Tablet is definitely the most elegant solution. Pity the link ecu doesn't have obd2 output, or an android companion!

I'd go with a reputable brand of windows 8 tablet - there's nothing worse than a cheapo touchscreen or system!

USB OTG cable: http://en.wikipedia.org/wiki/USB_On-The-Go

Most newer tablets support this. I don't know if you can charge at the same time though - I would imagine that you can't as it would need to provide power to things like USB memory sticks to work. So, you'd need a tablet that has either a separate charging port or 2 USB's.

From a quick Google, there doesn't seem to be an Android solution for the Link ECU's, I doubt there's an iOS one either. So you'd need a tablet that runs Win8.1 (NOT Win8 RT).

You can get a OBD2 adapter for it, it's also bluetooth, but I'd rather just run a usb into the cabin, that was there's no lag with readings etc, you can see every sensor you've hooked up to the ECU, You can have it all set as gauges as well.

This is something I knocked up in the link software, the gauges will change values once a sensor is hooked up, I'd maybe not have as many either, you can completely customize the sizes etc to suit what you want, these also operate in real time :D

there are actually tablets with full size USB ports on them, I'm not sure if you get them in 7/8 inch though, I'll do a fair bit of research before buying one though, I actually have a friend who has a windows one so I should hopefully be able to "try before I buy" :) Failing that, I could get the OBD2 adapter and have it running through bluetooth, my fear with that is that bluetooth can be a funny critter when things go into sleep mode etc....hard wired is always better in my opinion :)

For android, part of the software solution was an extra ability to have usb host AND charging simultaneously. it's called USB ROM and its associated kernel - as far as i'm aware, on android at least, it is the only ROM to have this feature. it also has 'fast charge' that is necessary to keep the tablet at 100% battery while also using 100% system resources. if it wasn't a fast charge, the battery would deplete even though it was being charged.

if you can get bluetooth obd2, i'd definitely recommend going android and Torque. it offers the same customizing with no lag.

if you can get USB OTG Y fast charging + host mode in windows easily then it isn't problem.

5A stepdown charger I have my cigarette lighter 12v wired into to give me enough current for the tablet fast charging: http://www.ebay.co.uk/itm/like/111473997718

The torque and (apple equivilent) Rev, aren't meant to be anywhere near as good as the G4 software, It's cool, i'll find a way around this, After a wee bit of reading it seems that a "powered" usb hub is the way to go :-k If i'm honest i don't know enough about it yet, worst case scenario is I get a tablet with a couple of USB ports.

If you really want to run windows look into Surface Pro tablets. Touch screen, tons of CPU power and running Win 8.1 +. Seems it would solve your touch screen / OS problem.

USB ports on proper motherboards are powered, so can drive unpowered devices (usb sticks, wifi adapters, etc). I have a feeling the mini/micro USB ports don't supply power - just so you're aware.

I'm using quite a few USB devices - i had to put an extra 4 port usb card in the box.

Cheers man, I have read that a powered usb is the answer but it seems a bit too simple. Another option i read about was some kind of Y connector the. A powered usb hub :( i'm gonna have to do a lot of reading about this.

I don't think so, only 10.5' and 12' on the newer models. They are very well built however running I7's with full USB3 slot etc.

Toshiba do an 8inch Windows 8.1 machine with a quad core Atom processor paired with 2GB RAM. It's not the beefiest, but it's a lot cheaper than a surface and may be adequate for your needs in terms of processing power. I don't think they have a full size USB port or multiple ones though.

It's cool, I have it sorted, the HP stream 7 is literally a perfeect fit and it's only £75 new from HP! I also found a OTG cable that supports 4 usb ports and charge the thing it the same time :) I measured the back of the trim where it's to be fitted and it literally is a perfect fit :) Gonna order the Stream on Monday :)

Hope this info helps anyone else wanting to do it :thumleft:

Hey folks, just a quick update, got all the stuff ordered, the Stream 7 is apparently quite fussy with which usb hubs it uses, I've done quite a bit of reading about which work and which don't. Oh, and by work I mean provides extra usb ports while simultaneously charging the tablet.

This one works but only has 2 ports.

http://accessories.us.dell.com/sna/prod ... 3a1f4885fe

This one has 4 ports and apparently works too, however, i can only find it on this site and it's gonna take 15-29 days for delivery :shock: :shock:

http://www.aliexpress.com/item/Universa ... 09573.html


Here is a link to the Stream 7 as well, this is definitely the best fitting tablet for the trim of the Mr2. it's pretty much bang on, I'm looking forward to setting this up now, I'm just worried that for some reason the tablet can;t speak to the ECU which is the whole point in getting it :( I was recommended it by a friend and surprised to find out that it is the cheapest (branded) tablet made, I think it's also the only 7 inch one that runs the full version of wondows 8.1 (not Windows RT like the mobile phones)

Re: [All] [Generic] Car PC

riiiiiight, So car PC gurus i need your help, The tablet CANNOT be controlled solely from the screen.

This leaves me with a couple of options, I could simply stick it to the front of the trim, this would get me easy enough access to the power button and volume buttons, It would also leave the usb and audio wire exposed, I am not keen on this option at all, this is plan C.

Option 2 is much the same as option 1 but I fibreglass the tablet in to hide the wires.

Option 3, I;m not sure is even possible but what I'd like to do is mount the tablet in the location I wanted in the first place (neatly behind the trim so all you see is the screen and nothing else) but to do this I want to relocate the tablets power button so it's on the cars trim somewhere. This is a fairly simple process on a PC but tablets are tiny :( Anyone have any ideas about doing this??

Just to add the tablet runs great and windows 8 is ideal for a car pc, There are some media players that work really well, VLC have released a new touchscreen media player which is stunning however, you need access to the volume buttons, everything else about it is touchscreen except the volume, how frustrating!!

Could you leave the tablet on full volume and then use the software volume controls or OS volume controls instead?

This reminds me of my laptop which has dedicated volume controls that I end up leaving on full volume.

Alternatively if the tablet is hooked into your Stereo couldn't you use the stereo volume controller whilst leaving the tablet on full output?

Apologies if I'm stating the obvious and there's something I'm missing :thumleft:

there's no volume control in the new VLC media player other than the buttons, and it's also full screen, it's basically designed for a tablet, after thinking about it i'm gonna just leave the tablet attached to the outside of the trim so I do have access the buttons anyway, it's the only real option if i'm honest, you also need to have access to the edges of the screen (I realise this after playing with it for a bit) so you can close apps etc, well, so you can use the swipe functions, it won't look bad mounted the way i'm thinking just not as sleek as it could have been, I suppose the silver lining is that I can take the tablet out the car when parked in a particularly rough area or something.

To quickly get back to media player, I think i'm gonna use a wee interface called Ride Runner, it's developed specifically for car PCs and is fully touchscreen, it has everything you need, the new xbox music player is fairly sleek as well, I won't be using VLC due to the fact that you cannot have music playing while you switch screen i.e. it doesn't play music in the background so if it's impossible to have the G4 screen running at the same time as having VLC playing music, it is however a beta version so hopefully the iron out the wee bugs, it is a very very nice player apart from these wee niggles :(

I've built a full install tablet with volume control and access to the OBD2 in my car. I've even added extra usb so Ican plug multiple things in. Works really well.

this is how I originally wanted to mount it, but fill in the sides so only the screen was visible :( However, the power button thing is an issue, You can get external buttons but it means opening it up and soldering etc and I'm not sure I'm keen on doing that.

And this is how I'm gonna have to mount it, I've ordered a case for it so I'm going to stick the case onto the trim (cut it to size first) and then the case will hold the tablet.
