Senate committee cancels votes on judicial nominees after Jeff Flake’s Mueller ultimatum | 25 Amp Circuit Breaker

If I was working on your bedroom lighting and an outlet in your basement stops working a few days later, that’s just a coincidence. I’ll come back for the second project, but don’t expect me to do it for free because I “broke” it the last time. If I wasn’t working with that circuit, this new problem is unrelated.

I heard from an instructor that some guys from the national power company use full PPE when switching on/off old main fuses in domestic installations (230V, 15 to maybe 60A). These things are fully plastic and can be operated by everyone, so no PPE needed, but it seems like they explode sometimes – maybe because of the dust you mentionned.

You can get the domestic radio-controlled switchers, 15 UK Pounds for a set of 3 including remote. Think it’s standard 433MHz. Admittedly not Wifi but a little hub to convert the two wouldn’t be much problem. The point being all the nasty stuff’s pre-manufactured and you don’t even have to touch it once it’s plugged in. A stray radio wave’s much less likely to burn your house down, and an insurer can’t blame you for using units you bought from a reputable store. Though check for the relevant safety markings just to be sure.

And it’s is a bad advice from ESD protection standpoint as well because nothing else, like your table where the new components are laying on, isn’t grounded so you’ve just created a potential well.

I adore the Gravity Blue finish on this tester — it’s a welcome change from the sea of grey, silver, and white that fills every damned parking lot. More blue/green here again.

I don’t approve of that design. It lacks the third relay, which means that if you plug into two circuits on the same phase, you get 0 volts between the two hots, but both are still 120 volts away from ground. That means that the equipment doesn’t work, but it’s not safe to poke at. I prefer to insure that the 240 volt outlet is guaranteed to either be completely dead, or properly powered.

The net result is that, while the Sony Alpha A33 is a fair bit thicker front-to-back than single-lens direct-view (SLD) cameras, which can do away with the bulky mirror box entirely, it’s still an exceptionally small camera by SLR standards. If the handgrip depth is ignored, the Sony A33 is actually just a little smaller than the smallest digital SLR to date, the Olympus E-420. Unlike the smallest SLD cameras, the A33 still includes a built-in electronic viewfinder — and for those SLDs that can accept an optional electronic viewfinder, much of their size advantage over Sony’s SLT-series models is erased once it’s installed. Sony’s A33 thus occupies a comfortable middle ground, sacrificing little of the versatility of a traditional SLR, yet bringing a worthwhile advantage in portability.

The saw cuts in both directions, one person pulls, and the other slightly lifts and the saw cuts. then the other person pulls and the opposite person slightly lifts and follows the saw. Each person has a pull stroke and a less strenuous return stroke.

Ive had a few shocks off 220vac but nothing that hospitalized me. But I do distinctly remember a shock recieved by a friend. He had a illegal cb with a zetagi 1kw valve linear amp, it tended to carbon up its changeover contacts and loose quality on ssb so I showed him how to turn it off, isolate it, drain it down and clean them up with contact cleaner. And I kept repeatedly stressing, dont do this without doing the whole isolation things as it will kill otherwise. Well, one day it went bad in the middle of a qso, and this was to some prized russian area, so throwing caution to the wind, he sprays contact cleaner at the relay while mid conversation, while holding a aluminium microphone in other end to talk it up. You guessed it, the valve hv field collapsed into the stream of contact cleaner, threw him across the room and into a wall and his glasses were blown off and twisted by the event. His girlfriend took him to hospital and it took a fortnight before they were happy with his vital signs to declare him fit to leave. All I could say when I visited him was “I bloody told you so” but his girlfriend was up for blaming me “for showing him”, and since then I’ve shied away from showing people things that if they ignore some of my warnings could kill them.

But it seems our society is structured so that a lack of morals, and inability to feel empathy (but ability to fake it, when needed), can lead certain ambitious and capable individuals right up to where they can do a lot of harm. There’s so many political decisions, particularly in the UK, where “fuck ’em” must have been the answer to any qualms about the needy. Even to the point of ill people killing themselves, and even a few who’ve starved to death.

It happens to the best of us. We power up our project and immediately run into issues. Be it spotty communication or microcontroller reset or any number of bugs that have us mystified and picking though our code… only to find that it’s a power supply issue. Anyone who has tried doing Raspberry Pi stuff and depended on the USB power from their PC has certainly been bit by this.
