Sodium batteries are mostly of interest for grid storage or maybe stationary home batteries once they get cheap enough. They are sort of marginal for EV’s but might find a place in some cold weather ones. Having them in a few weird flashlights isn’t going to help ramp up manufacturing volume compared to that. The real demand will come from power utilities buying gigawatts at a time, not a few flashlight nerds.

I remember the Eternalight and it went through a few nicer incarnations over time The designer was a regular on Candlepower Forums. IDK if the company still exists. The product was cool in some ways. IIRC it uses 5mm leds. The first production flashlight with a Luxeon was the Arc LS and I had two of them. I think the semi-custom McLux TK may have been earlier but my memory by now is hazy. I still have mine. Sodium batteries are different. Aside from the very niche advantage in cold weather charging, they are worse in every way than lithium. The main feature that makes them interesting is potentially lower cost per KWH in the long run. That’s great if you want a 100KWH off-grid battery for home, and maybe it can find its way into economy EV’s. But nerdy flashlights, nah, battery costs are not much of an issue already. The bigger light and fancier charging and regulation circuitry negate any advantage. We could already use LFP batteries if we wanted to, but we almost never do.

Only living people can win the prize. If they die between the announcement and the ceremony they still get it posthumously. I’m pretty sure that has happened now and then.

OMG. IV hydration. I wondered why regulate drinking more water, but nooo. Sheesh.

JLR has been paralyzed for the past few weeks due to a cyber attack so the news is that they’re emerging from that.

Interesting though article is from 2016 which is when the scandal happened.

“Let me tell you a secret: chess is the most violent of all sports. I’m a pretty good soccer player and a long-distance swimmer, and recently, I’ve taken up tennis, but I can tell you that there’s no sport as competitive – yes, I’ll say as rough – as chess. The only goal in chess is to prove your superiority over the other guy, and the most important superiority, the most total one, is the superiority of the mind. And there’s no luck involved, no picture card coming up at the right time, no roll of the dice that saves you. It all has to come out of your head. You whip him or he whips you. It’s as simple as that. Or as complicated as that.”

–Garry Kasparov, former world chess champion

So make a lichess.org account and wreak some havoc over the chessboard :).

A lot are trekkers rather than climbers if that helps. Their environmental footprint is much smaller.

Costco has been ok for me.

I haven’t had trouble with the E3A O-ring but for such a minimal setup I’d consider a coin or button cell light, or maybe a 10180 light. Those can be much smaller than an E3A.

I guess see what the E3A page says about the finish these days.

I like the E3A a lot. It’s the smallest 1AAA light that I know of, and the led tint and beam are nice. Unfortunately, mine went poof a while back: https://lemmy.ml/post/22807017

I have not gotten around to making more serious efforts to examine it and haven’t replaced it yet either, but someday. The KC1, meh, it doesn’t excite me that much due to its larger size. The 10440 battery format isn’t so appealing either, imho.

I’ve sometimes thought of getting one of the tiny 10180 lights with a built-in USB charge port. I do also have a few other 1AAA lights kicking around so maybe I’ll dig one out and start using it. The format seems less important now than it once was though.

Added: note that for whatever reason, the E3A in slate blue has a harder anodized finish than the other colors. So I got that one. You might consider doing the same. It was about $1 more, no big deal.

I noticed another review of this light at https://tgreviews.com/2022/07/23/sofirn-d25lr/ that has some useful extra info including a partial teardown photo, and a measurement of the parasitic current at under 1 microamp, very good. I think that review is of an older version of the light, since it has micro USB while mine has USB-C.

My brother had a micro-USB light (now lost) of this series, and it seems to me that the build quality of that light, while not terrible, was worse than the two I have now (H25LR and H25L. So maybe they got better at the time of the switchover. I still highly recommend these lights and don’t really want any more 18650 headlamps unless someone makes a suitable Anduril one.

Yeah I’ve noticed that too and it’s annoying. I just delete the saved text and start again.

Meh. I’m holding out for wretched hive of scum and villainy.

We had that, it was called dmoz.org, looks dead/squatted now.

Cosmological restaurant. It’s at the end of the universe.

Nothing against NPR but I don’t want to spend 22 minutes on an audio. Is there a transcript? Also, confused Amanda Hess, the journalist, with Amanda Hesser, the cookbook author.

If anyone cares, this light was on sale for $10 last week (not any more) and I got one along with an H25L. The TS10 SG is great, smaller than I expected and a terrific value at $10. I will EDC it for a while. For some reason I thought it came with a USB-rechargeable 14500 but it’s the TS10 Max that comes with a USB cell. It’s ok though. I will probably get a D3AA sooner or later but this will do me for now.

I also got an HD10 a while back and I like that a lot too. Unfortunately it’s being discontinued, maybe in favor of the non-Anduril HD12. So we’ll again be in a situation of having no available Anduril headlamps with USB charging. Meh.

If they own houses that is public info.
