First come up with some numbers about the total number of power packs installed versus the number of fires. I'm quite sure they have considered the risk of fire versus the distance between the units.
Based on those numbers, this is "acceptable risk"?  :-DD
The site's not designed at all for fires of this magnitude. The containers packed too close, there are no fire breaks anywhere with ceramic or brick wall in the rows. Mr Fireman ride your bicycle to get in there.
It's not far from a disaster kind of situation.

It might not be Tesla that dictates pack spacing and site layout, Neoen maybe- but it's a copycat error that's everywhere now. Nobody planned for this kind of event.

Another issue is damage to the AC bus wiring would take out that entire row and everybody grab a shovel to fix that. In the electric utility industry, above ground cable trays are used for good reason- you can easily replace or add cables as needed, they are completely serviceable, transformer fires included.
Here it's underground and cooked due to the fire, not an easy repair. I don't know the intermediate bus voltage they chose.

The crane looks feeble with tiny counterweights so I can't see it moving a loaded powerpack, and the crane likely just there for construction afterwhich it's taken down.

I always thought that crepes and pancakes were essentially the same thing and can be eaten with either a savoury or sweet topping, no?

They are, the French just like to give 'em a fancy name and charge you twice as much for them.  :P

Eh ?! GRRR !!!

If you come across a restaurant here trying to sell you pancakes and calling them "crêpes" in the menu card... you are well entitled to report them to the appropriate authorities ! I don't know how it's called in the UK... " DGCCRF" over here...  They protect consumers against crooked restaurants and any company selling stuff to consumers in general... they mean well but are massively understaffed so in practice 99,9% of the scumbags restaurants screw you and have not much to fear... at worst they might get a slap on the wrist and will promise they will improve.. yeah right....  :scared:

Repair / Re: Use of the fuse on the XLR output of a dj mixer
« Last post by Yamin on Today at 10:43:05 pm »
Guys another (maybe) interesting curve ball - basically when my customer brought in the faulty mixer in to my shop his complain was that there was a buzzing (the sort of buzzing you get when you have the jack connected in half way into an amplifier) sound from the PA when he had the mixer connected to it. Nothing connected to the inputs just XLR outputs to the speakers. This has been his setup for years and no issues. So he changed the mixer with an exact working mixer - same cables,PA,power cord/outlets etc. and no buzzing.
When I got the faulty mixer before opening up as usual I checked it and I didn't get the same issue as him. I didn't hear any buzzing and I got good signal out of my speaker. So after trying to recreate the problem that the customer had. I only got the buzzing when I had one end of the RCA connected to the Line input and the other end of the end of the cable not connected to anything. The buzzing goes if I connect the loose end to my signal source. I noticed that when I had the buzzing, when I touched the outer jacket of the RCA which was connected the buzzing noise does change.
When I opened the unit  the fuses were open. Bypassed them put the unit back and it works. I don't get the buzzing when I have one end of the RCA connected and the other end loose as before.
I was hoping someone could explain why this happened, and why it was different scenario for the customer. Also I wonder why I got any sound in my speaker with the open fuses, because it's my understanding that with a differential input (which I believe my speaker would have) needs the 'hot' and 'cold' signal to amplify the signal or one of them needs to be grounded which wouldn't have been the case with an open fuse at the 'hot' output of the mixer.
Thanks in advance

Other than being flat and round things, no I don't see the commonality between the two ?!  :-//
Crêpes are paper thin and much larger in diameter, like  a foot.
Most of the time I eat them either with no topping at all, or a tiny bit of super fine powder sugar, and of course a  pint of fresh milk straight from the fridge.. but that's just me, most people here don't dream milk... every body makes fun of me, treating me of cow... but I don't care...

But yeah the idea is to put topping on them. Many people here love to cover their crêpes with a ton of "Nutella" (which I hate). Of course if you go to a crêpe restaurant, a " crêperie" as it's called, they do nothing but crêpes so of course they will offer a million and one different toppings to try and extract as much money from you as possible.. business is business !  :scared:

Don't even get me started on frogs legs or escargot  ::) >:D

I am 43 and I have yet to see with my own eyes someone here eating frog legs or escargots.... but I have an uncle who used to grow these little bastard to sell them and make some pocket money... so I think at least some people do eat them... but in every day life no, never seen it... and as for me I think I would rather taste Marmite rather than be forced to eat frog legs or escargots... their is a scale even among abominable things...

Isn't long press already used to get to settings from the main screen?

I think double click from the main screen is a good option, because click right is already taken by tip selection, click left for standby/sleep

I figure I'll replace the caps.  Not sure what else needs to be done.
- don't forget about film X2 caps in a power supply.

The simplest solution if you just need 24VAC@50 and aren't picky about waveform is to get a small 240V inverter for auto use and connect a common 240-24 transformer with a capacity of something like 40-50VA to be one the safe side.

Hmm you gave me an idea. Maybe selecting the setpoint, and quickly doing a long-press...
The main thing is to not cause trouble with other settings. There are a lot of checks everywhere.

RF, Microwave, Ham Radio / Seeking suggestions for new Nanovna.
« Last post by WPXS472 on Today at 10:35:19 pm »
A while back, I bought one of the first Nanovnas that only covered to 900 MHz. I never used the thing because I wanted to use higher frequencies, and the available software wouldn't work on my Windows XP machine. Some time passed, and someone told me there was a version that used "N" connectors instead of "SMA", and had a 4 inch screen. I bought one of those with great expectations, but was disappointed that it couldn't be used for single frequency measurements. I have spent some time recently on AliExpress and eBay looking to get a newer one. I find the sheer quantity of different ones confusing, and cannot make up my mind which one to purchase. Does anyone have a suggestion based on experience as to an exact model and vendor I should buy? I like the idea of having a 4 inch screen, but I plan on using it hooked to my laptop most of the time, so that isn't a strict requirement. I would need it to go to at least 2.5 Ghz, and be able to do single frequency measurements.

I bought myself a N9340B, noticed a similar debug connector and then spent months debugging and dumping decompiled code using the VXWorks console and all the wrong type of decompiling tools.  Eventually I found that all the correct licence codes were output via the console as a debug message whenever you entered any correct or incorrect licence via the instrument.   Too easy.  THEN this post popped up and people who knew what they were doing had it cracked within a few days in between dips in the pool!

I've now got a N9342C, and unfortunately I don't think the SCPI method in this post works - tried it once.  I found a way using the VXWorks console, adding breakpoints and dumping memory locations. 

To get started, see attached, and this;

And you'll need this;
cid
cid123456

And you'll hopefully see the attached bootup sequence and login.  Baud rate I think was either 19200 or 57600.
