Speech Recognition Kits
Our Speech Recognition Kit performs speech recognition independently in a stand alone mode, or it can function as a slave to a host processor in CPU mode. In stand alone mode, the circuit can recognize up to 40 words lasting one second each.

Nitinol is a shape memory alloy actuator wires. Its operation resembles that of a muscle; it contracts when heated. Many times an electric current is passed though the wire to heat (ohmic heating) the wire to its transition temperature. When the electric current is removed, it cools and can easily be stretched back it its original length. Nitinol wire is sold in five standard diameters; .006, .008, .010, .012 and .015 dia. Priced provide is per linear foot.

Magnets affect materials in one of three ways, attraction, non-attraction (neutral) and repulsion. Diamagnetism refers to an objects weak repulsion from an magnetic field. There are no poles connected with diamagnetism. The north pole of a magnet repels the material just as well as the south pole. Just like a north pole of a magnet will attract iron just as well as the south pole. Graphite is diamagnetic. Pyrolytic graphite is 10000X more diamagnet than most common diamagnetic materials such as water. Thin slices of pyrolytic graphite are extremely light and can be made to levitate. The closest thing to a perfect diamagnetic material is a superconductor however superconductors still require liquid nitrogen to become superconductive. Whereas pyrolytic graphite can levitate at room temperature.
LEV-01 Kit includes (4) neodymium magnets, (1) steel base plate (1" x 1" x .036 " thick), (1) Plastic Dome and (1) Pyrolytic Graphite.
Many UFO's cause local magnetic and electromagnetic anomalies. The UFO Detector senses these anomalies and signals their presence by flashing an LED and beeping. Many UFO's cause local magnetic and electromagnetic anomalies.

The EcoSphere is the world's first totally enclosed ecosystem - a completely self-contained and self-sustaining miniature world encased in glass. Other sizes available.
The Model 5 includes an adjustable high voltage power supply, Transparent Discharge Plate (TDP) and Ground Plate (GP). The high voltage power supply top panel controls include the on/off power switch, discharge switch, Hi-Low frequency switch and variable frequency control.
The Transparent Discharge Plate (TDP)allows you to shoot kirlian photographs using standard digital cameras, film and video (low light). The black Gorund Plate (GP) makes it easier to ground inanimate objects.
