A GREAT EDUCATIONAL GIFT!
|
The H-racer is a micro-version of what engineers and scientists have been dreaming about for real cars: combining hydrogen with oxygen to generate a DC current to power an electric motor. Unlike a gas-powered car engine, the
only byproducts of this electrochemical process are electricity, heat and pure water. Recently named as one of the Best Inventions of 2006 by Time Magazine, the H...racer is now the best selling fuel cell product in the world. First step in bringing the
world a tangible vision for a viable hydrogen economy. With the H...racer, you can witness the power of new energy technology in the palm of a child? hand. Unique, patented miniature fuel-cell car and hydrogen refueling station. The Refueling Station
creates hydrogen by electrolysis using water, and once the car's hydrogen tank is full, the car can run on its own hydrogen fuel-cell system, with the simple flip of a switch.

What better way to get students interested in the world of electronics… this AM radio kit offers a world of education plus hands-on experience, with a fine AM Radio as the finished product. These kits were designed to allow
the student to understand the theory behind radio reception, and to allow the student the thrill of building and using his/her own receiver. In this world of mass produced electronics, this kit is a welcome relief.
Features a superheterodyne
receiver circuit with 2 IF stages, AVC, loop antenna, push-pull output stage, 4" wide range speaker and a cabinet that houses the finished radio. Operates on 4 "D" batteries. The circuit uses 6 transistors and since each stage is built and
checked by the student before proceeding, it offers a much better grounding than any kits available today which feature full integrated circuit construction. In this older style, the student actually gains an understanding as to how each stage functions.
These are almost impossible to find, but we found a few hundred of these complete, unassembled kits that were used by many school systems to guide students towards this fascinating field. As these are older kits (but brand new) they could also be thought
of as collector's items… but in reality, their educational value far surpasses their nostalgic qualities. This is an educational bonanza!!!! Cabinet included.
$31.00 Ea/25, $28.00 Ea/50, $25.00 Ea/100, $23.00 Ea/100.
