After 9 years of heavy use the first switches in my remote switch box of 2x8 multiple sockets started sparking badly, despite rated for 16 Amps.

Fortunately they were still avalable and the connectors are spade plugs.
Good for the next 9 years.

Holy crap. That far exceeds the maximum number of interconnected wires per box as per the USA electrical code. That would never get UL or Canadian CSA approval here.

For a regular wall box that might be a problem with 16A per life wire. This box is limited to 16A in total. And the picture shows that all wires and wagos are like new after 9 years of use. And: When leaving home this box is always switched off completely. But as always: Don't copy that a thingy at home.  :D

On cars there are diminishing returns on fuel cost and repairs. You end up paying more keeping something which is why I got rid of that fucking awful Fiat and will be getting rid of my Citroen soon.

Edit: rise in fuel prices = inefficiency liability.

Looks like we are subscribed to the same channel !  :-DD

Yes, silly eh ? Americans are now realizing what people in Europe figured out 20 years ago... out of necessity.
My Safrane will remain with me as long as it makes financial sense compared to a newer car. Newer cars being what they are, this mean my best interest is to pamper my old Safrane so it treats me well for many years to come. Whatever comes next, forced by laws sadly, is only going to be a money pit, disappointment  and frustration, and anger, and cursing. So I try to delay this disaster to as far away as possible.

Totally agree on that, I intend on doing the same with my car, although it is 9 years old, I have been the sole driver and keeper of the car for all its life and now its owner for the last 6 years, so I know all of its history, and it has never put a foot wrong apart from the time when its alternator belt failed due to a duff tensioner. It breezes through its annual MOT safety test with only small advisories, which I get done PDQ. The last time it needed 2 new tyres due to cuts in the tread, but that would have applied equally to a new car as the culprit is the state of the UK roads.

LOL no. 19-23 mpg. In no way that makes sense. Even in America.

No, I wouldn't either, but the points he raises are what I was hinting at. If you have a car that is running well, reasonably cost-effective to run and has no major body / rust / mechanical issues, then why the hell risk junking that for something like he says that is really designed with the good for 70,000 miles ethos and then scrap it for another plastic car etc, which is not good for the planet either.

That doesn't make economical sense here due to the petrol prices.

Say 2014 C3 ...  100k miles lifespan for a car at 66mpg, that's 1515 gallons. 4.55 litres to the gallon = 6893 litres ... £1.92 / litre. £13,236 for fuel

Say Vince's Safrane ... 100k miles lifespan at 34mpg, that's 2941 gallons. 4.55 litres to the gallon = 13,382 litres ... £1.92 / litre. £25,694 for fuel

If you sell the Safrane and buy a C3 with 25k miles on the clock it'll cost you £6000. In 100k miles you will be better off by £6,694.

The safrane is worth £0 when you sell it. The C3 £1200 at 100k.

Put the £6694 in the bank, buy a nice smartphone with the difference and then get a newer C3 in 3-5 years. Total cost of ownership is MUCH lower with efficient engines.

The scary thing is if I sell my C3 now it's worth £1000 more than I paid for it because the rising fuel prices are compressing the market into efficient cars.

Otherwise, you're just another proverbial buggy-whip manufacturer, obsoleting yourself out of the workplace. :-//

Good luck, my friend.

Now get the fuck out of your employee's way and let you get this job!!!

No worries Dragon, as I said in a previous message I will just ask a friend to pass me their phone and install TEAMS on it !  >:D

So what about you then, how is your job hunt ? What kind of job are you targeting ? Interesting companies in your neck of the woods ?!

Most 'scopes are useless for precise amplitude measurement. 8 bits is ~ 0.5% error.

--- End quote ---

You’re not measuring amplitude. You’re integrating and interpolating samples.

--- End quote ---

 :-// As you are integrating digitally you have to digitise the AMPLITUDE at adequate resolution. As it may not be noise you are measuring you can't average to fudge the results get an extra bit or two of resolution.

--- End quote ---

Oversampling. Higher resolution, reduces noise. I’m not saying you sample one cycle. The bolometer has a response time and lag example. It’s doing some averaging too :)

--- End quote ---

But we are not talking low noise techniques, we are talking high accuracy measurement. There is a reason why virtually all AC and RF Votage & power primary standards are still based on thermal techniques.
