Debate: salvaged solar cells from yard lights vs buying new panels for a phone charger build?

Hang on a sec, your buddy's got a point about speed but the math's a little off. Those garden light cells are usually around 0.5 watts each, so three of them give you maybe 1.5 watts max. A cheap 5 watt panel from Amazon can actually pump out closer to 1 amp in full sun, which is roughly 5 watts. So yeah, it's more than twice as fast, it's like three or four times faster. But that $12 difference means a lot if your whole budget is like $15 for a fun experiment. You gotta ask yourself if saving a few bucks is worth watching your phone charge at a crawl while the sun's out.

Why I stopped doubting the moon landing footage grain issue

I saw a similar breakdown from a film archivist on YouTube, he went frame by frame with the Kodak datasheets and it really clicked for me how the grain works with that specific film stock. Did you check out that NASA tech talk, was it the one with the engineer explaining the ASA ratings?

Used to just dump all my concrete tools in a bucket of water...

Good heavens, old diesel as in the actual used stuff from your crankcase? That sounds like a disaster waiting to happen.

Watch out for self-tapping screws on steel studs

Honestly, is a stripped screw really that big of a deal? People act like it ruined their whole weekend or something. I get that it's annoying, but you just grab a different bit or use a rubber band and move on with your life. Half the time it's user error anyway, people just forcing a Phillips head into a slot that clearly wants a square drive. It's not like the screw is personally out to get you.
