VOLVO S80 CarPC Work in progress
In fact I'm old user, but I made this acc because I want to keep the identity of the car hidden. I got an unique main nickname, and placing it in google gives you my full identity, my cars reg numbers, ID card numer, phone and so on. So i decided to make this nickname for showing the project. I'm from Bulgaria, and I really don't want my windows to become broken by robbers, you know.
So admins, and moderators - don't judge me for multiaccounting. You could dell my old acount (registered in 2010) if you wish. PM me to tell you the exact nickname. Thanks for understanding.
I plan to use a genuine VOLVO RTI screen. Errrr in fact i need just the box + up and down mechanics.
Here is a full gallery of it while i was disassembling it: VOLVO RTI Screen
The main monitor will be (is) an cheep e-bay one, with no box. Just the LCD matrix + controller board. Of course a suitable touch pannel for it and a touch pannel USB controller.
Here they are:
Temporary, i made a box so that i don't break it by mistake:
The screen is 6.2 inch wide. But the place in the genuine RTI box isn't enough, so i'll need to mod it a bit - to make it 2 sm wilder.
Here is what i mean:
Of course here i've just cut the front plastic face of the genuine RTI screen. I'll need to mod the back one and the metal parts too... a lot of work waiting for me:)
Controlling the up and down. I made a controller board (simple one, with no chips). I can't find the shematics right now, but i could search harder in case somebody is interested.
What it does: it's will be powered by constant 12v in the car. When the computer is ON it forces the screen to go up. I'll be taking a signal when the PC is on by a USB. When the PC is ON, there is power in USB ports (in my case). There are PC's that aways gives power to USB's. For some of them this could be set in BIOS setting, but in some can not. However in my case I'm fine with this.
Here it is in action:
Don't mind the eeePC. It's my old plan but now:
I got an Intel DN2800MT. It's powered directly by DC plug and is rated to be fine in the whole range of 9-19 volts. Sounds fine. Not tested in the car yet.
Link to Intel's web site with full description of the board: DN2800MT.
I'm still thinking how to power it in the car. 1. Direcly plugged to the car installation. 2. Powered by a regulated PSU. 3. Dual battery install. 4. A combination ot 1,2 and 3.
I'm happy to hear your oppinion.
3. Hard disk
It's a 64gig SSD made by Transcend.
I tested it with ATTO benchmark, and it gave me 60mb/s write and 140mb/s read speed. I'm happy with it.
4. Memory (RAM)
In the pictures above you could see the mainboard with attached a 2gig SODIMM, but it's there just temporary. I'm waiting to arrive a set ot 2x2gig. It's the maximum supported by the mainboard.
I got and old bluetooth device. I know, it's not the best out there but for now it's fine (i guess)
It's called GLOBAL BT308
6. Input devices
6.1. Well, I got an sonny remote RM-X5S. It's wireless. I don't care .... :)
I'm planning to mod it using a controller of an old USB keyboard. This way i'll use it's convinient box but it will act as an USB keyboard.
What is inside:
This idea is not new - i've seen many projects making arcade controllers by this method. Just I'll be using the Sony remote instead of the big switches :)
6.2. Probably an mini bluetooth keyboard will be good idea, but will see. (additional, the above mod remote + keyboard is different thing)
6.3. Well the touch pannel itself should be mentioned here as it is input device in fact :)
6.4. An usb bluetooth dongle should be mention here, too. It will be used for connection with the GPS and with my phone.
I'm really happy with the quality of the sound given by the factory HU-601. I plan to keep it and use it. All I need is a AUX IN. Here in Bulgaria I got a friend who made a AUX IN for VOLVO HU units. It acts as cd changer ot rti or TV - whatever in your car is free. So all i need is to switch to that channel from the HU and i got the sound from the PC. There is one more thing - this way i don't need a radio for the CarPC :)
8. Rear view camera
The controller board of the LCD supports auto reverse switching. Cool :)
All i need is a camera. I don't have it yet, but I found that there are some Sony ccd's mounted in box for the license plate light.
Camera in eBay
Does anyone of you used these? Any feedback and reviews will be highly useful for me.
One tought: Well the LCD controller supports auto reversing, but what if I need to park in tight place and put reverse, move 20-30 sm, put 1-st 20-30sm, again reverse and so on... I guess i'll need some kind of controller board with delay for .. 5-7 secs. There is time, i'll think about this, but again - i'll be happy if some of you give me any kind of decision about this.
Well GSM operators here in Bulgaria gives usb gsm modems for free of you sign a year contract for their services. I guess that will be.
But! An half lenght miniPCIe WiFi card will be placed on the mainboard, so that i could connect to the car from home PC trough home LAN. Update music, make some changes, tests, remote desktop and so on.
10. Car diagnostics
I'm not a fan of online data. I got a DiCE diagnostic tool. It's the VOLVO's genuine diagnostic tool used by the dealer. I'll install the needed software called VIDA and i'll use it separate of the front end, only when a need a real diagnostics, code cleaning and so on.
It's a CD changer right?
well... it used to be ...
I placed the plastic cover just for the photo. That's why I didn't close it proper. It will click and will stay propper.
Some info: In VOLVO's in the trunk there is a mounting for two CD Changers. One for 10CD's - it's for audio CD's. I got it, and I'll keep it. I got some original CD's so it will still be in use from time to time. The other CD Changer is for 6CD's and is reading data disks with maps for the RTI Unit. I don't have RTI unit installed in car, so there is free space on this mounting bracket for the 6CD Changer. In the picture above you see i've taken an 6CD changer from junkyard and mod it like a PC Case. When everything is mounted in the car you won't even guess there is CarPC install :) That's the main idea.
Well the PC Case itself is not finished. I'll have to place at least 2 fans, but it's not a big deal, you know :)
Well that's the main idea. I hope in the next couple of months all this will go IN the car and will be working as it should.
I still got to think about some stuff...
1. Power on/shut down control
2. Powering the mainboard - regulated DC or not, dual battery or not
3. Controller for RearView Camera
4. Powering some USB powered hubs
5. WOL (WakeOnLan) somehow. WiFi won't work
6. Finishing the monitor assemble.
and some more which i don't remember right now.
I hope you like it and I'll be happy to hear your opinions and advices.
