I have to say up front that I’ve never been a fan of EVFs. While they do permit much more information overlay than conventional optical viewfinders, I’ve always felt that EVFs’ limitations have outweighed their advantages. In particular, EVFs usually have limited sensitivity and dynamic range, not to mention low refresh rates and poor resolution when compared with the view through a conventional optical viewfinder.

I find it fascinating how the difference has also impacted the very different “styles” of electrical standards, construction, equipment, etc…the US has had to worry about thermal issues in different ways because of the lower voltage, but that also extended to higher voltage equipment as well, and an overall concern regarding fire (particularly in non-residential installations) when at the same time, we had a lot more natural resources piled around so in the US, we focus heavily on metallic enclosure and grounding (and the fact that our neutrals are meaningful when most Euro outlets are non-polar). At the same time, engineers were far more plentiful (and far less expensive) in postwar Europe than in the US, and the electrician:engineer ratio was very different. Likewise, that’s why NEMA and IEC in many ways are so different (NEMA is overbuilt, maintainable, easily specified but expensive and not particularly precise in application, meant for an electrician to be able to come up with the right contactor, etc.) whereas IEC stuff is more resource- and space-efficient but requires specification. Double-insulation is instead the focus in Europe, which doesn’t need any more metal to accomplish.

My post outlines the PME system. There are older systems that do run an earth / ground but they are being removed as and when they need attention. The US system is different but the number of countries using the US system is much less than the number of countries that use a similar system to the UK. I am UK based and UK trained.

people remember “the good old days” and they forget all about the horrible accidents and fires and massive death that came from ignoring fire regulations

The ESD protective wrist strap should not tie you to a hard ground, it usually has a 1Meg resistor included, just for this reason. But perhaps not every cheap chinese one has?

WIRE CONTACTOR: A wire and contactor displaying the 90°C rating on the wire and 75°C rating on the contactor (when properly torqued).

Australia is similar, except 3ph is uncommon in a house. There’s 3 phase at the kerb and each house is connected to one phase.

If you enjoy people photography and delight in taking photos revealing real character and emotion, get yourself a Sony A33 and a large memory card, set the camera to high-speed continuous mode, and let fly. You’ll be amazed at how much more intimate and impactful your photos become.

The owners manual for the Clipper Creek unit shown in the picture specifically says not to wrap the cord tightly like shown in the picture. If you do the cord WILL get hot internally even when properly wired during a long charge. It needs that open space to vent heat. The cord will stay cool if coiled properly. Whenever people not knowing otherwise coil the public chargers like that I will loosen them up.

Sega announced on its Twitter account today that the release of its Mega Drive Mini, a miniature version of its classic console, would be delayed until sometime in 2019. The Mega Drive Mini’s release was originally slated to coincide with the console’s 30th anniversary in Japan, but its global availability was unknown. Now, the company has confirmed that the miniature console will be released as the Mega Drive Mini in Japan and Europe and as the Genesis Mini in North America.

I can see exploding TRIACs happening more often on cheap dimmers and such due to under-rating the load and little to no heat sink.
