Is there a manual somewhere how to set up Nxt on a cubietruck?
RaspNXT runs "out of box" on the cubie. Just install and update with latest NXT version. (I haven't come around to have it auto-update itself yet)
BTW, behold here a quick shot of my solar cubie


I'll follow up with more info soon

That's fantastic, great Job!
Now make a manual for this on Nxt Wiki and put in some nice pictures.
