The Sony A33 ships in the US market from mid-October 2010, with pricing of US$750 for the camera body and an 18-55mm kit lens, or $650 for the body only package.

I’ve not tried to account for phase differences (that is, power factor). It’s very naive. I measure the current via a CT and compute RMS across a whole cycle, then I find the peak voltage and do the math.

Yeah, the US connector system is a mess. I just installed a system that’s supposed to use a NEMA 6-20 plug, but the building services people installed a NEMA L6-20 receptacle (locking version). Same electrical specs, but they don’t mate. Back to lopping off the plug and wiring my own g-d connector… Arrgh.

While contrast-detection AF systems these days are much faster than they used to be, phase-detection AF generally still has the edge in terms of outright speed. It also involves less hunting around the point of focus, since phase-detection systems can determine both the focus direction and the required adjustment. On the flip side, though, contrast-detection systems generally offer more precise focusing, since the image sensor itself is responsible for confirming the point of focus, without any reliance on the lens’s focus drive and AF sensor alignment being perfectly in spec.

Then if one is only looking at getting warm water, then one can also just have the heat pump use ambient indoor temperature to make the warm water. It will efficiently give warm water, but heating the house would be just as efficient as using a large resistor. (But at least the warm water got cheaper. (and it cools down the house during summer if one empties the warm water out doors or down the sink.))

Nose Relief. The Sony A33′s viewfinder eyepiece projects back a bit, leaving a bit more room for your nose.

I’m not going to argue with your statement, it just seems funny to me that someone would tens of thousands on an Electric Car but still be using a Gas lawnmower!:)

That said. We routinely use run of the mill power resistors in the aluminum heatsinked package, you know the ones, they start with the letter “D”, as heaters. Ohms law doesn’t fucking care if it’s DC or AC, but a little RMS will explain that DC will do the same amount of work at a lower voltage. It doesn’t fucking matter because you can choose another resistor value and get the same thing with AC. A cheap temperature controller and a relay will suffice if you have enough thermal mass to average the temperature.

Regular gasoline costs about $3 per gallon where I live, so it’ll cost (26 / 46 * 3) = $1.70 to propel the Niro the next 26 miles after the battery is depleted.

I used a bridge rectifier from a stick welder, it takes 120vac down to 63vdc with no load. Out put it into a pair of MWT primary coils in parallel. Just like this one. Works but draws too much current. The field strength is around 300 pounds. The coil resistance is about 3 ohms, and draws around 20 amps.

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.

idk, anytime I’ve been shocked on the job I tend to immediately pull back – usually any screwdriver I have in my hands goes flying, and hopefully its not towards me or anyone else’s face. Which is why I use all 1000v insulated screwdrivers now. Better sorry than safe, kill two stones with one bird. You can definitely “feel” the alternating current.
