One of the first thing I tried was nkro on synergy, I'm very surprised at how versatile that software is, made a donation right away, talent has to be rewarded
...
I'm not sure how practical this setup may be and what problems/costs will arise along the way, but i think it will be worth exploring no matter what the results, journey/destination type thing...
I've been looking at some small monitors for RPi and there is a decent amount of those available, i won't need it to be wireless, something compact enough to not clutter the setup, 3.5/5" , ideally i would love to just pull apart one of my old droid smartphones
but from what i read it's kind of a pain in the ass to find the documentation on pinout etc... another option is to use one of those 'rear-view'
car monitors this way the s-video is utilized and you don't sacrifice a usb port and maybe use it for a
touchscreen overlay... or
vnc into 'droid'... So there are many options for RPi monitor...
As far as the 'Main' monitor being 'wireless' (aside from powercord), I've been looking into these
kits or similar. They seem to be pretty quick. Need to find someone who has one to get a better understanding of limitations...
One thing you have touched on that is the next thing i will be researching is the 'power' side of this setup... While i don't mind a straight, extension cord , I think there has to be an elegant solution to power the 'RPi,USB HUB, 3.5/5" MONITOR' probably too much for solar
but a good battery system should handle the load.
As far as running cables for everything... trust me
i don't mind the clutter and rolls of wire
but i think i need to explore this first, tired of nagging
