The Pentiductor is a Hands-on, interactive learning exhibit which can be used by more than one person at a time.

By touching the center disk with one hand and then touching any small disk with your remaining hand, a sound is emitted. If more than one person uses the exhibit at a time, the tone will deepen with each additional person.
When you hear a sound you are conducting  a small  amount  of  electricity through your body to turn on an oscillator, which produces the sound.

How it works:  A small electrical signal  is sent to the disks and is conducted through your body. The electrical signal is derived from a solar panel in the exhibit, so the signal is totally isolated from the AC power source. By touching the large center disk and any of the small disks you become the wire that completes the circuit allowing the signal to turn on a synthesizer. More users increase the conduction of the signal which adds more charge to the signal, which in turn produces lower tones. Touch circuit technology will someday replace many of the mechanical switches currently in use, as mechanical switches are prone to break downs due to dirt contamination and wear.

Hands-on Interactive Exhibits

As more people touch the plates, the sounds develop deep tonal qualities that are reminiscent of musical notes. It illustrates touch switch technology, electrical conductance &  oscillator theory. Plus, it's a lot of fun.

The exhibit is at our Montana Science Center, located within the
Poplar Middle School, Poplar Montana and was provided by:

MRISAR - Institute of Science, Art & Robotics
