The fully working prototype, ready to
be installed in swimmingpools (perfect for both 25 and 50m
pool), is completely waterproof and equipped with 500 led of
5mm each, and it is developed for digital counting of
seconds.
The idea was born from competitions needs of Master swimming
team, with long training experience, in Bologna.
The big display (and the driver dedicated to) has been
tested in different phases where the environmental
conditions have been varied in the range of temperature
25-55°C (77-131 °F) and humidity range 60-100%.
All the circuiting is mounted inside a waterproof cabin
