VLC is blacklisting recent Huawei devices to combat negative app reviews | Lrd12 Overload Relay

If you’re buying electricty at 15 cents per kWh, then it’ll cost you .15 * 10.5 = $1.58 to fully charge the Niro’s battery, which will propel the car 26 miles, at which point the gasoline engine kicks in, which gets 46 mpg.

120V comes with a nice plug (NEMA 5-15P) that is smaller than EU’s and you can fit more of them onto a power bar. There are always two outlets in a wall receptacle. Unless you have wet fingers, 120V won’t kill you (usually). Ask most kids that stuck things in the wall outlet and have lived to tell their tale… it is very common. Aluminum wire for branch circuits in homes was all but banned three decades ago or more. I think you have embellished things a bit. Look up the history why Europe went 50 Hz, instead of a higher frequency like 60 Hz… your lower 50 Hz results in heavier transformer cores. Find out why Japan is 100V, and the country is split 50/60 Hz! There is always politics, and not pure technical reasons.

If you look at the Fotek datasheet for that relay, you’ll find that the specified heatsink does not resemble a piece of galvanized steel sheet metal, horizontally mounted with a half inch air gap under it, and set on top of a heater.

About ten years ago, when the first cheap DVD players came into Australia from China, there was a huge failure rate due to this issue. The cause was almost always blown caps, and they could be fixed by up spec’ing the voltage tolerance for the caps in the supply.

When I was a about 12, my mother decided to fault find a 35mm slide viewer. 240vac in, 6vac out of the transformer to a plug which fitted a socket under the viewer. Slide closed two metal contacts.

The melted solder was probably a secondary failure. When SSRs fail they often turn into heaters as his did and the heat from the base plate itself melted the solder before incinerating the plastic housing.

Besides the overexposure bias, I also found the A33′s metering system was prone to more variation than I’m accustomed to seeing in an SLR. The few times I had it locked down on a tripod, shot to shot exposure seemed pretty consistent, but on several occasions shooting handheld, I found significant variation between successive shots, apparently resulting from fairly minor changes in framing. I’d of course expect exposure to vary to follow changes in the scene, but the amount of variation I saw between very similar shots taken with the A33 was unusual.

As with basically every other high-end Android phone this year, the Mi Mix 3 has a Snapdragon 845 processor, but breaks new memory grounds by including up to 10GB of RAM. Xiaomi is also bundling the phone with a 10W wireless charger. A 5G version is set for release in Europe early next year.

People are so fixated by the calculation of amount of liquid per mile, they can’t–and won’t–figure it out on the basis of how much money it costs to drive each mile.

The dimmer switch for the kitchen lights was rated for up to 600 watts, but the wattage at the lights was more than this; there were ten 65-watt bulbs on this circuit. This caused the front of the switch to get extremely hot, and creates a potential fire hazard. Have this corrected.

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)
