Leave voice notes for friends around the house

Course: tangible user interfaces
Mentors: Massimo Banzi, Pierluigi Dalla Rosa
Team: Vedant, Gahan, Rohan




A contextual voice-note device that attaches to household objects. When placed near an item (e.g., the fridge), it plays reminders—helping housemates remember chores, tasks, or shopping needs in a non-intrusive way. 



We worked on this from ideation to a functional prototype in ~10 days. The team wrote a library for the DF-Robot component used for audio functions. There were several iterations on the each part of the product, like the knurling and shape of the knob and the 
case itself.


We CAD modelled the case and various knobs to explore the best form and tactile feel, we also explored several lighting patterns and made custom sounds for each state in Logic Pro.



After getting everything working on a breadboard, we made a compact PCB to fit all the components in our case.
