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 Wire

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.

Build A Simple Curie Effect Magnetic Heat Engine

This article shows how to build a simple Curie effect magnetic heat engine. The heat engine uses a special high nickel content wire that has a low Curie temperature.

UFO Detector

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.

Fuel Cell Car Kit MFC-02

Intelligent Fuel Cell Car automatically turns when the car hits a barrier.

The Car Kit Manual includes experiments and background information to help you explore the history and future of emerging fuel cell technology. Use the Reversible Fuel Cell to safely produce hydrogen. Then watch your car run on energy from water.

Fuel Cell Car Kit MFC-01

With this unique kit, you can build your own experimental reversible fuel cell car to learn more about this energy source. With more than 30 experiments and demonstrations, users will learn how a reversible fuel cell works to perform electrolysis as well as to create energy.

Robotic Arm

The Robotic Arm teaches basic robotic principles. Using the servomotor controller one can control the arm to grab, lift, lower, wrist move and pivot. The PIC16F873 micro controller used in the servomotor controller will be freely updated for one year to incorporate the Windows PC program and speech recognition hardware scheduled for release in November 2004.

Geiger Counters: Digital, Analog, Meter, Kits and Assembled

Geiger counter are useful for checking for radioactivity and performing nuclear experiments. We offer eight models of Geiger Counters to choose from. Two Geiger Counters models are available in kit form. We also sell components for making your own geiger counter like GM tubes and radioactive sources.

The Ecosphere

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.

Kirlian Photography

The Model 3 has all photography functions on the front panel. These include the on/off power switch, discharge switch, frequency control and discharge plate. This device is designed to work with all 4" X 5" color, b/w 4" X 5" sheet film and paper. In addition polaroid film may also be used with this device.

Kirlian accessories and information.

Superconductors & Dewar Flasks

Due to high demand, all superconductor kits are on backorder. Delivery is 6-8 weeks. Sorry for any inconvenience.

Demonstrate the Meissner Effect, flux pinning, and low friction magnetic bearing with our super conductor kits. Our Dewar is constructed out of borosilicate glass, specially designed to hold liquid nitrogen.

Additional information and options for superconductors.

Solar Engine Kit

The Solar engine kit stores electrical power from the sun. When enough power is stored the circuit dumps the stored electrical power through circuit load, in this case a motor. This kit may also be used with BEAM style robots or a solar roller.
