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.

Finally got a pi zero in my hands. Wow, it is small. A picture of pi zero on top of raspberry pi 3. Texas Instruments shift registers so i can talk from Raspberry pi to the nixie tubes with less gpio pins used. Next up will be construction photos and progress. Stay tuned.
