Solar is still trying to recover. I did go out and restart it a couple of times, as I did not want to wait a day. I did not bring it in to charge, I want to know if keeping the Raspberry Pi shutdown allows the battery to get a full charge again. I did measure the voltage at 3.2 volts, which is low but not the 2.5 volts the under-voltage protection kicks in at. I did notice today that it pinged the server and shutdown after receiving its command for the day.
I did learn something today, that I already knew but did not know the extent of. I have MariaDB database and Apache running on a Raspberry Pi 3 model B+ with 1gb of RAM. I was running the full 32-bit version of Raspberry Pi with GUI enabled and running htop its memory usage was peeked. I decided to try turning off the GUI and see what happens. After a few hours, I am still at only 1/2 of the RAM consumed. I already knew this was the case, but I did not realize that the GUI environment consumed 1/2 the memory.
The more you know.
Side notes:
- I need to get a voltage meter working on the rover.
- I need to get the current status of the rover on Mission Control’s screen.
