Ada & Zangemann
The famous inventor Zangemann lives in a huge villa high above the city, constantly building and programming cool gadgets that everyone can’t wait to buy. But one day on a walk through town, something happens that changes the way he sees his own inventions—young people are using them in fun ways, and that make him furious. As Zangemann begins controlling all of the world’s computerized devices to do exactly what he wants, a young hardware tinkerer named Ada learns that the power of computer code can set her and children everywhere free from the villainous inventor’s selfish plan. Through clever experiments with hardware and software, Ada and her friends show the world how important it is to be able to have control over the everyday technologies we use. For readers ages 6 to 106, Ada & Zangemann will arouse children's interest in tinkering with hardware and software, and encourage their desire to shape their own technology.
