# Cloth modeling

Cloth modeling – Wikipedia, the free encyclopedia.

Or – do a search for cloth physics.

This is very similar to the spider on a web project idea.

# Pulse Oximeters – Maxim

# Model a non-linear pendulum that has magnets.

Check the video below. It is a simple pendulum, but reacts to magnets near the base. A non-linear problem to be modeled with RK – but not too difficult. http://en.wikipedia.org/wiki/Force_between_magnets#Magnetic_dipole-dipole_interaction

# Implement an adjustable step-size RK algorithm for animations

The animation system at http://lpsa.swarthmore.edu/Animations/ uses a fixed step size animation. Alter the code to use a variable step size.

# Use an animation system (see below) to develop animations for homework problems.

Use the animation system (http://lpsa.swarthmore.edu/Animations/) developed by a student a few years ago to develop animations for some of the homework problems.

# Use simulink and MATLAB together to simulate a system (and animate it).

Use simulink and MATLAB together to simulate a system (and animate it). You could also do it all in MATLAB. The coupled pendulum system comes to mind.

# Simulate this non-linear system with spinning magnets.

Simulate the system shown using Runge-Kutta (it is nonlinear, but not too complex). http://en.wikipedia.org/wiki/Force_between_magnets#Magnetic_dipole-dipole_interaction

# Explore Z-Transforms

Z-Transforms are related to the Laplace Transform, but are used for discrete time systems (i.e., when a computer is used to sample a signal). This would be more research then physical.

# Javascript tool for demonstrating some principal from class.

Develop an interactive JavaScript tool for demonstrating some principal from class. … pole locations and step response? pole locations and Bode Plot? animating the Runge-Kutta process?

# Javascript tool for visualizing convolutions

Use JavaScript to develop a tool for visualizing convolutions. Something like “The Joy of Convolution” from Johns Hopkins, or the MATLAB tool ConvolveGUI that I demoed in class.

# Control Servo Motors with an audio signal.

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:.

# The Pi Machine – NYTimes.com – Calculate pi

Use this method to make an animation (web-based?) that calculate pi. The Pi Machine – NYTimes.com.

# Use Audio Analyzer to Demonstrate Convolution

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.

# Use a 3D printer to make circuit boards

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

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

# Add code to Fourier Series Lab so Function Generator makes Sawtooth and Triangle wave

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 shaker table + building for E12 lab

Build a shaker table with sinusoidal input that shakes model building that is instrumented with accelerometers.

# DSP Codecs Use Beamforming to Optimize Voice Signals

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.

Explore Fourier Transform and Filtering in 2 dimensions (i.e., images).

# The hot rod.

Put a heater on one end of a metal rod, and measure, predict and model the temperature along the length of the rod.

# Compartmental modeling (physiological systems)

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.

Analyze and simulate the double pendulum without the small angle approximation. Include an animation.

# Build an analog computer.

Build an electronic analog computer (a circuit analog to Simulink) using integrators and summers….

# Try to model the friction of the double pendulum experiment.

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).

# Develop a thermal model for a hot box.

Put a heater in a box and try modeling the temperature in the box over time.

# Develop a system to measure hand position and develop a model.

Build a small dial with a pointer and measure the transfer function of your hand as you try to follow a moving target.

# Model a spider on a spider’s web.

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.

# Explore the audio impulse response of various areas around campus.

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.

# Explore a triple pendulum system

We have a triple pendulum system – explore the modes of oscillation of this sixth order system, experimentally and in simulation.
