PS: foone knows what a chip on board is, right? I'm assuming they just used weird phrasing, but the fact that they called it a "blobbed over IC" kind of threw me off
> They never seem to just use the bluetooth module as the sole microcontroller There's more reasons than just being able to plug a different BT controller (which is great in times of supply chain problems) You're also usually stuck with a different toolchain than you're used to, so you will have to learn all the quirks. And they may not have enough pins or not the right type.. But I get the point. It's kinda funny to…
Lies! You take that back!!
Lithium batteries, even when they don't provide power, slowly lose power. They can also "degrade" when they're not in designated voltage range. This is one reason why most batteries are soldered, because they need to be regulated at all times. So no, you cannot "turn off" a battery. A battery should either provide power, or be plugged to a charger.
This is so obvious from everyday life that someone really ought to write a paper about it and have it published in Nature. Because it will certainly be published. It will probably become the most cited paper of all times, just because of all the pent-up pissed-offery that everyone carries in them, going around in a world where nothing. ever. fucking. works! dammit.
Pfh. Sorry for the vent. This is what impractical design does to people.
Examples lying around in my house: Bathroom scale: lovely it powers up when you tap it, but eats up 2 button cells a year for a few dozen uses a year Kitchen scales, bit more use, at least once a day but again 2 button cells a year electronic caliper: Same, eats up 1 button cell a year, just sitting in my toolbox Strangely enough none of our kids toys with batteries seem to suffer from this problem How much extra cos…
> Kitchen scales, bit more use, at least once a day but again 2 button cells a year I had a kitchen scale that would eat through its battery pretty quickly (within a month) even when not being used. I figured it could be an interesting project to open it up and try to figure out where the stray power draw was happening, but the obviously correct solution was just to leave the battery cover off and pop it in and out f…

It’s strange I have no issue reading posts like these but every time they come up someone complains about the format of twitter and I still have no idea what makes it so difficult for people and I definitely did not grow up with it.
Because it's actively user-hostile. It's not that we can't figure it out, it's that it takes extra effort and creates a problem that shouldn't be there in the first place. If things like ThreadReaderApp or Nitter can present the content in a more accessible & pleasant form, Twitter should be able to do so as well.

Our kitchen scales have a single on button and auto power-off after a minute or so. I discovered completely by accident that holding the power button down for 3-4 seconds powers it off. Nowhere in any of the manuals was this mentioned (I went back and checked)
…And, one should be able to turn of every led even when powered on… At Ikea I almost bought a nice brushed steel extractor hood, except it had this obnoxiously bright blue led on the front. Why? I know when that thing is on without it drawing my attention constantly. Same with my Lenovo X13 gen 2, there is a bright white led next to the power button… just why…???

According to the table in the following Article, lithium batts have the lowest self discharge rate. When you dont have credentials to present please present citations. https://en.m.wikipedia.org/wiki/Self-discharge
I’ve seen several “present credentials” demands here lately. I find it a bit odd.
