Projected Baseline and Reach Goals

So far we have our motor software working, and we're very close to completing a single tone-wheel rig.

The picture above is a photo of our motor mount.

Here is a photo of our tone wheel constructed from a steel band saw-blade wrapped around a laser-cut disk.

For our motor driving software, we made the decision to move the speed actuation component to an mbed to be able to free up more power on the PSoC board for signal processing.

In the next few days, we will construct the magnetic pickup fixture, and write the audio signal processing software for the PSoC. For our Baseline goal, we plan to have the single tone wheel apparatus up and running. The tone wheel will be producing one constant analog audio signal that will be digitally pitch shifted by the PSoC to support a range of notes. For our Reach goal, we would like to implement MIDI interfacing to support a MIDI keyboard for user input. Also, we would like to produce more analog signals for better audio quality by either adding on more tone wheels of different sizes or writing code to change motor speed as the user presses different notes.
