This customer wanted to create a low cost talking label for wine bottles. The idea was that by pressing a button the wine bottle will describe itself, and suggest the best wine pairings.
I had less than one month to go from an idea yet to be checked for feasibility to a working prototype that had to be shown in public for an international exhibition. I was able to put up a final prototype that worked, with nylon 3D printed body, rechargeable lithium coin cell battery, and a low cost dedicated IC for the audio samples.
