*sigh* seems like we're not nearly done with this: https:// apnews.com/article/apple-trump -computer-tariff-c01b5ce0265b0d294dd10b8966be4436 If actually done, a 100% US tariff on semiconductors is going to be very painful for assembly in the U.S. The stupid thing is this is just going to incentivize doing PCB assembly overseas, since a 20-40% tariff on the assembled good might end up being lower.…
Pebble switches from Nordic to SiFli bluetooth MCU: https://www. cnx-software.com/2025/05/14/si fli-sf32lb52j-big-little-arm-cortex-m33-bluetooth-mcu-powers-the-core-time-2-smartwatch/ Honestly it's an eye-opener about how quickly that chinese fabless semiconductor companies are moving. The SF32 SDK is pretty impressive at a glance. I'm still seeing a chunk of the bluetooth stack buried in a…
Recovering a little bit and back to worth after a 7 week leave to help look after wife and baby. Wife is still a little bed bound after a badly broken leg. Caring after them both was incredibly exhausting, but she's healing up and is steadily getting better at walking again. Many elements of this have not been fun, most notably the realities of the US hospital and healthcare systems...
Pouring deeply into US HTS (Tariffs) for work (bet you can guess why) and I keep getting dwarf fortress vibes from these item descriptions, every time.
I've been waiting so long for the new Kicad "Jobset" functionality, it's great! Gone are the days of repeatedly clicking through dialogs and remembering export settings. (Could never get earlier 3rd party tools to work well enough either).
While randomly searching my email inbox, discovered: Back in 2006 in my high-school "senior will" I left a note describing how to break out of the school's thin-client computer system to play counterstrike 😂
All the hardware vendor spam emails are getting real thirsty about tariffs "Only 5 days left to place your label order before the new US import tax hits."
I can't tell if it's helping or hurting that i'm knee-deep in a PCB layout at work - often a good opportunity to get into a really great flow/rhythm, but ol' pudding brain isn't making it easy
My brain is increasingly just a big bowl of pudding from various stresses, work, uspol, etc. Doomscrolling bluesky is incredibly informative but rough
I asked the newly-available claude CLI the following: "This codebase contains python files. Please ensure that all classes and methods within all python files have a docstring. Ensure that the docstring syntax is consistent across all classes and methods." It took 11 minutes doing a lot of very smart looking things. It only ended up touching 4/24 python files. Within those, yeah it did a decent…
Gosh, uspol is getting real bad again, it's getting terribly hard to focus at work
I've really bashed my head against older TI Impedance Track gauges without Nonvolatile memory - at least the newer ones do, but I can't tell if it'll remove enough pain ;) Is it basically necessary to factory calibrate and program a golden image, or is it realistic to try and run a fuel gauge with default values?
Does # electronics # hardware # ee mastodon have feelings on ADI/Maxim's "ModelGauge m5" fuel gauge and how it compares to a modern TI "Impedance Track" gauge? Such as MAX17201 vs BQ27Z561? Which one requires less hand-holding, and will it actually give me a reliable measurement of remaining pack capacity without needing to factory calibrate / load in a golden image?
Running into this very real RPi 4B issue, which i'm surprised still seems to be WONTFIX / "It must be a power supply problem": https:// github.com/raspberrypi/linux/i ssues/4161 Don't love that the suggestion is basically "eh, just try cranking up the VCORE and praying". I'm literally about to write a systemd daemon that looks for this MMC1 SDIO glitch and reboots. Not great.
I gave in and enabled Copilot when I needed to reinstall VSCode. I'm playing with it and still interested / exploring. For some very simple lines and comments it tends to be somewhat helpful. For anything more complicated it falls on it's face very fast. My only major concern is that I don't see a clear indication of when something is autocompleting from the C/C++ extension, and when it's coming…
Still pretty out of commission for just about anything outside of a 9-5 and sleep. Not only is it physically exhausting to have an infant baby, but it's so emotionally demoralizing to be out of extra bandwidth for so long. It stings harder, to see all the concerts i'm missing, new bars/restaurants I want to hit up, or even cool hacks on here. Everything passing me by...
Anyway, i'm very new to this, and I understand the general principle of adding layers of type safety, but boy howdy is it odd to read for the uninitiated
Also, for this example of a templated i2c register write function that works on scoped enums - I guess the most valid question here would be "why are we forcing scoped enums in the first place?" But also - why is the validation on whether or not the input enum is scoped occurring in the type signature of the return? That's weird, right? I'm also torn because "auto" is both a convenience and a…
And C++ extensions (C++20 and later)... This has been my first exposure to a lot of the stuff they've been adding to the C++ STL. Not sure i'm a fan of a lot of these design patterns. Probably half of what i'm butting heads against is probably my own resistance to change, but I really find the readability going out the window. Pretty wild that i'm often needing to…
Work project has involved deep work within the ESP-IDF and a lot of C++ extensions, and alongside the code i'm developing... feelings. ESP-IDF started out "hey, this isn't so bad" and "wow, they've done some clever things in here", but I think the honeymoon phase is over. We've run into SEVERAL nasty, fresh bugs in peripheral drivers. This chipset has been out a long time, how are they not really…
