Anemometer

September 10, 2013
Today they are talking about weather for the  Jr.FLL topic of Disaster Blaster

and learning about gears.

http://netapps.marshall.edu/lego/lessonplans/Turnstile/Turnstile.html

See how the yellow indicator moves as each "person" walks through?
This gearing counts 4 for one rotation.


Change to the gearing that has a 40 tooth gear meshing with the 8 tooth gear.

Now the indicator is for 20 people.

For the last build
the yellow indicator goes around once when 100 "people" pass.


Add tires as cups to catch the wind.


Wow you are windy.
