i think the problem is everyone wants to build “encrypted secure messaging platform” but what i want is “chatroom”

pleased to announce that tangara's design has survived yet another round of "jacqueline sees a cool SoC and questions everything"

it was the allwinner v3s this time. pretty cool little thing! but not actually better for our use case i think

jacqueline,

the main thing you need to know to understand why it’s not a good fit is that i consider this, our current cold boot time, to be fairly slow

i turn on a tangara. after something like 2-3 seconds, a splash screen appears. after another 2ish seconds, the main menu

jacqueline,

that's like... 2-3 seconds from power on, to our firmware running (showing the splash screen is the first thing we do)

then a couple more seconds to have an actually usable device (we can improve that second gap i think; haven't looked much into it yet)

the number one issue with 'more powerful' SoCs people have yelled at me is that most of them are still fucking around in u-boot or whatever by this point.

our esp32 boots fast enough that, when you're not actively using your device, we can just turn the whole thing off. so long as we restore your playlist and such when we boot back up, it's fine. it's not too annoying.

if your boot time is... what, 10 seconds? 20? then at some point you cross the "this is really annoying" threshold, and you can't do that anymore.

anyway. my point is, tangara is supposed to play music conveniently. the esp32 is good enough to play music conveniently.

are there cheaper/better/faster/stronger SoCs? i guess. are they 'better' in ways that make them more convenient for playing music? not necessarily!

people kept asking why our boot time was slow so i made it faster

Rewatched 2021 Dune. This film is so much better than what I remembered. I wish it had a sequel… 👀

i love when datasheets are like

"This is a 1V8 voltage regulator.

Suggested applications:

  • Devices requiring 1V8 voltage regulation"

no centralised social network could ever produce "the taliban deleted my account". that's a mastodon special.

performance is a bit rough rn, but there's a ton of areas i know i can optimise. with that caveat...

i now have my esp32 decoding opus from an sd card, resampling down to 44.1kHz, re-encoding into SBC, and streaming to a speaker. whilst also updating ui (the ui is implemented in lua and has databinding support)

the thing i think people need to understand about modern microcontrollers is that they're really fucking fast
