Dear Bloggers,

Year 4 designed, made and programmed fans to operate with a joy stick  controlling the motor speed and direction.  The day was hot so the challenge was  to spin the propeller as fast as possible.  Several very talented boys created compound gear chains to maximise the amount of gearing up  and wow did their fans spin!!  It was really cool – literally.

 

Some clever students made design modifications adding a hand tilt so the fan could also pivot up and down.

 

 

 

Thanks for calling by
