[REQ] Build custom lapdock

Hi! It's my first post here!
I was wandering if it's possible to build a custom "lapdock" station.
Basically what do i need is:
- screen hdmi capable
- keyboard
- battery
- touchpad
- eventually speakers
Since a lapdock has only this stuff inside.
Here is a scheme i tought about:

The only thing i dunno is how to make the usb hub to give power to the atrix and to the other devices! I mean it's ok for the electricity, but i dunno if it's correct for data transfert.
About the software, i think that debian could handle all this (speakers via usb, keyboard etc etc.. )
Any suggestion?
sorry for my bad english lol

Are you thinking a stationary dock? Or a mobile dock? From your schematics I am assuming a stationary dock. Either way it would be a great hackaday project.

Actually i was thinking to a mobile one
The schematics works the same, the only thing I assume would change is the dimension of the single parts!

it wont be cheaper than 200 dollars

Sure, but you can add custom parts as a more capable battery, better screen, plug-off BT keyboard etc..

I have been thinking of doing the same type of thing, but my set-up would be stationary. One thing I did think of for myself would be to have a keyboard with integrated touchpad. In the OP's case, it would be one less piece to deal with and make it much more portable.

the more portable you want to make it, the more expensive it will be. and besides, this phone isnt known to run particularly fast on webtop..
lets say you spend 400 dollars... you can pretty much buy a low end laptop that will run way better. the cost to benefit ratio just doesnt seem worth it. not only that, but in the future when new devices come out you might have to scrap this contraption. we don't even know if future devices will have this functionality yet.

Help with LG G3 Homemade heat sink

After seeing this for the Optimus 4X (http://forum.xda-developers.com/optimus-4x-hd/general/guide-homemade-heatsink-easy-to-make-t2971385), I decided to try one for the G3.
I covered most of the back part (except the sd slots, camera, etc.), and although the heat still felt similar (when touching the power/vol. buttons), the games didn't lag/stutter as much (I'm assuming it's cause of thermal throttling).
However, one problem I'm experiencing is the GPS problem. The foil made it impossible to get a GPS lock (and I had to rip the foil out while I was driving and lost, thus no pics ). Furthermore, I tried Googling, but couldn't find information about where the GPS module is located on our phone.
Can someone help with:
(a) Trying it out and confirming that the heat sink really works and isn't just a placebo effect on my side,
(b) Locating the GPS module so we can hopefully work around it?

In regards to b, the GPS is on-die with the CPU, as seen here (In the most obvious place in my opinion, the site of the manufacturer xD)
https://www.qualcomm.com/products/snapdragon/processors/801
Qualcomm decided to put everything into one package so it's not spread throughout the phone and decreases overall size, so yes the GPS is with the CPU and almost everything else
If you watch any teardown video, you will see that the CPU/System die is exactly in the middle of the phone, right behind the lock/unlock and volume rocker. So keeping a nice square cut-out of the aluminum foil should let all the signals pass through, but then you won't have the heat being transferred from the CPU, only from around it so the CPU might still heat up :/
TL;DR: Not really much you can do because the GPS is on the CPU unfortunately :/

That graphic (from the Qualcomm site) is more an infographic than an actual layout of the cpu. Aside from that, it's only the GPS logic circuitry that's on the chip, not the GPS antenna. That graphic shows a camera on chip, too, but we all know the actual camera isn't located on the chip.
What matters for the OP is where the GPS antenna is located. That's shown in the image below, from the Anandtech web site: http://www.anandtech.com/show/8169/the-lg-g3-review/9

Cpu-Z lists soc as Snapdragon 626

All the spec sheets (including the official one) list the phone as having a Snapdragon 625.
Cpu-Z identifies it as a Snapdragon 626 however (see attached pic).
Probably an error with Cpu-Z? What do you think?

They're the same actually. The only difference is that the 626 runs at 2,2ghz while the 625 runs at 2,0ghz.
Since your pic says 2,02ghz it is just the 625. Maybe CPU-z rounds up or so from the 0,02ghz extra listed?

I suggest you to use DevCheck Hardware and System Info https://play.google.com/store/apps/details?id=flar2.devcheck&hl=en
I saw it somewhere on XDA I think. Listed correctly as 625.

Oh! Okay. But did it lag or etc? Because i want to buy Mi A2 lite.

In general, no lag. Fruit Ninja lags but I believe it has something to do with bad optimization in the game itself, because similarly taxing games like Subway Surf and Carmageddon run fine.
Ultimately this is not a phone you would get for its performance though, given that it uses a SOC from 2016. Battery life on the other hand is amazing. At the moment I have 3 hours SOT with 80% battery left (haven't used any games on this charge yet though).

I have a few similar to this little beasty beast, they do the job pretty well,

Space for a SSD up to 1TB and room for another M2:
MediaTek MT7921 Wi-Fi 6 Module:
A closer look:

Down the rabbit warren we go,
Power up lets see what happens.
Does have Windows 11 bonus and the Pro version.
Go thru the OOBE agreeing and disagreeing with MS$ lets see how this works out.
Win11 Pro great to see. Now to uninstall bloat and what we don't need and clean it up a little
Customising and removal of some apps:
I don't like the new Widgets thing waste of screen space
For those stuck in the past, Windows 3.1 was 30years old a day or so ago
Win11 is good,
Like always things new, things move to new location cant find this or that.
And of course compatibility with Older software DOS or WIN7 etc, usually a work around someplace, sometimes we hope.
Lets have a look see:

A few tests to keep us all happy well me anyways
Appears to be working as it should no weird ass stuff.
