The main issue would be shock protection. A bare PCB with solder mask probably won’t cut it for UL or CE. If you have vias in the element traces, it will probably be really dodgy. On a commercial product which you can’t (are not supposed to) open and tinker with, there is probably a way to do this easily. For a DIY printer, not so much.

Senate Majority Leader Mitch McConnell has been clear that, aside from any spending bills, Republicans’ priority for the end of the year is to keep pushing judges through — and if Flake holds on this issue, it could throw a wrench into that plan.

I can’t speak for the Model 3 since I don’t know anyone who owns one yet, and Tesla has removed charging rates at 110 volts from their distance calculator.

They all have a ceramic rod or coil wrapped with nichrome wire that turn red hot. A vaccum forming table design I looked at used ceramic rods made the same way with reflectors to evenly distribute the heat. I believe all of the above (I did not verify if the table was) were UL marked.

In case you hadn’t noticed, 2010 is the Year of 3D in the HDTV space, and all the television makers are rushing to add 3D capability across their product lines. Sony has come up with a clever way of capturing 3D images using the same "sweep" technology as in their normal 2D panoramas. As the camera is swept across a scene, it will naturally see various parts of the subject from slightly different angles at different points along its sweep. Sony’s engineers have taken advantage of this to add a 3D Sweep Panorama mode to a number of their cameras, the A33 and A55 included. While the 3D data is apparently stored in a fairly standard file format, viewing the 3D images currently requires connecting the camera’s HDMI output to a Sony 3D-capable television set. Sony’s promised 3D Sweep Panorama playback support for their PS3 game consoles, supposedly coming as early as this September. That’s still a bit limiting, but hopefully as 3D technology matures, various manufacturers will be able to read each others’ 3D formats.

3-phase installations like industrial facilities and some apartments are fed with 208V 3-phase, which provide three phases of 120V to neutral, or 208V phase-to-phase.

I’ve never used a 3D printer but I imagine the printer nozzle is conductive – a small misalignment, the nozzle breaks through the solder-mask, your whole printer then becomes live, blowing up the PC connected to it at the same time.

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.

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.

You can use mains voltage if it involves already approved/CE-licensed parts that are simply wired together such as a power supply to a circuit board, but if you design and build your own part with 120 V inside, it’s on your head when the house burns down.

Fdx Advisors Inc, which manages about $3.11B and $2.69 billion US Long portfolio, decreased its stake in Dollar Gen Corp New Com (NYSE:DG) by 3,022 shares to 30,873 shares, valued at $3.37 million in 2018Q3, according to the filing.

Dunning-Kruger effect. It’s impossible to correctly estimate your own stupidity. This is the cause behind half of everything wrong in the world. The other half is psychopaths in positions of power.
