Remembers me of an incident when my mother asked me to fix the extension cord for the electric lawn mower – “please check the cable, the garden worker complained the mower does not work”. I opened the socket type end of the cable, saw a dislodged contact spring and wanted to reseat it. Then I had to feel the other end was still connected to 230VAC mains. It just did not think of thisbefore… But luckily it just stung a little. I pulled the plug and continued my work.
While not quite as light as the Olympus E-420, which lacks an in-body image stabilization mechanism, the Sony Alpha SLT-A33 is certainly in the same ballpark. The A33 weighs 17.3 ounces (1.08 pounds, 492g), with battery and flash card (but no lens), while the Olympus E-420 weighs 15.7 ounces (0.98 pounds, 445g) loaded but without a lens. The lightest SLD, Sony’s NEX-5, weighs just 17.7 ounces (1.1 pounds, 502g) loaded and with its kit lens attached — just 0.4 ounces more than the A33 body without a lens.
I was looking for a high power capable latching type to stop my old car from draining its battery… Came across this.
I mean really this shouldn’t be a big deal. Resistance heating that you plug into the wall has been done in millions and millions of devices for basically a century. When you really think about it, a toaster is probably WAY more dangerous than what is being proposed here.

AC may have “won”, but now we need to upgrade to 400 Hz! (smaller transformers, less eddy losses) B^)
NEW YORK (AP) â Wells Fargo will pay $575 million in a settlement with attorneys general from all 50 states…
It takes volts to push amps, and if your body tripped a 1A breaker you’d be dead. For shock hazard, 110V is safer than 220V regardless of the size of the circuit breaker. But for a given power draw the possibility of overheating your wiring is lower with 220V, which is why I use it in my (American) shop whenever my equipment supports it.
You can share neutrals among, say, receptacle circuits, if you make sure that there’s some kind of disconnecting means that opens all the conductors associated with all the circuits that share a neutral. That might be a multipole breaker, or it might be handle ties that physically tie breaker handles together, forcing all to trip if any trip.
Um, Though I live in Oz where we have 240 volt mains, I can see a big error in how it is explained. On, you get two different “phases” on th 110v side of things to increase the measured voltage.
Lenovo is promising 30 percent better performance over its previous Miix 630 Windows on ARM device, and a surprising claim of 25 hours of battery life to match. While the battery life sounds impressive, it’s the performance that will matter in a device like this and we’ll need to test this latest range of ARM-powered laptops to see if app compatibility and performance has improved. Most Windows desktop apps will run emulated on these ARM-powered devices, but there are some limitations. As this is powered by the Snapdragon 850, there’s also built-in LTE support for mobile connectivity on the go.
Turn off the power at the main box to the A/C unit and open the electrical access panel on the air conditioner. It is usually located where the electrical power comes into the unit. Check for rodent nests and wires that have been chewed or frayed.
