    Carputer plans and questions

    I have a 1997 Toyota Corolla Seca Conquest. It has the standard (standard AFAIK, it was in it when I bought it 2nd hand) Clarion Head Unit and a 6CD Stacker.

    The stacker worked fine for a while and then all of a sudden it started to "stutter" and then cut out after about 5mins of use. So I have pulled it out with the intention to get it fixed but I haven't been to town for a while, and when I have been I have been either too busy to take it anywhere or forgot to take it.

    ATM I am using my iPod through a tape adaptor for music, but it is a bit of a pain in the butt.

    I have wanted to build a "carputer" for ages. So I think now is a perfect opportunity.

    I already have an AMD Duron 1.1Ghz, with an ASUS A7V8X-MX (mini-atx), and 256Mb PC2100 DDR ram, and a 30G Quantum Hdd and a Pioneer 105S Slot load DVD-Rom

    I still need a PSU (preferably a DC-DC PSU, which I may build myself if I can find a decent ATX schematic), touch screen LCD and a case which I will build myself probably.

    What I would like to know is where can I find a decent DC-DC PSU schematic that would suit my requirements?

    Also anyone who has the same car with a carputer, how did you mount the screen? I will try to take a photo when I get home from work. I might have to get a shorter gear stick (not that thatís a problem (I planned on doing it anyway)).

    Where abouts in Australia can I get a suitable size touch screen LCD? I have two options, as I see it, for mounting the screen. Option 1. is to move the existing head unit down to the place I stick all my CDs and stuff (I'm sure it is a double-DIN bay) and put a blank plate below/above the head unit and then install a touch screen that is a fold away one that mounts in a single-Din bay. Option 2. is to leave the head unit in the current position and then mount the touch screen in the double-DIN bay down in front of the gear stick.

    Is there any open-source VB or VB.Net car player front ends out there? I would like to make mine custom. :P

    ATM features I have thought of are:

    -To play mp3s, WMA, mpegs, divx, avi, etc
    -when a cd/dvd is inserted check the content of the disc, if it is a dvd play it, if it contains mp3s, ask either to copy to hdd, or to play straight from disk, if it is audio cd play it.

    This is for further down the track. I have a iPAQ 4150, which I could possibly also use via either BT or WiFi use as a remote (but I still want the touch screen as I don't want everyone using my PDA ) also when I get the money I wouldn't mind buying a BT GPS with software and maps for my iPAQ. It would be cool if I could put the GPS in the car too and use the GPS with the carputer, is this possible?

    Also is it possible/hard/easy to talk to the headunit via the stacker cd cable. If is it is i would like to use it for the sound in and if it is easy enough to send the next/previous, fast-forward/rewind, and if it easy enough to somehow use the chose cd (from the 6 cd stacker) to chose between 6 playlists

    I took a few pics of my dashboard. http://modding.birdiehq.net/carputer/images/

    Please excuse the mess inside I haven't washed or vacuumed it for a couple of months as we are out of tank (rain) water and the bore water leaves a stain on the paint.

    as for the psu, i think the concensus is that youre better off buying an Opus, which has all the on/off controls etc built in - this will prevent you from accidentally flattening your battery etc. you can get them pretty reasonably from this site, or jsut google Opus - theres a fair few suppliers for the uk, so i assume itll be the same for you.

    as for the screen - take a look around for makes - i think lilliput is a widely used one on here - again, i wouldnt know about Aus, but google it, and im sure you will find one - else you could see what shipping from this site would be - they may be able to help.

    personally, id mount it next to the gearstick, as it requires less moving of stuff, and it is a bit more hidden from view of thieves - you wont be using it all that much whilst driving, so it should be workable from there.

    besides, if you bought the kit for that psu from that site, it would end up costing you more than the opus 90W and real close to the 150W. Just do it.

    BTW, your mobo from asus, isn't a min-itx. It's ATX. Just thought I should let you know. M-itx mobos are around 6.7" squares (17cm exact).
    If you didn't have fun when you were living, were you really alive?

    I will look into the PSU a bit more, I am not sure if building it myself would be cheaper (or worth the trouble) or if i can get all the parts in Aus? The Opus would probably be ideal if I could find a Australian Supplier.

    As for the screen, I have been doing a fair bit of reading on here and I thing you are right that Lilliput is one of the main ones. I ended up finding an a supplier on Ebay that sells a 7" Touchscreen VGA LCD for AU$345 which probably isn't too bad, but at that price I will have to leave it a little while and pay off some other bills first.

    I think the Double DIN bay in front of the gear stick would probably be the best, as, as you say it would a bit more hidden from the view of theives, plus it will look more factory than having a slide out one where the headunit is atm. I won't be using it a great lot while I am driving, maybe the occasionaly skip song, or change of the volume but thats probably about it.

    As i said above I will look into the PSU and the prices.

    I think you should reread what i said, I said it is a Mini-ATX not mini-ITX
