“This incredible machine was built as a collaborative effort between the Robert M. Trammell Music Conservatory and the Sharon Wick School of Engineering at the University of Iowa. Amazingly, 97% of the machine’s components came from John Deere Industries and Irrigation Equipment of Bancroft Iowa, yes farm equipment.
It took the team a combined 13,029 hours (6.26 years) of set-up, alignment,calibration, and tuning before filming this video…
It is now on display in the Matthew Gerhard Alumni Hall at the University and is already slated to be donated to the Smithsonian.”
