Pentiductor

Directions: This exhibit can be used by more then one person at a time. Touch the big disk with one hand and then touch any small disk with your remaining hand. If more than one person uses this 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 from a battery 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, which is illuminated by a florescent fixture, so the signal is totally isolated from the AC power source. By touching the large 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.

A touch sensitive oscillator. This exhibit has been tested with thousands of students across mid Michigan with great response. It is light weight, easy to use and durable. The five sided design makes it adaptable to fill inner floor spaces. To use the Pentiductor ,students touch the center metal plate with one hand & one of the small outer plates with the other hand at the same time. The device conducts a small electrical signal which turns on an oscillator which creates sounds. As more students touch the plates the sounds develop deep tonal qualities that are reminiscent of musical notes. It is extremely fun to use & illustrates touch switch technology, electrical conductance & oscillator theory. The exhibit operates on a totally isolated power supply at approx. 6 VDC. Requires grounded 120 V AC outlet. A Solar powered version is available at no additional cost. The text supplied on the exhibit discusses the theory & applications. The exhibit is available in a wide variety of colors. Price $2,500.oo US plus shipping & crating. Please allow 8 weeks for fabrication & delivery.
A grander version of this is the Touch Spectrum, which allows incorporates super bright LED's that respond to the touch plates as well.
