Overview• Quick review of previous talk

• What we’ve done since, including data

• What could be done to develop and

improve method

Limitations!• Piezo transducers are 3.7 cm in diameter…too big!

• Suspending guitar can be tricky…does not hang the

same way twice

• Time constraints

Page 12: Guitar Vibrations

Developments• Calibration of piezo transducers- correlating voltage

with space to develop plots w/ space dimensions as

z-axis

• Map out using more points with smaller transducers

• Understand better the DAQ graphs

• Laser Holography?
