Build my own laptop/tablet

[Steven Smith]

So I've commited myself to build my own tablet or laptop. I've already purchased a LattePanda, despite the slightly high price tag.

At first I'm going to be using it as a super portable desktop and just using the hdmi on the TV's in hotels.

As time goes on though, first will be a m.2 nvme ssd, then I was thinking of using

to add a gtx 1050ti, to the m.2 E key (even though I know its only 2 pcie lanes) and a 10 inch touch ISP display that has compatible eDP 30pin and captive touch. 

 

As this is my first time making anything like this I wanted to ask if anyone here can see an issue with how I imagine this working out. I have built every desktop I have ever owned but this is going to take me to the next level. There are some terms I am not quite familiar with. For example, what is the name of the correct voltage regulator to maintain a steady 12v for both the LattePanda and eGPU slot?  And now looking at my "back of the napkin" drawing I'm sure the output of the batteries need to be separated from the input of the balance charger.

@iamdarkyoshi tried to do something like this a few years ago, not sure what happened with it

Alright I have the panda and a gtx1050ti and I got a cheap m.2 to pcie x4 adapter for testing and all is good so far. Now to find a donor screen and decide if I want to use the E key or just go with a usb 3.0 ssd.

 

I was thinking about a power supply like this

and just using one 12v power supply from

I don't want to have to run multiple power supplies for the different components or have to tote around a full size atx power supply.
