Well if you are an idiot and don’t design in a surge limiter.

Probably because it’s not a factor in device reliability.

It’s not so much Chinas support that’s the problem, it’s the lack of investment in the wests arms manufacturing. They have been bitching about Germany not supplying Taurus since the war started and not upgraded SCALP/ Storm Shadow which they could have done easily in the time frame. Same with...

Ripple current is determined by the switching frequency.

All you wanted to know about capacitor lifetime but were afraid to ask. https://www.cde.com/resources/technical-papers/AEappGuide.pdf https://www.cde.com/resources/technical-papers/reliability.pdf https://www.cde.com/tech-center/life-temperature-calculators/

FIB requires use of an electron microscope to accurately place the beam, it’s not meant for mass production but chip design. It costs a shed load of dosh per device.

It’s linked to your link. It’s difficult to think of Linns marketing department talking utter tosh, I know, but there is a first time for everything. https://www.linn.co.uk/technology/katalyst

The West has been amazingly complacent about this, China has a massive manufacturing capability, good at automation which it can sell to Russia and Russians are good engineers, it’s the corruption that holds them back. When word comes down that corruption won’t be tolerated to the extent it has...

The DAC shown in the picture is an AK4497 which is freely available.

I have one of those pairs in the second system, they have an ok bass, really nice imaging and treble but are inefficient. They use EMIT tweeters which stands for Electro Magnetic Induction Tweeter which are a copper foil etched on plastic which go to about 45KHz IIRC, NEAT audio use them and I...

Linn might be programming FPGA chips but as for designing their own, forget it, it costs a million dollars before arm will even talk to you and about the same for a wafer fab, development costs run into tens of millions. Getting the manufacturer to laser write “Linn” on the package is most...

Well we will see, maybe a bit of psy ops going on “ look at us we deterred Iran from attacking Israel, we’re well ‘ard”

Certainly the world is a bit of a tinderbox at the moment but Netanyahu and his religious bedfellows seem utterly oblivious to the danger they pose to the world and themselves by throwing lighted matches around. Israel is not a one bomb state, 60 kilo tons of explosives has been dropped on Gaza...

The big problem here is if the US ends up fighting Iran then China may take the opportunity to go for Taiwan and start supplying Russia big time and China has no supply side problems and has a formidable tech sector. Then we in a different world, thanks Israel!

I don’t think Israel will have much problem buying, money has an ability to induce amnesia, but selling products will be very different. There is rarely a single source of anything and it will be easy to avoid “buying Israeli” or investing.
