  3. 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. 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!"

  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.

  19. 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.
