I2S Audio DAC MIDI Polyphonic Synthesizer | STM32 Tutorial #103
This video builds upon earlier videos, implementing a USB MIDI and later a polyphonic synthesizer using the STM32 built-in DAC. In this video we will be using a proper 16-bit audio DAC over I2S interface.

I2S Audio with PCM5102A DAC | RP2350 #15
In this video we will cover how to run a dual sine wave on a PCM5102A I2S audio DAC using RP2350 PIO.
It was quite hard to hit the right balance between detail and overview in this video, so please let me know in the comments how I did.

Future versions could be done with an Adafruit Propmaker RP2040 Feather microcontroller (that has a built-in NeoPixel controller) and a battery.
That was the set-up used in my Area 51 Project (and slated for my C-57D Project).

Jag kör birdnet, helt lokalt. Den kräver mycket lite resurser av datorn. Märker det knappt. Streamar ljudet från trädgården med en I2S-mic kopplad till en ESP32 och kör classifiern i en linux-VM på min dator. Sen kastar jag ner detekteringarna i en MySQL-databas och kör en liten webserver på det.

Pivot has proven to be a lot of work, but very worth it. I've converted everything to MicroPython (w/ swapping Bleak for aioble being the most time-consuming part), and he can now run on a Raspberry Pi Pico 2W. I ordered an I2S microphone chip, should be getting everything done for real next week!
the code is coding!
need to tweak a couple of the viseme thresholds probably, and then get him mic'd up and put the code on my phone or something, but for the most part, he is 100% complete 👀
