    Ideas for an Interface

    Hello everyone,

    This is my first post on this site. I have been reading ton of articles and would now like to pursue my own carputer. I have come up with a very ambitious project where I am going to write m own software from scratch based on the Mac OS X platform. What I would like to do is run a dual monitor setup where one screen is a digital dashboard and the other is the main application (music,nav, etc..) So i am lacking a little right now in the creative department and was wondering if anyone could post pictures of their interfaces. Also I don't have much experience with openGL and was wondering what is the best way to make a gauge cluster using it, ie. use photoshop and move images around. If anyone has any advice that would be great.

    Evan

    Why not use a better-supported OS in WinXP?

    That way you can use PCMSCAN or DashCommand, which can be easily embedded in Centrafuse or Roadrunner Frontends.

    Saves you a lot of hassles.

    I have a MAc-mini, but running XP - easy choice, really - no advantage using MAC-OSX

    Try this first - get two monitors running on your Mac. If it is a Mac Mini, you will have to buy more hardware to get two monitors to work. If it is an iBook or Macbook Pro, you can run both the screen and an external monitor but this presents installation issues for you.

    I run a Mac at home with dual monitors but it is a tower unit with a video card that does this. Unless you do the same (way overkill) a dual monitor system is not straightforward.

    The advantage for the PC is that if you build your own, you can install a card to give you dual monitors.

    RoadRunner already supports dual monitors. It has in car gauges and lots of other stuff. I can assure you that you will spend oodles of time just getting the already written software working as you want rather than spending the time coding. This is not an easy beginner project.

    Reason why I am building this from scratch is because this is going to be my groups senior design project for our electrical engineering degree. We are going to do a hackintosh system where OS X is installed on some non apple hardware. we're leaning to go with a VIA nano processor and mini itx board. we're going to use the OBD-II port for information that is not updated constantly like fuel levels and battery voltage, etc... We're going to use a PIC microcontroller to grab data for real time updating of constantly changing data. I would just like some ideas on what I could do for the vehicle's cluster interface.

    I have OSX systems, and none from Apple, so I guess I have hackintoshes too. But believe me, you cannot just pick random hardware and get it to run OSX. The lowest system I have that OSX can even try to install to is a P4 with SSE2 and SSE3 instructions. For stability which you will need since the professors reviewing you will try everything to make it fail to make sure you were thorough if they are worth their salaries, you really need to use a Core 2 Duo and a decent video card. I have found a few drivers for osx video cards and mostly are for integrated chipsets like the 945GM, and 965GM and such. Also with a hackintosh, you cannot just install the 945GM drivers. There are drivers that work for 0x2702, and dont work with 0x2700 or 0x2710 and visa versa. So you should buy hardware based on the stable drivers you find. Just like most laptops (including mine) the intel wireless card doesnt work since there are no drivers for it.

    I can almost guarentee that a via system with its SiS chipset and not full instruction set will not run OSX, and if it does, it wont be stable. Also be forewarned that if your university is a stickler for legallity, and they usually are because they can loose their accredidation, installing OSX on any non-Apple hardware is completely 100% illegal even if using a purchased copy (which you will have to patch anyways to get to boot ).

    yea legality issue I really didn't think of. we'll probably just run the system of one ofo our laptops since the school doesn't gives a lot of money to really make this system something

    Well you can always get a used mini or something off of ebay. Still expensive for what it really is, but it would be legal and cheaper than a full out imac or something. Maybe even find a broken one with a bad HD, or no optical drive or something since I am sure you can get around it since all you want is the OS.
