About my previous post, I forgot to mention, it's important to use NP0/C0G capacitors. Most large-value ceramic capacitors are X7R, X5R, Y5V, etc. These age, so the "ADC" I built will become more inaccurate with time. Just be careful out there y'all taking hot advice from me.

People always want to use ADCs for things you don't need ADCs for. Instead you can just use time constants. The CH572 has no ADCs but that doesn't stop me from measuring battery voltage and the pressure on some silicone buttons. github.com/cnlohr/cnhar...

A while back I made LoLRa merch from my video. I know if you're looking at this post you don't have any friends to buy it for, but, if you want some for christmas, here's a link. (Both items are pretty heavily used, so seems like fourthwall holds up) cnlohr-shop.fourthwall.com

Imagine if there was an HTTP header for "May contain 18+ content" then we can have simple content protection for parents, without having to destroy freedom of speech and online privacy by leaking everyone's IDs? (I cannot take credit for this, but my question is serious)

I do not understand how people think frameworks like Emscripten are valid. WASM webapps should only be a few kB. The default rawdraw scene is only 10kB transfer.

Does anyone know if any of the programming language indices use linguist to determine the language used? I started going back through some of my projects and noticed they are almost all listed as C++ because linguist, without a .gitattributes keeps misclassifying them.

TFW when you pinpoint the millisecond after then internet drops out when you can start getting your steady supply of memes again.

It's still a work in progress, but I'm putting my hat into the ring of tiny IP stacks (including my new socket-less TCP/HTTP server demo) github.com/cnlohr/sfhip Thanks @BogdanTheGeek for pushing me to make a TCP stack leaner than I ever thought possible.

back in the 70s they used to subdivide triangles like this

This is binding, right?

I can't find the original post from @chordbug.bsky.social but if anything that only adds to the feeling of being gaslit.

An oldie but a goodie

Want a fast, simple, and small integer FFT implementation geared for 32-bit (ARM + RISC-V) processors? I have largely rewritten one of the more popular fix_fft implementations and got the OK by most recent maintainers to put it under the MIT license. github.com/cnlohr/fix32...

quick easy action! ✅

This guy, when I've been explaining my hobbies as of late.

The number of times people have said ______ is the future and they were right is way higher than I ever would expect at the time. It was the future then, and always will be the future.

Have any other 0603 10uF capacitors I should try? Turns out if it's an MLCC it is still pretty lame. You can't get around it by getting a cap with a higher voltage rating. Size does matter.

Some day I might tell y'all the significance of this graph.

en.wikipedia.org/wiki/Slow_vi... Such an interesting concept that people have such a cognitive bias against.

Good grief I didn't expect this much variation between various 0603 10uF MLCC Capacitors

Why do people do this? I just want to use gqrx, a small SDR app. Why do people not even think twice about the gigabyte of dependencies they bring in? Can we normalize feature requests of "please reduce your dependency tree"?

I am so glad I had the energy to just keep going after I tried all the RW flags in the datasheet.

It is so very rare my viewpoint for features lines up with anyone else's. I always feel like the odd man out. But also good to see that even when it does line up to others, the requests won't go anywhere either. At least I'm consistently not allowed to have nice things. github.com/actions/uplo...

The degree of technology VRChat users continuously come up with is ridiculous in the best ways.

Am I the crazy one? The inability to make AI go away causes me so much rage. Is it me who has become out of touch?

This truly is the worst timeline. We have git submodules in this timeline, but git clone does not by default clone submodules.

The import "brokerage charge" on my last item (not tariff or anything, just the fee UPS charges for charging tariffs) was $41. Oof. I mean the process was flawless, but I guess they figured out if you are trying to extract money from people, make it easy.

TIL you can just yolo your own RISC-V instructions.

I can't wait to get started writing this firmware. #ch32fun #risc_v

I love datasheets for Chinese parts.

I never find things the last place I look. I keep looking after finding what I'm looking for, cause I find the best things that way.

If there was one "trick" I wish someone explained in more detail earlier in my career, it was to encourage me to use LUTs to solve problems, and look for areas of their application. www.youtube.com/watch?v=Lnqq...

I am genuinely confused how despite virtually no documented support from the public, so many of these "protecting children" laws are moving ahead, in spite of being blatantly design to remove free speech. I can't even figure out how to fight it.

I love it when @jlcpcb.bsky.social CB gives you X-Ray reports for your projects.

Are there any charities you are aware of that advocate for free, open, anonymous internet? I.e. groups that fight age and identification verification laws? I am interested in contributing to fight the good fight some way. (The EFF is wayyy too wimpy see the Clearview cop out)
