Electronic component scams: some companies are remarkably open about it.

If you buy components on AliExpress or similar online markets, you're probably already familiar with getting faux goods. If you're lucky, it's a clone of the actual part you wanted (transistor, opamp, whatever) with similar specs. If you're less lucky, you get a part that's the same general type, but not the one you wanted - order a transistor with particular characteristics, but receive another transistor type entirely, that doesn't work the same way.

And of course, if you're truly unlucky or you buy the cheapest listing you can find, you get a package with a completely random bit of silicon in it (order a JFET or MOSFET, receive a BJT, possibly with a different pinout...) or even a package with no actual electronics in it (receive a DIP package with proper leads on it, but cut it open and the leads aren't connected to anything, and there's no silicon die in it at all).

I happened to see this listing on AliBaba, the wholesale / manufacturer site related to AliExpress:
alibaba.com/product-detail/Scr

If I read it right, they're offering to sell you a cloned part, but they'll silkscreen whatever fake info you want onto the package, so you can sell it as a genuine name-brand part. Or maybe they're offering to remark any component you want, who knows - I'm not going to contact them to find out.

Pretty brazen.

Random #AliExpress finding...

So today I discovered why I was getting weird results in a circuit I was testing the other day. It turns out that some of the 1N60P germanium diodes I have are fakes. They appear to be just a plain silicon diode with a forward voltage of ~0.6V, rather than the actual article's ~0.25V.

They're in the right DO-35 glass package and they've been marked as 1N60P, so someone's gone to the trouble of faking it well - but I can't see why. It can't possibly be that profitable to buy genuine silicon diodes, remark them, and then sell them for just a few pennies extra, can it?

It's not like the sellers that remark a ten-cent opamp as a $10 part - I can see how that's profitable.

Weird.

Beware of the #dangers of #Silicon #Dioxide!

- Silicon Dioxide is a side product of dehydration of #asbestos
- Inhaling Silicon Dioxide causes #silicosis which is a condition that can fatally damage the lungs
- Silicon Dioxide is commonly used to contain #DihydrogenMonoxide
- Silicon Dioxide is a substance frequently warned about on packages
- Silicon Dioxide is used to manufacture #5G endpoint devices
- Silicon Dioxide is used by the #military to direct the effect of #TerahertzRadiation at the intended target
- Silicon Dioxide is a chemical known to the State of #California to cause #cancer.
- Silicon Dioxide is an essential component of #Molotov Cocktails
- Substantial amounts of Silicon Dioxide are often among trash washed up by the sea
- Silicon Dioxide, even in form of medium sized crystals, is a known "chicken killer"
- Silicon Dioxide is, as known for a long time, where the #foolish man built his home
- Silicon Dioxide is a commonly used extinguishing agent for Class D fires
- Contact with Silicon Dioxide often causes bleeding and injuries up to and including death
- Silicon Dioxide is used to enhance the effect of abrasive blasting, and can even chip away at steel
- Silicon Dioxide is often shipped alongside other dangerous chemicals such as #SulfuricAcid
- Just small quantities of Silicon Dioxide in your bed can cause #insomnia

Despite all this, even today Silicon Dioxide is still used as a building material for homes! #SiliconDioxide #conspiracy

fronde contre l'Éducation nationale 'gros' contrat à Microsoft

> Hexatrust, l'association professionnelle des acteurs français et européens de la cybersécurité et du cloud de confiance, pousse un coup de gueule contre le ministère de l'Éducation nationale qui vient d'attribuer un marché public de 74 millions € à Microsoft. De son côté, le député Philippe Latombe demande son annulation.

Hey hey, you thought there be no #nakeddiefriday today? Here we go!

Today's entry is an Infineon/Siemens SAB-C167CR-LM, a microcontroller based on the C166 core. The die is in pleasant-looking pastel colours. :-) The die has pin 1 in top left corner. I'll do a short thread.

Many thanks to @debauer for supplying the samples!

I'd rather want a #honest #MSRP than a effectivley unavailable one.

  • OFC I don't expect a board partner to accept a margin of just $4, but it would be easier to accept a 5% higher MSRP than having no stock at MSRP.

And yes, I blame #AMD, #nvidia and #intel doing #Greedflation against #consumers because I'm very certain they don't sell #silicon at cost for a fixed price per unit depending on the order size, but rather charge a cut of the sold model (similar to #ARM does nowadays for their #licensing)...
