Here a brief explanation of the ESPMuse project. Based on the question of Stephan on of the first early bird to pre-order the speaker.
What do you have in mind with this ESP32 ESPMuse speakers?
See these speakers as an affordable daily usable device where so you can virtually implement any protocol or existing project for ESP32. Our vision is to have some kind of app store where you can upload any app to your speaker from a standard bluetooth speaker, a babyphone, a dedicated skype like device.
Unlike some other development platforms we want it to be usable everyday, visually pleasant and affordable.
Does it have some sort of multiroom protocol (like sonos, but open source) or do you know about any open source solution? Does it support bluetooth only or is it planned to have a client for wifi webradio streaming?
To make your life easy we will deliver the ESPMUSE with Squeezlite preloaded on it; it supports Regular bluetooth AD2P, Airplay, Logitech media server. The 2 last protocols mentioned supports multi room protocol.
Also for educational/fun purposes we will provide our arduino code for a standard bluetooth speaker, so you can modify anything you want like the annoying prerecorder “bluetooth connected” that is so annoying on cheap speakers.
- What is the exact function of the microphones? Do they work like headphones for a mobile device?- Does it support alexa connections or even some open source solution as a smart speaker?
On board microphones are for future usage, such as vocal assistants like Alexa or some open source initiative. I haven’t look at it yet
When will it be ready to ship?
Shipping now
What will I receive ?
Happy to share the unboxing :
Here is a little update on the Muse Light and Luxe.
Both PCBa are ready and functional, but we had trouble with the factory manufacturing the plastic shell and doing the assembly as they have drastically modified their terms and conditions by requiring a huge MOQ of 2000 pieces…
BUT, I have found a new supplier and it is going to be even better looking, sharing a faw picture of our 3Ds:
ESP32 programmable via micro USB (usb to serial built-in)
2x5W Stereo
1 onboard mems microphone
3 buttons
18650 rechargeable battery with level sensor
Stereo 3.5mm LINE jack input
1 grove extension port
1 programmable RGB led
I removed one microphone as this cas does not have 2 holes for the microphone, I also have no backlighted button but one RGB led that can be seen from the top.
Now targeting mid of February for first units shipping. For existing backers remember that you can retract at any time and ask for a refund.
Happy to share the unboxing of ESP MUSE LUXE speaker number 1:
So everything works great and we could start production next week !
I can give the “GO” for the PCBa factories and the assembly factory. It should take a month for the first batch to be ready to ship out in Europe for pre-orders
Updates—
The assembled and tested PCB are in our partner factory for the assembly inside the speaker casing. The assembly will be finished on the December 18th 2021 and some units will be shipped by air for the backers. With the high season it should arrive on the 27/12/21. Then we need to check them and upload a new firmware to send it to you.
Backers should receive their units first week of January 2022
This port uses signals for I2C bus so it could be used for all kinds of peripherals such as screen, touch sensor, humidity, temperature… Limit is your imagination! We encourage you to create crazy applications fo the Muse, let us know if we could help.
So a grove port is a defacto standard brought by Seeds Studio but in fact this is just a fancy name for a standard 4pin PH 2.0mm plug
So if you want something already made you can just buy this screen and this should be plug and play (not tested but the pinout matches)
But if you want to use this very cheap and widely available screen search for “oled screen” here we are using a 1.3" model**. Check the pins order as it should be GND VCC SCL SDA** some manufacturer invert some pins, careful as it could damages the screen if plug incorrectly.
Then you need a cable to go from the GROVE 2mm pitch to the 2.54mm pitch screen pins, I recommand this premade cable
Then match the pinout of the cable with the port of the LUXE.
Regarding the casing we have made a 3D printable casing something quickly that could certainly be improved. It clips on the edges of the LUXE. But for now this version still have an hanging cable, idealy I would like to change it with some kind of conduit for the cable.
For the software, we have modified the internet radio projectt to support the screen you can flash the bin file Radio_screen or recompile the code.
This is also possible to use the screen in Squeezelite in the web configuration menus select SD0 18 and SCL 23 for the display choose the correct driver, for us SH1106.
I bought the cable and the screen and setting up gpio pins (SDA18 y SCL23), driver (sh1106) and width and height (128x64), but unfortunately no signs of life in the screen.
I tried with different cables with no change in result.
How can I know if the screen is not a failed one?
I am not sure why, but now the screen is working.
Only thing I can not do is rotate 180 degrees, it is not work in the hardware page nor NVS editor.
Is it possible rotate the screen?
My muse Luxe behaves strangely since today… don’t know if it’s related to the last Music Assistant version or ESPhome firmware… but now when playing a music, it starts 1 min then stop with some glitches noise… keep silent 30-40s, then resume playing around 3-4s… and so on (silent 30-40s/plays 3-4s)… so completly useless
While being stop, I checked the log of ESPhome, it’s still receiving well the event (mute, sound level, play, etc…)… Maybe comes from the builtin battery. So here are my questions
i) from the USB cable, is the ESP32 directly powered or it pass through a the battery charger system ?
ii) Is there a way to open the box without breaking the warranty ?
Hi, Have you tried to let it charge for something like 30mn while the power switch in OFF position, then start it again. Do you still have the issue?
If yes try a different USB power supply, do you still have the issue?
thx
Yes I tried to wait few hours (power off) and with different USB cable…
Important detail, when the music is freezing, I can change the song and it resume to play immediatly. Also radio seems to not suffer from these glitches. So seems to be MA related… but I can’t yet discard completly the battery problem. I saw to the video how to disassemble the luxe model … so in the worst case, I can try with a new 18650. Does the electronic integrate a battery protection ? Is-it possible to read the Vin from an ADC GPIO ?
It does not sounds like a hardware issue. And while being plugged the power supply comes from the USB.
A way to prove it is to upload a different software into your Luxe and check if this is working fine.
