Projects:

  • PowerCube

    With the explosive boom in power demand, a huge strain has been put on the power generation infrastructure in the world. What the Cubic Inch Power Meter project attempts to provide is a simple, straightforward way for power consumers to be informed about the power use in their home or office. The hope is that an informed user will use this information to reduce their own power usage.

    The device fits into an unobtrusive cubic inch form factor and monitors power use in individual wall sockets. This information is fed into a central database where it is aggregated and displayed to the user over the Internet.

  • BlueLogic Logic Analyzer

    We are working on designing an ultra-low cost logic analyzer that operates over a Bluetooth link. Our design involves a Spartan FPGA and the Roving Networks RN-42.

    Challenges to this project involve a high sampling rate a low bandwidth Bluetooth link. Our low cost criterion restricts the use of extensive on board storage but our goal is 20MSamples/second and 256K samples recorded.

  • Environmental Sensing

    Working under Professor Robert Dick at the University of Michigan as well as engineers at the University of Colorado, Boulder, and abroad, I am helping to design and build a device for monitoring air quality.


Involvement:

  • Michigan Autonomous Aerial Vehicles. MAAV is a multi-diciplinary team of student engineers from EECS and Aerospace Engineering. Founded in 2009, we build autonomous quadrocoptors for the International Aerial Robotics Competition every summer.

    I am the team lead for the hardware subteam. We design and create printed circuit boards integrating stabilization and movement sensors with Gumstix and ARM microprocessors.

    View our promotional video for the 2012 IARC.

    MAAV won 1st place in the 2012 IARC! View/follow our progress at our competition blog.


Documents:

  • Resume
  • In order to save costs while producing high quality circuit boards, I have developed a technique for creating custom solder stencils using Cadsoft Eagle and AutoDesk AutoCAD. The technique uses a laser cutter. A pdf describing how to produce the necessairy files can be found here.

    A tutorial for using this file to actually cut the stencil can be found here.

  • In order to measure carbon footprint I am installing some circuitry in my car. The first stage of this is detailed here.
