  • It’s BLE - Bluetooth Low Energy.

    Basically devices with BLE can listen for a wake-up command and turn on, similar to the “magic packet” of wake on Ethernet.

    Super convenient for “find my device” applications, also nice to be able to connect and activate the device without having to press a power button like a peasant.

    It also means that most devices with BLE end up flat within a month. I had a speaker with BLE and had to deliberately download a much older version of the Android partner app to turn it off, as they dropped the option to do so in later versions for “convenience”. With BLE on it would be flat in about 6 weeks regardless of whether I’d used it or not , which really ruined ad-hoc usage for me.






  • This kind of reliability is huge for prosthetic limbs, fitness trackers, and robotic arms, where precision and durability are non-negotiable.

    Thanks, AI slop! Sensors that have been durability tested for a few hundred cycles will be perfect for prosthetic devices that can do that in half a day of office work, or fitness trackers that can do that in five minutes, or in robotic arms that can perform that kind of movement in 60 seconds! I’m going to use them in my next safety critical robotics project for sure!




    1. Replace CMOS battery.
    2. Get small UPS.
    3. Discover that small UPS’s fail regularly, usually with cooked batteries.
    4. Add maintenance routine for UPS battery.
    5. Begin to wonder if this is really worth it when the rest of the house has no power during an outage.
    6. Get small generator.
    7. Discover that small generators also need maintenance and exercise.
    8. Decide to get a whole house battery backup a-la Tesla Powerwall topped off by solar and a dedicated generator.
    9. Spend 15 years paying this off while wondering if the payback was really worth it, because you can count on one hand the number of extended power outages in that time.
    10. In the end times a roving band of thugs comes around and kills you and strips your house of valuable technology, leaving your homelab setup behind and - sadly - without power. Your dream of unlimited availability has all been for nought.

    Conclusion: just replace the CMOS battery on a yearly basis during planned system downtime.
