Hello everybody. I'm new to this forum and also to the car pc thing. The elementary for this build is my fathers. For over a year (can't remmember) we've used a Asus Eee pc with 11 inch screen. Now we've grown out from that and are going to build a real car pc. The car is a Volvo s80 year 2000. The main purpose will be to use it as a Gps and also monitor by ODB. I'd like to use it to play music too but the built in stereo doesn't feature an aux-connection.
We don't like the regular Gps's where you got a like four inch screen or so. As we got this seven inch screen for the right price in surplus we will go with that. I guess you guys out there know that the resistive touch panels are dustmagnets, so apologise for that.
The monitor got vga, two composite in for rear or nightcamera use, audio in and USB for the touchpanel. We assumed that the audio in the monitor should suck, but we where wrong. It is ok for Gps use and better than a modern cellphone.
The motherboard an Intel DN2800MT with atom N2800 cpu. It's a bit overkill but the eee pc did just make it running Windows xp but now we got enough horsepower for HD video too.
The heatsink look small but it will handle the heat from the cpu fine. It has also clearance for the dvd and hdd cradle wich leaves out one ghetto-solution.
The wireless card comes from the original chassi we're using. The card is an Atheros something, it'll work for us. Sad there's no bluetooth on it so we're going to use a dongle. The Ram is 2x2gb Kingston 1066MHZ DDR3 SODIMM, as ram is so cheap these days. There are also tons of other connections on the board that I don't even know what they are used for. But I can tell there's integrated 8-19v dc-dc powerinput.
May I introduce the chassi. An old Asrock ion 330 or something with broken graphics. So the motherboard was recycled and the chassi and other useful parts where saved. And now the come to good use.
The front plasticcover. Behind the ventilation holes there has been an IR-reciver but that doesn't connect to our new motherboard so we'll skip that.
Took the freedom and flipped the image, sry it looks weird. The Harddis a Samsung, 160Gb, and spins at 5200rpm. It's from an old laptop with a broken power-connector not worth fixing. Works for this even if and SSD had been the optimal choise, but not for our wallet. The DVD is original from the chassi better use oit here than use shelfspace.
The power to the drives comes from the motherboards s-ata powerconnector. But originaly (asrock-style) it used a 4-pin atx (cpu) powerconnector. An easy fix with the soldering iron.
The other end of the drve-cables. Perfect length.
The other cables used for the "pc-part" of the project. Powerbutton, pwr-led and internal USB for the bluetooth dongle. The wires for the wireless where former mounted at the front of the case. Now the new motherboard got another layot that don't match that cable-lengt so we need to move them. I will hope that it makes the least impact on performance compared to extend them.
The with of the chassi is a bit bigger than normal mini-itx, but the depth is to short. So we needed to extend it.
We drilled the rivets away and cleaned it up in the milling machine and mounted it back on with soldering, my fathers idea. I didn't know that it worked but it did.
The distances for the motherboard where also on non-standard places. So we made new ones.
The backplate also got milled. It's not that pretty with the old holes left but it will be ues as ventilation holes. Intel is also niceand includes the regular full height backplates but also the half height that we used.
The lid of the chassi. Very clean looking design.
That's it for today
