Sunrise WakeUp Screen
Simulate sunrise with computer screen.
These days, computer screens are quite abundant, but few have "Wake Up Lights". So, we could use computer screen as a morning light simulator.
Here is a hint, if you're on Linux:
- Check available screens connected:
xrandr -q | grep " connected"
- Set screen brightness:
xrandr --output HDMI-1 --brightness 0.5
Ok, now, let's say you're interested in sleeping at 15:30 UTC, and waking at 0 UTC... You could simply do, something like this in Python:
import os import time device = 'HDMI-1' # Let's say we sleep 1/3 of day, and sun # starts setting 0.5 hr before sleep: sun = {'rise': 1.0, 'set': 2/3 - 0.5/24} fade = 0.025 # amount of day to use for fading lbound = 0.05 # minimum amount of brightness ubound = 1.0 # maximum amount of brightness brange = abs(ubound-lbound) while True: now = (time.time()/86400.) % 1 # night if sun['set'] <= now <= sun['rise']: fadepart = lbound # sunset if sun['set'] <= now <= sun['set']+fade: fadepart = lbound + brange - (now - sun['set'])/fade * brange # day elif sun['rise'] <= now <= sun['set']: fadepart = ubound # sunrise if sun['rise'] <= now <= sun['rise']+fade: fadepart = lbound + (now - sun['rise'])/fade * brange print(fadepart) os.system(f'xrandr --output {device} --brightness {fadepart}') time.sleep(5) # check every 5 secs.
This might actually work...
