BMW’s iX3 is the company’s first normal-looking all-electric car | 25 Amp Circuit Breaker

What’s the big deal? The heated rock for my herpetarium plugs directly into the wall. Nice cozy and warm. No shocks for me, no limp lizard either.

In case you hadn’t noticed, 2010 is the Year of 3D in the HDTV space, and all the television makers are rushing to add 3D capability across their product lines. Sony has come up with a clever way of capturing 3D images using the same "sweep" technology as in their normal 2D panoramas. As the camera is swept across a scene, it will naturally see various parts of the subject from slightly different angles at different points along its sweep. Sony’s engineers have taken advantage of this to add a 3D Sweep Panorama mode to a number of their cameras, the A33 and A55 included. While the 3D data is apparently stored in a fairly standard file format, viewing the 3D images currently requires connecting the camera’s HDMI output to a Sony 3D-capable television set. Sony’s promised 3D Sweep Panorama playback support for their PS3 game consoles, supposedly coming as early as this September. That’s still a bit limiting, but hopefully as 3D technology matures, various manufacturers will be able to read each others’ 3D formats.

If you had a mains-voltage shock once and got away with it, you were lucky, that doesn’t mean the voltage is safe, you were merely playing a game of Russian Roulette with Ohm’s Law and a low impedance high voltage supply. Your domestic mains can dump the hefty amounts of current your home heating, your cooker, or your electric kettle demands, so if it finds a low resistance path through you then it is going have no problems dumping whatever current Ohm’s Law allows it to through that path. The chances are if it happens to you the path will be a high enough resistance that you’ll only get a very nasty jolt and live to tell the tale, but if it’s not your lucky day the resistance will be low enough that you’re just going to sit on the end of it twitching until the power is turned off, whether you’re alive or not. That’s the gruesome truth. Mess with this stuff and you can die, end of story. You are responsible for keeping yourself safe, and this is not a joke. OK? Now to work!

You need to learn how to read a datasheet and understand the terms – without an understanding it won’t do you any good.

I’m glad you are aware of all of the many issues surrounding this kind of a hack. I spent 15 years as a commercial electrician, so the first thing that I did when I started to read this was think, “Oh, crap. Someone’s going to kill themselves.” I’m glad that’s not the case here.

I have to say up front that I’ve never been a fan of EVFs. While they do permit much more information overlay than conventional optical viewfinders, I’ve always felt that EVFs’ limitations have outweighed their advantages. In particular, EVFs usually have limited sensitivity and dynamic range, not to mention low refresh rates and poor resolution when compared with the view through a conventional optical viewfinder.

I don’t specialize in installing dishwashers or washing machines, so please don’t call me about them. You’re better off finding a plumber.

In reviewing my experience with the Sony A55 and A33, it’s interesting to find so many of my notes and so much of my attention directed to the viewfinder display. Were I not already so familiar with Sony’s multi-shot exposure technology, the camera’s multi-shot features would doubtless have commanded more of my attention, as they’re worthy features indeed. That said, though, the viewfinder turned out to be absolutely integral to my experience with the camera.

When it comes to celebrating the arrival of 2019, Clark County’s got everything you can think of, plus a little…

In my experience, the more people know about electricity, the more cautious they are. And the more they have to deal with dangerous voltages, the more cautious they are. With few exceptions, most Youtubers you see doing dangerous stuff online have no idea what they are doing. Speak to a decent electrician and you’ll see they work more safely than most engineers and thousand time safer than amateurs. We don’t really need electrical cowboys showing off how dangerous the stuff they do is.

True, but I have never seen a product use them. They will probably become popular with wifi powered stuff.

They’ve lifted 200kg so far, and it looks like a pretty cool addition to a shop already packed with other builds, like their MOT spot welder and a propane tank sandblaster.
