First of all, sorry for the wrong "Subject" of the last email! I'm guessing I should switch off "digest mode" on this ML =)

I wanted a small eoma pc card notebook. That is why I obtained the asus 7inch eee pc 4g. When I got the notebook, I took out the mainboard because I wanted to see how much space is in the cabinet.

There's plenty of space, indeed, that's why modders liked it! Those old Intel systems were big and power-hungry - requiring 3 large chips and active cooling, then, slowly but surely, Moore's law caught up and we are where we are, where even our CPU has another CPU inside it =D

As I mentioned, I wanted to convert the notebook to an eoma pc card notebook. Because shipping of the pc card keeps being delayed I have not done more about it. I mentioned the rk3399 mainboard, because it maybe would be an option if the pc card does not get made.

First of all, by the time we get this done, or half-done, some computer cards should be available, at least for us =) Then, using a computer card is clearly a more sustainable and future-proof solution. However, that doesn't even matter for now - let's start with something that will work with both EOMA68 and RK3399 devboard, so we have a backup option!

Yes, but we have to set some references. I am not skilled on electronics. I will have to move on instructions.

That's understandable - I'm willing to spend time walking you through the processes, at least initially =)

Costs may spiral. I am not going to accept that. If I am asked to buy a 100usd device, I will answer no. If I am asked to buy a 50usd device, I will likely answer no.

The mainboard should be the most expensive device of them all, whether it's a computer card or a RK3399 mainboard - this one is not something we can avoid. Other parts shouldn't cost any close to that.

If we in a low priced way can get to use the build in display, that is what we should do.

Absolutely. Sourcing a display that has the same size but different interface, then sourcing cables and making our own adapters could be problematic.

My notebook is an asus 7inch eee pc 4g. I do not know the precise name of the build in display.

They should all be the same - we'll do some testing, too =)

About wifi card, I have small usb ar9271 wifi cards. They work on debian 9 64bit main. Saying the source software is available. We should use an usb ar9271 wifi card.

That's a good option, too. However, using SDIO for WiFi (instead of USB) could help us offload the USB bus, which is good for usability (have you heard all the RPi ramblings about RPi USB? it's not even quarter as bad as they make it sound, and this might actually be worse.) Regardless, it shouldn't be hard to support both options.

About sound. I have an usb soundcard. It works on debian 9 64bit main.

About sdcard reader. I have usb sdcard readers. They work on debian 9 64bit main.

Yep, that's the good part about SD card readers and USB soundcards - they don't usually have many problems, and don't tend to need proprietary firmware.

About storage. My information is, the pc card will have an sdcard port on the pc card for storage.

That SD card slot, as I understand, will be used for the system drive - so, an expansion slot would be useful.

Turning the keyboard into an usb keyboard is an important move. I suggest we make turning the notebook's keyboard into an usb keyboard our first step.

Agreed! My question is - would you be interested in a videocall of some sorts? We could start right off by drawing the PCB, I can show you the basics of KiCad.

About a battery supplying power. I suggest we wait until we have a notebook, which will run on a power supply.

This is, undoubtedly, a good plan for a start, but it's important to remember that we'll eventually need battery power, and plan it in from the beginning - if we don't, that might cause problems down the road. Regardless, I'll take care of this =)

Maybe this modification of a notebook is of interest for other people. We should use this email list.

If nobody else minds, then let's do it!
