Raytheon Lectron modular electronic experimentation kit

The Raytheon Lectron was an educational toy designed to teach basic electronic circuits and theory to young individuals. The kit consisted of electronic components within building blocks with magnets for easy assembly on a metal plate, eliminating the need for soldering. The instruction manual guided users through various circuit experiments, starting from simple setups to more complex configurations like a three-transistor radio. Originally invented in the 1960s by Georg Greger, the product was manufactured in Frankfurt, Germany, and sold worldwide until 2021. In North America, Raytheon marketed the Lectron under different versions, such as "Electronic Dominoes" and "Lectron," offering various sets and add-on kits for circuit exploration. The history of Lectron involves licensing agreements, design changes, and the evolution of the product line over the years. The business was eventually donated to a not-for-profit organization in 2001, ensuring its continued development.
