Lectron Microscope (EI)
Lectron was a modular electronic experimentation kit designed to introduce youth to basic electronic circuits and theory. Description The Lectron kit consisted of electronic components installed within individual "building blocks" with a clear plastic base, an opaque white top with the component's schematic symbol and permanent magnets attached to the leads of the enclosed components. Each building block was magnetically attached to a metal plate serving both as a work surface and ground (electrical), ground, eliminating the need for soldering, spring terminals or a breadboard. This gave the benefit of safety as well as the ability to rearrange the blocks to determine the effect on the circuit. The instruction manual gave instruction on the proper arrangement of the blocks as well as the function of each individual component's contribution to the final circuit. Experiments began with simple circuits such as a basic electric lamp circuit with switch and worked its way to a three ...
