80%? When dealing with high current loads I top at 70% to allow for wobble of line voltage. For something like a Water heater I’d drop that to 50% ratings to make sure the surge doesn’t cause failure.

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.

I’ve been shocked a few times. First time, a friend and I were changing out outlets in a room in his house. He shut off the breaker for the room, and I watched him plug a lamp in and test it. I found out the HARD way, that each side of the room was ran through a different breaker… I got a quick jolt and the gerber tool I was using catapulted across the room…

Handheld Twilight is a scene mode on the Sony A33 and A55, so it doesn’t offer you much control: The camera picks the ISO setting, shutter speed, etc, that it thinks is best, and takes the picture. About all you can control is whether to enable face detection AF or not. For those wanting the multi-shot advantages but with more creative control, Sony offers Multi-Frame Noise Reduction mode. This mode lets you select the ISO you want to use, but the camera micro-aligns and averages together six shots, significantly reducing ISO noise. You get the same basic capability as in Handheld Twilight mode, but retain full control over other exposure parameters.

Getting reasonably priced SSRs that are trustworthy seems almost impossible. A 40A TRIAC costs $34. I know there’s more than the TRIAC in the SSR, but it’s not like there are that many components either… I end up using relays if at all reasonable and scratch my head when they’re not…

I would say however that relying on the relay coil is not reliable at all, and there are a variety of somewhat more accurate methods that I would prefer to rely upon.

This Kia Niro’s cargo area, in contrast, looks very nice! Interesting. Kia’s brand equity isn’t strongly convincing as a sound long-term value-driven purchase. I haven’t driven one, but it sounds like it isn’t great to drive.

I’ve been using a relay to switch a 1000W pump. http://telecnatron.com/articles/ESP8266-WIFI-Remote-Controlled-Mains-Switch/index.html

> those who haven had the opportunity to study electricity or had made the effort to study it. Can’t let Darwin wipe them out when they happens to the target market… Even worse is that there are people that want to build printers on their own, but are not qualified to wire stuff to line voltage safely.

As an example, I went to my mom’s place in the mountains, plugged in my Clarity PHEV using a 100 foot 12 gauge extension cord to an outdoor outlet that looked corroded. After an hour I checked the plug and it was hot of course, so I stopped charging, cleaned the outlet thoroughly, plugged it back in and it was cool (or just slightly warm) to the touch along the entire cord and outlet through the charging process. Using the extension cord is dangerous as there is no thermal sensor in the extension cord at the outlet or could be damaged internally. The corroded outlet was dangerous (and could have very likely melted out had I not checked it). The cord can get easily damage.
