Dragonfruit

Dragonfruit is currently the bleeding edge weatherbox design that is meant to table problems with the cranberry design. Cranberry addressed major issues with Apple but more or less fell short on design quality.

Fall 2015

  • Research and design a new board
  • Get a working prototype by the end of November
    • Accurate readings from each of the sensors
    • Low power consumption
    • Communication between module and server

Spring 2016

  • Produce a working prototype

Programming Instructions

  1. Use the Arduino IDE to program the device using the AVRISP MkII Programmer.
  2. Use an ISP connector to attach the programmer to the DragonFruit board.
  3. Connections: MISO (1), VCC(2), SCK(3), MOSI(4), RESET(5), and GND(6).
  4. Make sure that you have the right board selected: Arduino Uno w/ Atmega328.

Note: Board must be powered using an external voltage source (e.g. battery or generator).
