Xiaomi’s Redmi Note 4 has a big 4,100 mAh battery and a tiny price tag | Circuit Breaker Parts

I had the same shock at 8 years old I put my finger in a lamp socket with no bulb, Living in UK I was treated to 240v. I have never had a mains shock since (thankfully). i have had lots of other shocks though mainly non discharged capacitor’s/

Maybe they’re at the same kind of place Rubicon were during the capacitor plague, actually made by Rubicon caps were okay, exact visual copy fakes and Rulicons, Rubicows Rubycoms etc etc were not

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.

Why do the US still use 110v mains and 20A room circuit breakers? Those currents are dangerous, not the volts.

In San Diego (where I live) residential electricty rates start at 15 cents per kWh. Lower electric rates are available if you charge the car at night, but you have to agree to pay a crazy-high rate of 53 cents per kWh at other times. That wouldn’t work for me, but YMMV.

Which part is wrong? Lets use the IEC definitions of the different systems for clarity and you can educate me with some links to regs where I’m wrong, since I don’t do this for a living or have formal certifications in it. I’ve just a couple of years back installed 380v 3 phase into my barn conversion in mainland France myself and its most definitely a terra terra (TN) earthing system I put in. I had a inspection to get my certificate (certificate du consuel) to connect from a inspector, who during his 3 hr inspection tested the impedance to ground of my independant earth with a megga tester then checked all the earth pins in every socket for spec of impedance back to my earth point, all of which are wired star back to the main consumer unit (ring main is illegal here). We get presented 3 phase wires + a neutral as tails into our main consumer unit from the RCD device (called a disjoncteur) belonging to EDF (supply company) and its not permitted to bond neutral to your own earthing system under the regs.

I would build a custom circuit board, and not use soldermask on the heater side. Instead, I would bond a sheet of pyralux on the face of the heater. Pyralux is Kapton with integrated thermoset acrylic adhesive on one or both sides. 2 mil Kapton has a voltage standoff of 10KV, so electric shock would not be a problem. Bonding can be done in a standard oven using metal plates and clamps (to apply pressure), or with a special heated press.

I have been hit HARD by one leg of 440v, 3 Phase power running the 2.5 HP motor of industrial manufacturing equipment. I was on a cement floor, and wearing combat boots at the time. I am sure that helped, but my right arm and shoulder hurt with a strong, but dull ache for over a week afterwards.

I probably ought to be dead, or have some scars at least, but apparently I’m a very resistant person.

Burst depth for the Sony A33 is seven Raw or Raw+JPEG frames, and 16 Fine or 20 Standard JPEG frames in a burst. That’s quite a bit less than the A55, which can capture twenty Raw or Raw+JPEG frames, while JPEG shooters can expect 35 Fine or 39 Standard-compression frames, but in our experience, the Sony A33 makes up for this deficit somewhat by clearing its buffer much faster. This means that although the A55 will get you more shots in a burst, the A33 will be ready to start another burst much sooner.

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.

The first was working with a bench buddy on a military SSB Shortwave amp. My bench buddy assured me he had powered the system down and unplugged everything necessary, and I trusted him. I reached in with a pair of needle nose pliers to remove the plate voltage supply on the amp tube, and got hit by 26kv DC. Shouted and was teleported backwards about 3 feet, but no damage done (except a small melted bit on the end of the pliers).
