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

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 focused on making each interaction as clear as possible. Playing with light & sound in software, experimenting with the form of the knob (knurling, surface), and exploring different materials and colour – all came together as important signifiers to improve affordance.
After getting everything working on a breadboard, we made a compact PCB to fit all the components in our case. For the components, we used an Arduino MKR1010 WiFi, DFrobot DFR0745 recorder module, 8W speaker, led neopixel 12 bit, and a rotary encoder.
