Having done a lot of research into this, the state of things sucks right now. The current open-source options have very bad tracking (like, just a very rough estimate) and are much more focused on smart-watch interfaces, which I get because having made a smart watch development board myself, PPG AFEs are a black hole of NDA-riddled bullshit, manufacturer lies and bad documentation, and no support (looking at you Analog Devices). ZSWatch is the most promising open source project using the best openly - available sensor set with the potential to hit 80% heart rate accuracy, but that is still years away.

Honestly for half-good tracking, your best bet js Gadgetbridge + a proprietary smart device that is entire locally supported.

For example, the 100€ Amazfit Helio Strap (no screen) has great heart rate tracking and better than average sleep tracking (old strap style or bicep strap) and you can run it once in the official app to update firmware and extract the encryption keys, then from then on run it completely locally on gadgetbridge and uninstall the official app completely.

Letting perfect be the enemy of good enough sadly leads to almost useless tracking data in the open source wearables world. For now at least. Making wearables is insanely expensive and to get the best sensors you need NDAs and quantities >10k per year which is unobtainable for community open source projects right now, and you need massive amounts of user data to build good algorithms to analyze the data from the sensors.

I thought meshcore.wasn’t focused on positioning systems and that meshtastic is more suited for that application?

Cool project! Epaper is awesome and crazy microfluidic tech.

The M5stack M5paperS3 is 60€ (56,70€ at Tinytronics in NL) and is auch more readable size, integrated battery, 4.7inches. More like an older smartphone screen and have very fast refreshing.

Nicco loves Linux (KDE contributor and a sort of blogger) made a whole to-do app/system that runs on it so it is temporarily out of stock at Tinytronics, but I think the problem with the small screen is having to refresh >3x as much to read the same amount killing battery life on an already smaller battery.

I think personally I would have trouble either with font size, or only being able to read a few sentences before scrolling.

But zeeschildpad doesn’t include things like box turtles that live near bodies of water but not all the time, right? I guess here in Belgium we just use “schildpad” for everything.

It also sounds cooler to translate it to shield-toad lol

And every year new open mass surveillance worse than the UK and US attempts to be passed and barely fails.

GDPR also doesn’t mean shit if it is barely enforced against large companies or the fines aren’t revenue-proportional… Then it is just a cost of doing business.

No idea, but it wouldn’t be something I was willing to stake precious documents on.

I think SimpleX is the only one that fits that.

Sadly, the developers started crypto NFTish integrations last year. It is still too early to see if their use of it will end up being good or a slippery slope into crypto scams.

How useful is it if the data or equations aren’t good?

The VO2max estimation they use is based on heart rate vs Pace data correlation. It is directly correlated to heart rate sensor accuracy. As QualifiedScientist on YouTube has found with his statistical comparison testing vs a polar H10 chest strap, many, MANY watches are <90% accurate with heart rate. Fitbit also has a ton of barely-accurate devices.

The Garmin algorithm has actually been studied multiple times and has around 5-7% error

Apparently fitbit VO2max hasn’t been studied, but anecdotal data by people doing a lab test to compare give quite bad results. 4-49% error! That is pretty much useless. There are also claims that fitbit uses BMI to estimate it which adds even more error.

Fitbit’a implementation seems similar to the bullshit recovery indexes, stress levels, and 2-4 degrees of abstraction metrics…

FYI, there is like a 99% chance that reddit doesn’t actually delete your data if you delete your account, even the comment scramblers only help vs bot scraping. Reddit likely has comment history in their databases.

To charge faster, yes.

Here in the EU, 11kW home chargers are very common. Especially because three-phase power is common.

I also did that in university. I somewhat recently learned that there are many different fire ratings. These small ones are usually rated for lower temperature “fires” for <30 minutes. In a real-life fire scenario, only 30 minutes under heat is almost never going to be the case, it would likely be 90 minutes or something and higher temperature on the higher floors like an apartment.

If you are looking for fireproof safes, these types technically don’t let the flame in, but they get so hot that the documents turn to dust apparently. You generally need a lot bigger safe to be able to be thick enough to disperse heat

For theft, you also need a super heavy or bolted down safe or they will just take the whole safe.

Safes Re expensive stuff, sadly.

They should be the default for solar installations and grid-level storage, but are too new.

They can also replace lead-acid batteries for many applications.

Lithium will still rule microelectronics and wearables, but all lower density stuff should switch to sodium.

That being said, for cold environments like Scandinavia and the US Midwest & canada, sodium ion works better in both cold and heat swings than Lithium variants that it might be worth the tradeoff in capacity because in the long cold months, the reduced capacity and performance of lithium chemistries would completely close the gap anyways.

Forensic pathology is something that very very few people enjoy also, but is very needed.

People love intellectual jobs, creative jobs, and some public service jobs. It is much much harder to find people to do body-destroying terrible-condition manual labor jobs. Ideally those are the jobs to be replaces, but of course capitalists want to replace the former category of jobs because those cut into their profits more.

It isn’t open source hardware. It is license-free IC architecture.

The hardware will still be closed source in 99% of cases, but the architecture is “open” and can be used without licensing, lowering the barrier to entry for making CPUs (it is still very high as volume is the name of the game at fans. Tapeouts for testing a design can be €1k on the very cheap end, often more like 10K+)

A step in the right direction for sure, but open source IC designs are still quite limited.

Like the other person said, it can still be very nice and useful!

However, modern (even cheap) DMMs have some quality of life or useful features like auto ranging, diode measurement, capacitor measurement, max/avg/min functions, duty cycle, etc… Like the standard low budget ANENG AN8008. And this one is certainly better quality than the cheap stuff.

Though the continuity sensor for that meter being able to select sensitivity levels is quite nice. Most multimeter’s simply use “banana plugs” so you can’t go wrong and can always use standard lab wires (that are readily available)…

It often gives incorrect maps simply because of update schedule and them encouraging not reporting construction <3 months or whatever.

We have construction all over in Belgium and tons of detours such that it makes open street map pretty much unusable as it will just incessantly reroute you to a blocked path even after you are well on a different route.

Because America runs off of shirking responsibility to blame someone else: using precedents as loopholes to not have to argue a case.

1 state does it: 25 others follow suit immediately and it gets insta-passed because “there is a precedent”. See: flock cameras, Bibles in schools, book banning, abortion banning, sweeping climate protection rollbacks, etc… Once one does it, the rest of the cowards use it as a shield like children: “B-B-But theeey doooo iiiit!”

I dunno man, my farmer works from 6h to 23h with barely a break in between, only eats when he absolutely needs to or is going to fight ghosts alone to get sprinklers to ease the work just a little, and maybe has a couple days of talking to people or going to the arcade per season lol.

Relaxing for the player, maybe not for the farmer themselves.
