Lecteur audio intelligent Ambi'Son micro

Lecteur audio intelligent Ambi'Son micro, photo 2

This small and affordable device is a standalone audio file player using a micro-SD card. It features a processor capable of making playback "intelligent" — that’s what makes it the Ambi'Son!

For simple use:

At startup, it plays all files randomly, endlessly
A short press on the push button (< 5 seconds) triggers one random file playback
A long press on the push button (> 5 seconds) triggers all files in order, endlessly

It’s ideal for creating an audio kiosk, a sound installation, a museum display, a stage setup, integrating into a work of art, or for model railroading, for example.

For advanced use, read the user manual.

If you're looking for a simpler and even more affordable module, check out my "Exposi'Son". Need help choosing between the two?

A sound box.
Etc.

All kinds of projects are possible, so if you want to explore feasibility, contact me.

Details

You'll need to equip it and possibly build a small enclosure yourself, but make sure NOTHING conductive touches the circuit board. There's a risk of fatal short circuit to the module!

I fully designed the device — from the PCB layout to soldering the components and programming. It is handmade.

The module alone is very energy-efficient. On rare occasions, so-called “smart” power banks may shut off, cutting power — especially at low audio levels.

If you have any questions, suggestions or issues, contact me.
