The idea of a light-commutated motor, where solar cells power the individual coils of a motor, was first described by Daryl Chapin in an experiment kit from 1962 about solar energy. [1] The kit was distributed by Bell Labs , where Chapin together with his colleagues Calvin Fuller and Gerald Pearson had invented the modern solar cell eight years ...
The term "electric fluid" was based on the idea that a jar could be filled and refilled when it became empty. [3] That led to the revolutionary idea of "electrical fire" as a type of motion or current flow rather than a type of explosion. [36] Several 18th-century electric terms were derived from his name.

Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.
Newman's Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine . [ 1 ]
An electronic kit is a package of electrical components used to build an electronic device. Generally, kits are composed of electronic components, a circuit diagram (schematic), assembly instructions, and often a printed circuit board (PCB) or another type of prototyping board. There are two types of kits. Some build a single device or system.
