TransPerformance The Performer The keypad and Liquid Crystal Display (LCD) on this guitar are the obvious tip-off to embedded electronics. A closer look reveals that the bridge and tailpiece are quite different, too. The guitar's six strings pass through a tuner assembly to the back of the guitar where six stepper motors simultaneously adjust each string's tension. The whole system is controlled by a microcontroller, but analog ICs interface to the stepper motors. The motors' speeds are adjustable with full-speed changes of one whole step per second. Touch-up accuracy is ± 2 cents. A cent is a logarithmic unit to measure musical intervals with 1,200 cents equal to one octave.

Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
