The Walking Dead developer Telltale hit with devastating layoffs as part of a ‘majority studio closure’ | Circuit Breaker Parts

Then when you step up a notch to the KV stage the safety rules change because air can now be a conductor.

I’m cynical that the non-tetany behaviour of AC results in being able to pull away. Remember that mains is oscillating at >50 x a second, so the pull-away would have to be within that cycle, as well as overwhelming the hyperpolarisation and ignoring the fact that normal neuromuscular signals are essentially pulse-frequency modulated with saturation causing desensitivity (I.e. A continuous signal is ignored)

Sega also announced that it was working with a Japanese developer to review the design and software for the console. It’s not clear if this news means that AtGames, the US company behind the poorly reviewed Genesis Flashback console, is still involved in the project as it was originally announced. It seems that AtGames has deleted the original Facebook post from April that announced that the Mega Drive Mini would be powered by its hardware.

Heat damage from increased resistance is pernicious. P = I^2 * R. At 24 amps, a resistance of a mere tenth of an ohm is 57 watts – almost twice as much as a pencil soldering iron! That’s why it’s important to get those crimps done right and inspect them frequently for signs of degradation. I will readily concede that I am not equal to a manufacturer in terms of consistency and reliability of crimps, even with a ratcheting tool. The only way I can make up for that is keeping an eye on things to catch early degenerative changes before things get out of hand. Part and parcel of building high powered electrical equipment by hand is being ever vigilant when using it.

The contacts therefore return to their normally closed position by spring power as the motor coasts to a stop.

There is no mention of what powers the module here, and I suspect it is a regular 5V, isolated SMPS. @RobHeffo suggests transformerless power supply, but that is not a good idea, for the current drawn by the ESP the capacitor will be too big. There are alternatives, like this guy, LNK306 : http://www.mouser.com/ds/2/328/lnk302_304-306-179954.pdf . It is not isolated, but the thing is probably the best cost option for such a device.

The Residual Current Circuit Breaker is a tad expensive, and is probably overkill for most hobbyists. A Ground Fault Circuit Interrupter outlet, (GFCI), is cheaper to buy, cheaper to have installed, and a *knowledgeable* do-it-yourselfer can install his or her own. If you are knowledgeable about electrical wiring and codes, but don’t want to change an outlet in your house, you can buy a GFCI outlet and some regular outlets and make your own ground-fault-protected power bar, as a correctly wired GFCI outlet can protect additional regular (cheap) outlets as well. Alternatively, I’ve also seen GFCI units that plug in overtop of regular outlets and add protection to them.

Maximum video length is 29 minutes or two gigabytes per clip, whichever limit is reached first — although if SteadyShot is enabled, this limit is slashed to just nine minutes per clip, likely due to sensor heating issues when using the sensor-shift stabilization mechanism. Full HD videos are recorded using 17Mbps AVCHD compression, while the lower resolutions are saved with MP4 compression, at a bitrate of 12Mbps for 1,440 x 1,080 pixel video, or 3Mbps for VGA video. Movie capture is started and stopped with a dedicated Movie button located just to the right of the electronic viewfinder, within easy reach of a thumb press.

And now you know why companies react the way they do. It would be like someone going around deliberately ruining your reputation, and there’s little you could do about it.

NEW YORK (AP) — Wells Fargo will pay $575 million in a settlement with attorneys general from all 50 states…

I to have worked with high voltage systems. My point was that it needs to be treated with a bit of respect or it WILL kill you even if not immediately. My friend was an electrician of many years. And sure, I hear lots of stories of how people get away with this and that, but that is just that they gotten away with it so far. They could be dead tomorrow.
