What have you made?We have made an interactive platform that invites individuals to gather, create and share music. The design leverages on familiar archetypes that people are comfortable with so that the interaction is intuitive and seamless.
What gave you the initial inspiration?The eureka moment sparked when the team was looking at how children were naturally interacting when they were offered a toy with multiple probes centralised within a single built. In this case, it was a box with multiple sticks protruding from the body. As a child interacted with the objects, it triggered a reaction among other children and they were excited to find out more about this mysterious box that was presented. The curiosity element and interplay thus motivated this project.
What is the original idea behind this project?The original idea behind this project came from a drum set where the drum sticks are key to trigger off different audio feedback from the various elements.
How does it work?Hidden within the table are 6 sets of conductive sponges which serve as pressure sensors. As the rope is pulled off one end, the knot on the rope's body presses against the sensor and the pre-recorded tune is released through a set of speakers. Variables are calculated such that with greater pressure, the tunes' pitch and frequency are adjusted (also pre-recorded). This creates variance and invokes interest, As there are 12 different consoles, 12 different pairs of music combination had to be programmed because the music is harmonised when 2 or more sensors are triggered.
How long did it take to make it real?The process of making the product (prototyping the table and coding) took around 1 week.
How did you build it?I The main table is constructed using plywood (18mm) with retro-fitted legs from IKEA.
The speaker panel was made by CNC laser cutting holes on a styrene sheet. The sheet is then fixed over the frame that is attached under the table.
The table top utilises a 2mm thickness silicon piece (RTV 585).
In terms of electronics, the following were used:
- Arduino uno
- MP3 player shield
- Pressure sensor (conductive sponge)
- Analogue speakers
