Recently finished my little summer project.

 

Interested to see if there are others who have gotten sick of standard head units and hooked up a tablet or pc in their vehicle.

 

THE SCREEN:

 

This is a 7" touchscreen w/case for a raspberry pi (bought from jaycar) running off my Microsoft surface 3 that sits pretty in my glovebox.

 

Above the surface, I attached a powered usb hub (purchased from officeworks) that is powered by an inverter (jaycar). This is because the surface only has one usb port and that wasn't enough for my application.

 

The inverter is powered by the cigarette lighter socket. It also charges the surface tablet when the car is on IGN. It is mounted in the passenger footwell (hopefully far away from getting kicked, so far so good)

 

The screen requires a hdmi signal and a usb signal for touchscreen. I purchased an adapter (jbhifi) that converts the mini display port in the tablet to a female hdmi port. The micro usb output on the screen goes straight to the usb hub.

 

The tablet plugs into the hub via it's single usb port.

 

I have a VI-PEC ecu that plugs into the hub via the LINK tuning cable and the tuning software installed on the surface to get a live feed from the ECU.

 

The screen is mounted to a second head unit surround I purchased incase i wrecked it or it didn't fit. Minimal mods were required to get it sitting nice.

 

The other usb cable goes into the sound system.

 

 

THE SOUND SYSTEM:

 

My car already has an aftermarket sound system (amps and sub). My amps power the speakers so all i needed was something that was capable of accepting multiple RCA leads, and was usb powered/ usb audio. The ASUS XONAR U7 MKii external sound card fits these criteria. It's capable of 7.1 surround and is usb audio and powered. A couple of adapters were required for some of the plugs as they are 3.5mm jacks, not RCA. No biggie, jaycar has the goods.

 

The card is mounted behind the screen and plugs into the usb hub in the glovebox.

 

Utilising the ASUS software, the sound system could be tuned to a degree. I've found I'm now at the mercy of the quality of sound files I use for music on the tablet (mp3 etc etc) so the quality differs.

 

The main effort was the screen setup, music was just a bonus for me anyway.

 

 

CONCLUSION:

 

The setup as a whole is way better the my old single DIN headunit. I no longer have radio (what a shame) and have to make sure I turn the tablet on after starting the car and turn it off before switching the car off (just like you would a pc I guess) otherwise it has a s#$% fit).

 

My ability to view and even modify ECU settings is very useful when the car gets tracked. Live temps and values etc.

(I'm far from a tuner so I just peek)

 

I have all normal windows pc functions like Wi-Fi and internet browsing, bluetooth etc (obviously not while driving........)

 

I'm pretty sure you could even get Google maps to work as a navigator if you have the surface 3 with gps. Mine does not.

 

No r34 interiors were drilled into or hacked up in the making of this project. It's all removable and reversible incase it all goes to s%$^ lol.

 

The whole project cost me a few hundred bucks because I already owned the surface 3... I'm pretty sure all the newer surfaces are too big to fit in an r34 glovebox anyway. Smaller laptops may work.

 

 

Thanks for reading if you got this far!

I did this about 10 years ago,  i used a Thermaltake 7" lcd motorised touchscreen that was made for servers that can sit in a pc case,  i mounted that in the dash,  and used a amd mini pc and a 12v power supply from jaycar.

I am thinking of doing another setup now,  where did you get the screen from?  how much was it?  I think i paid $600 for mine back in then.

 

i think i got a video somewhere of it working

 

 

 

Cant see much,  but it was a awesome setup.  It eventually died because I used a conventional 2.5" laptop hdd in it and all the bumps and pot holes in The Republic of Georgia destroyed it...  I never made a new hdd for it as i moved engine from one car to another when the car got to the UAE

Very cool to see that this stuff was still do-able 10 years ago ! Although I suppose that was only 2008 now.

    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
