Connect the pi to a gyro ,and afoul motors for a quadrocopter



Posted by jasonzshi     Sep 7, 2013

I am thinking about attaching a gyroscope a, and four brushless motors to make a quadrocopter

I used a Raspberry Pi along with a PiRack, a Raspberry Pi camera module, a portion of a Pi Cobbler Kit, and a white LED to create a document camera for use in a high school classroom.  Document cameras typically cost hundreds of dollars.  Public school budgets are tight these days.  This RPi + PiRack + RPi camera module is an affordable solution that works with existing classroom technology (the projector that is already installed).  From the command line: sudo raspivid -t 0 -fps 20 -br 66 gives a nice image. At a height of around 13" above the document being examined, the document camera makes the writing on half of a letter-sized sheet of paper visible to all students in the classroom.  The older ceiling-mounted projector accepts composite video input.  This works fine.  Better viewing results could be obtained with a modern projector that had HDMI inputs.

Adding analog and digital interface card to Pi with remote control via Internet with Java or Bluetooth for local mobile access with same controls.
