A fun trick is that if you're sure the batteries are in series you can sometimes swap out a pair of AA batteries for a 3.7V 14500 Lithium rechargeable and a fake AA battery (just a wire in an AA-sized plastic shell). Drill a hole in the battery-cover of the device where the 14500's USB port is and now your device is plug-in rechargeable, assuming it can handle 3.7V instead of the normal ~3.1V that comes from a pair o…

I have a headlamp for hiking with a slightly different take on this. It will take 3x ordinary or rechargeable cells, or it will take it's Li-Ion pack that is the same size as the 3 cells side by side. Designed in from the start so there are no dangerous bits. Hiking headlamps are something where you do *not* want to be left with a dead battery!

A headlamp that can run on either AA or 14500 tends to be a better approach than this. Those proprietary batteries are usually pretty expensive compared to a 14500, and three AAAs as spares aren't nearly as convenient as one AA.

There are a handful of these on the market and they're not common in retail stores. I'm fond of the Skilhunt H150.

Cultural differences is an easy sub for racism? Not suggesting bad faith but when it's hard to also take commentary on Asia with good faith here.

I don't know, assuming all cultures should be functionally equivalent seems pretty imperialist to me.

I'm Polish and when I mentioned it I always get commentary about how smart or hard working Polish people are, and usually mention of some mathematician or programmer they knew at some point. And it makes me laugh because if you notice that Polish people are smart or hard working, why don't you give me a quick rundown of who you think is lazy and dumb? Ohhh, that's racist.

How did they fall behind? Didn't they have tabless and 4680 first? Did they lose Talent post 'Nazi' Musk?

a lot of it is probably lack of scale. Tesla is making not that many batteries on the scale of CATL. naziness probably didn't help, nor the fact that Tesla/Musk is fairly famous for working employees way too hard until they burn out.

>a lot of it is probably lack of scale.

Thats what im thinking as well. I was concerned when Straubel announced his departure but after reading multiple sources, it seems like the real reason he left was because he was getting bored and wanted to start something new (battery recycling). My hope is that he put a team there to continue onwards. It didn't seem like anyone was panicking when he announced, sounded like it was in the works for a while.

Cybertruck was supposed to have something like 250k yearly right? Are they even getting 30k yearly?

But still...tabless, structural pack, 4680, dry cell these are all things they had in production first right?

BYD Blade is amazing, but its more of a optimizing a mass market LFP cell no? Whereas I am referring to putting cutting edge tech into production.

So I was talking with the family I mentioned about this issue last night, and he said they got training on it and called it power distance index. Japan and Korea are high index cultures. He mentioned that it's caused airline disasters. It still surprises him sometimes when he encounters it because it's so different from American and automotive engineering culture both.

So I looked, and yeah it's pretty well described:

https://en.wikipedia.org/wiki/Power_distance

https://en.wikipedia.org/wiki/Impact_of_culture_on_aviation_...

So, my question to you is, given that the above is pretty widely recognized, why is it racist to merely describe an experience with this cultural difference?

I don't want to, but I can't stop thinking that DJT might be kind of right on this one. Each of economical blocks in this world such as EU/US, China, or Japan, don't mutually co-depend enough for any foreign currencies like USD or CNY to be single universal representation of values. The current US administration's weird argument is that the USD values exchanged in inter-national trades must be symmetrical, but if you…

>The current US administration's weird argument is that the USD values exchanged in inter-national trades must be symmetrical, In Econ 101 going back to Keynes, if you run a persistent current account surplus, the increased demand for your currency to pay for your exports will strengthen your currency, thus reducing the competiveness of your exports, thus reducing your trade surplus.

But countries don't pay for imports with the currency of the producing nation and get their own currency for their exports. They use the USD for that. Econ 101 doesn't apply when you are an international reserve currency because demand is not exclusively tied to exports.

Increasing FX reserves also increases the national currency's strength because the Central Banks has more reserves to prop up it's value. The opposite is what we call a currency crisis when you run out such reserves and the value of your currency falls.

First off, I love Luma Field. Always incredible to see what's going on inside things. Even just fun to scroll through their Twitter. Second, Anker is one of the few companies I actually have a very high trust for. A few years back I bought a wall charger[0] from them, it has 2 USB-C and a Type A. A month in, one of the Type-C ports wouldn't charge if the other port was being used. If you send a support ticket they an…

Anker is above average, but the bar for average when it comes to Chinese electronics is, "might not burn down your house immediately." For reasons probably bordering on OCD, I watch a LOT of teardown videos of various electronics. And one thing that always strikes me is how a company with a product will routinely and often change what's inside, while the model number and exterior appearance stays the same. For exampl…

Do you have any reccs you enjoy watching? Asking for a friend :)

Acknowledging cultural differences is different from assuming that cultural differences are determined by genetics and not life experiences.

Saying that someone grew up in a culture that values a certain type of academic education and achievement is different than saying they have those characteristics because of their racial genetic heritage.

It's also one thing to be aware of cultural trends and differences when designing multicultural systems to function well. It's another to project cultural trends onto individual people since the variation between people in a culture easily dominates the variation in the averages between cultures.

Of course, nuance like this rarely makes it into common discourse, which often does end up just being racist.

This scrutiny actually makes me more inclined to buy Anker products. There's more trust in a company that will transparently communicate, correct mistakes and raise the safety bar for future products. It also brings to light issues with other manufacturers in the supply chain.

I had one of the affected models. I filled out the recall form yesterday, and they emailed me this morning to let me know the replacement has been sent. They are pretty good about standing behind their products
