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.

Smart Frisbee

Featured Project

The idea of this project would be to improve upon the 395 project ‘Smart Frisbee’ done by a group that included James Younce. The improvements would be to create a wristband with low power / short range RF capabilities that would be able to transmit a user ID to the frisbee, allowing the frisbee to know what player is holding it. Furthermore, the PCB from the 395 course would be used as a point of reference, but significantly redesigned in order to introduce the transceiver, a high accuracy GPS module, and any other parts that could be modified to decrease power consumption. The frisbee’s current sensors are a GPS module, and an MPU 6050, which houses an accelerometer and gyroscope.

The software of the system on the frisbee would be redesigned and optimized to record various statistics as well as improve gameplay tracking features for teams and individual players. These statistics could be player specific events such as the number of throws, number of catches, longest throw, fastest throw, most goals, etc.

The new hardware would improve the frisbee’s ability to properly moderate gameplay and improve “housekeeping”, such as ensuring that an interception by the other team in the end zone would not be counted as a score. Further improvements would be seen on the software side, as the frisbee in it’s current iteration will score as long as the frisbee was thrown over the endzone, and the only way to eliminate false goals is to press a button within a 10 second window after the goal.
