voicetunes VS arduino-esp32

Here’s the solution I built for that, with a combination of on-device voice control, and a Bluetooth remote: https://github.com/lukifer/voicetunes

Something I’d still like to add is a USB OTG emulation of iOS/Android/iPod/etc, so that the currently playing track shows on the dash, steering wheel controls can be used, etc, but my last experimentation a couple years ago didn’t go anywhere. (All the open source stuff for emulating CarPlay and Android Auto seem to be for the other direction: the dash, not the device.)

Offline voice-controlled jukebox using RPi via Mopidy, and just pushed a branch with Mac support via iTunes/Music.app

I can vouch for Rhasspy, it's an amazing and flexible piece of software, though it does require some setup and tech knowledge (albeit with a usable web GUI); and it's very DIY on defining the actual voice commands. I recommend pairing it with Node-RED [0] for routing commands to devices, it has plugins for most things.

The only thing I struggled with was getting the wake-word config right: I could never find the right balance point where it responded every time, without also having annoying false positives, so I ended up turning it off. It does support multiple wake-word engines; I'm gonna have another go with Picovoice Porcupine now that they're opened up custom wake-word training for free.

I'm most heavily experienced with Rhasspy's sister project, voice2json [1], which I used to build a voice-controlled car jukebox [2], and it's been working fantastically. (It triggers from a Bluetooth remote, so no wake-word issues.)

For hardware, Raspberry 3/4 perform quite well, and strong recommend for ReSpeaker [3] for audio (either usb or 4-mic hat).

You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.

Are you perhaps this poster? https://github.com/espressif/arduino-esp32/issues/5250 - asking that poster for the list I just asked for went nowhere and it was auto-closed.

I have 2 ESP32-S2-Saolo-1 's on hand. I am trying to do the example Wifi FTM code that can be found at the following repo: https://github.com/espressif/arduino-esp32/tree/master/libraries/WiFi/examples/FTM

That has not been my experience at all as a user. ESPHome is even easier than Arduino and I haven’t touched firmware code in years.

The price makes a huge difference when you have dozens of them operating which is trivial with a decent hydroponics and smarthome setup. I also have a dozen boards just sitting idle ready to be called up to replace a failed one or use for a new project because they’re so cheap.

Not to mention the Arduino core is supported officially by ESP32: https://github.com/espressif/arduino-esp32

Who actually uses Arduino in production? Everyone just uses modules (for ESP32) or rolls their own using the Arduino board as a reference.

They've done a good job of hiding the RTOS from you and making most sketches run fine without porting, but you're still running as a task under the RTOS, yielding between loop() calls[1]. This leads to mysterious timing issues if you aren't aware of it[2]

It doesn't appear that the Arduino core for the Renesas chip is using the RTOS, at least by default -- its main loop is literally doing while (1) { loop(); }, similar to how the AVR core works. [3, 4]
