Hi Raspiaudio I like your products and your dedication to audio. I think the Muse devices are very unique on the market! I would be very happy to discuss whether you could provide the hardware for a maker project that is popular in Germany.
The project is called espuino and helps to build a music player for children that is controlled with rfid tags. It has good software and documentation. However, the hardware setup is painful. Me, I am struggling to avoid the audio interference coming from the rfid reader via the ground connection.
I am wondering if the ESP board inside the Muse Radio might be the perfect basis for an espuino box. It has all the inputs (button, dial, SD card) and outputs (audio, led) plus the ESP32 S3 should have plenty of free GPIO to connect the RFID reader via SPI.
Would you please share details of the S3 board inside the radio? Is my idea doable?
Can you imagine to sell the board seperately as the IR remote, display, mics and the polished case would not be needed.
I haven’t looked into the details extensively, but I believe this could work straight out of the box with the Muse Luxe by using the existing Grove I2C plug and adapting an I2C RFID reader instead of SPI. The RFID module could be mounted on top of the Luxe casing or even inside, as there is also an internal Grove plug. This would allow for better integration.
This approach is fully DIY, but if you’re planning to produce multiple units, we could explore making a ready-to-use version.
The Muse Radio is also a possibility, but it would require modifications to the PCB.
Additionally, the Muse Proto for makers who want to build custom enclosures.
Feel free to continue the discussion here or reach out via private message.
Hi Olivier,
Thank you, too!
The Luxe came to my mind, first. I agree, it fits the demands. The only caveat is that the project has limited support for i2c readers. Therefore, i decided to ask for the Radio‘s board as it uses the S3 that has more GPIO.
I read from your answer that the Radio‘s board currently does not have pin headers for accessories.
The Proto is also interesting. I just spotted an SD reader on the pictures. I wonder why the specs dont mention it.
One reason is that the popular pcb with RC522 are poorly designed. To allow I2C they need modification. Apart, I think it‘s only software support in the project. This can be improved, I bet.
Ok. Thanks for your opinion on your S3 board.
I believe the Proto is already great. Looking forward to test it, soon.
It’s on the list! we will try to adapt the setting file for the Luxe it seems doable in DIY mode.
And maybe one day if there is enough interest we could make a version of the Luxe with cutom colors for kids and built-in RFID.
