Use the ideas in this post to control servo’s with audio signals from a cell-phone or other audio source. TRS Drawbot – Make: | Make:.
Use this method to make an animation (web-based?) that calculate pi. The Pi Machine – NYTimes.com.
It would be very nice to have a MATLAB gui that makes the audio analyzer output a series of impulses to a circuit and then have software that would add up the delayed and shifted impulse responses to create the output due to an arbitrary input. This is ambitious, but if you want a very software (MATLAB) intensive project – this might be it.
Materials for 3D Electronics Printing — Voxel8: 3D Electronics Printing. This is an ambitious project – you may want to consider this for two students unless you have some experience building your own 3-D printer.
Recreating the THX Deep Note – Earslap. Read this blog post on how to create the THX Deep Note (the sound at the beginning of movies using THX). It involves some signal processing – see if you can do it in MATLAB. Here is professor Zucker’s implementation in shadertoy https://www.shadertoy.com/view
Right now, the signal generator is only configured to create sine waves and square waves. Code could be added to the U8903a GUI to enable the generation of triangle and Sawtooth waves.
Build a shaker table with sinusoidal input that shakes model building that is instrumented with accelerometers.
Design you own beam-forming microphone array, or come up with a novel application for this integrated one. DSP Codecs Use Beamforming to Optimize Voice Signals | Embedded content from Electronic Design.
Explore Fourier Transform and Filtering in 2 dimensions (i.e., images).
Put a heater on one end of a metal rod, and measure, predict and model the temperature along the length of the rod.
Read up on compartmental modeling and model some physiological system (e.g., glucose metabolism…)
Analyze and simulate the double pendulum without the small angle approximation. Include an animation.
Build an electronic analog computer (a circuit analog to Simulink) using integrators and summers….
Try to model the friction of the double pendulum experiment. The friction is closer to kinetic than viscous, so you’ll need a non-linear model (either your R-K, or simulink). This has some interesting aspects to it (as friction often does).
Put a heater in a box and try modeling the temperature in the box over time.
Build a small dial with a pointer and measure the transfer function of your hand as you try to follow a moving target.
Try to predict the deformation of a spider’s web with a spider sitting on it – you could model the web as springs and dashpots.
Record the audio impulse response (pop a balloon) and record the audio impulse response of various locations around campus. Play various sounds through the impulse response and explore the results.
We have a triple pendulum system – explore the modes of oscillation of this sixth order system, experimentally and in simulation.
Get data from double pendulum using a vision capture system.
Explore filter types (Butterworth, Chebyshev) – try them out on the EMG data from lab – see if you can get the same results as the BioRadio software (you can also play with the filters from within their data collection software)
Redo the double pendulum experiment with better and newer hardware.
- Use an air track to get oscillating masses instead of pendulum (or some kind of “air” bearing) (to reduce friction).
- Measure position/velocity wirelessly (so no friction), or with a permanently mounted webcam with image processing software.
- Put everything together in a robust and easy-to-use package.
This project combines, mechanical, electrical (maybe) and computer work.

Taiyo Yuden Lithium Ion Capacitors: An Effective EDLC Replace
The pdf http://www.marvell.com/led-lighting/assets/Marvell_88EM8189_IC-01_product_brief.pdf describes a chip that can be used for low power wireless control, and can be powered directly from 120V line voltage. Build a small wireless device (motor control, light dimmer….) Note: this uses zigbee so you’d need to work on both ends of the network.
Use the MSP430 and the E15 I/O board to make a thermometer (using MSP430 internal temperature sensor) and/or thermostat (using potentiometer for “set” temperature).
