This guy always has an unreal amount of engineering lift for hobby videos. A treat to watch every time.

JKCalhoun•1h ago

Yeah, a YouTube treasure. For anyone new to his channel, you have a back log of amazing experiments to binge on.

I believe he works at Alphabet (tangent?)—somewhere in the Bay Area.

quux•31m ago

IIRC he works (worked) for Verily, and previously was at Valve working on their VR hardware. He's also mentioned having a business pre-Valve that made MRI safe controllers for users to interact with computers while inside an MRI machine.

What a 10x engineer does in his free time

mikkupikku•2h ago

Pity it won't work for chocolate holograms.

alganet•1h ago

Why not?

ThrowawayTestr•39m ago

Because chocolate doesn't form oxides

ggm-at-algebras•15m ago

You need a mechanism which forms interference fringes. Chocolate blooms, so you might be able to etch the bloom.

Otherwise, it's skim an edible oxide layer over the chocolate to etch.

alganet•14m ago

I thought the oxides were just for color variation. Maybe I misunderstood that part.

Could this be used to make a diffraction grating on PMMA?
