Arm your house with sensors and a burglar alarm! Make an escape through an electronic trapdoor! Wire up an elevator, electronic drawbridge, and house-to-house tramway! This cool construction kit lets you design houses with lights, sensors, sounds, and moving parts. With a combination of construction pieces and electronic circuitry components, Archi-TECH Electronic Smart House teaches creative engineering and technology in a whole new way.With over 70 building components, this kit allows aspiring architects and engineers to design and build single and multi-story structures, including container homes and tiny houses. But building the structure is just the beginning. Plug-in power posts and electronic components let you “wire up” your creations with lights, alarms, and sensors so you can add a trapdoor, elevator, gondola, moving staircase, and more!
