{"product_id":"der-grosse-elektro-workshop","title":"The Great Electrical Workshop","description":"Alternating current, voltage and electromagnetism - in over 130 experiments, children aged 10 to 14 explore the world of electronics. The simple plug-in system allows numerous circuits to be built, clearly conveying fundamental knowledge. Through series of experiments in individual electrical projects, children discover, for example, how light meters, alarm systems and twilight switches work with electrical sensors and learn the basics of digital technology using transistors and a timer. Special highlight: the AC generator. In a total of 12 chapters, the comprehensive instruction booklet clearly explains all circuits and conveys important fundamentals and background knowledge.
