Tenka Inc. manufactures a line of electronic building blocks called Circuit Cubes that inspire kids, age 5 and up, to create fun projects as they become more tech-literate with a basic understanding of circuitry. Only Circuit Cubes with their unique transparent design lets kids see how circuits connect to light an LED, drive a motor, or animate a LEGO-style brick creation. Circuit Cubes can be combined horizontally, vertically, or diagonally for unlimited project designs and endless hours of creative play. Circuit Cubes fully integrate with LEGO-style bricks.
