Geolino Technology & Electronics

Behind each door lies a different experiment that can be easily conducted without prior knowledge, using the components and the manual. The focus is on transistors, light-emitting diodes, a light sensor, and a small speaker. This leads to secret light signals, stored energy, light flashes without a battery, LED blinkers, and much more. Included is a detailed manual that explains all the experiments step by step, accompanied by many illustrations. It not only clarifies the individual experiments but also provides a clear insight into how the components work and interact with each other. The playful approach encourages creative engagement with technical questions.
