Faking Magstripes, Embedded Database, Another Embedded Database, Multicamera Array

  1. magspoofa portable device that can spoof/emulate any magnetic stripe or credit card “wirelessly,” even on standard magstripe readers.
  2. LittleD — open source relational database for embedded devices and sensors nodes.
  3. iondb — open source key-value datastore for resource constrained systems.
  4. Stanford Multicamera Array — 128 cameras, reconfigurable. If the cameras are packed close together, then the system effectively functions as a single-center-of-projection synthetic camera, which we can configure to provide unprecedented performance along one or more imaging dimensions, such as resolution, signal-to-noise ratio, dynamic range, depth of field, frame rate, or spectral sensitivity. If the cameras are placed farther apart, then the system functions as a multiple-center-of-projection camera, and the data it captures is called a light field. Of particular interest to us are novel methods for estimating 3D scene geometry from the dense imagery captured by the array, and novel ways to construct multi-perspective panoramas from light fields, whether captured by this array or not. Finally, if the cameras are placed at an intermediate spacing, then the system functions as a single camera with a large synthetic aperture, which allows us to see through partially occluding environments like foliage or crowds.
