Lenovo’s latest Yoga laptop has an ARM processor and 25 hours of battery life | Circuit Breaker Parts

I came here to post those two points! The corollaries to 1) are that should something go wrong, you have a chance if there is someone else there who knows CPR. I like mandatory CPR training for lab workers because of this. AEDs are good too. Rules against playing with things that can shock you while working alone are also good, but much harder to follow–I’ve spent decades working alone in research labs. CPR fails way more often than not, but electrical shocks are an important exception to that rule. And you almost got the extra credit for correctly spelling arrhythmia.

One of the best demonstrations I’ve ever seen, was at the Dayton hamvention. DP&L (Dayton Power & Light) set up several short poles with standard 7200 to 220 center tap transformers. By back feeding the secondaries with 220 from the breaker box, they could energize the 7200 lines and began demonstration what happens when you encounter these wires with numerous items. Antenna masts, kite strings, and even a hot dog were used to show the immense power available, and the audience was always suitably impressed.

Attack of the giant hand? That’s what we called these shots when we took them. Despite the disparity between the size of my hand and the camera body, the grip was still fairly comfortable.

When finished “fixing” things, you want to make sure, your device is still safe to the user. For this you need these testers.

HDR is a feature that’s easy to over-use, as it can quickly over-flatten the contrast of an image, resulting in a dull, lifeless photo. On the other hand, there are times when nothing else will do. I’ve shot a lot of landscape images over the years where I’ve really wished I had it; situations where there was bright sky and deep shadows, or a bright rockface but also interesting detail I wanted to capture that was in the shade. With an auto-HDR option, I often find myself trying it, but also shooting a normally exposed shot as well. I more often like the normal shot, but sometimes the HDR one is the keeper. (I really wish there were an option to have the camera capture three shots; a normally-exposed one and the the high/low exposure pair it uses to build the HDR image from. It’d be handy to be able to shoot a normal image, with the HDR shot as backup.)

It should be mentioned that any of us that have been working in commercial/industrial settings should be familiar and certified under NFPA70E. This includes, but is not limited to, how to work as safe as possible with hazardous energy sources, what the proper protection is for various levels and what is considered “safe” (working distance, approach distance, protection level, etc).

The rear seats are nearly as roomy as the fronts , which is an incredible achievement for such a compact car. Never did the kids knee my seatback.

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.

Far as I’m aware, you’re supposed to get a qualified person to fit an electric cooker. Of course, doesn’t stop me doing it. Actually more complicated than you think, it’s not just 3 terminals, there’s a dozen bits of plastic and metal in there that all need putting back in the right order.

Power outlets in homes—but not businesses and other buildings—are required to have tamper-resistant receptacles, which prevent kids from getting hurt when sticking objects in the slot. At first glance, the tamper-resistant receptacles don’t look different from the ones without the safety feature, so read the label closely if you need to buy a new one. They’re a little more expensive, but I’ll send you back for another if you don’t shell out the extra money up front.

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.

This device – and any high-powered device that’s home-built – should be regularly inspected to insure that the wiring is not degrading due to heat caused by increased resistance. That’s why the chassis has a clear lid.
