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

I was in sixth or seventh grade, playing with a transformer with a 540 V secondary, when I accidentally grabbed one cllp lead too many. The current was flowing from one hand to the other, and I could not let go. Eventually–I’m sure the subjective time was much greater than the actual time–I was able to use my legs to knock myself off of the lab stool onto the concrete floor. Hitting the floor felt so good!

If you’re totally stumped on a page of Where’s Waldo and ready to file a missing persons report, you’re in luck. Now there’s a robot called There’s Waldo that’ll find him for you, complete with a silicone hand that points him out.

Older light fixtures won’t necessarily work with energy-efficient CFL and LED bulbs. If you want to stay away from incandescent light bulbs, you might need to replace the whole fixture.

Once you’ve  established these ground rules you can then tailor your approach based on a realistic expectation of the risk involved. This process might seem rather long-winded, but in practice it should only require a moment’s thought. It’s infinitely better to take that moment to think than get an unexpected and possibly lethal high-voltage electric shock.

I’ve left perhaps the most salient characteristic of the Sony AF55 and A33′s EVF till last: It’s huge. The view through the Sony A33′s eyepiece is much more akin to that of a full-frame DSLR than that of any competing sub-frame model currently on the market. It manages this with a comfortably high eye point (and plenty of dioptric adjustment) for eyeglass wearers, at least when simply viewing the live viewfinder image itself.

two suggestions… 1. bridge it and use as a 230v rectified/ cleaned up DC as per your choice 2. as with pop up toasters and hairdriers, use convection and radiation instead of conduction. use a hot coil and duct the hot air for circulation under the bed.

A capacitor stores electricity and is used during the compressor and fan startup for extra power. It also protects the motor from damage due to fluctuating voltage. These capacitors don’t last forever and can go out unexpectedly. If you are comfortable with electrical repairs you can use a screwdriver to discharge the dual start/run capacitor by connecting terminals to short it out, and then replace it with a new one made for the make and model of your A/C. If that’s beyond the level of DIY you’re comfortable tackling, then call a pro.

The customer wasn’t pleased. I had obviously done something wrong. I showed them the paperwork with the specifications showing that the input to the dimmers was to be 20 amps. They insisted that their electrician knew better than I did.

Add in the approx. 75 cents of AC shore power I pump in every night, and it works out in my head to about 5 cents per mile. Takes a lot of words and numbers to explain that figure, but the practical impact is that every day I drove over two hours, the car bought me lunch. I feel like I’ve patched a hole in my money pocket. This is half the running cost of any other car I’ve owned, including the TDI.

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.

can’t be said too many times: foteks are known to roll over, fart and let the smoke out. doesn’t hurt to overspec by 3-5. not when playing with fire.
