Ten LSM6DSV cheesecake SlimeVR trackers assembled! Tomorrow is firmware and software time--hopefully all goes well.

Key thing I've learned so far: never select economy assembly from JLCPCB. Of 5 charging boards, I've got 2 that are good.

Why AI Can Push You to Make the Wrong Decision at Work

Automation bias is the tendency to be less vigilant when a process is automated. But can we effectively check ourselves against AI before making a wrong decision?

I saw this screenshot posted on a Star Trek Discord server today and really liked it. A little digging turned up the original post and reply on Tumblr: https://roach-works.tumblr.com/post/739090278705774592/it-used-to-bother-me-that-all-the-art-in-star-trek

@[email protected] right. there are three main types of capacitors used in consumer electronics: aluminium electrolytics (and their fancy polymer cousins), solid polymer (tantalum), and ceramic (more specifically multi-layer ceramic, or MLCC). the aluminium electrolytics are the bigbois, lots of capacitance. good for bulk energy storage. bad at higher frequency stuff. the fancy alupoly ones are for higher ripple currents. tantalum are a middle ground. low voltage, high capacitance density.

Convo between me and my Nigerian American dad a few years ago:

๐Ÿง”๐Ÿฟโ€โ™‚๏ธHey Pops! How much do you know about cryptocurrency?

๐Ÿ‘ด๐Ÿฟ It sounds like scams. Is it scams?

๐Ÿง”๐Ÿฟโ€โ™‚๏ธOK, so you know about crypto. Anyway, most countries have banned crypto mining, because it taxes energy grids. Texas' grid is already fragile, but your governor is inviting more crypto --

๐Ÿ‘ด๐ŸฟSo we should buy a generator? Like in Nigeria?

๐Ÿง”๐Ÿฟโ€โ™‚๏ธOr solar. Because crypto --

๐Ÿ‘ด๐Ÿฟ Why are you making the story so long? Crypto is scams. Buy generator.
