This is a timing device which I’ve made for a symposium in our university.
You adjust the time in the splash screen then press and hold SAY (Count) and it counts up to the adjusted time.
The timer will announce the last minutes of the time by led effects and speech.

From Wikipedia, the free encyclopedia
A velomobile or bicycle car is a human-powered vehicle, enclosed for aerodynamic advantage and protection from weather and collisions. They are virtually always single-passenger vehicles. They are derived from recumbent bicycles and tricycles, with the addition of a full fairing (aerodynamic shell). There are few manufacturers of velomobiles; some are homebuilt. Some models have the operator’s head exposed; this has the advantage of giving the operator unobstructed vision, hearing, and some cooling, with the disadvantage of being more exposed to weather and less aerodynamic.
