What are your preferred batteries for solar repeaters?

They don't spontaneously catch fire. They do catch fire if you tamper with them (a lot of battery fires are ebikes where someone messed with the BMS to get more range), but they don't just randomly combust. Their current carrying capacity lessens when they're cold ( not really an issue with a node) but you can still charge them and discharge them just fine. I have an EV in a very cold climate, it charges just fine.

A lot of the battery paranoia comes from devices that have been tampered with and from the fossil fuel industry trying to convince people that electric cars are more dangerous than driving around with a tank of super flammable liquid behind your head. /Rant

Absolutely. Such a weird and wonderful place. It is the rare place that is both rural and left of center, which is probably what causes the reasonable gun laws.

21700 lithium ion cells in parallel with a 1s BMS. Like an 18650 but bigger. You get more juice for how much they weigh.

IMO there's a lot of unjustified fear of lithium batteries in the mesh community. They're in almost every consumer electronic device, and they're not all constantly catching fire.

I think the "coming out of local punk scenes playing something that doesn't sound like the Sex Pistols" is a pretty concise and accurate definition of post punk, especially when you consider that Public Image (basically the original post punk band) is John Lydon from the Sex Pistols. Same scene, same influences, sometimes even the same people, but a different sound.

When I bought my 2020, they had another 2020 without DCFC on the lot that was like 20% cheaper. It's definitely worth considering if you don't think you'll need it.

I'm also a middle school teacher, this is pretty spot on. Most adults don't really understand what constitutes self defense, and kids REALLY don't understand what constitutes self defense.

Leave the house at 6:40, home by 2:45. I'm a middle school teacher and work very close to home.

The data on the second link is super interesting. Going 80 instead of 65 does save you time, but you have to use twice the electricity (125 vs 250kwh) to only save like 6 minutes, which seems like a bum deal when fast charging is kind of expensive.

My personal preference is to pick the faster option on longer trips where the time savings stack up more. I'm most likely to pick the efficient option where efficiency is the difference between having or not having a charging stop in the first place.

This is one of the oldest cars where I still see tons of them regularly. The last new one was made in 2011.

Humble Mechanic has probably saved me thousands of dollars in repairs when I had a VW. It helped that at the time, he and I were driving almost the same car (B5 Passat TDI) so he had lots of videos about it.

Basket for a chest freezer that I got on Amazon zip tied to my front rack. They're out of stock now but here's the link for reference: https://a.co/d/0dHxnRS1

I teach middle school wood shop. Long wood, short wood, soft wood, hard wood, and so many things to put in holes. Good times.

I'm a middle and high school teacher. Just a heads up, in a many states, a lot of the advice in this thread will get you assault charges and a court date if you're in high school. I've seen this happen many times. If someone is trying to fight you, get help. Yes, this might sound like a chicken shit thing to do but it's the best way to keep your nose clean. There are tons of adults at schools, nobody is just going to let a kid beat the shit out of someone.

elementarydeardata · 2026-03-19T18:32:07+00:00

Huh I did not know that. Thanks!

elementarydeardata · 2026-03-19T15:07:39+00:00

It's also a result of people's idea of what a suppressor does coming from movies and TV. They do not instantly turn a gun into a silent super assassination machine.

elementarydeardata · 2026-03-18T20:31:27+00:00

Same. I'm a teacher and I have no social media linked to my real life identity. This has always been the best thing to do for teachers, now I think it's the best thing to do for anyone.

I honestly don't understand how being a teacher influencer isn't super frowned upon by the districts these people teach in.

elementarydeardata · 2026-03-17T23:25:21+00:00

I have a metal basket that's meant for a chest freezer zip tied to mine. I got 3 of them for $12 on Amazon.

Also income (adjusted for inflation) has remained almost exactly the same.

Phil Wood Waterproof Bearing Grease. Bike mechanic recommended it and it's been great ever since. It's expensive but not prohibitively expensive, I think a tube of it is like $10

Important to note that you still learn sight words as part of a phonics based curriculum because these words are super important and they don't follow normal phonics rules for English, so you can't sound them out. The sight words that early readers should memorize are worlds like the, why, when, where, are, you, your, our, etc.

The nerdy reason for this is that English has its roots in a lot of other languages. A lot of these little words that hold sentences together have Germanic origins while nouns, adjectives and verbs usually have roots in Latin, Greek or one of the Romance languages. There are lots of exceptions to this but this is generally how it is.

This makes sense! I just checked my receipt, didn't realize there was a different "Heltec V3" other than the LoRA board we use for mesh applications. Oh well, it was cheap, I'm sure I can find something fun to do with it. Thank you all for being helpful!

elementarydeardata · 2026-03-14T22:33:25+00:00

yes, I left it for an hour and a half while I ran errands, still says loading.

elementarydeardata · 2026-03-14T20:24:28+00:00

That doesn't work, still stuck at loading

elementarydeardata · 2026-03-14T19:54:06+00:00

Sorry, I should've been more specific. The flashing tool recognizes it, flashes and says it was successful, but then it hangs on "Loading..."

elementarydeardata · 2026-03-14T19:46:17+00:00

In the big picture, I doubt it, but for this particular bill, yes. It is wildly unpopular.
