proposal
We are proposing to build an electronic system that behaves just like a grand piano without there being any physical object to receive key presses. We are planning to build the entire piano with 88 keys with sustain and touch pedals to authentically reflect the characteristics of a grand piano.

[Idea Post: https://courses.engr.illinois.edu/ece445/pace/view-topic.asp?id=25719]

To isolate the location and motion characteristics of a key press we plan to use multiple camera modules facing the player’s fingers which would be equipped with reflective material at the fingertips and accelerometers attached to each finger to provide information about the touch force. The input from each of the camera modules would be processed in real time using an FPGA and relayed to an audio synthesizer that would play the note on a speaker with the appropriate note and amplitude. We are planning to build the audio synthesizer to control aspects of the produced sound but only when we are done implementing the controller module.

We believe this would be a challenging project for senior design due to the complexities involved in processing and isolating each of the user’s finger locations in three dimensions in real-time and incorporating readings from the wireless accelerometers and sustain pedals. We have not encountered a virtual piano implementation similar to ours that uses camera sensors and accelerometers to isolate the user’s hand movements.

Pocket Pedal - A Bluetooth Controlled Effects Box

Featured Project

Our idea is to make an inexpensive alternative to traditional pedal powered guitar effects boxes. Essentially, we hope to implement a single aftermarket effects box that can be remote controlled via a mobile app. This low-power, Bluetooth connected application can control the box to change effects on the go. The hardware within the effects box will be able to alter the guitar's signals to create different sounds like echoing, looping, and distortion effects (and possibly more). These effects will be implemented using analog circuits that we will design and construct to be controlled by an app on your phone.

This project eliminates the expensive buy-in for a guitarist hoping to sound like any number of famous musicians with multiple effects pedals. On top of this, it also aims to get rid of the clutter that comes with the numerous pedals and boxes connected to an amplifier. Many pedals today don't even have a visual interface to select effects through some sort of menu. The app will also provide a much more handy and portable visual representation of the possible effects all from the phone in your pocket!
