Basics
We have a $500 Budget (funded!) to build an educational project to display and demo at the upcoming EDExpo (late February)
Plan
Build a portable, RaspberryPi based Lightboard for recording lessons/lectures/demos. A lightboard allows the instructor to write on a whiteboard in front of them while facing the camera. See: Northwestern Lightboard for examples
Status
The basic board is assembled and working.
The RaspberryPi and camera is set up to automatically boot into camera preview mode with the image flipped horizontally.
