I once had a soldering course from a guy that is mainly known for creating a remote that could turn off any TV some years ago, really chill guy but also hillarious that he made a business out of a single gimmicky item like that.
I wouldn't be surprised if he lurks on here, if so, hi!
edit: it's the "TV-B-Gone" by Mitch Altman, who was at the forefront of creating hackerspaces - TIL they weren't as much of a thing in the US until 2008.
