redshift
Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night. (by jonls)

The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Advice to an engineering student
Since then I've made lots of things like audio amplifiers and effects, motor controllers, 3d printer controllers and firmware (and subsequently smoothieboard), muscle stimulators, bluetooth LED strip controllers, etc

[Tertiary Level Engineering : PCB Board Design] I've converted the following schematic into board design but I do not know how to go about the layout design. Could someone show me an example PCB layout design preferably on Eagle software? Thank you.
Here's a bluetooth RGB strip controller I made a couple years ago if you want an example.

In your opinion, does a masters in EE or an FE certification hold more weight?
hackaday.com has a zillion links to examples; here's one two three four of mine and I've also got a laundry list of companies I've helped but whose technical details I can't legally publish (note that I've assisted many but not all of the companies in that link)

How do you build circuits?
eg for this project my available inputs were intermittent 12v power, bluetooth, and the current time and location; and the desired output was 3× high current low-side switches that produced 12v RGB PWM corresponding to the colour temperature and brightness of the sky - so we need a bluetooth microcontroller, battery backup to keep time when 12v is absent, some battery management which wanted 5v in, a 12v buck to feed it, some MOSFETs, and redshift or similar code to plug into things.

How can I use an Arduino board to control LEDs so it imitates the sunlight color temperature throughout the day?
Here's one I made earlier although it targets NRF52 and doesn't use Arduino libraries.

Control RGBW led strip with ESP
I've got a similar project here, and most of the complication is for battery management - the actual LED strip drive is even simpler than yours because I chose MOSFETs that work nicely with 3v3 gate voltage :P

Libraries
If you're curious here's a couple of my AVR projects (not using Arduino libraries at all), and here's an NRF52 one

I guess my Sunrise Light project could have been built on Arduino's libraries since an NRF52 core exists, but I didn't do that…

Seeeduino Xiao
For example, this old project of mine uses an NRF52832 (which is substantially similar to the '840, just missing USB) and it offers several services and characteristics including a battery level service, a DFU service, and a custom service for actually controlling it.

Does XFCE have a night light?
FWIW, Linux Mint XFCE comes with Redshift.

If you use your PC for long hours, use Eye Saver app to protect your eyes.
Other options include f.lux and redshift.

I just added redshift as a submodule to handle the GPS location + UTC time to color temperature conversion.

what's the alternative for linux like F.lux for windows for yellow light and brightness for screen?
But I still use redshift and prefer it over f.lux. I am on cell and this is first result so double check https://github.com/jonls/redshift
-
Linux (Debian) equivalent of DimScreen on Windows or MonitorControl on MacOS?
Anyway, for dimming screens with overlays (or gamma alteration), Redshift seems to have a -b option.

How do you even install redshit on windows ? (screen temp program)
The instructions are super confusing to me. Here's the github :https://github.com/jonls/redshift
What are some alternatives?
