Prototyping

To make this concept to a reality, we set to implementing the features into an arduino driven prototype housed in a 3D printed casing. Through developing a wiiring schematic, coding, CAD modeling, printing and assembling.

Extent of the prototype

Given the technical complexity of our concept and the time and material restraints for this phase, we decided to go for a partial prototype. It would consist of the remote and one speaker, as a proof of concept, and the scale would be slightly bigger than the final version, to accomodate for the arduino boards and extra wiring. Because the double language setting would require an extra recording board and more space inside the casings to accomodate it, we reduced the languages in this prototype to one.

Electronics

Combining an arduino nano with RF emmiters and senders, LED's, buttons, speakers and a recording module we were able to achieve all the capabilities our final product would have.

Coding

The arduino was coded using C++. It comunicates with all the other components and with the other arduino via the RF emmitters and recievers.

3D printing

The casings for both parts of the prototype were 3D printed, which allowed us to create complex geometry and adapt quickly. We made 2 versions: the real shape(shown in the picture) and one adapted to fit our electronics.

Foam

The handle on the remote was made out of foam. It keeps the prototype closed, but can be slid off to access the electronics and the batteries. Carving the foam provided perfect fit and a smooth soft surface to hold.
