What Makes It Uncommon

Lights flash, wheels spin, fans whir, and circuits snap together without tangled wires or intimidating tools. Designed to make electronics feel playful and approachable, this hands-on STEM kit lets kids build working creations using magnetic blocks and a wooden pegboard system. Beginners can explore the fundamentals of power flow and motion, while more advanced makers experiment with sensors, timers, RGB lights, and servo motors that react to the world around them. Even better, the two sets connect together to create one giant interactive "Super Lab" packed with possibilities.

  • Magnetic electronic blocks snap together on a wooden pegboard base for mess-free circuit building.
  • The Base set includes beginner-friendly components like LED lights, motorized wheels, a cooling fan, buzzer, dimmer, and switches.
  • The Boost set introduces advanced features including RGB lights, servo motors, light sensors, delay timers, and precision controls.
  • Project guides and concept cards help kids build hands-on experiments and functional creations like desk lamps, flashlights, automatic night lights, and moving machines.
  • Both sets work independently or combine together into a larger system.
  • Requires 3 AAA batteries, not included.
  • Ages 8+.
  • Made in China.
