Welcome to the Log!

This week we established our schematic of visual-beats and has worked on the proposal. Instead of simply generating frequencies from speaker/amplifier, we decide to connect a xylophone to the Arduino board. So that we can see different patterns generated from different xylophone musics. We talked with our TA, Will about the theoretical feasibility and other potential improvements.

We are in the process of completing multiple sketches and finalizing our plan before purchasing items. We are working on laying out a detailed process of the piezo signal transmission from GarageBand to the Amplifier and the figuring out the computation of the Kirchoff-Love Plate theory into 3-D Models. We might be choosing to use a smaller speaker, but need to do more research in order to understand the level of sound we will be working with. We have considered using surface transducers/oscillator motors, but since we would rather have an output that plays music, we chose to stick with an optimal speaker. Understanding the audio engineering to how speakers work is a must before we begin building anything.

We spent this week "coming down to Earth" with our ideas and decided to let go of the xylophone as our project is already dense without it. Instead of using a speaker and having to hassle with connecting its coil to the plate, we found an object called the Exciter which is an electromagnetic coil used to impact sound on plates. This caused our prototype model to be rearranged with new materials as well, which you can view from our wiki page.

Our plan with the Arduino is to connect a DAC to the Arduino board so the digital signal would be converted to analog signal. Then we "amplify" the signal by connecting an amp to the DAC.
