Got it running off a 10000 mAh battery bank at 5 vdc. Connected to a tab3 with Windows Remote desktop client for display and keyboard/mouse usage. Using juice ssh app to secure shell also. Pretty neat stuff.

Here it is generating 128 vdc. Lighting a Russian In-2 nixie tube.

Yukon gold from my front yard garden with no pesticides used. Not a huge haul but i only planted one pound of seed potatoes in fabric bags. A little disappointed in the yield but will still be yummy to eat.
