The easiest way to revolutionize your computer’s audio | Lrd12 Overload Relay

”Just like with laptops and mobile phones, sophisticated new features sometimes require new hardware,” Sonos said in its blog post today. “The computing platforms and software architecture in some of the older Sonos players simply don’t have the horsepower to support AirPlay 2. But by taking advantage of newer Sonos hardware, we’re able to make AirPlay 2 content available throughout the house on speakers old and new.”

We frequently come across warm circuit breakers, warm dimmer switches, and even warm electrical panels during our home inspections. So how warm is too warm? It depends. I know, it’s kind of a blowhard answer, but there’s no one-size-fits-all answer.

LOL– I stepped into doo-doo deep enough to over top chest waders, I’m over six feet tall, so that’s deep doo-doo. First I was surprise to learn that the heated beds weren’t heated by line voltage, IMO that’s a no brainer. Appliances across the word use line voltage to produce heat with no shock hazard present when use properly. Getting back to the deep doo-doo. Hackaday does present instruction posts. Line voltage is useful resource that is avoided because of irrational fear. I’m calling irrational because the fear is due to ignorance. I suggest Hackaday create instructional post on how to use line voltage in a way that’s safe to life and doesn’t cause property damage when something goes wrong. Peer reviewed studies and guidelines information is preferred.

Remarkably, this big battery doesn’t affect the utility of this not-a-crossover. Interior dimensions, including the 100.9 cubic foot total passenger volume and 19.4 cubes of luggage capacity, matches that of the standard Niro. That picture of the cargo hold shows a small bag that carries the charging cable, but it’s removable and fastens anywhere on the floor with hook-and-loop fasteners.

FreeSync is available on the NU8000, Q6FN, Q7FN, Q8FN, and Q9FN. Once you’ve installed the latest firmware on one of those TVs, you can find it under Game Mode in the settings menu.

I’m renovating my basement, and putting in a 240V line to my garage. Just for something to do, as I don’t have an EV.

Window AC units blast for hours at time and use massive amounts of energy. An extension cord—and usually even sharing the circuit powering your AC with something else—overloads the wires. If they get too hot, the wires could short out and start a fire. Make sure the unit gets its own circuit, meaning a switch on your electrical panel dedicated to your AC and nothing else. Here are 11 more home safety risks and how to avoid them.

Even if you have 20A circuit breakers, 15A is going to likely be the circuit limit because most heavy-duty extension cords you can get are only rated for 15A – which, again, means charging at 12A.

Once got electrocuted from a computer monitor though, that a relative thoughfully gave us without a case. I was reaching underneath to adjust the brightness or something. Touched something live. The monitor was on the floor, with the 8-bit computer (a Spectrum). My hand touched the live PCB, jerked away, bounced off the floor, and back up to the PCB again. Eventually my sister switched it off at the socket. Bit stupid really, I wouldn’t let kids near something like that, but…

Comparable relay product datasheets from Omron suggest that without appropriate heatsinking, the current limit should be in the range of 4A to 7A.

Now that’s something … And for other commenters: of course exposed mains voltage is dangerous, lethal even. But why would it need to be exposed? It could be made like Davic’s hack, or in countless other ways that are safe. Hide heating element under thermal mass, use secure connectors and proper grounding.

I don’t know if the heat is high enough but mirror heating pads can be quite small and put under a sheet of glass would be quite effective.
