By the way, the plug-in Kia Niro appears very similar to the now-discontinued plug-in Ford C-Max. I wish Kia better success with their product offering than Ford had with theirs.

Being in the controller business I’ve been presented more than one friend’s design with insufficient cooling. One friend even mounted his SSR to a decent heat sink then mounted the entire assembly inside his housing with no air circulation. His response was “it will work” and he’s had two SSRs fail that I know of. At least in his case, the steel housing kept the “magic smoke” contained!

My son replaced a C-Max with the regular hybrid version of a Niro recently. I would not use “reliable” and C-Max in the same sentence as it needed a new transmission at 77K miles (fortunately covered under a hybrid warranty), had a leaking engine (not covered under warranty), a Sync system that failed twice (covered under a special warranty extension that was about to expire), and numerous other problems mostly electrical in nature. We’ll see about the long-term reliability of the Kia but fuel economy has been in the high 40s (versus 35 for the C-Max) and all-around the Niro just feels like a much nicer car for less money. Personally I will definitely take a look at the plug-in version when I am next looking for a new car and it would be in the color of the one reviewed here so I hope it doesn’t get discontinued as Kia seems to like to do fairly often.

Sonos isn’t saying exactly when AirPlay 2 integration will be ready for release. Apple itself has yet to officially launch AirPlay 2 for iOS yet; it’s still in beta testing. So that part obviously needs to happen first. But Sonos has made enough progress to have finalized a list of which of speakers will get it. The Sonos One, second-gen Play:5, and Playbase will be updated with AirPlay 2 support. Older Sonos products — the Play:1, Play:3, and Playbar — won’t be. To help ease the pain and frustration of that cutoff, Sonos says that so long as you’ve got one speaker that can do AirPlay 2 in your Sonos setup, you can group it with older models to make that audio play everywhere. Mac Observer first reported the list of supported devices.

I recall a battery add from the 70’s or 80’s that displayed the power of a couple of 1.5V cells powering an electromagnet that could lift a car.

It may be just perception coloured by the general work environment, but a lot of the US regs seem driven by liability concerns. Too many lawyers.

Of course, after buying a 1000W PSU, I kept getting intermittent shutdowns and freezes after 30-60 minutes of gameplay or CAD work, despite remaining perfectly stable while mining for days at a time. The GTX670 has no backplate and last year a fan screw vibrated loose and fell on top of it while everything was running. The motherboard was toast so I ungraded it and the CPU (AMD FX9590), but the GTX670 itself seemed okay. Apparently not.

My testimony : 230VAC doesn’t kill if you’re lucky. Lots of people died on 230VAC (Claude François….)

But 110/120v A/C? that stuff is baby-play, as long as you realize that you shouldn’t use both hands, or use grounding straps, it just kinda buzzes, I’ve played around with TENS devices that had more (felt) kick than it…

It will only trip the breaker if you have a bonded ground. Soil resistivity has everything to do with it, and is the reason most homes have bonded grounds (the soil resistivity is too high to provide adequate current flow to trip a standard breaker). Unless you have a GFI on that circuit you can still get shocked. Earth ground won’t help you until the voltage gets high enough to cause enough current to flow to trip a standard breaker, and NEC requirements set the limit on earth ground resistivity, the limit they set ends up equaling a voltage of 600 volts required to trip a standard breaker, and that is why most (single family) homes have bonded grounds. Earth ground is only for high voltage transients.

The gate resistor will eventually short to the trace after so many cycles. It may take a while, but it will eventually happen. We had that problem years ago with a product. Resistor has to be lifted up above the trace. Traces and such seem fine for 120VAC for low current loads. Wouldn’t pass muster overseas.
