Re: xtrail pc install


Nice bit of software ... and free too!! emoticon

So the next question is ... startup and shutdown - what is the plan for that? Will it recognise the ignition going off and shutdown or standby automatically?

Re: xtrail pc install


yeh the Opus powersupply i'm using has an integrated startup/shutdown controller...

it has a shutdown timer so that it can turn the pc off or hibernate after 10, 20, 30 or 60 minutes. ignition/accessories triggers the power supply to turn on. I think it also has a low battery cut out but not 100% sure. the manual is downstairs in the car.

Very sweet!! emoticon

I hope that you can spare some time to do a complete write-up once it is complete, detailing all the parts you used and the rough cost.

I don't know why I didn't think of doing this myself but I have bought a Pioneer in-dash DVD now so I will live with that for a while. Perhaps this will be a future project for me though!! emoticon

Re: xtrail pc install


awesome!
ive been fantasising about this since I got my exy but havent really figured out where to start! ive been vaguely keeping an eye on ebay for laptops with buggered screens, they come up every now and again and a seperate touchscreen in the dash will solve the screen problem but I like this idea better. great job and I hope you can write it all up so we can take advantage of your pioneering work!

Re: xtrail pc install


tja,

Can you provide a link to the PSU? I presume you've also used some form of step-up transformer and alternator to go from 12vdc to 240vac?

Re: xtrail pc install


Anyone who is doing this I would advise you not to run your system using a DC to AC convertor. A computer does not run at 240V so you are converting from 12V DC up to 240V AC just for the in built transformer to drop that back down to the ?V DC required to run the PC!! Don't do this! Apart from massive energy losses you may also get whine on the audio from the 60Hz AC signal. There are DC to DC convertors available, some specifically for car PC applications which give multiple voltage outputs for running the system and peripherals that run at a lower voltage.

The more electrical load you put on the car the worse your fuel economy can get.

Have a read of the following blog pages ...

http://tunertricks.com/blog/index.php?p=40

You will need to read the first page then click the link at the top right to go to the next one, and so on. Not all pages are specific to car computer installs but most are, so keep stepping through. I know that the installs on that site refer to installing a Mac Mini in a car but the same principle applies and there are references to the DC to DC convertors.

no inverter used.. its a 12V ATX power supply from opus solutions.

I would avoid using an inverter in your car if you can avoid it, especially if you are doing any water crossings . You don't want to mix water and 240V.

Also the efficiency costs that going from 12(13V) to 240V then back to 12V, 5V for the pc.

Re: xtrail pc install


yeh i didnt want 240V in the car at all.. the opus PSU isnt a cheap option , but it's clean and easy to install. just give it 12V from the battery, 12V from ignition switch to turn it on, and you have a 150watt computer power supply emoticon

added some more photos to the first post (of PC case)

Re: xtrail pc install


All,

Thanks for the info. I didn't realise there were psu's specifically for car installs hence the 240vac step up question.


240vac and 12vdc in a car situation are equally dangerous. The high current output of a car electrical system is very dangerous even at 12vdc (try holding on to your battery terminals if you'd like to test the theory). I'm not sure why you're worried about water crossings? I presume you'd mount the transformer in the cabin?

[EDIT by NPC73]: Post tidy up
