  • 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.




  • I personally suspect environmentally caused ADHD could be a thing.

    Ultimately, if the treatment methods and suggestions help, I have no issues with it being treated.

    It’s also worth noting that ADHD (and sub diagnosis ADHD) are disproportionately represented in certain groups. My wife didn’t realise she had a problem till well into adulthood. Since she was diagnosed, over half her friendship group are either diagnosed, or in the process.



  • It’s also worth noting that ADHD, as a condition, is mostly a Gordian knot of maladaptations. Built up over childhood (and beyond). While there are a lot of commonalities, you need to do a detailed investigation to pick out what bits are a problem to the individual.

    If you’re going to go through that process, then you might as well not tie up an MRI machine for no reason.

    Drugs can treat the base problem, but don’t work well without the follow-up care to repair the behavioural damage.
