Hey #electronics nerds, where do I get a bunch of those ONLY in red and black? Rainbow is cool but *each* of my breakouts and spiders needs red and black jumper wires, throwing things out of proportion... #DIY #askfedi

#Censorship in #LLM s is achieved by fine-tuning. What are the most current base models available to run locally, without censorship, and without tuning to fit a specific task? It's kind of hard to figure out from huggingface model sheets.
How do I modify builtin #Javascript objects? In #Firefox I can do: Object.defineProperty(window, 'performance', { value: undefined }); but if I put it in #Greasemonkey it does nothing :( #coding #programming #web #userscripts #privacy #paranoid
#photography question: Do #macro converters reduce quality a lot? Vignetting, blurring, chromatic aberration? I'm kinda weak on #optics this advanced. I wonder if I should buy one. I already have an extension ring but attaching it is a bother. Are converters sensitive to optics quality? Used […]

Solder paste on a PCB is like salt on a dish. It's easy to add, but difficult to eliminate. #SMD #soldering wisdom №684: not enough solder paste is strictly better than too much. Unless you like bridges. #electronics #diy
I enjoyed #rsync remote file completions for a while, but I upgraded to #Fedora 44 and now it chokes a few directories deep into the path :( I suspect some #bash expert failed on a whitespace inside the directory. #linux #filesytem

3rd attempt at #ESP32 . Lessons: - Pay attention to values - Don't cross wires - Use flexible cables or you'll tear off pads - Verify design rules or you'll forget stuff - Break out #UART even if you think you won't need it (you will) - #UVTools has #Gerber […] [Original post on fosstodon.org]
Hey writers, how about #ISBN, but decentralized? Without the payment, the copyright, or the doxxing? For new #zines , manuals, novels; political, personal, or just chill? Digital and paper? Is there any standard already which I just missed? #books #writing #databases
Achievement unlocked: Cross the USB data+ and - wires on the same board, twice. Board failure unrelenting. I mean, unrelated. #electronics #usb #microcontrollers
Czy ktoś się wybiera na festiwal Conrada? https://conradfestival.pl/ Chcę przybyć na pierwsze kilka dni, fajnie byłoby się spotkać, a wykombinować nocleg to w ogóle :P
Conrad Festival
Święto literatury światowej. Festiwal gości artystów z całego świata, reprezentantów różnych kultur i światopoglądów, związanych nie tylko z literaturą, ale też

hey @fosstodon mods, there are a bunch of accounts here that spam posts with some automatic tool without ever replying if you try to discuss the topic. It floods the local timeline and feels like they are advertising rather than building a community. Are those something you want to know about?
Writing your own ray tracer is fun bordering on wasting time. Actually using it later to create #art by modifying basic parts of the tracer is so validating: I have the last word, world! My pointless experiments do lead to something! https://gitlab.com/dcz_self/sciema #graphics #programming […]

So... How do I start a SHA-256 #git repository? Can I convert an existing one? Is there an easy alias for git init? #versioncontrol #vcs #programming
#KiCad + Dorota = plugin. https://opencommit.eu/dcz/kyperspace It helps you route tracks using 0Ω resistors. Because doing that manually is way too much clicking and accidentally lost work. I've been told what I'm doing is fighting KiCad, but if the plugin gets me through this project, then I […]

I just met a cyclist on a long-distance 4000km ride. Sounds awesome! I'd do it! Then I check the website and see the reality of digitally-burdened world: Participants must install the official tracking app. What app? There's no word about it. I think it's safe to assume it doesn't run on […]

#codeberg theory: no #LLM projects. Practice: your non-LLM experiments will likely not get booted (but may still). > So while the following use cases are discouraged (similar to private repositories), they are likely to be tolerated in practice: > Side projects and experiments with little […]

You can use a buck converter as a buck-boost converter. As in, get negative voltage. I just checked. On paper. And guess what? They are nearly identical. The schematic of one turns into the other. The only difference is the negative side of the input capacitor. Mind=blown. There are application […]

You need a 1234 GiB GPU to run your program? Let me play you the tiniest... #microcontroller breakout board! The 10-cent CH32V003 microcontroller and a single capacitor make a complete breakout board. Honestly, I didn't even need the PCB. The capacitor could […] [Original post on fosstodon.org]
#SSH be like: > WARNING: connection is not using a post-quantum key exchange algorithm. Dude, that's my #N900 with an OS from 2007. It's using #rsa and I had to make an exception in two places to even make you connect. On a private network. #Quantum computers are the least problem here […]

Say hello to my #PCB manufacturing lab. Here is the 3D printer showering the board in purple rays. In those bottles live the necessary chemicals. Neutralize before disposing! They go to trays where the board takes a bath. First, a minute in NaOH to develop […] [Original post on fosstodon.org]
My #bike chain got replaced today. It was new in February when I replaced the whole drive train. So even though I wiped and oiled it every week, that chain was worth only about 4-5 months... Maybe 2000km? 9-speed, if that matters. How often do you replace your chains? #biketooter #cycling […]

Finite Element Analysis rabbit hole. #PrePoMax works passably on Linux and with youtube tutorials (thanks Indian- and Polish-accent guys) I could actually simulate twisting a rod and do experiments. Easy to use for a total newb! That informs me where to place […] [Original post on fosstodon.org]
Rapid #PCB #manufacturing . Turnaround time: about 3h. Yield: 67%. Minimum resolved spacing: 0.1mm, thinnest trace: 0.2mm. Minimum not resolved spacing: 0.25mm :S. Not pictured: days spent learning the craft, the simpler board with 7 failed attempts, the 3 or […] [Original post on fosstodon.org]
#electronics . I want to use a coil to send low-speed data across an air gap (rotary transformer). Searching the web, it looks like I'm the first one with this idea. 5V, low power sender, 20Hz times 2 bytes. 2-5 cm diameter, 5mm gap. I know I need to drive it with AC (FM?), but how do I receive?

Days since falling off the #bike: 0. 4/7 would do it again.
Hey #electronics . Can I merge decoupling #capacitors ? Pictured: 3 1µF caps in parallel. One for VCC One for AVCC One is a filter for the power supply It feels like they are all doing the same job and occupying space for no reason. What am I doing wrong? #askfedi #hacking
