Huawei MediaPad, in my car! - Huawei MediaPad, T-Mobile SpringBoard

Hi everyone, just wanted to share my car tablet project with fellow MediaPad owners. I've retrofitted the tablet into the stock navigation hood of my car. :laugh:

Nice work!

Nice. I've done something similar with it in my car too.

Nice setup! I see you used an Arduino BT, is that the best way to interface an Arduino with Android? I'm using an Arduino Uno what options do I have to interface that to Android? Right not I'm using the charger state change to turn the screen on and tasker orientation change to turn it off.

When I first created that program yes. But if I tried it now I would look into a usb connection from the tablet to the Arduino. A bluetooth Arduino is really expensive ($150)! I think they have wifi ones also. The bluetooth is mostly reliable. I did have to make my program disconnect and reconnect every 5 minutes or so. That was an issue I had on a Galaxy Tab though. Not sure if it's necessary on the Springboard.

How do you power it? With navigation battery goes down just in 2-2,5 hours. I tried to use 2A USB charger, but it doesn't give much difference. It's still goes down very quickly...

That's interesting. I don't have that problem at all. I'm using a generic 2a usb charger from Wallmart. Maybe you're using the usb jack to charge it? I cut the end off and soldered it to the power jack.

My charger only runs at 1A and it charges very quick. In my setup the tablet is charging continuously even when car is off, its basically always at 100%.

I would attempt that level of awesome, if it didn't mean possibly killing lots of people in my negligence. I would have to drive a bright yellow nerf car lol.

Wow. That is really cool. And the video was even cooler. Nice usage of arduino and getting everything to show within the bezel. But do some of the programs on the tablet not play well with the shortened screen real estate?

Thanks! The ICS on screen buttons aren't accessible, but since that area is always reserved for them, everything I've tried so far works.

Desk charger/sync cradles.

Has anyone here tried one of these cheap ones from Hong Kong?
They are cheaper than the nearest option, and come with the right plug too.
It can't be expensive cause it consist only from ac/dc adaptor, usb plug and battery charger. I think it's right device.

I'm sure it is, I just wondered if it's likely to be good quality.
Tell you what, I'll order one and report back here once I've used it.
As promised, I bought it and here's the verdict.
Basically, it does what it says on the tin. There was a slight problem with the usb connection, but that was always the case with this computer unless I use a particular lead. Using the lead that came with it, it wouldn't connect. but using the one I normally use it works fine.

Having used cradles before, this one is slightly more awkward to connect but that's because it uses the usb connector. Previous ones have been spring loaded contacts and the pda would just drop into the cradle. This one requires a little force, but nothing major.
I've yet to determine if the charger works as fast as the original one.
All in all, well worth the money.

Hmm, seems I spoke too soon. The PDA won't charge unless the computer is on.
The 5V adaptor plugs into the back of the stand, as does the usb lead. Either of these will bring on the blue LED on the base, but the usb lead lights it brighter. I suspect there may be some problem with the 5V from the adaptor.
I shall investigate and report back (if anyone's reading this...)
charging with PC off
Hi -- I think I've got the same charger as you, and mine seems to charge fine with the computer powered off. . .
Alan
Having investigated further, it appears that the +5V from the charger and the +5V from the USB are linked directly. This means that with either one connected singly, it's fine, with both connected and the PC on, it's also fine.
But, with the PC off the +5V from the charger is fed back through the USB lead into the PC which pulls down the voltage somewhat.
I discovered this when I turned off the PC and noticed some front panel lights glowing slightly. I unplugged the cradle and they went off, and the blue LED on the charger became brighter.
dock
hi,
i've got the same "hong kong" dock as xmastree.
I think this is a good dock, simple and cheap.

contact 1 is about the cradle.tape contact 1 then connect the plug.
look,system show cradle setting ui!
so,diy cradle is so easy:
just make some cradle size ok,
tape the 1st contact of power plug,and set it on the cradle.
done!
it will work same as official cradle
Hey!
First of all: That sounds really great!
But I do not have a lot of experience with such things so I do not have any idea how to construct such an adapter (ok, the technical way is clear so far, but how to construct the case of the adapter?)...
Does anyone have an idea?
Thanks and kind regards

Let me know where you can get the DC plug from, as, I'd like to make a car adaptor, as far as I know, it's a Sony Special and not available (yet?)!!!
Wow, this is a great idea, <robin>! Thanks!
I tried this, and although the cradle function is activated on the tablet (as shown in the OP), it didn't charge after I taped that pin 1 on the charger plug...

Use old lapdock as a tablet dock?

Backstory:
I have a lapdock from my old Atrix that had the LCD go out on it. I was wondering if it would be possible to just use it as a battery, keyboard, and usb hub for my Nexus 7. I took apart the dock to access the micro usb plug to go into my Nexus 7 but have no use for the HDMI. However the lapdock is enabled when a device is plugged into the hdmi.
Question:
How do I enable the lapdock without anything plugged into the HDMI.

Can you get any pictures? It would be helpful.
If you the cables out, have you tried plugging the microusb into the nexus 7 and the microHDMI into the phone(to power it on) to test whether the nexus 7 even detects the keyboard, mouse, charger of the dock?

I Don't have any devices with micro HDMI anymore (Atrix went to craigslist). I ordered an adapter for regular USB but from China so who knows when I'll see that.
The nexus 7 doesn't support HDMI out at all. Google confirmed that... What you could do is make some like of dummy or I read somewhere to short some wires... Read before you do anything though...

I know the Nexus 7 doesn't support HDMI. Thats why I'm here asking if anyone knows how to short the HDMI. Having trouble finding anything on it.
sorry for digging and old thread but until now im using the lapdock as otg hub, a keyboard and track pad. i have to remove the lcd screen since i have no use for it. very useful indeed up to now 2018. i usually use this setup playing pubg mobile. i dont a tablet but probably it also works
if you have a broken lapdock lcd, then you can have mine for free. except you shoulder the shipping of course

Black MHL To HDMI HDTV Adapter OTG Card Reader Connection Kit

Hello Guys,
I don't know is should start this thread or not, just thought i should share this amazing device.
Black MHL To HDMI HDTV Adapter OTG Card Reader Connection Kit
It let you connect to HDMI without external power, also if you use external power you can use HDMI and USB hard drive at the same time, it is just really really amazing, Sammy has really improved their MHL and OTG support.
Note: I am using this device on my Note 3 N9005 I am not sure about other devices

Only £6.59 free postage from Amazon, just got to way couple of weeks to get it delivered, but its worth it
Black MHL To HDMI HDTV Adapter OTG Card Reader Connection Kit
Mhl 2.0?
Iv been dealing with these for about a year now. From my s3 to my note 3. With the s3 it's 2.0 so you have to provide external power but these things are the tits when it comes to the note 3 with 3.0 you can run USB and HDMI without power. I play games and use it for work with all wireless accessories it's awesome. Supports 1080p at 60hrtz. We sell them in our repair shop and on Ebay. Not often though as "normal" people don't see the capabilities of this lol.
Go buy one their awesome.

Is there something like this that has a port for charging? I wanted something like this to hook up to a monitor or an HDTV so I could play my emulators on a big screen.

It's not immediately apparent, but the device pictured (and others like it, one of which I have) do have a port for charging: the micro usb. When I got mine it took me a minute to realize that, then it hit me that power would really be the only use for that port. So I plug one of my Sammy charging cables into it during use.

Oh, derp. I didn't even see the small port there, looked like a small microSD card slot. Thanks for pointing that out!

Archos Core 70 Mediatek tablet as car install

Hi. I'm swapping the 7" factory flip up sat nav in my Mazda 6 with an Archos Core 70 running Nougat. Here's how it's looking so far.
Now I need to figure out a power scheme. It seems with Mediatek tablets there are problems with accessing the bootloader, specifically that I want to change "fastboot oem off-mode-charge 0" so the tablet boots on usb power. Is that even possible with this tablet?
If not there may be an option to remove the tablet battery and wire the tablet directly to the car battery (5V or 3.7V?), always on, and also have usb power with ignition. Then the tablet should think it's at 100% battery, I could get it to sleep/wake on usb power and maybe have a switch to kill all power if the car's going to be sat for a while (I'll have access to the tablet power button with a toothpick).
What sort of drain might sleep mode be on the car battery?
Would it be bad to cut all power to an Android device while it's in sleep mode?
Thanks for reading.
So not having any more info on changing fastboot settings I've focused on the removing the battery way. I gave the battery terminals 4.5V (nearest I had to the 4.2V I found the battery actually gives on full charge with a multimeter), and it booted, showed 100% battery and recognised a usb power input. So I didn't have to remove the board from the battery like it seems you have to do with the Nexus 7 to get it to read 100% charge. I'll get an adjustable step down converter to get from 12V to 4.2V.

Now I need to wait for the otg usb hub and DAB receiver to turn up and see if I can run DAB while giving charge to the tablet. Then, hopefully I can use the Tasker app to deep sleep/wake on usb power.
I still haven't found an answer to whether I can safely cut all power through a switch for when the car is sat for a prolonged amount of time. I suppose I'll try it and see if it bricks my tablet or not.
Things are looking promising though
