“Main Power” means different voltage in different places. Where I am the mains is 240 Volts and circuit layout is not acceptable for this voltage. I doubt it would even be acceptable for lower Voltage.

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.

Using SO for internal wiring is something that I have often done — it is resilent, flexible, and high temperature. Also a joy to strip.

Clearing the work space and moving any furniture before I arrive means I can get in and out faster, so I can charge you for less of my time.

I design and we manufacture controllers for homebrewing beer and in 2015 we were bit hard by counterfeit FOTEK SSRs, and this was after many years of having no issues at all with the brand. Our problems started when switching from buying direct from a Chinese supplier to buying from a Amazon supplier and the mistake cost us $7,000 in one month in warranty returned products. The issue was rated product built with substandard parts – in other words 40 Amp SSRs were built with 20 Amp TRIACs!

My first thought was that the terminals were over torqued rotating the blocks, stretching the pins, and tearing the pads.

Movie mode. The Sony A33 offers high definition interlaced video capture at up to 1,920 x 1,080 pixel resolution, commonly known as "Full HD" or "1080i." While Full HD videos are recorded using 59.94i or 50i interlaced field rates, the actual sensor data is clocked off at a frame rate of 29.97 or 25 frames per second. Using the non-standard 1,440 x 1,080 and standard definition VGA 640 x 480 pixel modes, progressive scan videos are created, matching the same actual sensor frame rates. One quirk of the A33′s design is that when shooting VGA videos, the focal length crop is increased just slightly, yielding a video feed that appears to have been shot with a more powerful telephoto lens (and in the process, making wide-angle video harder to achieve). The closely related A55 model doesn’t share this feature, which we’d speculate is likely due to some limitation as to how data can be most efficiently clocked off the CMOS image sensor in video mode.

The Mi Mix 3 will be out on November 1st in China, starting at 3,299 yuan ($475) for a model with 6GB of RAM and 128GB of storage; that’s the same base price that the 64GB Mi 2S launched at. 3,999 yuan ($575) gets you 8GB of RAM and 256GB of storage. The 10GB model is a “Forbidden City Palace Museum” special edition variant that comes with 256GB of storage and costs 4,999 yuan ($720). Pricing for India and other markets should be announced soon.

You can not do it much more complicated! If you want to heat your print bed by induction, it has to be ferromagnetic to work with a commercial induction cookers coil. And using the copper coil as resistive heater is also no good idea.

I had three electrocutions with mains voltage in about one hour. It was a dark and stormy night, when I decided to try again building my own half-bridge SMPS which had tendency to explode whenever I plugged it in. It was made of two boards: one contained EMI filters, bridge, fuse and HV electrolytic capacitors, other had high-side controller, transistors, transformer and everything else. When another transistor decided that it would rather choose new Pope instead of working, I got a bit angry. I grabbed something to drink in kitchen, returned and grabbed the board in order to smash it against the wall. I forgot to unplug it first. Ouch. Half a hour later, it was still dark and stormy night, I attempted to fix an ATX supply. When I was grabbing something from behind of supply, I touched the board with my forearm. Supply was plugged, of course. Ouch. Half a hour later, yes, it was a dark and annoying night, I was still working on the ATX supply. I unplugged the supply and was inspecting the traces, my nose and lower lip brushed solder pads of those two big caps that were charged to ~320V. I went to bed with my face hurting…

There are only two conductors run from the substation to a normal one phase installation. Those are live and neutral. Though the neutral is bonded to ground at the substation through the resistor and is also connected to earth at any and all points on the cable where any work is done it is still neutral. At the house the neutral and ground become separate conductors. The neutral is treated as a live wire when working on the system, as far as I know all utilities treat neutral as another phase for safety reasons.

All this stuff makes me think it might be time to get a Faraday cage installed around my heart. Or maybe a big shunt from shoulder to shoulder.
