===== Status =====
  * we have a few [[wp>Wii_Remote]]s ([[user:ruza]], [[user:pasky]])
  * wire up some IR leds
  * port C#/DirectX code to something Linux friendly (e.g. C++/OpenGL) ([[user:pasky]])
  * enjoy!


===== Whiteboard =====

=== Status ===

<note>We have wiimote instantly powered, using Vishay TSAL6400 LEDs and gtkwhiteboard works fine</note>

  * [DONE] wiimote, [[user:ruza]] 
  * [DONE] tripod, [[user:ruza]] (optional)
  * [DONE] some type of mount (optional)
  * [DONE] 3V transformer ([[user:sargon]] helped)
  * [TO INVESTIGATE] software 
    * [[http://packages.ubuntu.com/search?keywords=gtkwhiteboard&searchon=names&suite=all&section=all|gtkwhiteboard]] works well 
    * http://sourceforge.net/projects/wiiwhiteboard/ (Linux)
    * http://johnnylee.net/projects/wii/ (non-Linux)
  * [DONE] infra LEDs, [[user:ruza]]
    * [[http://www.dealextreme.com/p/dx-12-led-ir-infrared-flashlight-silver-3-aaa-2047|IR 12LED flashlight]] but only when light is emited directly against WiiMote. IR light is also not visible when is more than ~3.5-4m distance (teoretical limit is 5m).
    *  Vishay TSAL6400 LEDs are the best for use with WiiMote according to few reliable internet sources and out tests.

=== Hardware ===

  * best [[http://www.wiimoteproject.com/ir-pens/electronics-101-sharing-my-mistakes!-***-updated-***/|InfraRed LEDs]] for use with WiiMote according to internet forums
  * 
IR pen with Vishnay LEDs emits so much IR light, we had to use Scotch tape to absorb light that is surplus

Wii is instantly powered by power  adapter

=== HowTo whiteboard ===

  * install lswm, gtkwhiteboard and wmgui ("apt-get lswm gtkwhiteboard wmgui" for Ubuntu 10.04 LTS)
  * turn your bluetooth on
  * be sure you have the same screen resolution on both, primary (LCD) and secondary (projector) screen. You will have probably problems calibrate gtkwhiteboard properly otherwise.
  * run lswm, follow instructions (press 1+2 on wimote), wait for BD_ADDR (BlueTooth Device Address). probably not needed, but it verifies blutooth connection.
  * run gtkwhiteboard
    * make sure following switches are on
      * [x] Calibrate on start
      * [x] Save options on exit
    * press Start
    * follow instructions (you will define corners of visible space for wiimote by clicking them with IR pen)
    * move your mouse cursor on projected picture by moving and emiting infra light against projection screen from your IR Pen

===== Pulse oximetry =====

The Wii Vitality Sensor is a fingertip [[wp>http://en.wikipedia.org/wiki/Pulse_oximeter|pulse oximeter]] sensor that connects through the Wii Remote. It was not released till this time and probably wouldnt be released anyways or in a bad quality. [[http://en.wikipedia.org/wiki/Wii_Remote#Wii_Vitality_Sensor|Wii_Vitality_Sensor]]
