Working Prototypes

Inside Station plugged into the computer.

Outside on the front porch running on battery.. Under cover so the rain doesn't get to it too much.  Two days on the Li-ion battery and it still shows ~4 volts. Almost fully charged.

Since the radio is using SPI, I set the display up as I2C, I follow the two rules of micro controllers - Unused memory is wasted memory, and Unused pins are wasted pins.

The data is being sent to - I am going to try and let it run for a few days and not monkey with the code too much.  I have code to measure the battery voltage - but I am going to resist it for the time being, and just let it run...
