  • Pis are excellent mini computers. Unfortunately, their long term reliability isn’t quite there. When I used one, I was getting a couple of lock up crashes a year. It doesn’t sound like much, but it’s just enough to be REALLY frustrating to the (less technical) wife. The tipping point is when it goes from “nice to have” to “expected”.

    I acquired a 2nd hand NUC, and it’s been bomb proof for a few years now.




  • I had a chat about this with a friend who works for the national grid (UK).

    Apparently the problem is keeping the grid balanced and stable. Basically, the grid struggles to react fast, so they plan ahead. Things like large scale solar can provide predictions on output. Home solar can’t.

    When clouds pass over an area it can cause slumps and surges in the local grid. The more home solar, the worse it gets. The current grid is designed to work top down, with predictable changes in demand. It needs upgrading to deal with large scale bidirectional flows.

    The plug in units are (potentially) even more ropey. If used properly, they are no worse than normal home solar. Unfortunately, being cheaper, there are worries over the microinverters not shutting down. Either due to the manufacturer cheaping out, or turning on an “off grid” mode.

    There are also worries about overloading household circuits. Back feeding bypasses the household circuit breakers and RCDs. They could overload wall wiring and cause fires, or stop an RCD tripping, allowing for a person to be shocked.

    I don’t know how much this would apply to the American Grid, but I would imagine it would be worse. Your grid is older and larger. You also use 120VAC which makes the current overload issue a lot worse.



  • The rule of thumb with servers is

    • Performance
    • Reliability
    • Power usage
    • Noise
    • Size

    The trick is to remember you don’t actually need much performance. A home server isn’t generally a powerful machine. What matters is that it is always there.

    A raspberry pi would actually make a wonderful server. It’s power efficient, small and quiet, with enough grunt to do most jobs. Unfortunately, it falls down on reliability. Arm servers seem more prone to issues than x64 servers. Pis also seems particularly crash prone. Crashing every 3-6 months isn’t an issue for most pi usages. When it’s running your smart home, it’s a pain in the arse.

    I eventually settled on a intel NUC system. It’s a proper computer (no HDD on usb etc), with a very low power draw. It also seems particularly stable. Mine has done several years at this point, without a crash.

    Bigger servers are only needed when you have too much demand for a low powered option, or need specialist capabilities 24/7. Very few home labbers will need one, in practice.

    It’s also worth noting that you can slave a powerful, but power hungry system, to a smaller, efficient one. Only power it on when a highly demanding task requires sorting.




  • They are excellent in the hobby world. It’s generally when you need to do a bit of quick logic, an ESP32 can be dropped in to do it. E.g. change the colour of an led depending on a sensor.

    They also form the core of a lot of IoT devices. Simple sensors and relays that can connect to WiFi and throw up a simple web interface. ESPhome, tasmota and WLED exist to make this extremely easy.

    They are basically the hobbiest electronic multi tool. Powerful enough to do most jobs without bothering with code optimisation. Cheap enough to throw in and leave there.





  • There’s an interesting argument that honey can be vegan, by that criteria.

    A bee colony is not generally trapped in a hive. They are capable of leaving, if it’s not to their standards, or they find somewhere between. The catch is that artificial bee hives are amazing for bees, compared to natural locations. The only catch is the “rent” taken by the eldritch creatures. They never take too much however, only taking excess the hive doesn’t need.

    Basically bees could be argued to be paying rent, in honey, for high quality accommodation.

    I’ve not tried reflashing, but the os seems mostly vanilla android. I’ve had a couple of OS updates since I got my phone, so it’s not just fire and forget. I’m not sure about long term however. You might also have issues with the thermal camera, if you reflash. I don’t know how it’s wired internally, and whether a non custom app will play nice.

    They seem to be aiming at builders/workmen as a rugged phone with long battery life. They also seem to be trying to build a proper brand, not just a throw away one. Hopefully that means they will at least do security updates for quite a while. But that’s speculation.

    Oh, and it’s a brick, weight wise. I personally like that, but it’s quite polarising when people try it.

    I got fed up with this and ran across ulefone. Some of their phones are downright ridiculous but I’m happy with mine.

    It’s a waterproof brick with good grip and a 10,000mAh battery. Good for up to 4 days. It’s also got rubberised grips and takes a beating. Oh, it also has a headphone port, and thermal imaging.
