When I was like 12 years old I was given a sort of beginner electronic board that had multiple elements like these connected to small springs. It also brought multiple wires of different lengths and a large book that was filled with tutorials and explanations on how to use it. I remember a specific tutorial that would result in an FM radio, It would have you connect the wires to some of the different things, to a speaker, and to an antenna which could be tuned and such.
Does anyone know what a board like this is called? or where I could buy one?
