Janek's Computers

iOS and Android app

• nice setup experience
• connect to the right pi
• authorize Spotify
• then show the homeassistant interface

App interface

• checkpoint goals
• any sveltekit PWA
• areyourunning comms
• volume fader

• from Leo’s perspective
• she’s normally using the hardware module
• she might want the app

• from Janek’s perspective
• uses iOS/macOS shortcuts and kind of loves it, but not everything is exposed and there are annoyances
• needs access to settings like volume and max fade vol

• from Dave’s perspective
• suggested PWA
• HomeAssistant compatibility

• general ideas
• maybe the raspi server exposes what endpoints/settings it has, and the app reads and displays that?

• example settings
• fade lenghts
• final volume of alarm clock
• current music volume

Tasks

• playing files from the web, iterate over a folder
• a little open - if we pass it a radio stream, it would not need extra work on esp side
pros cons
Pro
• would ease the requirements on the alarm clock
• would be a nice contribution from me
• would be a continuation of the youtube stream project
• with the added complication of DL’ing the tracks automatically
Con
• would have to run somewhere (what’s the hosting/server? maybe it even goes over usage limits)
• is it going to be stable enough?
• 1: play like any other url
• where do the files live:
• 2: listen for a signal/callback when it ends
• later: maybe randomize

• web interface checks
• “esp32 http server”
• serve any index.html
• take input
• take input and save it to disk permanently

• wifimanager

Alarmfiles + voicedrop

• server side
• can drop files into an s3 bucket
• can send VMs that are later dropped into the s3 bucket
• maybe add an endpoint “list” that lists s3 files? would be easy
• on the other hand, listfilesis possible on the bucket itself
• but getting a “address” of bucket and “list” endpoints would be quite convenient
• different playlists would be great
• spotify? youtube?

• alarm side
• run code on esp
• be able to read debugs from esp
• add callback in code to print when something is played
• then ideally when stops playing and we’re good
• add the possibility to list files from s3 bucket
• can it play oga? otherwise need to convert <eyeroll> - maybe amazon mediaconvert would make it ok
• checked as well as possible for now
• play any file from S3
• list files from folder, detect when they end and play the next one
• support different subfolders
• limit to specific extension

• bot
• deploy - make a new branch, make it a fresh deno project, deploy

Codebase intro

Overview

main.cpp functions

15.09

• lq nts finden?

• welche raspis gibts und kosten?

Costs

• main module:
• 20eur alles

• light:
• elektronik 20eur
• lichter selbst 10eur

• kaffee:
• elektrisches bialetti: 55eur
• elektronik: 15eur

• musik:
• esp32 version: 20eur
• zero w version: 20eur + 5eur
• rpi3: 40-60eur
• rpi 70-90eur
• billiges soundsystem: (nachschauen, aber ~30eur)

Decisions

• esp32 vs rpi for music module
• we want nts! can’t find lq audio for it

• do we need a web interface

• this is a “spotify playlist to online radio”, which is a submodule of svt youtube stream!
• with extra steps but maybe it’s good :)

• probably need to send signals to the azuracast server to play/pause
• I think it has webhooks which is good
