I bought a set of 5 Attiny85 micro controllers and used the Arduino IDE to dump a sketch onto them that makes them into mouse jigglers..
Basically they plug into a USB A port and emulate a mouse. It moves the pointer back and forth one pixel between every 10 and 30 seconds randomly.
The movement is nearly undetectable to the naked eye, but it will keep a computer from going into suspend or locking if you give it a lengthy job to do.
It's not my code.
I found it here:

I got the micro controllers on Amazon here: https://www.amazon.com/dp/B0836WXQQR?th=1 I'm sure you could get them somewhere else cheaper, but I wanted them fast in this case. # microcontroller #attiny85

Also, yes, I know that you can kind of do something similar with caffeine / caffeinate, (https://linuxvox.com/blog/caffeinate-linux/) but that wasn't working reliably in the latest version of PopOS / Cosmic, so I resorted to using hardware, which has been 100% effective.

@paradroyd@mastodon.sdf.org also a good way to get you fired. So dont use it for work.
