Magic Mirror Infrared detector

Building robotics and electronic installations with IR sensors can be a hassle when detecting objects. At the moment I am working with several Sharp IR sensor that I suspect interfere with each other, picking up each others bounce light. I saw this need neat little IR detection card that displays your IR light so you know exactly where your IR sensor bounce back on objects.

Investigating these cards further I found out you can use a digital camera to catch the light. The human eye can’t see the IR light but the digital camera can! Just turn on your digital camera and view your sensor through the camera.

Using my iPhone camera I could clearly see where my Sharp GP2D12 reflected back the IR light and I could adjust the IR sensor face the object more accurately.

In the Javascript function FB.ensureInit you can then put in your API calls and generate your HTML from that. Below is an example of showing selected information from a user’s profile.

<script type="text/javascript">
var widget_div = document.getElementById("profile_pics");
FB.ensureInit(function () {
FB.Facebook.get_sessionState().waitUntilReady(function() {

  var session = FB.Facebook.apiClient.get_session();

  FB.Facebook.apiClient.users_getInfo([session.uid], ["about_me","books","interests","movies","music",
"religion","tv","quotes","education_history","political","sex","meeting_for"],

function(result) {
  var markup = "";
  for(var o in result[0]) {
  markup += "<br>" + o + " : " + result[0][o];
}
widget_div.innerHTML = markup;
FB.XFBML.Host.parseDomElement(widget_div);
});
});
});
</script>
