I'm fascinated by some of the work here

I have a plan in mind I would like to start getting down on paper.. not a design - just a what i want it do do plan

I want my little (maybe big.. but we will say little) cyberdeck to just be my little programming/hacking place. I want to play with my Arduino and sensors and buzzers and maybe have a couple little LCD screens.. some switches.. maybe some radio stuff.. maybe some RFID stuff.. signal generator.. and then be able to do some general programming stuff (python, web deb stuff, maybe some c ?) I don't know the point is general non distracting hacking/ tinker space.

but while I work on a design.. im wondering a couple of things:

1 - Kali vs the Raspberry Pi OS ... or something else? (arduino compatible) - Again this isnt a functional daily driver its a play space.. which would you recommend?

2 - Keyboard options: Since i havent made any designs yet.. im wondering about the raspberry pi kit that comes with the fancy raspberry pi keyboard -vs- my little portable foldy keyboard with a trackpad.
