the fundamental lesson is that everything you love on the internet is run by actual people, and it will disappear when it begins costing too much; either in money, time, effort, or general capacity
and there are many, many things that factor into that cost; just like how much someone can afford.

As part of the work I'm doing on my new SDR radio thing, I released a Rust library for handling the Winamp skin format. The crate can unpack skins and generate a mockup screenshot from them. It also makes it easy to access the sprites programmatically.

I went down the rabbit hole on rtl-sdr last night and found this wonderful deep dive superkuh.com/rtlsdr.html . People did some great research back when these devices came out.

This code is nasty. This code is fetid. This code is disgusting. I need to clean up this code.

I'm kind of surprised that #rustlang mpsc channels have no way of checking the length of the queue. I guess you could implement this yourself by keeping a counter on the sender and receiver sides and then sync them up, but it feels kind of cumbersome.

I feel like my FM de-emphasis filter isn't quite right. Does anyone happen to know if FM broadcasts typically have this kind of spectrum after de-emphasis? (left: before, right: after). I used a very basic Butterworth IIR filter to but it feels like the slope is too steep.

Working on this has been my fixation for the past few weeks. It's an SDR application dressed in a Winamp skin. There's still quite a lot that needs doing but it's also exciting to see where it is now. I didn't demonstrate it in this video but it does support the Winamp skin format.

I've been steadily making progress on a little Rust app that turns an rtl-sdr into an FM station receiver. The twist is that it uses Winamp skins. I'm hoping to demo it soon. I've got the 12-band equalizer working but I still need to make the classic visualizer. It's dumb and gimmicky but I like it.

Getting FM decode in uda felt like a good milestone. I did cut some corners getting there. I think I want to refactor a bunch of what I have now. Once it's in a cleaner state I'll start thinking about publishing it in a big version bump

it's a big giant mess but I just got the first FM audio decode from a broadcast station in my new SDR library (uda). dopamine get.

I've gone back to working on crates.io/crates/yagi again. I've managed to get more than 65% test compatibility with liquid-dsp so far. I would like to go back and clean up the module organization and docs soon. Just added agc and FM demod which should be useful for uda.

Progress in the uda SDR library continues. Recently I looked into how to render a large waterfall plot on the UI using egui. I wrote a little post going through some of the options I tried. cqcqcq.bearblog.dev/rendering-pi...

Last night I got to a new milestone on the uda library. After working on it for a few weeks, I can now build a generic graph very much akin to gnuradio. There are not very many cores yet, but I do now have a demo of the graph pulling samples off my RTL-SDR and doing an FFT on them. Charts come next!
