SqueezeEsp : The cheaper squeezebox in the world

[bgiraut]

My new squeezebox_esp32 build from a ESP32 chip only and a spdif output. I used an old powerbank with his micro-usb connector as case. I added a 3,3v regulator to power the ESP32
Is it less sexy than the squeezeamp and his PCB but it is cheaper too.



Connected to my ad18 amp via an optical cable

Great bare bone setup!
(I also like the upcycled case)

Now THAT is the cheapest Squeezelite in the world. I'm happy with all the progress we've made since you started the thread.

If anyone's interested, I completed the configuration of a build system. For now, binaries will be available here as releases
https://github.com/sle118/squeezelite-esp32/releases

Note that as we go, there will be unstable binaries. The current stable build would be: stable-WiFi-Manager-squeezelite-esp32-I2S-4MFlash.zip


This allow flashing the software without needing the full espressif toolchain being configured. Espressif's flash tool can be downloaded from here
https://www.espressif.com/en/support...ad/other-tools

Here is a typical download screen


For the ones using Linux, it's possible to flash using esptool.py with a line similar to this:

python /opt/esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x1000 /home/Jenkins/jobs/squeezelite-esp32-SqueezeAmp/workspace/build/bootloader/bootloader.bin 0x10000 /home/Jenkins/jobs/squeezelite-esp32-SqueezeAmp/workspace/build/squeezelite.bin 0x8000 /home/Jenkins/jobs/squeezelite-esp32-SqueezeAmp/workspace/build/partitions.bin

Thanks - you’re in! I might have components for a last one

100% the same here. My solder skills are not the best.
Beatiful would be a kind of package. My dream is 4 pieces, running it with a ac/dc adapter.

I missed this topic, to much work the last weeks :/
Did you have some left?

I would love to organize an europe order point for this project with you guys. Canada is too far away, shipment is expensive.

You will get a pm.

I know there are some good projects to integrate 3rd party voice control to LMS, but just FYI, I saw that today https://www.espressif.com/en/news/ESP-Skainet_Released and I thought it could be a very cool dedicated LMS command system

I think a mycroft support would be nice because it is opensource and had more privacy...

Please note that the discussion on SqueezeAmp has moved to a different thread

https://forums.slimdevices.com/showt...ueezeliteESP32

We can keep discussing more DIY/hacking solutions here. For example the minimalistic spdif device with voltage regulator and spdif connector - that's "The cheaper squeezebox in the world".

I have posted a link to automated builds. Buy a couple of components from your online retailer of choice for its than $10, solder a few connections, flash the binaries and enjoy squeezelite's capabilities and more. We ported squeezelite to the esp32 platform with one major goal: supporting seamless synchronization across players, and philippe_44 was able to fine tune it to a level that surprised us in the end.

Enjoy!

May I recommend a simple writeup with simple to understand drawings (eg from https://fritzing.org/) so Sunday hackers might be able to join the fun?

@philippe, daduke & sle118:
I follow your discussions here and on gitter, but I get a bit confused wrt the capabilities of the current builds:
(And I am sorry to ask this now as you guys are in the middle of development, but I try to build a (bare bone: ESP+DAC) system for a friend which goes in a Tivoli Model One and I need to have 'something' to give to him by the end of the week - afterwards, I can still update the system to a newer version)

1) I tried the binaries sle118 posted here https://1drv.ms/u/s!Ajb4bKPgIRMXmwzK...CHRv_?e=V7Nebj (the 'stable*' version)
That one seems to be currently prone for intermittend dropouts (due to the discussed priority of WiFi manager?); also it misses Airplay, I think?

2) I also compiled the latest version from philippe_44 (refactor_BT/I2C branch); the WiFi manager is included as well and Airplay is available, but Airplay errors out when attempting to play ('no connection possible' on iPhone; on ESP serial I see

this log (Audio via BT):

00:03:16.617498] rtsp_thread:358 got RTSP connection 60

during the error.

Other than that this version (2) seems to run stable w/o noticable dropouts.

Any other hints?

And - do you guys have a very rough idea when 1st OTA testing might be possible?

Great stuff!
Thanks again for your work!

Try to set a specific airplay name by setting, in the cmd line

nvs_set airplay_name str -v « some name »

Did you try from iTunes as well

I set a name, but no change.
I also tried iTunes on my PC; it states its not compatible ...
