I picked up some Pi Zeroes at Micro Center on the 14th Pi Day. They were having a sale on them for $3.14, so I picked up two Zero Ws and 1 Zero.
I ran my AA NiHh battery test on the Raspberry Pi Zero without WiFi. Nothing plugged in but the Pi, and its SD card running my Python Script. It lasted 28 hours!
Now to try the all-day/night test on the Raspberry Pi Zero W. connected to four batteries and two solar panels.
I will use a simple circuit with a diode for my first test.
Here goes nothing.
