Look at any circuit diagram and you’ll see a bunch of lines connecting a bunch of blocks, a simple but useful illustration brought ingeniously to life by Pai Technology’s Circuit Conductor kit. It comes with 12 different electrical function blocks, from a lights to a speaker to a miniature fan, and six easy-to-connect wires to connect them. Kids can use an impressive companion app to build basic and parallel circuit setups as well as connect the components to make their own creations which they can then scan into the app to see how the electricity is flowing through them in real time.
