(4/23/21) Progress:  64,8%      Hardware: v9       Code: v9.8

Update: Time for some pictures of Hardware implementation and UI progress:

Prototype v9
Layout of Battery pack, power & charging boards inside the Thermal Duct, that the empty battery slot creates.  Components are mounted on Aluminium heatsink that goes from top to bottom with maximum exposed surfaces to the Airflow.  There are two levels of PCBs in this design. 3x 2S 2A Chargers(?), 4x 3A voltage buck converters, INA219 + INA260, 400w PWM Controller, 2S 20A Protection/Balance Board. Hoping Air will still flow ok.  Also still figuring out the power path for charging.
Loading Screen
Loading Screen (random selection of 12 different screens), shows loading errors and reset reason
Progress with the UI: It's still not very beautiful, but already does almost everything that was planned.

Home Screen displays most important Data Points
Home Screen displays most important Sensor Data.  The whole System has a warning Screen for critical Over/Under - Temperature, Voltage, Current, Wetness values and sets everything into Low Power / deepSleep modes. Phone-like Status Bar for SD card, Logging, Fan, WiFi, Battery, FPS, Lamp, time since reboot. Small 0.49" Screen cycles through sensor values, shows alarms and indicates charging.

Heart Rate & Blood Oxygen Monitor
Heart Rate & Blood Oxygen Monitor.  Diffuse LED swells and beeper indicates Heartbeat as well Small 0.49" Screen shows Heart Rate BPM
Data Graphs (CO2, VOC, Voltage, Amps, Fan State, Temp, Humid)
Data Graphs (CO2, VOC, Voltage, Amps, Fan State, Temp, Humid) (CCS811 is freaking out here because of the voltage drops)  Small 0.49" Screen cycles through sensor values, shows alarms and indicates charging.
System Status, WiFi, Debug
System Status, WiFi, Debug (re-initializes sensors in case of error)
CO2 Info screen
CO2 Info screen.   Small 0.49" Screen shows CO2.

there is also a total VOC screen and a Thermal Cam screen, but im still waiting for the AMG8833.
