i fucking figured it out holy shit y'all
i figured out why the DAC sounded like shit it was because it has this builtin effect called "Stereo Enhancement" and by default it's set to 5 (on a scale of 0-7) and basically it makes the audio sound like actual trash (on decent headphone drivers i guess. perhaps it makes it better for crap headphones idk). anyway you can disable it with

sudo amixer sset 'DAC Stereo Enhancement' 0

HOLY SHIT y'all the audio sounds fuckin normal now

anyhoot (aaa, i should play some acnh again...), gonna work on the rest for now, there's some stuff left to do. need to add some shift registers for the balancers, as the ic can only do internal balancing with a few mA.

i'm looking at the atsamd11 which seems nice? otherwise i could just keep the msp430fr2355 in the schematic, as it is just there already and i like it.

i just don't want to write tons of ic drivers in c anymore when i'd just like to spend my efforts on something more portable.

*funny horsie voice* today, sleepy elen is going to design some electronics.

i'm doing some spite-driven bms development. anyone have a favourite MCU with good documentation, is cheap *and* can be programmed in rust?

Server folks!

I want to deploy a microservice application for AWS initially, and later transition to hosting my own server, what considerations do I need to take into account re: database, service discovery, stuff I haven't thought of?

Boosts deeply appreciated!

Ein spannendes Gespräch mit @ln über open hardware, Sachen mit Strom und viele andere Dinge, von denen ich bestenfalls die Hälfte verstanden habe:

aliexpress, are you ok? and if this is actually a thing, who tf has digital vga!?

tfw you really need a vga to "something more sensible" adapter. good thing we have a small display around in case we need to change bios settings :D

what the errors package is actually missing:
ErrImSorryDave = errors.New("i'm sorry dave, i'm afraid i can't do that")

row-level security combined with session tokens is incredibly powerful for off-loading permission constraints into the database. i'm going to use it for update/delete to model in which cases an action should be allowed :3
