Design a wearable fitness monitor that measure pulse rate and oxygen saturation level of blood.
Design some kind of sensing network using the TI sensor tag – available in bluetooth and wifi.
I2S is a popular digital interface for audio, but is not supported on many microcontrollers. Design an interface from I2S to SPI (or I2C) that uses the smallest possible processor to do the work. Build a PCB/develop software….
See file here The file links to a paper entitled “Extracting the fingering and the plucking points on a guitar string from a recording”. Either explore the process (E12 project), or implement it (E71) in real time (E90)
Build a smoke detector that turns off when you say “I’m cooking”. Microprocessor/signal processing.
Develop a low power (battery driven) wireless device/sensor.
The Bluetooth Smart SensorTag is designed to shorten the design time for Bluetooth App development from months to hours by allowing App developers to write Apps that enable and use advanced sensors directly from a smartphone without any firmware or embedded software development.

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.
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.
Redo the double pendulum experiment with better and newer hardware.
This project combines, mechanical, electrical (maybe) and computer work.

Useful information on some E-ink type displays
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.
Designing a High-Efficiency Solar Power Battery Charger
Perhaps useful for E90, E72 or E15 project.

If you are interested in a wireless project consider using an “electric imp” as the hardware interface. http://electricimp.com/
Develop a display that can be controlled wirelessly (or wired) through an app or web interface.
Build a system that would allow for the creation of custom mosaics like the one shown below. The user would design mosaic and choose colors (based on available glazes). The individual tiles would then be formed (cut from a slab of wet clay?), dried, glazed and fired.
This project has an interesting mix of hardware and software and ceramics.
This seems like a useful design tool, but I’ve seen nothing like it.
Design and build a wireless timer for students giving talks. The student tlaking would have an LCD display that counts down the time left in the talk. A green LED could come on at some time as a warning, followed by a red one (and a buzzer?) closer to the end.
The person moderating the talk would have access to the timer through a web page.
The project is not incredibly difficult, but there is a wide variety of tasks (hardware/software/networks…) and the system must be robust and low power.
Build a shaker table (a building on a table that undergoes forced vibrations) for E12 labs that demonstrates modes of vibration. This is a nice project if you want a mix of electronics, hardware and software.
For control theory (or as E90) implement an active damping system for building.
Design and build an wing (or other structure) with integrated digital pressure sensors (perhaps with wifi or bluetooth) so that multiple pressure measurements can be taken with minimal (or no) physical connections to the data acquisition system.
A sample of a sensor (cheaper sensors are available) is at: SSCDANT030PG2A3 Honeywell Sensing and Control | 480-3338-ND | DigiKey.
