Holy shit this is kind of unsettling. Though I would expect ALL major browsers to reject reading any local files like this… would this kind of thing actually succeed somewhere/somehow?

Before I even clicked the link, I was hoping it would lead to Ben Eater’s video! I’ve gone through many tutorials/guides/videos on the subject of USB, and this video is the only one which really broke it down and presented it in a comprehensible manner.

I highly recommend all of his content if you are interested in electronics at all.
