Hi! Considering that the media player functionality appeared in the project (thanks to @outer meteor ), I designed and assembled such a mini-player for ESPHome. It's soldered directly to my 4ohm 3w old soviet speaker.
Also, I have so far partially ported the GME (Game Music Emulator) library, but it already works fine with NSF (Nintendo NES) and GBS (Nintendo Gameboy) formats. I wrote my draft component, which recognizes the URL and can switch tracks in these files by the fragment (#) in URL.

Awesome! Just out of curiosity what software did you use to design the on-board antenna?

Awesome! Just out of curiosity what software did you use to design the on-board ...
This antenna is copied from one of the 2.4GHz ESP8266 modules. ESP32PICO-D4 does not require external radio components, the main thing is that the waveguide should be 50 ohm, and this is easy to calculate, for example, using a calculator in KiCad. The connection with the access point is stable, the signal strength is normal. I use this method already in several of my devices - they all work fine.

Oooh nice! Thanks for the info 😄 what's the audio amplifier that you used?

Cool @stuck carbon now only a mic and battery charger on it and i could use it for my CommBatch project .

this is exceptionally cool! nice work mate.

I mend to say that to @flint bobcat off-course, my mistake

@flint bobcat great project. Is this going to be shared?

Looks amazing, and it seems the sound quality isn't bad at all, right?

<@760700525376307210> great project. Is this going to be shared?
Yes, I'm going to make the project open.

Yes, the sound quality is good enough for me. But you need to understand that this is a class D amplifier with all the advantages and disadvantages. I didn't use any output filters, so the distortion caused by PWM is still felt at high frequencies.

@flint bobcat do you think this can be used as a multi room audio system?
flint bobcat
I have not studied this issue. If there are software components with the necessary support, then of course you can use it.

I think that ESPHome has some new features for that

@flint bobcat have you seen the M5ATOM echo. man that is a really small device.

It has very little power output.

As far as I know ESPHOME does not have this functionality. Only MP3 playback from http stream.

This looks really cool. Are you going to sell these?

@flint bobcat Congratulations
Great project. I would be very grateful if you could share the project with us. 😄

Which should be enough for music assistant to use them right?

Hey @flint bobcat , do you have the files for the board somewhere?
If you're not selling them, I'd like to order some pcbs myself to try it out 🙂
flint bobcat
I wanted to publish on github, but there is no time, and what apathy because of recent events. No creativity at all...
So let it stay here for now. Maybe someone will be useful.

thanks @flint bobcat for sharing the files... in which format they are? I'm using EasyEDA and I've tried to import it as Kicad files but doesn't seem to work
flint bobcat

The project is made in KiCad. I will not upload the source files here, I will leave it for the github. I posted an archive with gerber files for ordering boards in jlcpcb, as well as all related files for soldering. I even attached layered pictures of the board in pdf format.

Hoi @flint bobcat, i'm trying setup my own PCB based on you schema and i want to replace the antenna with a 3D version like the ESP32-PICO-KIT, adding adding a battery wireless charging and a i2s mic. I do see that you are using a different power circuit then i have seen on other schema's did you design it your self or did you pick it up from somewhere else? And how is that working out?
Also i have been looking at Github to see of i could find the KiCad files so i could import some of the work you already made. But maybe i looked at the wrong dudanov over there or did you not published it ?

Do I understand correctly that installing an ESPHome device on an esp32 via legacy vs modern method is basically:
1- Legacy uses esphome flasher, etc and modern uses the web based installation but the end result is the same for both?
2- Or is there a preferred method for some reason?
Thanks.

My understanding it that the "modern" format is an all-in-one package for serial flashing starting at 0. The "legacy" format is used for updates using OTA or the device web server.
@outer meteor is that correct?
outer meteor
Correct
Modern includes the bootloader and other partitions.
Legacy is only the application partition

esphome flasher is deprecated and only works for 8266 and original 32, no variants.
tacit karma
So I assume that -modern- is best because it includes the bootloader etc.?
graceful ore
Only if you're serial flashing.
tacit karma
Great information. Thanks.
outer meteor
I need to update the ota and webserver code so they accept but only actually flash from 0x10000 of the file

Super cool, sounds good too

Is it feasible to modify this to do 25 watts for a dayton audio thruster speaker?
Cool idea you had here and as a complete noobie here this might be a cool way to drive something ive been working on with the wifey

I guess this one might work https://www.audiophonics.fr/en/exciters/dayton-audio-daex19ct-4-speaker-driver-exciter-5w-4-ohm-o19mm-p-14884.html but I was hoping for the thruster model for more base.
