Build an analogue Pomodoro Timer with Arduino
Many people around the world use the "Pomodoro" time management technique at work, which is said to increase efficiency. From Wikipedia:
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The technique uses a timer to break down work into intervals, traditionally 25 minutes in length, separated by short breaks. Each interval is known as a pomodoro, from the Italian word for 'tomato', after the tomato-shaped kitchen timer that Cirillo used as a university student
And now the technique has made inroads to the maker community, as various people make their own Pomodoro timers - such as the excellent example described by John Boran Jr.
John has used three stepper motors to control analog rotary dials, each of which rotate to indicate which stage of the working period is current - and then rotate them all in an anti-clockwise direction upon the end of the period. This is demonstrated in the video below:
We really love the enclosure, it could be classed as retro, or futuristic. What do you think? Anyhow, making your own is simpler than you would normally imagine, so visit John's instructable page for all the details.
