Study Ball by Emilio Alarcón

How many times have you begun to study for an exam and after 15 minutes get distracted and move on to doing something else. The Study Ball is a prison-style ball and chain that you can program to keep track of how much time you spend studying. Once you’ve selected the desired duration, you chain the ball to your ankle and the manacle won’t come off until the schedule study time is up.
A red LED indicator displays the “Study Time Left” and keeps you informed as to how much longer you’ve got to keep studying.
