Today I finished setting up this account. 2 years of progress. Also I got a pi touch screen as a present with a raspi3. Got it to work by upgrading the matchbox keyboard software(This would of been really helpful in the guide), I'm very happy with it so far, Runs on a cellphone battery bank with capacity of 268*10^2 mAh, 5volt at a max of 2.4 amps each or 5.5 max total. If you want it, I really like it.
