How Intel’s 9th Gen chips show the way forward after Moore’s Law | 19mm Momentary Push Button

“If you can power the logic side with some +5V derived from mains, there is no point keeping the optocouplers, right?”

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.

Oh, and if you want a car charging hack, there’s always the Hydra: http://hackaday.io/project/3939-j1772-hydra

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

Unfortunately, by in large, the comments for this article were unnecessarily negative, and downright factually inaccurate.

Called the MPSMv2, the core of the project is the ESP8266 module. The dev board itself can support anything with GPIO pins, whether it’s an Arudino, Raspberry Pi, or anything else with those features. Flashing the NodeMCU firmware is pretty much all that needs to be done in order to get the device up and running, and once you get the device connected to your WiFi you’ll be able to control whatever appliances you want.

One aspect of ac motor protection is the surge-withstand capability of the motor itself. Paragraph 20.36.4 of the NEMA motor generator standard MG-1 defines a unit value of surge as:   u × VL-L (or 0.816 × VL-L) where VL-L is the line-to-line voltage of the ac power system.

Then when you step up a notch to the KV stage the safety rules change because air can now be a conductor.

These ratings on the data tag tell us exactly what minimum ampacity the circuit must be capable of carrying as well as the maximum size the circuit breaker or fuse may be able to protect the circuit against in an overcurrent condition.

We’re pleased to report that the EVF in the Sony A33 provides better dynamic range than most, and does a decent job of preserving highlight detail in high-contrast scenes. The slight distraction caused by the "rainbow" effect is relatively easy to ignore most of the time. Sony specs the EVF as having 1,440,000 dots, of which 1,152,000 are effective in the viewfinder display. We believe that the company is following precedent here, by reporting a dot count as if each pixel constituted three separate color dots, rather than being time-multiplexed. If that’s the case, the actual pixel resolution would be 480,000 total pixels, of which 384,000 are effective in the final image.
