Most of these new Cebekit kits require soldering the connections and completing the decorative finishes. They range from a simple kit of a traditional solar mill (C-6142), through the winding and assembly of a basic electric motor (C-6145), to the complex and original kit of a two-story elevator (C-6139) with microswitches, limit switches, contactors, and electronics. These kits          
are ideal for understanding many basic science and technology concepts through hands-on practice. This type of practical learning is truly memorable and doesn't fade away.
