This was a group project for a course called “Interactive technology design” in which we chose a theme, in our case “Traces of use”, combined with a secondary theme “Time”. The purpose was to create prototypes and iterate them by testing them according to interaction qualities such as “calm and gentle”.
From the start, we wanted to create a time piece that would display time with different modes: vague, half-way and precise. From the clock prototype we evolved to a second prototype and finally to the one below which I modeled in Solidworks with working gears to be 3D printed.
The casing was mostly wood that was turned to create rings around the 3D printed parts. The copper ring is right on the gear and can be turned to “wind” the watch and show a more accurate time. It was connected to a 360 servo to detect when it was being turned so the light under the minutes could be lit up and the minute hand could pop out to show the exact time.The bronze plates at the top were laser cut and connected to an Arduino connected outside of the watch with the batteries.
The bronze plates sent a signal to set a quarter break (in blue) in the hour to plan a pause. When the time comes for the break, it starts gently vibrating.
The actual proportions of the watch we envisioned can be seen on the third image above.
The following movie, which I filmed and edited, was to be used during an exhibit at TU Delft to showcase our working prototype.
