All of the wire in the high current path is 10 gauge wire that was cut from SOOW cable, so it is, indeed, rated for 600V. In addition, it has 105 degree insulation, which means that it’s actually good for more than 30A. But it’s largely moot since the NEMA 5-15 plugs would only ever be found on 20A circuits (and even then, they likely wouldn’t be dedicated).

These were obviously mistakes. I would never intentionally come into contact with HT from the anode cap.

China is a shithole. Business-wise it’s like the West was 300 years ago, when your “flour” was cut with chalk dust and all the rest. Except apparently in Chinese culture it’s seen as enterprising and showing initiative, to concoct little wheezes like this for a profit, rather than the thievery our own culture for some reason sees it as.

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.

If the car achieved its minimum 44 mpg and used 3.1 gallons, that means 136 miles were done on gasoline and 117 were EV miles.

The melted solder was probably a secondary failure. When SSRs fail they often turn into heaters as his did and the heat from the base plate itself melted the solder before incinerating the plastic housing.

Here is something to think about; Those floor finishers were doing this back in the days when “the code” only specified two wire outlets. . These days that would make a few people nervous. No case ground for the sander….

Exposure. The Sony A33 offers a selection of exposure modes commonplace on any DSLR, as well as several more unusual modes. These include Auto, Auto+ (Advanced Auto), Programmed AE, Aperture Priority, Shutter-speed Priority, Manual, Continuous Advance Priority AE, Sweep Panorama, Scene, and Flash Off modes. The Advanced Auto mode acts much like a regular Auto mode, taking control of most settings, but differs from the standard Auto mode in that it can also access some of Sony’s more unique multi-shot modes, such as Handheld Twilight and High Dynamic Range. Continuous Advance Priority AE increases the maximum burst shooting speed as compared to the standard Continuous Advance modes, but does so by requiring the aperture be fixed near its open position. The Sweep Panorama mode can function in either 2D or 3D variants, and allows capture and in-camera stitching of multi-shot panoramic images by simply pressing the shutter button and sweeping the camera across the subject. A selection of user-friendly scene modes accessed through the Scene position include Portrait, Sports Action, Macro, Landscape, Sunset, Night view, Hand-held Twilight, and Night Portrait, and let beginners get the look they’re aiming for, without needing to understand the subtleties of shutter speeds, apertures, and the like.

This makes no sense when you’re designing a heater. The higher the current, the hotter the wire will be. That’s why power companies transmit power at high voltage in the first place: they want to minimize heating. 120 watts flowing through a wire does NOT mean that 120 watts of heat are dissipated in it. You’ll get a much more efficient heater at lower voltages and higher currents.

I’ve never used a 3D printer but I imagine the printer nozzle is conductive – a small misalignment, the nozzle breaks through the solder-mask, your whole printer then becomes live, blowing up the PC connected to it at the same time.

Of course, you’re still responsible for your work, but you don’t automatically forfeit your insurance just because you added an extra lamp and it caught on fire.

The potentially game-changing performance of the Sony A33′s EVF overshadows its excellent rear-panel LCD, which is a little unfair: It’s as good an LCD as is found on any other camera, and in at least one sense literally outshines them all. It’s the same widescreen ~920K-dot high-resolution LCD we’ve seen now on a wide range of cameras from a variety of makers, but its implementation on the Sony A33 adds a couple of useful twists. First, of course, it literally twists and rotates, albeit from the bottom of the body, rather than the side. This unfortunately makes it useless for composing self-portraits with the camera mounted on a tripod, but otherwise is quite helpful for getting over-the-head and ground-level shots with ease.
