Abstract: An electrical circuit module easily assembled by hand and especially adapted for use in a circuit package for a model includes an insulator substrate with an upper surface and a plurality of apertures extending through the substrate from the upper surface. A plurality of circuit components on the upper surface of the insulator substrate have leads extending into the apertures. A conductive eyelet extends into each aperture and is dimensioned to form a friction fit with the leads of the components and any additional connecting wires in each aperture. The circuit module may then be mounted in a base including a control panel for an electrical circuit including the module on the base. Light, sound and similar effects are generated by the circuit for a model mounted on the base.

Abstract: A display device such as a model of a blimp has an aperture formed on one side thereof for display of information carried on a screen within the blimp. Means are provided to rotate the screen and to illuminate the screen interior so as to sequentially display the information through the aperture.
