Testing of RFID, Raspberry Pi and music

After a little bit of discussion, we ended up going for the first prototype. Although the second prototype had one clear purpose, it would probably have ended up too complex and less intuitive than the first idea. We decided to keep on working with the materials and increase their importance.


This week we started testing the technology we are planning to use. Firstly we had to figure out how to track the cubes in the sliders of the mixing table. For this, the best option was using RFID chips and readers. We implemented them in our Wizard of Oz prototype by placing one RFID tag in the cube and three RFID readers under one of the sliders. In each part of the slider the cube will activate a different sound. For now we are using buzzers to illustrate and test our concept. The buzzers will most definitely not be used in our following prototypes . We have also acquired a Raspberry Pi and installed drivers to connect the Arduinos. We made our first purchase; a micro SD-card for the Raspberry.





Secondly we had to test the music and sounds we were planning on using. For this we thought on how the music could represent the different physical properties of the materials and we started to explore different instruments and sounds. The plan is to have three elements; rhythm, base or chords and melody. These will change in some way when the cube changes place in the sliders. This will permit the user to experiment with the different qualities and make their own little composition.

Report from Rockheim

When our model arrived at Rockheim, the stage was set for the world to witness SoundCubed. At first we were having rather major issues with the RFID sensor, who decided to take the day off on Sunday. We were therefore somewhat worried that this would continue on Monday. Luckily it didn’t... The model worked rather flawlessly, and we quickly forgave the unfortunate behaviour of the past day. In terms of feedback from the audience, it was very positive. Not only did those who try it say it was cool, it also showed on their emotional response and the fact that many spent considerable time testing the model. This was exactly how we intended it to be used; no rules/manual, just exploration. The employees at Rockheim were also positive in their feedback, and asked us to exhibit the model for a weekend. During this exhibition, we also received much positive response from the outside visitors. As for the external sensor, we didn’t catch who it was… So we don’t know.     ...
