a contextual voice note device that one can record a message on and attach to household items. choose priority level to indicate urgency to the other members living in the same house, allowing them to be reminded of chores/tasks.
the team worked on several lo-fi prototypes to decide on the form factor and the primary interactions for the device using a bunch of readily available materials like foam, cups, cardboard, and paper. once we bodystormed and took feedback from mentors and peers, we began working on the technical stuff.
the module we were using to record and playback audio was not fully compatible with the arduino mkr1010 wifi board we were using. hence, we rewrote the module's entire library!
the team quickly designed the outer case and knob for the device. with zero to no experience in fusion 360 and 3d printing, we enjoyed the challenge and completed the first version in just 2 days!
this device does one thing and does it right. recording a note and setting priority are handled by the knob while the different states of the led light communicates the system status.
we used the following components: arduino mkr1010 wifi, dfrobot dfr0745 recorder module, 8w speaker, led neopixel 12 bit, and a rotary encoder.
