Wind tunnel out of a Leaf blower hack
Description
So, I Was Challenged To Find The Dead Air Behind An Object. Not That Hard Right? Well, Here'S The Catch, I Can Only Use What I Can Find In Shop Class. Fortunately For Me, There Is A 3D Printer, A Leaf Blower, Some Wood, Spare Vex Parts, And A Digitizer There. All I Needed Now Was A Photogate! I'Ll Explain More Later On. But In Short, What I Am Showing Here Is The Adapter I Made For The Leaf Blower Ensure Equal Fair Flow Across The Wooden Wind Tunnel. In Short, We Have A 3 Axis Arm That Has A Digital Switch (Photogate) Triggered When Air Flows, And When It Goes From Flowing Air To Non Flowing Air It Makes A Point Using The Digitizer ... After A While There Isn'T Any More Dead Air Space, And You Have A 3D Printable Model Of The Dead Air Space. All For Less Than A Spool Of Plastic, $30 Leaf Blower, $5 Photogate, 3 Motors, And A Microscripe (Note You Could Use Encoders If You Wanted To, But We Had The Microscribe And Wanted To Make Our Lives Easy.) Yeah I Never Got Around To Finishing This... Kinda Graduated First And All Of It Was Still In My Highschool.
