POV Watch

  • electronics

Description:

The goal of the POV Watch was to find out how to build a completely standalone mobile wearable with the Arduino prototyping platform within a tiny form factor. The main questions being which arduino would be small enough to be integrated in such a project and what kind of battery would provide enough current and still be small. The secondary objective was to find an ambient information channel, as an alternative for the typical screen, that would be available at all times, but never disturb the user by being continuously present.I was inspired by the use of a few simple led's as seen in Violet's Nabaztag and the Ambient orb and how these were used to convey information.

The POV Watch makes use of a technique called persistence of vision where a few leds (light-emitting diode) are placed in a row. These leds flash at a different interval and will form letters when they move fast enough. My idea was that with the POV Watch the user could simply wave a message in the air. Altough the idea worked a little bit, the end it didn't have the desired effect. Altough it sort of worked in the dark, the rapid movement was to tiring to be useful.

In the end the Arduino Mini Pro was chosen, powered by 24,5 mm 3.7v coin cell lithium ion battery.
