Charging Your Tesla Model 3 With Just A Wall Outlet | 25 Amp Circuit Breaker

It’s good to see a snubber on the design (that’s often omitted on DIY designs I’ve seen). There are a few TRIACs that are designed to commute highly-inductive loads (“snubberless” is the marketing term I’ve seen) — may worth looking into them to reduce the BOM.

If you enjoy people photography and delight in taking photos revealing real character and emotion, get yourself a Sony A33 and a large memory card, set the camera to high-speed continuous mode, and let fly. You’ll be amazed at how much more intimate and impactful your photos become.

The MOT cores are welded to the head, so they’re not coming loose without shearing. The sole purpose of the epoxy would be to keep the coils mounted to the cores (as well as keeping them free of damaging debris that would short the coils.) The only force the epoxy sees is from the eddy currents trying to push the coils away from the core (or vice-versa.) That energy then becomes the electromagnetic force that gets “transferred” to the ferrous cores – that are welded to the head. Since the force from the eddy current is fairly weak, there’s an low extremely low risk for such a failure. Not impossible, but it would take a catastrophic failure.

Best answer: Probably. The Amazon Smart Plug was designed to work with most any product you have in your home but there are some exceptions and devices that shouldn’t be connected.

A user calling himself "Tango" over at the MyNissanLEAF forum posted them yesterday saying, "I wasn’t sure if anyone posted pics of the insides yet, so while they were [installing it], I took a couple of pictures of the innards."

Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of overvoltage conditions. Essentially, these voltage-dependent, nonlinear devices have electrical characteristics similar to back-to- back Zener diodes.

Great reasons to add L2 to your own garage, carport, parking spot: preconditioning vehicle will not reduce your SOC, lower fire risk than overloading an existing 120V circuit, more efficient charging, added resale value to your house, NEMA 14-50 outlet can be used for other things (welder, RV, heater, etc.), two EVs in the same garage, maximize off-peak charging, cool factor, etc.

Lenovo’s previous ARM-powered device was a 2-in-1 detachable tablet / laptop hybrid, but the new Yoga C630 is more like a traditional laptop that also flips over to become a tablet in the traditional Yoga style. Because it’s more of a clamshell-like laptop, you also get a polished aluminum design, and the build quality you’d expect from a laptop. Lenovo is equipping the Yoga C630 with a 13.3-inch FHD IPS touchscreen that also supports an optional stylus. There’s 4GB or 8GB of RAM, and 128GB or 256GB of storage. Ports include two USB-C and a headphone jack.

That’s also a mistake in the article, because the house ground doesn’t exactly ground the house. It just grounds the appliances. You can still have thousands of volts between a table and the wall socket ground in a thunderstorm. Even on a normal day, you have about 100 Volts per meter in potential difference just from atmospheric charges, which is why it’s a bad idea to ground the computer you’re working on unless you also ground the table, the chair, the floor and yourself.

SSRs can actually contain what is used here: optocoupler+triac or they may use optocoupler+mosfet. Just like individual triacs you will find that they suffer from the same issue: high power dissipation. A quick looks shows BT137 will burn 20W to switch a 5A load, I see 6W for the first 10A SSR I encounter. This is too much to dissipate in a small junction box isolated inside a wall. Meanwhile, a 10A relay will dissipate maximum 2.5W through the 0.1ohm contacts.

ead of single layer traces covered by the paint, what about multilayer PCB? So the traces would be embedded between two FR4. This way it would be safer.
