As explained in a previous log, design the companion device as a cube made of a single piece turned out to be impractical. Our new approach is to design it in layers.

The first layer is in plexiglass. The partially opaque white material is used to diffuse the light from LEDs placed behind. The face is cut as a pentagon with a laser cutter. In the centre, we have hollowed out a round grid-like window so the speaker can be placed underneath. We have also engraved five icons where the LEDs will be to label each information.

[First try with transparent plexiglass]

Under this plexiglass cover, we are designing layers to hold the components and wiring. For now, we have defined the layers to hold the LEDs and the speaker. Below will probably be the microchip and the Wifi module. Once we have defined if and how we also give visual information on the advice for parents, we will add them to the design.

[Second try, from top to bottom: cover layer in white plexiglass, black paper layer to focus the light, plexiglass layer to hold the LEDs and speakers]

This layered design is mostly for us to iterate. Afterwards, we will probably merge most layers together. We will also have to design a way to keep the layers together.
