The course Cardboard Modeling revolved around learning how to model prototypes from foamboard. The models shown here were made of foamboard. The modeling skills of this course turned out to be very useful for low-fidelity prototyping in later projects. Low-fidelity prototyping means to quickly build inexpensive prototypes, allowing you to check design assumptions and easily make changes in the design if necessary.
For the Marble Machine, the assignment was to design a part of a vertical marble track without using glue or tape. I first made sketches of possible features of the piece. Second, I made the separate parts to test if they would work. Then, I combined the working elements into one final part. It was a precision challenge, in which patience and practical insight were continuously required to keep the model working and intact.
For the Coffee Machine I used Arduino in combination with pushbuttons, a potentiometer, a stepper motor, a Servo motor, and a DC motor. The assignment was to make a hot-drinks dispenser with three different types of drinks, and an interaction that is as intuitive as possible. I therefore carefully designed the appearance of the machine and its parts, the order in which actions take place, and the feedback from the machine. These can be seen in the video of the Coffee Machine. I loved to think from a user’s perspective, to let go of the design of contemporary coffee machines, and to make a simple, intuitive, and appealing design.
