Don't let your computer go to sleep, like, ever.
By Landry COLLET.
On some machines, you don't have the possibility to disable the automatic screen lock, and it's set aggressively low by your IT admin. Most of the time, it's for your own good, especially on a laptop. But if you work from home and have a test running that you need to monitor, or deep in a conf call, you might end up losing 20 minutes a day typing that annoying 25-character password to unlock the screen.
SleepDeprivator is a tiny USB device, made of a Trinket Pro, that will automatically send an invisible keyboard input periodically, mimicking a keyboard press that postpones the computer screen lock.
The firmware, as is, sends a press on the left control key every 30 seconds. That's nice for a Mac, but for your PC, you might want to change it to something else, unless you never use the Q key (:

-
Find a Trinket Pro board: https://www.adafruit.com/product/2000 (also available in every electronic shop).
-
Make sure your Arduino IDE handles the Adafruit Trinket boards. If not, follow those steps: https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/arduino-ide-setup
-
Make sure you have the Adafruit Trinket Pro Keyboard library installed. If not, download it here and install it: https://learn.adafruit.com/pro-trinket-keyboard/library Refer to that guide if you don't know how to install a library: https://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use/arduino-libraries
-
Open the Arduino project in
sleep-deprivator.ino. Build and send it to the Arduino Trinket Pro. -
Optional: you can connect a switch between ground and pin 4. Pulling that pin low will disable the virtual keybaord.
-
Print the case for the Trinket Pro with a 3D printer, and install the board in.
Plug it to your USB hub that stays on your desk, and your computer will never go to sleep anymore as long as it's connected to it.
