ZTE’s newest Blade phone features dual cameras, a glass back, and face detection | Circuit Breaker Parts

Just reach for the “Flame Wrench” while working on a press, in a corrugated box plant. Within the next two minutes, you’ll know how many fire extinguishers are in that building. Box dust and the old, grease based, Letterpress ink was always a major concern when you were doing the repairs and needed to use a grinder, torch or welder, etc..

It’s still dangerous though. Cost of a 12V power supply vs a small chance of killing myself, I’d spend the money. 3D printers aren’t cheap anyway, why economise on safety?

Many thermostats are battery-operated, and once they power down so will your air conditioner or heater. Check that your thermostat is fully operational and the connections to the wall are good.

Leaving their advanced capabilities aside, the Sony A33 and A55 are also remarkably compact cameras. As we’ve noted elsewhere, because the mirror in the camera isn’t used to form a viewfinder image, it can be mounted at a steeper angle than normal, removing some thickness from the camera body as a whole (the flange-sensor distance must obviously remain the same, but there’s more room in the body for the shake-reduction system and other electronics), and the space normally required for the mirror drive system could be trimmed from the sides. As a result, the body is noticeably compact.

Japan is odd for another reason. The two “halves” of the country are on different frequencies. I believe the West is at 50 Hz and the East and North is 60 Hz. They have a collection of DC interconnects in the middle of the country to facilitate power sharing across this otherwise intransigent gap. Since the shutdown of Fukushima, those interconnects have been under quite a bit of strain, but that’s a whole ‘nother story.

Yes you can use those high voltage safely, BUT your typical DIY people don’t even bother to read or understand datasheets. These people need the proper training, but aren’t likely to be bother to go beyond the typical monkey see monkey do watching youtube and think they know it all. I have seen enough of bad layouts of the average projects that doesn’t even understand that the creepage space between the primary and secondary side of an optoisolator aren’t meant to be for routing!

I worked in telephony for many years, and the ring voltage can be as high as 180 bolts at various frequencies, but, rather low current. In really old telco systems it may also be a square wave.

Alpha mount. The Sony A33 accepts Alpha-mount lenses from Sony, and is backward-compatible with older Minolta or Konica Minolta A-mount lenses, allowing use of a huge range of both current and historic glass. Compared to single-lens direct view cameras — even Sony’s own NEX series — this will likely make the Sony A33 a much more attractive proposition for existing Alpha or A-mount photographers. While Alpha-mount lenses can be used on NEX cameras through a mount adapter, they lose their in-body SteadyShot capabilities, whereas the Sony A33 retains this capability with the same lenses. (In an earlier version of this review, we also called attention to the inability to autofocus using Alpha-mount lenses on NEX-series bodies, but this looks to be negated by a forthcoming update for the LA-EA1 mount adapter that will enable Alpha-mount AF on NEX bodies. We’ve not yet tested this update, and hence can’t comment on how NEX and SLT-series cameras will compare in this area.) Sony rates the SteadyShot sensor shift mechanism in the Alpha A33 for between 2.5 and four stops of correction.

So it’s the usual forgettable Toyota – but still hugely preferable to the godawful Prius which is a truly horrendous looking vehicle 

Heck, as I said, when I have needed to do this in the past I just used a multimeter, a terminal block, and no relaying whatsoever (ah, being perhaps complacent “qualified personnel”, eh?)

They make “plate” heaters that are metal plate looking thing with a couple of stud terminals sticking out of them as well.

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.
