In order to help an agile software team to keep time at their 15 minute stand ups, a hand held device was created that beeps after a minute to remind the user to pass it to the next member of the team and let them talk.

It was created using a 3D printer and a series of readily available embedded components. In less then a weeks development time it was used by the team, and after a few prototypes it was refined.
