The interns Leonora and Petz now focus on the NightReader. They have another two weeks to go and want to get this design job done. They plan to use their experiences with this design in the presentation they are expected to deliver at their school. However it is still not clear how a number of problems should be solved.
Leonora and Petz discovered two fundamental new approaches for the construction of the box that houses the three batteries of the NightReader. Both ideas help to make the instruction package to make the NightReader thin enough to be sent to users by post in an envelope.
One is to link all parts of the box -if sheet metal is used- with a hinge-like construction so that is is completely collapsible. We have still to explore the possibilities this method offers.
The other approach does away with sheet metal. It makes the box from two layers of cloth, sewn into rectangles made stiff with inserted bits of carton. This approach is promising: easy to make on a sewing machine, looks nice, easy to decorate. But as yet there is no answer to how a number of parts will be joined.
I trust that the continuing experiments, by the two girls, in our sunny garden will provide that answer.
