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.

As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
