For the voltage setting, I thought that wattage equaled volts times amps? Shouldn’t the waste heat be the same regardless of whether it’s drawing ten amps at 120 or five amps at 240? Or is it more complex and nonlinear than that? I’m curious.

Translucent mirror (redux). As noted previously, adopting a translucent mirror design has allowed Sony important benefits in terms of autofocus, burst shooting, and body size, and conceivably the removal of one more mechanical component could improve camera reliability, as well. There’s no such thing as a free lunch, though, and the translucent mirror design does have some clear disadvantages as compared to existing SLR and SLD designs. Perhaps most significantly, light entering the lens is shared between the autofocus and image sensors at a fixed ratio. In the Sony A33, about 70% of the light makes it to the imaging sensor, while 30% is reflected to the autofocus module. With a traditional SLR, all the incoming light arrives at the image sensor once the mirror is raised, and the same is true of an SLD camera whenever its shutter is open. With less light arriving at the sensor for an equivalent aperture, a translucent mirror camera must either lower its shutter speed, raise its sensitivity (and along with this, the levels of noise, or the amount processing to mitigate it), or some combination of both. An increase in sensor gain to compensate for the loss may explain why we see slightly higher noise levels from the A33 versus the A560, which share the same sensor.

Driving the Niro PHEV is a better experience than the standard Niro — when I drove that hybrid, there were a few stumbles with the dual-clutch transmission when cold. It seems the larger, more powerful battery and motor combo smooth out the rough edges of this transmission. The greater electric torque makes getting off the line brisk, almost fun.

I disagree, I think L1 EVSE represent a real safety concern. People use corroded outdoor outlets, poorly wired outlets, extension cords (without proper checking for damage or heat build up), etc.

While the Sony A33 and A55′s viewfinder display led to a bit of a learning curve for tracking fast action, its buffer-clearing speed is an ongoing issue. The A55 can capture shots with amazing speed, but once its buffer is filled, things slow down dramatically. The A33, for its part, has a smaller buffer, but it takes less time to clear. The most irritating point with the A55 was that it seemed to take forever before it would let me look at what I’d just shot. This is certainly more of an issue for a relatively inexperienced user than a pro sports photographer, but I often found myself wanting to check out what I’d just shot before the next action sequence started so I could note and correct for any problems in my shooting style. If I’d filled the buffer, though, it took upwards of 15-18 seconds before I could even view the first image on the LCD — and a good while longer before the buffer was completely empty and the camera was back to its maximum burst-length capacity. Shoot RAW+JPEG and it takes 32 seconds to clear a maximum of 18 images, while the A33 only captures 7 images and takes 12 seconds to clear. Advantage A33.

The MOT cores are welded to the head, so they’re not coming loose without shearing. The sole purpose of the epoxy would be to keep the coils mounted to the cores (as well as keeping them free of damaging debris that would short the coils.) The only force the epoxy sees is from the eddy currents trying to push the coils away from the core (or vice-versa.) That energy then becomes the electromagnetic force that gets “transferred” to the ferrous cores – that are welded to the head. Since the force from the eddy current is fairly weak, there’s an low extremely low risk for such a failure. Not impossible, but it would take a catastrophic failure.

Not at all. One lumberjack pushes while the other pulls, and they’re both pushing and pulling against the ground. It’s fits perfectly.

The Sony A33 offers a lot of control for shooting contrasty subjects. Dynamic Range Optimizer (DRO) adjusts contrast and brightness to optimize the camera’s use of available dynamic range. Auto HDR modes use three quick shots to cover an amazing tonal range. (The shot on the right represents the maximum range of 6 EV.)

It’s been a week and I am almost constantly having to keep the car charging while at home just to keep up. On my previous L2, I charged every 2 to 3 days. My first problem was the outlet closest to the driveway shares the circuit with the family room. Oops, popping the breaker every time. The front of the house outlet wasn’t any better. Luckily there is a basement outlet I can drive to and get a charge with no issues.

So a 20 amp breaker is designed to take the load shift on startup. A 15 amp breaker will carry the nominal load, but that surge on startup will kick it every time. In the days before switching supplies the input voltage would vary from 108 to 115VAC where I did work. This occasionally caused breaker trips on the unprepared circuit. I learned to spec high enough to minimize that issue and keep a safety factor in play.

Semiconductors can fail, and when they do, they often fail in ways that make conduction paths that otherwise should not exist. Mix that with high voltage power and you’ve got a recipe for disaster.
