Scrolling through TikTok I came across one IrateFrenchFry —the capitalisation is important, they don't rate french fries, though to be fair they're not a french fry either.

If it sees one of those words it activates whatever function I want. "For example, one of my scripts monitors the chat for '!blind', if it reads that word then it activates a servo on my headset that lowers blinders.

" The gaming headset is nothing special: just your run-of-the-mill Logitech G733 , with the obvious exception of the servo powered gizmo on the right ear-cup. "Mechanically the glasses work through a linear actuator that I 3D printed. The blinder (just glasses that I bought and painted) is attached to that linear actuator to allow them to raise and lower.
