Yesterday's sewing! A little corset cover with a bust ruffle, a sort of old-time type of padding to achieve that iconic Edwardian silhouette. But also because I was just curious about how it worked and had small scraps of this very thin and soft cotton laying about. Still needs a waistband and buttons, and for me to finish the basted hems by hand, later.

I'm purposefully doing the hems and placket by hand so I have something to keep my hands occupied while I enjoy my shows, but that means I want to finish at least the button placket before I put on the waistband, so who knows what order I'm going to do things in, or when. But certainly I've got something to do when I do!

Oh, I'm also experimenting with a travel bustle pad. Maria from Sew Through Time had one in a recent video, where it was a sort of flat plane with ruffles on it, that you then made into a more 3D shape when you pulled the drawstring and it looked like one could make it entirely out of cotton and wash and iron it without issue, which is not true of any of the padded pillow type bustle pads. We'll see!

@sinituulia uh! travel bustle pad that folds flat sounds like a really useful thing!
is it this video? youtube.com/watch?v=Zxs4qF8yyS…
/me adds it to the list of videos to watch

@valhalla Yes, that one! It seems like such an improvement over various little pillows that are a hassle to wash and store

Using the Pyroelectric Effect to Identify Broken MLCC Capacitors
Vintage computer hardware can fail in a variety of fascinating ways, with [Bits und Bolts] dealing with an interesting failure mode, in the form of degraded MLCC capacitors on Voodoo 2 graphics cards. These little marvels of miniaturized surface-mount technology enable the placement of ceramic capacitors with very little space required, but as they degrade over time or due to physical damage, they can cause big issues in a circuit.
In the case of the two Voodoo 2 GPUs that [Bits und Bolts] was trying to fix, the clue that something was wrong was graphical glitches, which seemed to be related to something dragging down the 5V rail. Using the standard ‘inject voltage and see what gets hot’ method, he discovered a couple of dead MLCCs and replaced them. But something was still dragging the rail down. Unfortunately, whatever it was wasn’t enough to heat up the part in question, and no sane person wants to desolder hundreds or even thousands of MLCCs on a PCB and see whether it makes a difference.
Ultimately, the pyroelectric effect was used to hunt down the culprit, saving countless hours of work. This is a property of certain naturally electrically polarized crystals, in which the material generates a voltage when heated or cooled. Materials like that used in MLCCs, for example.
With a hot air gun set to 200 °C and aimed at a specific MLCC, it was possible to measure changes not only in resistivity but also in voltage between the 5V rail and ground. The voltage spike was relatively minor for the smaller MLCCs, but the larger ones showed a significant voltage swing of around 2.5mV.
The culprit turned out to be a large MLCC, which showed only a weak pyroelectric effect and a resistivity that didn’t drop as quickly as that of similar MLCCs on the same board. After replacement, the faulty MLCC did indeed measure as faulty, and the card’s 5V rail now showed a healthy resistance level to ground.
In addition to knowing what kind of resistivity you should measure on a PCB’s voltage rails relative to ground, this method provides a fairly painless way to quickly find a dodgy MLCC. Just make sure not to try this method on electrolytic or tantalum. Heating those up won’t go well.
We often treat decoupling capacitors as more art than science, but of course, we shouldn’t. MLCCs can even exhibit the piezoelectric effect, too.

@miles mi mandi una foto dell'insieme per vedere qual è? anche se alla fine montano tutti la stessa roba

@evan what does the percentage even MEAN?
The US is Rome. We have and always have had serious issues, domestically, including being in the throes of teething for a country with under 250yrs. However, being top dog in a global scenario means your domestic safety is directly, inextricably linked to a stable, mostly safe world.

«Quando il ghiaccio gela, tutti gli escrementi salgono alla superficie. Così, quando la dialettica si gelò, si videro risalire tutti gli escrementi sacri della dialettica. Quando il futuro è congelato, o anche già il presente, si vedono risalire tutti gli escrementi del passato.»
