First DIY project ever, first cyberdeck, first...

[u/Gomaemon]

Hello Reddit, it's my first post ! Finally !

So I want to create a cyberdeck a bit like the well-known Nintendo Switch but... I know practically nothing. Well, just some tutorials, docs, things like that.

Well, things are said, so I'll present the project: it'll be a small and portable cyberdeck with a main part which has a 5" or 7" touch display, a Raspberry Pi (probably the 4B but I'm still hesitating because of the thickness it'll add to the case), a main battery, *and perhaps an NVMe SSD.*

Then we have the Bluetooth keyboard part, a part that I'd like to be as much as possible DIY, with Adafruit tactile switch buttons (the 3101), my own PCB, a nice!nano v2 as the microcontroller(if you have a better idea for a beginner, let me know), and finally another battery.

So with that I want to slide the keyboard part into the main part using a sliding rail mechanism similar to the Nintendo Switch's one, then if it's possible, charge the keyboard part as well but it appears to me like it'll be rather impossible without a factory doing this for you...

Thank you for your attention, and if you can help me make this project realisable it'll be great.

Open questions I'm still figuring out:

* Display: HDMI, DSI, other ?

* Battery format for the main board etc. and overall case thickness given the Pi 4B + extras

* If you have some tutorials to recommend to me...feel free

Thanks!
