Arduino Miniconf

  • <1> High Altitude Arduino: Horus by Joel Stanley and Mark Jessop
    • 很好玩的一個專案,用 Arduino 做高空氣球的資料量測。展示影片很好玩,把企鵝玩偶跟著高空氣球丟到接近外太空~
    • http://projecthorus.org/
  • <2> Shield Design: Do It Right! - by Jonathan Oxer
  • <3> Network of Things - Andy Gelme
  • <4> Arduino in Security - by Philip J Lindsay
    • http://www.sparkfun.com
    • 既然 Arduino 會連在網路上,也一樣需要資訊安全的保護。
    • New Arduino UNO 加入 Real USB 而不是軟體模擬,多了一塊 WiFi 的板子(WiFly Shield)、GPS Shield、MicroSD Shield
    • WiFly wrapper library
    • https://github.com/sparkfun/WiFly-Shield
    • 把所有新軟體加一加,變成 Open Layers 函式庫,可以用 Arduino 結合 Open Street Map 提供定位服務
    • Make Something! Document it too!
  • <5> Greenhouse Control Using Arduino by Bdale Garbee
  • <6> Building Smart Outlets Using Arduino by Jazz Yao-Tsung Wang
  • <7> No REST For The Arduino - by Aneesha Bakharia
  • <8> Lunar Numbat Board Design by Luke Weston
