Experts suggest buying an EVSE that can produce at least 30 amps of power. Generally speaking this type of unit would be able to add around 30 miles of operating range to a given battery pack per hour. Some EVs can get along with fewer amps, but buying more capability than you may need today makes the installation “future proof” should you eventually trade in the vehicle for a model that can handle the added capacity. However, if you’re planning on using a 30-amp unit you may need to upgrade the line’s circuit breaker to one that’s rated for at least 40 amps.

I suppose the other point of note is that compared to 220/230/240 Euro voltages, residential 240 is not 240 to ground. The only things that have such high voltages to ground are either corner-grounded 240 deltas (which are exceedingly rare) and 480/277Y systems (which admittedly I do a lot of work with). I also really like how in the US we have such an extensive system of completely non-interchangeable, unique connectors for all the different voltage and phase combinations that one might find (thanks, Harvey Hubbell!)

The Sony A33 uses the image sensor itself when metering, and considers the overall image as 1,200 separate zones in performing metering calculations. Metering modes include Multi-segment, Center-weighted, and Spot, and the metering system can function from -2 EV to +17 EV (at ISO 100 equivalent with an F1.4 lens). An autoexposure lock button is provided, allowing metering to be locked from a specific portion of the subject, then the overall image reframed as desired. +/-2.0 EV of exposure compensation is available, in 1/3 EV steps. The A33 also offers a three-frame exposure bracketing function, which allows a step size of either 1/3 or 2/3 EV between subsequent frames. Shutter speeds from 1/4,000 to 30 seconds are available, as well as a bulb position that holds the shutter open for as long as the shutter release is pressed. Flash X-sync is at 1/160 second. White balance options include auto, six presets (Daylight, Shade, Cloudy, Incandescent, Fluorescent, and Flash), plus both custom and direct color temperature (2,500 to 9,900K) options. The six presets allow +/- 3 step adjustment, and there’s also a color filter setting that provides +/-9 steps of magenta / green compensation.

Even though they are more expensive(dropped under 20 thought), you can already find the wifi version of this. Just search for wifi smart socket and you will find some.

I can’t speak for the Model 3 since I don’t know anyone who owns one yet, and Tesla has removed charging rates at 110 volts from their distance calculator.

Actually, while HDR is the more glamorous feature, Sony’s Dynamic Range Optimizer (DRO for short) deserves some attention, as I found myself relying more on it than HDR to manage tonal extremes. Most every camera company has some sort of an exposure mode that adjusts exposure and/or contrast to help avoid blowing highlights or plugging shadows. After several years of tweaking, I think that images shot with Sony’s DRO now look better than most. DRO defaults to the Auto setting on the Sony A33 and A55, and most times I checked, I liked the tonal balance of photos shot that way over that those with DRO turned off.

Thanks for the pointer, it looks promising! The RF-controlled remote switch appliances that can be found for a few dollars are self-contained, I would think that a Wifi-based one could also be? Having a separate wire coming out of the box seems like an extra hazard to me. If you keep the thing self-contained with only mains-in/mains-out, I would think it is safer in the end, and removes the internal complexity of optocouplers.

There are notable advances in interior quality and function, most significantly with the dash getting a complete overhaul that includes better materials, layout and an eight-inch screen operated by buttons and touch as standard. It’s both smart and reasonably intuitive, albeit slightly short of some of the slickness of VW’s various systems. As is common in the class, Toyota has expertly put the best materials where you are most likely to see and touch them, with hard, basic plastics mostly hidden in corners of the car.

Thanks to the MOVs’ high energy dissipation, they can be used to suppress lightning and other high-energy transients found in ac power-line applications. They’re equipped to withstand large amounts of energy and divert this potentially destructive energy away from sensitive electronics located downstream. MOVs, which are also used in dc circuits, come in a variety of form factors (Fig. 1).

You really should drop the 110/240 volts statements and use 120/240 volts for residential installs. I don’t think 110 volts has been used since Thomas Edison.
