  • 1995 Saab 900 S- Touchscreen Build

    Hey everyone,

    I am starting a project of installing a computer in my saab 900 with a 7" touchscreen. I think I have it fairly planned out so here it goes...


    1. Intel BOXD945GCLF2D Intel Atom processor 330 Intel 945GC Mini ITX Motherboard/CPU Combo

    2. 80GB Macbook Hard Drive (seagate Brand).

    3. 2GB Stick of Corsair DDR2 RAM

    4. Carnetix CNX-P1900

    5. Lilliput 7" Touchscreen

    6. I have already built a volume knob out of an old PS/2 Mouse.

    7. An AMP to power the speakers

    If anyone could let me know if this set up will work (specifically if the power supply will connect to the mobo) t would be greatly appreciated. Also i would like to know if I will need anything else.

    PS/2 Mouse

    Here are a few pictures of the mouse I built!

    At some point I will paint the knob black, possibly with the word saab in the middle

      Purchased Parts

      So I purchased a few items tonight and just though I would update the thread.

      1. Motherboard- Intel BOXD945GCLF2D Intel Atom processor 330 Intel 945GC Mini ITX Motherboard/CPU Combo

      2. 500GB internal laptop hard drive 2.5". The plan is to install the 500GB into my macbook, use my 160GB that is in my macbook as an external device for my carPC, and use my friends 80GB from his macbook to connect to the carPC.

      3. Nippon Labs 2.5" SATA to USB 2.0 External Enclosure. This will be used for the 160GB HD, which will contain music and other files I want to transport.

      That is all I have for now... the only things left on the list are the PSU, touchscreen, and amp. oh, and I might pick up some 5 1/2" speakers to add to my set up somewhere from a guy on the forum.

      I will let you guys know when I get the parts and I will try to get some pics up as well.

        general question.

        For the motherboard i am using will I need any extra fans if I am going to be putting it in a plexiglass case? and if so, what size do you recommend?

          So it's been a long time since I have updated this post, just been really busy lately.

          I am still working on the computer. I now have it put together and running in my room.

          Below are a few pictures of the parts laid out on my desk (I am using an old power supply that I had laying around to get the system up and running):

          Next are a few pictures of me building the case (not anything special, just something to protect and 'conceal' the computer from dust and harm. It will be hidden anyway:

          Here it is put together and running:

          Got windows 7 installed

          I only included 9 pictures because that is the limit per post, so let me know if you want to see more!

          Next step is buy the touchscreen and car powersupply. Once I get the touchscreen there will be more updates as I fabricate the dash to fit the touch screen just right!

            So I am debating between power supply's now. I need some help deciding.

            First Option: Opus Solutions 120W Intelligent Vehicle DC - DC Power Supply

            Second Option: M2-ATX 160W Intelligent DC - DC Power Supply

            I believe that both of these should have plenty of power to run my computer, and I am leaning toward the M2-ATX because it is practically half the price.

            Can someone help me out and tell me what else I will need inorder to 'power' the power supply. They both come with connections to connect to the computer, right?

              -HERE- is some power info for the DG945GCLF2. the hd is not 500 gb but most hd require > 1 amp

              my thoughts on the m2 are mixed... its works and its cheap but i wish i had read about the m3-atx before i invested in the m2. 160w is good to provide power for a few monitor but for the atom boards i feel its over kill. the m3 has a configure-able shutdown controller as well as its super small. i dont know much about opus psu, sorry. and yes they come with connections. if you want to bench test whichever automotive psu you get you can use the psu you are using now for a 12v power supply.

              As far as heat and a second fan goes, it depends on where u keep your final set up. ive had mine in-dash for almost a year and i added a fan to the processor cause temps would bounce between 50 - 60c after a few hours but im not sure how accurate speedfan's temp are. the same board out of dash doesn't need any fans and does fine. sooo ... as they say, "location, location, location"

              oh and keep in mind with your custom case there that you should maintain a clearance of about 1/4 inch ~ 10mm on the bottom of the board, but i think case manufactures give about half that, your call.

                So I got the touchscreen yesterday. and I have since, installed the drivers, tested it, and have now taken it apart. Here are a few pictures to go along with my adventure.

                A couple shots of the screen, running windows 7:

                Screen after it has been unscrewed and cracked open:

                Front Bezel:

                Lilliput Logo removed:

                I hope to be getting some bondo tomorrow morning and am going to work on it at some point this weekend hopefully. I will keep you updated!

                Let me know what you think!

                  I did some more work today and I am just a few steps from installing the touchscreen in the dash sorry for the poor quality, but they're just cell pics.

                  Firstly I did some dremeling and removed a bunch of parts of the dash:

                  Next, I drilled a hole for my Volume Knob that I recently painted:

                  After that I did some sanding and dremeling on the SID to make the touchscreen and SID fit into the dash. I situated them in the dash and made sure they fit right:

                  Then I took apart the SID and taped both the SID and the touchscreen bezel in place. I went ahead and added some bondo to fill the gaps:

                  That is all I was able to get done today. next step is sanding the bondo. Then I will bondo and sand until I get the desired look/smoothness. Once that is complete I will paint all of it.

                  Let me know what you guys think!

                        Got some more work done...

                        I got it sanded down and used some more bondo a few times:

                        After sanding it down I finally painted it. You will notice that on the left hand side the seal cracked and is showing through the paint. I have not decided if I am going to redo it now or install the dash anyway and wait to refinish it later this summer.

                          I was unable to install the new dash, but I got the old one out. I am going to need to dremel some parts out before it will fit right. I figured that was going to happen. anyways... here is a photo of what I did as a temporary fix:

                              i think it looks really tidy so far, liking the case and the dash. shame about the tiny little crack really. the mouse volume was a really great idea, i didn't have a clue that you could do something like that. the only (personal) preference i would have is to make the mouse volume knob smaller. when you wire it up how does it all work, i.e where do you wire it to, and if any software is needed?

                              well done!
