  1. Design token naming conventions: a practical guide. @sturobson breaks down how to build token names that scale. He covers three token tiers (primitives, semantic, and component) and walks through five naming conventions, from category-property-modifier to multi-layered structures. Key takeaways: consistency beats perfection, prioritize clarity over brevity, use semantic intent over visual descriptions, and design for growth. #design #component

  2. Соглашения именования дизайн-токенов: практическое руководство. Стюарт Робсон рассказывает, как называть токены, которые масштабируются между командами и продуктами. Он разбирает три уровня токенов (примитивы, семантические и компонентные) и пять подходов к именованию, от категория-свойство-модификатор до многоуровневых структур. Ключевые принципы: единообразие важнее идеала, ясность важнее краткости, смысл важнее визуального описания. #design #component

  3. "The forged certification marks that are different on each part in the component series is your trusted sign of Qwality."

  4. The amount of #capitalists that tell me no one has a right to another’s #labor is so #weird since a #core #component of #capitalism is #literally #someone else #owns your labor.

  5. Just a brief #factoid to perhaps save other #electronics #hobbyists some time.

    #BigClive frequently uses a particular type of crimp-contact-and-housing as a universal socket for LEDs and other leaded components. Not just any such connector will do; various #JST, "#Dupont", and others won't work, because they only grasp pins of one particular size and/or shape. If the lead is too big, it won't go in, and if it's too small, it won't stay in.

    If you want to use these connectors - and note you can get the housings with more than 2 contacts, so you can use them for transistors or weirder things too - the magic search term is "KF2510".

    The reason these work as universal sockets for leaded components is because the contact is a spring that pushes from only one side of the housing, pressing the inserted contact or lead against the far side of the housing, and therefore provides a friction fit for any size lead (within reason). Most crimp connectors instead have particular shapes for their contacts and will only "grab" something the right size and shape.

  6. So I had - past tense - one of those cheap but incredibly useful and surprisingly capable MCU-based component testers. You know the ones - they cost about twenty bucks, can identify virtually any 2- or 3-terminal device you stick in their (usually ZIF) socket, as well as telling you things like which leads are gate/source/drain, base/collector/emitter, anode/cathode, or whatever else you might want to know about a lot of electronic components.

    Absent-mindedly put an electrolytic capacitor into it tonight without discharging it. Had about 22 volts in it... hence, one ex-tester. I let the magic smoke out, without actually releasing any smoke or smell.

    Oops.

  8. For my latest #electronic design, I have invented a new type of #component, the restistor! It was an entirely serendipitous invention, and I haven't fully characterized it yet, but I expect it will prove to be a huge advance to the state of the art, and bring me considerable fame and fortune.

  11. I #volunteered at my local Repair Cafe again today. I had fun again, though still not much actual #electronics work - more small appliances and such, and a laptop.

    But a lot of small #appliances are like any other consumer-electronics item these days. They're not designed for #serviceability [1] and the electronics in them are generally a weak point - everything's consolidated onto one circuit board, with most of the functionality on one microcontroller or custom chip (depending on the device type and its price). It makes the overall #production cost of the unit #cheaper, but failures tend to be an all-or-nothing affair. Some critical component leaks its #magic #smoke and the side-effect of that is to blow up something else on the board, and the board is not easily available as a spare part. I certainly won't have a spare one in my box of components, unlike whatever the failed #component was if it had been a separate, standardized part.

    So there were a couple of "See, here's what blew up, I can't fix it, and a new one will be cheaper than trying to find a parted-out replacement for the failed board".

    The lady with the laptop was thrilled with a fairly simple #reassembly of a display bezel that popped its clips when she wiped out on some ice. That felt good.

    [1] Getting into them is usually the hardest part, the #newer it is, the #worse it gets. One-way clips that take ages to finangle into releasing. "YOLO engineering" - "no one will ever open this!"

  13. Uplevel the MySQL REST Service
    The MySQL REST Service is a next-generation JSON Document Store solution, enabling fast and secure HTTPS access to data stored in MySQL, HeatWave, InnoDB Cluster, InnoDB ClusterSet, and InnoDB ReplicaSet.

    The MySQL REST Service was first released on labs.mysql.com in 2023 using MySQL Router. During spring 2025, it was released on MySQL

  14. Measuring the characteristics of some cheap J113 / 2SJ113 n-channel JFETs I bought, so I can match them / divvy them into bins.

    Put #15 of 20 into the JFET test circuit, and the power supply's current limiter kicks in ... whoops. Did I have it turned around so I swapped the terminals? Nope...

    Take a peek at it. Slightly different marking. Still "J113", but the factory/date code is different. Put it in the component tester... it's a PNP BJT transistor, not a JFET at all, and with a pinout completely unsuitable for the JFET test circuit. If it had been in for more than a second, it probably would have let the Magic Smoke out.

    Oh, #AliExpress sellers, where would #hobbyist #electronics people be without you? Somewhere with less excitement in their lives, I guess.

  16. 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.

  22. For @technosophos , 2023 Is the Year of #Wasm with 5 main predictions:
    - #Component model will be the watershed moment
    - #Serverless will be Wasm’s sweet spot
    - Wasm will be stored in #Container #Registries
    - All main programming languages will have Wasm support
    -#Javascript will be the most popular Wasm language
