We've seen some great electronic design tools for kids come and go. LightUp is a new one that uses magnetic components to create circuits that literally stick together. That is great, but we've seen it before. What LightUp brings that is new and quite clever is an augmented reality interface that allows the user to point a smart phone at the circuit and see animated "electrons" move around on their circuit to understand the flow of electricity. Using the phone's camera and a little bit of augmented reality magic, the app can analyze the circuit and identify problems or illustrate the flow of electricity. It looks very impressive tool to visualize and debug designs. LightUp is a KickStarter that is doing quite well so far. Take a look at the video below to see it in action.
