Full-time autofocus. There are several advantages to the use of a translucent mirror in place of a traditional single-lens reflex mirror mechanism. The Sony Alpha A33 uses the design to allow it to simultaneously provide a live view feed with full-time phase detection autofocus. Most of the light is transmitted to the image sensor, while a smaller portion is delivered to the phase detection AF sensor, where it can be used to perform focus adjustments — even during live view, high-speed shooting, and movie recording.

I think the only conceivable danger to using relays would be that they could weld themselves shut. But in this case, the relay contacts are rated for 30A and I’d not be likely to exceed even half that. The only other failure modes of relays are safe (the relay failing to close, for example).

No I don’t want one, because I have a computer museum and I don’t feel the need to instant-wipe all my floppy disks at the flip of a switch.

There’s a lot of FUD in the comments here about extension cords (which if you know what you’re doing, you have some 12AWG SO and call it a day, 10 if it’s really dang long) and in terms of current, if you screw up and overload a plug you have a handy-dandy circuit breaker there for you. If you want to say I can’t trust that, you have other issues. I wouldn’t want to try this in a house with K&T, which I didn’t know was still so prolifically installed until I moved to the Midwest.

I had my poke. Mostly people saying “may” or “could” invalidate your insurance and advising caution. Which is sensible enough. Also mention of laws mandating a professional installing things like new wiring for cookers, and other kitchen / bathroom stuff. Makes sense since there’s water about. This is the UK that I looked up, since that’s where I live. Our electrical standards are pretty high, mandatory ring mains, limits on spurs and wiring length, and even our mains plugs have half a dozen safety features built in (protection against the agony of accidentally stepping on one not included).

Samsung is rolling out an update for its 2018 lineup of QLED TVs that enables FreeSync, which allows for smoother gaming without screen tearing. The company talked up its partnership with Microsoft’s Xbox division during its unveiling of this year’s sets, and this is yet another feature that embraces the capabilities of the Xbox One X.

I think this could have failed purely due to the inadequate heat sink, made worse by elevated summer temperatures. Add the possibility of counterfeits in, it was doomed to failure.

The triac can handle 8 amp continuously and upwards to 60 amps in surges. But the 8 amp is if heatsinked enough. If you insist on a 15 amp capability replace the triac with a 25-30 amp model instead. But will *still* need heatsinking. I triac usually drops upwards to 1 volt, so pushing 15 amps in a triac regardless of size will generate up to 15 watts, and that will generate a *lot* of head in a hurry.

I recently spent 2 days troubleshooting my main PC because it was shutting down under even normal load, let alone trying to mine cryptocurrency. (I mine on my daily-driver hardware, not investing in a dedicated rig)

For the person who jumps up and says “coatings insulate the water from the trace”, well no it doesn’t, we are talking about AC voltages and water that has formed over a large trace (even insulated) forms a capacitor that will conduct AC even when you have a DC insulation. Even if it did you then still have the exposed solder pads.

The plug-in Kia Niro has an 8.9 kWh battery (vs. 1.6 kWh in the regular car). You can quickly estimate the amount of kWh you used in the week as long as the battery was fully drained every time you plugged the car in (it’s fully drained if the gasoline engine kicks in) and you know how many times you charged the car.
