Clock project currently based on ESP32-WROVER-E board with Arduino development environment on PlatformIO.
Display uses small nixie tubes on a home designed circuitboard with SPI control.
-
correct for utc deviation
-
remove "delay" used for timing the clock
-
add loading animation on powerup while waiting for ntp time
-
use OE to even out display segment turn on & off time
-
resynchronize with ntp every set time interval
-
search how to automatically find utc deviation
-
integration with mobile app to connect to wifi
-
connect specialized RTC chip with reserve power
-
connect gps as wifi alternative
-
connect secondary screen
-
connect temperature sensor
-
connect pressure sensor
-
connect humidity sensor
-
lcd display w/ clock settings & internal info on the backside of the clock, a clickable rotating dial for input
-
e-ink display for date display and maybe other info
-
back panel with additional lamps for dots between the numbers
-
PIR/movement sensor to regulate clock brightness
-
light sensor or sun rise/set calculation to determine max screen brightness
