Xiaomi’s Redmi Note 4 has a big 4,100 mAh battery and a tiny price tag | Lrd12 Overload Relay

While the translucent mirror design isn’t quite as space-efficient as the mirrorless design of an SLD camera, it’s still smaller than that of a traditional SLR, most of which need to provide room for the mirror to swing upward before image capture can commence. That translates to an uncommonly compact body by SLR standards, although it’s still a bit larger than an SLD, especially in terms of body thickness. Unlike SLD cameras, though, the Sony SLT cameras all accept the entire line of standard Alpha-mount lenses, a significant advantage if you already own a large collection of Alpha-mount glass.

Then if one is only looking at getting warm water, then one can also just have the heat pump use ambient indoor temperature to make the warm water. It will efficiently give warm water, but heating the house would be just as efficient as using a large resistor. (But at least the warm water got cheaper. (and it cools down the house during summer if one empties the warm water out doors or down the sink.))

Anything below 50 Volts is considered “safe”. As in, you don’t need to be a licensed electrician to build and operate it. That’s the other thing with dealing with mains voltages in a DIY project. If you build it yourself, your insurance company won’t covery you.

With a smart charger the EV can be recharged at night and unless you are using electric strip heaters, even a 100 amp service panel can suffice. From 10 pm to 6 am there is no significant electrical demand (only the fridge or the furnace motor) to compete with the 32 amps for the EV. A drawback to L1 charging is having to leave the car plugged in for 3 times as long and having a power cord to trip over in the garage.

Nissan has said that most people who get their LEAF charging stations installed by AeroVironment will pay around $2,200 to $2,500 in hardware, permits and labor—$750 of which is for the actual charge station hardware. While the pictures are interesting in-and-of-themselves for those of us that care about what happens under the hood of all of our equipment, the bigger question the pictures bring up is what, exactly, you’re paying for when you plunk down your $750 for the hardware.

But don’t believe brand names are any better, especially if you buy them from eBay or Amazon! There is too much profit to be made remarking parts to trust any of these type parts from anyone but a major distributor like DIGIKEY or MOUSER Electronics.

As a result I wrote this article in 2015 outlining the issue, what I did to ID the problem and the solution.https://www.instructables.com/id/The-inner-workings-of-Counterfeit-FOTEK-SSRs/

To be exact: It’s the anode or acceleration voltage. Focus is usually some kV, but derived from a 100Meg voltage divider.

In the old days, waaay back in the 20th Century, you’d buy something from a vendor that had a good reputation. It was in their interest to keep their reputation, because that’s where customers came from, so they’d make sure to only buy their materials and parts from reputable suppliers. And they’d do the same, forming a chain of reliability and trust built up through experience and everyone’s mutual need to keep up a reputation.

User interface. Sony has retained a similar menu system in the Sony A33 to that previously featured in the Alpha series DSLRs, but incorporating the new database-driven Playback mode from the NEX-series SLD models. The user interface of the Sony A33 is generally clean and easy to understand, with the one major exception being the rather arbitrary segregation of still images and videos in playback mode. Switching between viewing stills and videos requires the user to either enter the menu system, or zoom out to the thumbnail view and select the appropriate tab. Neither option is immediately obvious without reading the manual, and photographers unfamiliar with the interface might believe they’d accidentally deleted the unavailable media, not realizing they were simply in the wrong viewing mode.

Washing machines etc. have their own 10-16A fuses. 3 phase 16A power is used for larger equipment, most commonly for semi-permanent installation like oven&stove combo and electric sauna stove. Those are usually connected to star, so single element in equipment will still see 230V.

You don’t need a 3D printer to use a heated print bed for 3D printing? I’d think that having the rest of the 3D printer would more or less be required to use a heated bed to facilitate printing.
