Musical Instrument



As a second-year NCSU School of Design student, Steve Hines designed a one-octave keyboard operated musical instrument.




      Steve created a simple mechanical action using brass tubing, from the hobby shop, flattened to provide a flex hinge, and a rubber pencil eraser hammer.  Hitting the key causes the pencil eraser, in the brass tube, to strike the tuning fork which vibrates the tines.  Electomagnets were made by winding copper wire around simple horse-shoe magnets, and were mounted at the ends of the tuning forks.  When the tuning forks are struck, the tines vibrate and break the electromagnetic pickup’s lines of flux.  This creates an electrical signal which is amplified and heard through the speaker.




      This is not a product for sale.  This project is shown only as an example of past projects.  HinesLab currently offers consulting in the area of industrial design, photographic equipment design, as well as a variety of licensable technology.
