What about putting a uC in SSRs, so you can ask the think if it’s an original part or not. Propper encryption needs to be implemented of course.

[Ron] does a nice job of explaining some basic concepts like using opto-isolators. However, the real value to the video is the easy way to interface to the existing controller. A little configuration into Home Automation rounds out the project.

Not really clear but good point. I met an electrician who told me : ‘230VAC is not dangerous, I’m getting shocked a lot, it really hurts when its 400VAC. Oh by the way, I have to get an appointment for my heart !’

*Using approved LO/TO procedures which include verifying the energy sources are removed/disappated and safe

Power outlets in homes—but not businesses and other buildings—are required to have tamper-resistant receptacles, which prevent kids from getting hurt when sticking objects in the slot. At first glance, the tamper-resistant receptacles don’t look different from the ones without the safety feature, so read the label closely if you need to buy a new one. They’re a little more expensive, but I’ll send you back for another if you don’t shell out the extra money up front.

The IEC61010 category ratings on an Agilent multimeter. Medvedev [CC BY-SA 3.0], via Wikimedia CommonsYour instruments such as multimeters, oscilloscopes, and their probes will all carry an appropriate safety rating for maximum voltage, surge voltage, and current. In modern equipment this will be denoted by specified classes each with their associated voltage defined under IEC 61010, though you may find older equipment with IEC348 or other national standard ratings (Fluke publishes a handy PDF explaining these standards in detail if you would like to know more). These ratings are important in ensuring that the instrument keeps you safe as you use it.

The Sony A33 uses the image sensor itself when metering, and considers the overall image as 1,200 separate zones in performing metering calculations. Metering modes include Multi-segment, Center-weighted, and Spot, and the metering system can function from -2 EV to +17 EV (at ISO 100 equivalent with an F1.4 lens). An autoexposure lock button is provided, allowing metering to be locked from a specific portion of the subject, then the overall image reframed as desired. +/-2.0 EV of exposure compensation is available, in 1/3 EV steps. The A33 also offers a three-frame exposure bracketing function, which allows a step size of either 1/3 or 2/3 EV between subsequent frames. Shutter speeds from 1/4,000 to 30 seconds are available, as well as a bulb position that holds the shutter open for as long as the shutter release is pressed. Flash X-sync is at 1/160 second. White balance options include auto, six presets (Daylight, Shade, Cloudy, Incandescent, Fluorescent, and Flash), plus both custom and direct color temperature (2,500 to 9,900K) options. The six presets allow +/- 3 step adjustment, and there’s also a color filter setting that provides +/-9 steps of magenta / green compensation.

Yes, I know that I’m just offloading my energy use to my residential electric service (which is, around here at least, produced mostly by coal or natural gas). Let’s leave that discussion for somewhere else. The impact at the fuel pump is what matters here. Spending eight dollars or less every week to drive to and from the cube farm is incredibly appealing.

Viking if your cord is getting hot, it’s being overloaded. Time to upgrade the circuit wiring and breaker. The cable doesn’t necessarily have to feel cold, but it shouldn’t feel noticeably warm to the touch either.

PS I understand L1 will work for many people (up to maybe 40 miles per day driving), I disagree that it should be encouraged due to safety concerns and most general people won’t properly care for the L1 charger.
