has been awhile since i was last here and am creating this post so i can start to get myself back on track.. Posting here always gave me some motivation to keep the project going... Well now its time to change the hardware.

    Firstly... My old thread: Holden WL / VZ Caprice GENIII LS1 - Slow Build Follow - Some Tech Info
    - Using a Mini-ITX setup with a generic touchscreen and so on... read if you are bored.

    So now on with the Raspberry Pi B model

    Being i have yet to receive my Pi but it should be here today if i am lucky, i am very curious to see what people have thought about these and if they have had any issues with them apart from being limited with speed/input/output and the obvious linux requirements. (Would prefer windows but willing to learn linux to speed things up)

    Also, has anyone here had a chance to play with this PICAN - Canbus - are they limited as am looking to decode/reverse engineer my vehicles stream.

    And also what about the gertboard?? anything better than this around ?

    In the near future i will be order This Screen and by the looks of it, it should be a direct fit... Past the days of making a custom screen fabrication.


    So why the Pi vs other install types...

    -ITX boards: Seem to take up to much space when you include power supplies and have also have plenty of failures with them or the power supplies (Yes i know my electronics, but stuff more like bios failures and so on) not to mention the price each time.

    -Tablets: While a lot of people swear by these, i personally find them limited and am a hands on person. I want to be able to hard wire everything and keep the installation hidden as much as possible while developing custom software to match. For the depth of integration i have done in the past, These will not cut it for me.. Further more Australia has some of the worst laws relating to devices like tablets/phones in vehicles... So these needs to feel as OEM as possible.

    -Mobiles: Read above relating to tablets, also if my mobile gets dropped or breaks.. I dont want to wait until i can replace it vs buying a another Pi at the local shop and having it fixed within 5 minutes

    -Arduinos: While i enjoyed using these, they also felt very limited and did not allow great speed or gfx. BUT i will most likely be using an Arduino still for the hardware interface level side of things.

    -Headunits: Limited regarding software and hardware interfacing...

    Anyone played around with the GM LAN on a holden?
    - I would love to be able to update my DIC live and know this is possible, But lost interest and want to get back to this. Also aware of all of the sites relating to GM Lan Hacking... But need to get my new carputer up and running before getting back to this as it is also one of my main goals.

    -----------IDEAL FEATURES--------
    1: Low power use - Will at some stage have a Aux battery
    2: Touchscreen - This is worrying for linux but know it will be done
    3: Hidden/Flush - Thats why going for OEM
    4: GPS - i hope my old receive has a linux driver or more costs
    5: CanBus / GMLan - As above, curious if the PiCAN will do as i need
    6: Audio/Video - Fairly simple of course (Miss my old 5.1 surround sound)
    7: Gaming/Emulation - Nes & PSX for now
    8: Vehicle Automation - time will tell here,,, but will be possible of course
    9: Connectivity - Internet/GPRS/Wifi should all be easy enough
    10: Security - Remote tracking and device disabling - Done it in the past,
    11: Cameras - close to security and other uses like insurance
    12: Profiling - Driver profiles will be a must like in the past (Seats/Mirrors and so on)

    So it arrived (my raspberry pi)... initially i used NOOBs so i could trial the main distributions... Long story short, tested them all.. Raspbian was the one that felt solid and more complete (Which it is the preferred distro).

    Raspbian = Worked perfect, had to edit the boot/config.txt for my test screen (7'' pal/ntsc/VGA) - VGA not supported
    - This only took 2 minutes and then on reboot did not require the HDMI
    - this can also be edited using the recovery mode for Noobs incase you dont have a HDMI screen

    Pidora = Simply did not like this one as much as the Debian wheezy port (Raspbian)

    RISC OS = Installer seemed to fail, did not bother with a second install (cant remember how it failed, was 4am at that point)

    RaspBMC = Installer failed and did not install the GUI (known installer bug)
    - plus had a bug where it would reset/reboot every 30 seconds and blank the HDMI screen)

    Arch = Requires you to install your own GUI, while i love CLI.. Its been to many years since i used linux and for now will require a GUI

    OpenELEC = Same as deal as RISC OS, installer failed and can not remember why/what

    * So in the end i just did a direct flash to SD using the Raspbian image (extra space and one less boot delay by not having Noobs)

    Now to make things a little easier for the learning curve...... - Remote Desktop/SSH/FTP

    I wanted to use a form of remote desktop so i did not have to worry about screens/keyboard/mice and so on while setting up and getting use to a different OS.
    So the first google result landed me on this page http://www.howtogeek.com/141157/
    - A quick skimming over looked like a quick and basic setup, so installed tightvnc-server and went from there.
    - The article covers three basic i needed to remind myself how, SSH / Terminal, VNC / Remote Desktop, FTP / File Transfer
    * Note, their copy and paste script/file has three issues (replace all quotes and the x between the width/height of screen res)

    So for anyone who reads over this thread, hope this gives them a quick starting point as this means you can just work from your windows desktop.

    Just a quick shot showing the modified PC PSU & USB Hub for the test bench.

    A normal PC PSU as most know can be quickly modified to run without a PC and makes a wonderful desktop bench PSU for certain 12v & 5v testing or normal operation. All you have to do for this is short the green to ground.. i've just added top terminals for when i can be bothered finishing it.
    PSU rating (12v = 9amp, 5v = 20amp)

    The USB hub itself was a self powered hub so that was not a good option for the raspberry pi, so simply cut and required the 2 power wires on the hub to the PSU 5v output on the molex plug, this also powers the pi on the molex 5v as well. LCD itself runs on 12v so thats powered by 12v on the molex.

    Checked out RetroPie also and was okay, the SD image itself easily with no changes required.. Using the RetroPie Setup script on the other hand fails due to X still running... Will try this another time when have the time to play around with it.
