User interface. Sony has retained a similar menu system in the Sony A33 to that previously featured in the Alpha series DSLRs, but incorporating the new database-driven Playback mode from the NEX-series SLD models. The user interface of the Sony A33 is generally clean and easy to understand, with the one major exception being the rather arbitrary segregation of still images and videos in playback mode. Switching between viewing stills and videos requires the user to either enter the menu system, or zoom out to the thumbnail view and select the appropriate tab. Neither option is immediately obvious without reading the manual, and photographers unfamiliar with the interface might believe they’d accidentally deleted the unavailable media, not realizing they were simply in the wrong viewing mode.

In some places, you can get 120 and 240, or you could wire up a large transformer at your mains distribution board and get what ever voltage you wish. Might need to call the local electrician to not loose any legal battles if the house burns down.

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.

Level 2 charging systems come in two basic varieties, plug-in portable and wall-mounted units that are hard-wired directly to a home’s electric service. If you don’t have a closed garage and you’ll be charging the vehicle outside, local codes may require a fixed-mount unit. Otherwise a portable charger requires no professional installation, assuming you’ve added the 240-volt service line. This type can come in handy if you own two homes or will be staying with friends or family in another town and want to take the unit along for charging at your destination.

The purpose of this project is to fabricate a heater for use in a 3D printer. Nobody is suggesting that we should somehow 3D print a heater.

Ladies and Gentlemen, I hereby nominate [cyberteque] as the replacement for our recently departed “most interesting man in the world”. Assuming he was, in fact, nearly eaten alive by a feral pig, or trapped under a hang glider under water. Double votes if he was nearly eaten alive by a feral pig who was flying a hang glider upside-down under the water.

I do not claim infallibility. I invite criticism of my designs. But I insist on that criticism be based on my work rather than be mere FUD.

GM quickly realized this and changed the default to 8 A charging to prevent fires, and many others limit at 10 or 11 A.

440.22 Application and Selection (A) Rating or Setting for Individual Motor-Compressors — The motor compressor branch-circuit short-circuit and ground-fault protective device shall be capable of carrying the starting current of the motor. A protective device having a rating or setting not exceeding 175 percent of the motor compressor’s rated-load current or branch-circuit selection current, whichever is greater, shall be permitted, provided that, where the protection specified is not sufficient for the starting current of the motor, the rating or setting shall be permitted to be increased but shall not exceed 225 percent of the motor rated-load current or branch-circuit selection current, whichever is greater.

However, experience tells me that this very minimal standard is not good practice. Modelling for 240V will only cause problems with the first over voltage transient or spike.

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.
