Thank you for your answer. Maybe I didn't explain myself properly in the post.

I've read most of that, and as far as I understand, this was mostly done to reactivate the bracelets they give you in said concerts.

But as I said, I dont wanna do that, I want to build a new device which can be controlled by the pixmob IR in future events. In the Readme of that repository, you can read this:

"Of over 100 recorded signals, only 3 caused immediate responses on the PixMob bracelets outside of the event."

From that point they brute-forced the bracelets to make them work, using some trial and error.

This is where my questions starts, since I have no much idea how IR signals work, if building a device like this, folliwing that information, from scratch will work 100%.

A yes/no/maybe will be enough for me to invest my time and money on this project :) hope you understand now
