  • Ah yes, the classic child-abuser-apologist line that every “christian” brings out when confronted about the abuse of their revered leaders that they absolutely refuse to condemn before they go back to church to give money directly to the abusers every week.

    Do you love Jesus or have convinced yourself that you love him because you are so afraid of hell? Very Stockholm syndrome-esque. Take kids during their developmental years and tell them that “people” go to hell and are tortured forever unless they love Jesus and follow sky-daddy’s rules (and by extension, the rules of the church). Then they are told that over and over until they are brought to a special ceremony to declare their love.

    Or I guess you have never once been to church and never a single time been told that people go to hell if they don’t love Jesus and accept him into their hearts? I guess you just read the entire bible without any external influence at all and converted after your brain was fully developed after 25 or so, again, with nobody telling you about it. But I guess when you lie, you can just ask Daddy for forgiveness and you get off with no consequences! Tons of harm, no foul.

    Either way, I guess I am glad because it is the only thing stopping you from rampaging around murdering, raping people and animals, stealing, torturing, maiming, abusing, and whatever else you apparently so strongly desire to do.


  • You said it right there in your comment.

    Sleep mode, (and other effectively off modes) where it is functionally useless, it can do.

    MSP430 can do 140uA/MHz. That is ~7 times the power that this application supplies, and that is not counting any single other chip quiescent current or chip that actively provides useful data. You would have to have a battery anyway or a big cap to provide the needed current for on-states. Or you could run it extremely low frequencies like you said, but those tend to not scale linearly at all with per MHz power ratings. Quiescent currents tend to catch up fast at that scale. I would be extremely doubtful that 150kHz would scale perfectly and wouldn’t have already exponentially decayed to around its lowest possible on-state consumption for the chip. I would definitely have to see tests on that.

    The smallest of batteries like the VARTA tiny cells in TWS’s are infinitely more useful and practical and it would take this application months to fill a single cell, discounting all losses.



  • I don’t think people realize how extremely little 50uW is.

    For a standard 3.3V microcontroller assuming a 95% efficient voltage regulator will be a current of 14.4uA. Just having the HSI master clock enabled on one of the low power STML0 chips is 15uA. This will literally only the clock. That is 0 sensors, 0 communication, 0 IO, nothing useful at all. For reference, reading SPO2 with a very efficient maxm86161 takes 10uA by itself in ultra low power mode with low accuracy and not counting the max leakage current of 1uA. For full operation, you need about 1000x-10000x that amount for short bursts.

    “Oh but it can cHaRgE tHe BaTtErY”

    Let’s say the device has a standard 100mAh battery (apple watch had a 228mAh or more). At 100% efficiency with absolutely not one millijoule being used by any other electronics (which would never ever happen, it would at the very least need a boost converter), it would take around 277 days to charge up that tiny tiny battery.

    Let’s take another example of an even smaller battery. To charge one side of the airpods 3rd gen (0.133Wh battery), it would take 110 days per ear

    This is one of those free “energy harvesting” fad BS based in nothing but wishing and marketing. It is an interesting learning project for wireless antenna beginners, but that is the extent.



  • With electronics, that is only the tip of the iceburg before you get into trinocular microscopes which the absolute cheapest are almost 300€ nowadays 😉 then assembled PCB prototypes where every iteration can be 200-500€ depending on size. Or you could get into spending hundreds on hotplates and reflow ovens to do it yourself.

    But wouldn’t it be faster and cheaper in the long run to be able to fabricate the simple PCBs yourself? There goes 1000€ on a small CNC 😂 rabbit hole goes deeeeep.


  • Electronics projects mostly.

    Mostly smart home PCBs and interconnect boards and 3D modelled housings. Examples:

    • esp32-C3 dumb doorbell (just a doorbell that sends an MQTT message and sleeps the rest of the time). It works fatastic except that my Proximus ISP modem/router completely fucked up and so the network is no longer usable and I had to set it in bridge mode to a router it can’t reach. I want to release it, but haven’t had the time to water - resistance test it or make assembly instructions
    • esp32-S3 voice assistant satellite attached to an IR blaster, I2S mic, and PCM5102 to control and send audio to my old Yamaha RX-496RDS to control it via IR and can play audio (local or Spotify) via music assistant. Pretty much an Alexa echo attached to my speaker system. PCB link which I am planning on releasing.
    • My unfinished Flight Stick with custom electronics, fully custom 3D printable housing, etc… It is almost done, but needs like 2 more small iterations, but we moved and started doing a full-strip renovation, so my 3D printer is no longer set up because it is too dusty inside, and I don’t want to spend another $100 doing a PCB test iteration to use a better ADC with less components. Eventually as firmware practice, I want to rewrite the firmware in Rust or something. I also just looked at the Repo and the quick logo I drew up has been modified somehow without any commit. I know for a fact it was correct before. Very weird.

    I also have tons of new project ideas that I don’t have time for.

    My other hobbies

    • weightlifting, again completely dropped off due to every free moment renovating

    • Running a home server with replacement services for everything I need

    • Running (my motivation has been 0 recently…)

    • cooking. I try to do a few new recipes per month

    • gardening. With the renovation, I just grew a few courgettes, tomatoes, and squash this year

    • video games (more of a de-stresser nowadays than a hobby, most recently casual rocket league with friends is fun, hadn’t played since 2018 or so)





  • It’s interesting the difference in what people think a collapsed civilization will look like.

    Some people think we will “return to monke” where wilderness survival skills will be essential and people who have them will be the “main characters.” That would probably be the easier and better future.

    The more likely option will be technofeudalism where rich people have small, brutal armies and control localized power grids, farming operations, and politics with tech as mass migrations happen and wildlife becomes all but extinct outside of human cultivation. Survival skills won’t matter when all land and food scarcity is controlled by a rich few with absolute control. The average survivalist will be wiped out with the first natural disaster or by the feudal lords with drones. Return to nature might only come after 50 years when chip supplies and power grids have dried up and fallen apart, but it would just as likely be mad-max as oil could likely still be used.

    Who knows. Fascism might take over with how it is going now and solve the climate crisis with mass genocide and forcing green energy for all we know.


  • The thing about meshtastic is the walking distance range and limitation to text messages.

    Though I don’t know if it is possible to integrate a LoRAWAN concentrator with a nice collinear J-pole antenna to mount on the top of your house to move to a double digit range where it could be useful as a neighborhood mesh with multiple channels. (With the added benefit of using lorawan devices like pet trackers and things).

    Still Lora smart (but local) home agriculture, water collection, etc… Is a really cool technology for large properties.



  • I still have a 5 year old Jabra Elite Active 65t that is still trucking. I had a few glitches starting a year ago like the right earbud dropping in volume or it being stuck in a hung mode where they had to be completely depleted over a few weeks to reset them, they wouldn’t even charge.

    However, they still work fine and are super convenient with hear-through for office work compared to wired IEMs way better for all fitness activities too, just not as good for really listening to music.

    Battery life is still 3-4 hours after 5 years not including the case recharge (the case battery has degraded significantly more than the earbuds themselves, probably due to the high quality VARTA cells in the earbuds)

    I am going to wear them into the ground, but jabra is doing a stock sellout before their new version of buds come out, so I bought the €140 Jabra Elite 4s for €60 for when these bite the dust, but they seem to be going strong still.



  • I mean China definitely does it.

    Tibeten “re-education” anyone? They stole the playbook for Tibet right from america dealing with native Americans, but with a little less outright killing. Uyghurs is less language genocide and more actual genocide and concentration/slave camps.

    America did it and does it with native americans. Americans did it with literally every single group that came into the country with their whole “English isn’t our official language but you better speak English or be ostracized” through its history.

    Literally every nation has tried at one point.

    I am pretty sure language erasure is not “a form of genocide”, but “a component of recognizing genocide” or something that states thag commit genocide commonly do. I have looked at a bunch of definitions and genocide definition seems to always involve actually killing people:

    any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:

    (a) Killing members of the group;
    (b) Causing serious bodily or mental harm to members of the group;
    (c) Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;
    (d) Imposing measures intended to prevent births within the group;
    (e) Forcibly transferring children of the group to another group.[3]
    

    My point was that every nation does it simply because of nationalism and ease of administration. Governments already run bad enough without having to keep 25 running translations of every document.



  • L O L “doing something different”

    Epic tried to pull an Amazon.

    Get VC money and chinese money and subsidize and undercut competition using anticompetitive practices to gain market share before the rug pull where they jack up their margins to the industry standard. (Everyone uses 30%, even brick and mortars except humble which is 25)

    The difference is Amazon actually made a good software experience in the beginning few years and Epic spent literal years with very few feature updates and whining and burning money suing about “unfair market practices” when they were the only ones actually engaging in anti-consumer practices like paying off developers to be Epic-exclusive and buying developers and removing their games from steam. The other “different” thing that they did I guess is their CEO is an outspoken objective asshole.

    They never got to the rug pull part because their actual software sucked balls and they refused to improve it so much so that someone else actually made a better launcher than them for their own products…
