what exactly is a cyberdeck ?
that is, what do you want ? its a pretty niche domain, you probably wont find a perfect tutorial. Best to make your own path here.
For some reason N-O-D-E doesn't have his cyberdeck post on it anymore, but here is a repost of it plus a different project: https://www.d10d3.net/copy-of-building-a-cyberdeckhttps://imgur.com/a/h2kR0Gs
There are are a few ways you could go about it. You could hack up an old laptop into a custom frame and install a smaller LCD in place of the old one, or you could do a NODE style Raspberry Pi mod like >>3614
OP here, I'm kinda new and I don't understand too much about it
I have several spare parts, but I have no idea how to build a cyberdeck
lol read the articles I posted
Already did, but i cant afford one raspberry in my country
look I'm not gonna hold your hand through this. There are other single-board computers you can look into – Beaglebone, ODROID, etc.that might be more affordable for you
