    Mac ideas

    Hi there

    I've been reading for a long while and now with my restoration coming along mechanically I'm now turning full time to the Mini setup.

    I've one or two questions as to what I can do with the Mini. I'm still looking into the standard stuff - AMP is looking really nice. If anyone could give me some ideas about the other stuff - or point me in the right direction on what to search and read up on, I'd appreciate it.

    - Some of the more specific stuff I am searching for are how I could control interior lighting via the Mac and a rear panel made from Qprox parts. Interior lighting will consist of ambient light plus 6 spots. Would this be difficult or possible via a small written program? I'm planning on also rigging two driving lights onto the rack for camping and would like the Mini to control these. Most of the lighting will be used both with the ignition on and off. Speaking of which, is there any way to abort the shutdown/suspend of the Mini when the ignition is turned off so as to keep it running on the leisure batteries? Perhaps with a button push before ignition of to engage the leisure batteries?

    - Has anyone looked into tire pressure measurements? I'd like to use run-flats and would like to write a small program that would take over the dash screen with a warning if a tire has a leak, plus have a normal page to view showing the tire pressures and temps.

    - Is OBD developed enough for the Mini yet? I'd like to build a circular screen into a pod mounted unit to resemble a large tach, but it also serves the purpose of showing other engine parameters. How many seperate screens can the Mini control? A dash mounted main display, a rear viewing cinema display and the "tach"? Or is that too many?

    - Finally, I'm planning how to split audio, or whether it's possible. So far I've been brain storming about having the option to play music through the main speakers but be able to run a DVD through the rear screen and the sound either through the rear speakers or through wireless headphones.


    I know a lot of this is probably basic stuff, I've tried to find it via searches, so if anyone could point out some frequently used terms for the above stuff to aid my searches I'd appreciate it. I'm brain-storming ideas at the moment and have about a year to build up the bus with a stripped shell, so most fabrication stuff should be possible.

    Thanks for listening, y'all!

    Another idea

    How many cams can a Mini control - or is that only limited by the number of inputs? Am thinking of putting two in my split bus - one in the rear and one in the front. I'd like to use them for front and rear viewing out the windows (i.e. reverse camera, etc...) and recording clips of driving (hey, it's a hippie bus...). I'd also like to be able to spin them inwards to use with messenger.

    I'm looking to make a tachometer mount in the same style as the iSight, and there are going to be a lot of brushed aluminium accent panels.

    I know some of these ideas are a bit rough and reaching, but still brainstorming what will be and won't be possible...



    If anyone has any other ideas that they think might be cool in a bus, I'm open to suggestions - you guys know a lot better than I do what works and doesn't as I'm still learning as I go...

    Thanks again to anyone who reads this, I'd appreciate your input.

    The Mac isn't as developed as the PC in the control of external devices. However, phidgets are available and much of what you ask about may be addressed through the use of phidgets and the input/output are accessible via code on the Mac.

    As for multiple audio outputs, I haven't seen it done, but there shouldn't be any reason you can't. However, you have a dedicated DVD output requirement. Just buy a DVD player and plum it to the rear screens and be done with it.

    Multiple cams - again, not necessarily a problem but I haven't seen that done either.

    OBD - nothing really developed for Mac.

    Circular screen - never seen one before.

    A lot of the things you are asking about are pretty big projects in and of themselves, each one will take you a couple of months to figure out, unless you are pretty good at hardware/software and have a lot of free time to dedicate to it.

    On the plus side, the Intel Macs run Windows so if you need/want it and the program runs on Windows, you can use that to sub for shortcomings on the Mac side.

    Take a look at this site: http://www.connect2car.com/c2c/mfc.php

    They say you can control all accessoires. They support Mac OSX

    Yes, this is possible. The easiest way is some serial I/O controller to which you can write using standard methods of writing to a file. Depending on the hardware, you may need an additional USB-RS232 adapter. When choosing the right product, strongly prefer products with FTDI USB chip. They are known to work fine under OS X.

    and off. Speaking of which, is there any way to abort the shutdown/suspend of the Mini when the ignition is turned off so as to keep it running on the leisure batteries? Perhaps with a button push before ignition of to engage the leisure batteries?
    Install a valet switch parallel to the ingition sensing wire.

    - Has anyone looked into tire pressure measurements? I'd like to use run-flats and would like to write a small program that would take over the dash screen with a warning if a tire has a leak, plus have a normal page to view showing the tire pressures and temps.
    Yes, I have looked into that, but:
    - 1. most aftermarket solutions are a bit too expensive
    - 2. I have not found one with easily usable interface and I am too lazy to patch into LCD outputs and do all the conversions.

    - Is OBD developed enough for the Mini yet?
    Not yet, wait about one month.

    How many seperate screens can the Mini control?
    Generally one. Using some tricks like a cable simulating one large display and splitting the image you might be able to use two VGA displays. If the tach is a simple mono-color display, you can probably use USB or RS232 to control it.

    - Finally, I'm planning how to split audio, or whether it's possible. So far I've been brain storming about having the option to play music through the main speakers but be able to run a DVD through the rear screen and the sound either through the rear speakers or through wireless headphones.
    That is possible by either playing around with Core Audio or using Audio Hijack (in which case you will have to use a different application for each source).

    Thanks for the responses. Jirka and Bugbyte, I've read a lot of your posts and appreciate the wealth of knowledge you both have.

    My time frame is quite long - I guess around a year before I start fabrication into the car. The car needs strip and resoration so that's why I'm looking at this now for access, welding, mechanical modifications. As you say Bugbyte, I think it's a lot I'm perhaps beyond my capabilities. Mechanically I'm proficient, but software and so on is an area I have no experience, although I am now aiming to learn Objective C and Applescripting.

    once again, many, many thanks for the responses.

    but no OBDII, what jerks.

    seriously

    OOOH i can turn on my neons, yeah well AFAIK neons pretty much come with an on/off switch, usually...

    gimme a break, all this "effort" and not an ounce of visual OBDII?

    Different people, different priorities :-)

    Anyway - there will be OBDII software for OS X within a month. I will post some details (and more) by the end of this week.

    Once I googled your mac project all those years ago (and how I came upon mp3car.com)...well i mean I googled and found your site among the hits.

    I always knew YOU would be our Saviour.

    I assume the details will include the hardware specs and some software that could possibly be used in other front ends?

    as in, its not standalone.
