Handheld laser

This guy is annoying as hell, but he builds an impressively powerful handheld laser.

Just ff to about 9:00 and watch him burn stuff.

While my locked-down "normal" self is going 'whoa, that's pretty cool', my professional safety-engineer self is recoiling in horror.

That is really bloody dangerous.

It's nice to see Shamwow Vince applying himself a little more these days.

Using the max input power this guy calculated for his build, a new iPhone 11 battery (fully charged) can run that handheld laser thingie for over 50 minutes.

An electrical shorting of a fully charged iPhone 11 can potentially discharge that much energy in a fraction of a second — catastrophic if something like this were to happen in someone’s pocket.
