New Google Classroom update makes it harder to cheat on quizzes | 19mm Momentary Push Button

The AVIC-W8400NEX flagship has a 7-inch capacitive touchscreen, while the AVIC-W6400NEX has a 6.2-inch capacitive touchscreen, and the AVH-W4400NEX has a 7-inch display with resistive touch capabilities. The receivers support both Google Assistant and Siri and can operate wirelessly via Bluetooth, Wi-Fi, or wired through a Lightning connection. Additionally, you can control your smart home devices through the units, including things like a garage door, locks, or lights.

132KV is probably safer if you don’t test it with the back of your hand. It’s not like those little neon screwdrivers are expensive. You’d think in electrician training they’d have taught him about electrocution.

Of note, too, is the fact that there is a choice of just two petrol hybrid engines, a decision Toyota says is down to there being no significant customer demand for either a straight petrol or diesel.  There’s the 121bhp 1.8-litre motor currently used in the C-HR and Prius, plus a new 2.0-litre version with 178bhp, each attached to different hybrid systems. These will be offered with the hatch and Touring Sports (estate), which will be sold in the UK.

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.

Tell that to the parents buying baby formula adulterated with melamine. The Chinese have long standing traditions that support cutting as many corners as possible. Basically, cheat until caught. And their government seems to actively turn a blind eye to all manner of this nonsense.

My friend died of electrocution while on the job. Our mains voltage here is 240V (single phase) or 415V (three phase) and not very forgiving.

Hopefully one of these days we’ll go to significantly more DC distribution all over teh place, but I often wonder if I’ll see it in my lifetime. I thought I was imagining things when I was trying to remember if Japan was 50&60, but that’s pretty fascinating.

Agreed. I work in electronics as a profession. High voltage electronics no less. Industrial size high voltage power supplies. Everything about them up to maintaining them down to component level. The comments here from people are scaring me shitless from the lack of knowledge to the over the top over complication of the problem.

I’ve been complaining for years about similar inabilities to do math with respect to diesel fuel. “Oh, but look at the high number I can calculate!” they all cry–as they pump their tanks with a fuel that’s 33% more expensive than gasoline.

In college, I was playing with our nitrogen laser which had a huge exposed Blumlein discharge capacitor. So large that a bottle with fluorescent die had been set on it. While the laser was running, I picked up the bottle, and received several 20-30kV discharges to my hand. The exit was my bare feed on concrete. I was able to count the hits afterward, because each one left a small burn mark on my hand. That hurt.

Bravo! Excellent topic, and you covered it brilliantly! Please keep articles like this coming! I look forward to more in this series.
