If you have an idea for a senior project and are in search of an advisor, please contact me if you think our areas of interest might overlap. Check out some GUIDELINES for senior projects and thesis projects. Drop by my office (20-304) or send an e-mail to dbraun@calpoly.edu.
  • Sustainability
    Use your senior project to enable future generations to meet their needs. Perhaps you see an opportunity on campus. Off campus opportunities abound, too.
    Three ongoing sustainability projects on-campus require contributions from senior projects:

    • Energy Harvesting from Exercise Machines (EHFEM) pronounced "FM"
      Prior teams have modified an exercise bike, rowing machine, and elliptical trainer to produce DC & AC power as a standalone system. Teams are currently working on systems to deliver generated power back to the grid.
      EE Senior Project Student(s) Needed Design a Buck-Boost DC-DC Converter using the LT3791 controller. (2013-2014)
      EE Senior Project Student(s) Needed Design an improved input protection system for DC-DC Converters. (2013-2014)
      EE Senior Project Student(s) Needed Design a custom transformer for an Active Clamp Forward DC-DC Converter. (Continues 2013-2014)
      EE Senior Project or EE Masters Student(s) Needed
      • Design DC-DC Converter control systems for input impedance matching. (Continues 2013-2014)
      • Design DC-DC Converter control systems for PV Inverter MPPT Algorithms. (Continues 2013-2014)
        • Perturb and Observe – Moves V based on dP/dV.
        • Incremental Conductance – Moves V to seek dI/dV = – I/V, when dP/dV=0.
      EE Senior Project Student(s) Needed to deliver generated power more effectively from the exercise machine to the grid. (Continues 2013-2014)
      EE Senior Project Student(s) Needed to design DC-DC converters to improve power delivery from the exercise machine to a battery or the grid. (Continues 2013-2014)
      CPE Senior Project Student(s) Needed for the display system to deliver power generation data to Rec Center athletes and the web. (Continues 2013-2014)
      EE & CPE Senior Project Student(s) Needed to improve performance on one of the above projects or find and modify another exercise machine to generate power. (Ongoing)
      EE Masters Student(s) Needed
      for DC-DC converter and inverter design. (Ongoing)
      EE Senior Project or EE Masters Student(s) Needed to perform the multi-machine design and install in the renovated Rec Cen. (Ongoing)
      SUPPORT: This project gratefully acknowledges equipment donations from Concept2 Inc., Advantage Fitness Products, and Enphase Energy.

    • Efficient Deployment of Advanced Public Transportation Systems (EDAPTS)
      Jeff Gerfen's research project developed the Smart Transit System for San Luis Obispo, most visible until Summer 2009 as bus signs predicting bus arrival times based on radioed GPS data. Prior projects redesigned sign systems. We now post bus position and arrival predictions online. See the first prototype, developed by Jeff Tikkanen at http://decade.eel.calpoly.edu/EDAPTS/. The current verstion, developed by Aaron Berk and John O'Conner, reflects 2010 route and schedule updates.
      1. CPE Senior Project Student(s) Needed to improve the bus arrival predictions.
      2. EE or CPE Senior Project Student(s) Needed to interface the MySQL database with the new GPS system and radios.

    • 2700K White Light LED Luminaire Development
      Energy efficiency needs and global warming concerns have driven incandescent lighting from its primary position. Similarly, fluorescent lighting will give way to LED lighting. White LEDs are now available with warm light, color temperatures such at 2700K, which people tend to enjoy more than harsher 5600K lighting.

    If you're interested in solar energy, consider an comparison of inorganic and organic photovoltaic systems from manufacturing to economic and thermodynamic payback.

  • MoHAT Tool Improvement
    1. Use LTSpice to illustrate Transistor and Diode Modes of Operation on the Circuit Schematic. CPE or EE Senior Project Student(s) Needed
    2. Automate LTSpice simulation results measurement and schematic generation. CPE or EE Senior Project Student(s) Needed

  • Electronics Lab Improvement
  • Do you see room for improvement in the core Electronics Labs? Here are opportunities for you to use your senior project to do something about it:
    1. The EE 346, EE 347, and EE 348 electronics labs need a new prototyping environment to handle SOIC footprint parts and other surface mount parts. EE Senior Project Student(s) Needed
    2. If you would like to learn about GPIB data acquisition and LABVIEW programming, consider a project involving electronics instrumentation.

  • Polymer Electronics Lab Projects
  • I am quite interested in solid-state electronics in general and polymer electronics in particular. These areas include solid-state devices such as light-emitting diodes [LEDs], lasers, photodetectors, solar cells, and field-effect transistors [FETs]. Other interests arise from electronics used to drive displays, low power electronics, and VLSI. Device fabrication and characterization overlap with practical issues in the areas of laboratory automation, vacuum systems, and inert atmosphere processing. Specific projects appear below.
    -- Device characterization projects focus on electronics, but they can also reach into the realms of software and other disciplines.
    -- For a research oriented project, you could make polymer LEDs or solar cells and improve their efficiency.
    -- If you like Chemistry, you could make new molecules and polymers for polymer LEDs.
    -- Improving the lab entails a variety of EE, CPE, ME, MATE, Chemistry and/or Physics activities.
    -- Added Fall 2008: Develop packaging schemes to allow using the polymer LEDs outside of the glove boxes.
  • Interactive Animations of Solid-State Electronics
    Web-based interactive animations can bring to life the operation and circuit applications of diodes and transistors. Some examples have been published on the web. See for example the links on Courses. This project requires an imaginative approach to web page design.
