Power isolation (at least the idea) is to use an SN6505B to drive a push-pull transformer, a couple diodes (PMEG6010CEH probably since I have them and they're low Vf), and then a TPS7A20 LDO on the other side. The LDO has a PSRR of 92dB@1kHz, so basically nothing should creep through if I cna avoid any weird capacitive coupling between the sides.
Does this audio thing really need an isolated power supply and 6N137 optocouplers for I2S?
Probably not.
Is it going to get them?
Probably yes.
Basically have an ESP32 on one side (let's call it the digital side), and a TAS5805M I2S+DSP+Class-D amplifier on the other (analogish-ish) side.

Neat. Blinker has been a great tool to solve certain problems. Gotta dive in.
A discount version of the Big Lebowski apparently lives in my neighborhood. Just watched a guy with mussed hair, in a bathrobe, walk out to the corner, light a joint, and then wander on down the sidewalk.

Wow. Prepare for it to get even worse very quickly.

2 things: 1) I’m sure cop unions will fight this; 2) all cops are abusive by definition. That’s the whole schtick.
Be right back. Need some nuggets.

Tattoo this on every security person.
Doing my hobbies more efficiently is insulting. That’s not what my hobbies are about.
Otherwise it’s just work you aren’t paid for.
I am very inefficient. That’s the point. I go down random rabbit holes. I have numerous side quests. That’s part of the joy.

Well this can’t possibly go wrong.
I missed this earlier this year.

Me: my LLM escaped containment…
Everytime I listen to most people talk about LLM, it kills brain cells.
You could say that.
It would be wrong.
But you could say it.

Well, there's no worrying sites in... oh.
Oh no.
