			<content:encoded><![CDATA[<p>This FNR I added a speaker to BubbleBoy. I wanted to see how much better it would be to make a postulation as to how BubbleBoy is &#8220;feeling&#8221;, since it has &#8220;emotions&#8221;. Those words are used in quotes because they are represented in the code by single-layer perceptrons (without being trained), which really doesn&#8217;t do justice to the amount of processing needed to accomplish such tasks. This is just a trial to see if audible feedback will enhance the user&#8217;s experience of playing with BubbleBoy.</p>
<p>Here is a video of an explanation of what the user can see and hear:</p>
<p><iframe src="http://player.vimeo.com/video/18355778?portrait=0&amp;color=6cf000" width="400" height="225" frameborder="0"></iframe>
<p><a href="http://vimeo.com/18355778">BubbleBoy&#8217;s &#8220;Melodies&#8221;</a> from <a href="http://vimeo.com/robotgrrl">RobotGrrl</a> on <a href="http://vimeo.com">Vimeo</a>.</p>
<p>You can download the code here!</p>

<p>Oh, and I <a href="http://www.ustream.tv/recorded/11770780">streamed</a> while making this.</p>
<p>Soooo, I challenge all of you who are reading this to add a speaker/sound to one of your projects. It doesn&#8217;t have to be fancy! Leave a comment if you do accomplish this challenge, I would like to see it <img src='http://robotgrrl.com/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>For better or worse, I made a program for BubbleBoy that reacts to a light being turned on. </p>

<p>The program evaluates the light the same way MANOI&#8217;s hockey stick did. Once it goes over a particular threshold, it will begin to spin its hat and start saying &#8220;HELLO!HELLO!HELLO!&#8221;.</p>
<p><center><a href="http://www.flickr.com/photos/robotgrrl/3227892708/" title="BubbleBoy Lamp - FNR by RobotGrrl, on Flickr"><img src="http://farm4.static.flickr.com/3362/3227892708_d32a72880a.jpg" width="500" height="375" alt="BubbleBoy Lamp - FNR" /></a></center></p>
<p>At first, I wanted to make BB react to sound, so I dismantled a &#8220;haut-parleur&#8221; that I got a while ago, thinking that it was a piezo speaker. It&#8217;s actually not a piezo, because when I was looking at the analog readings on the Arduino, nothing happened if I fiddled with it. Weird!</p>

<p>When it says on the LCD that I&#8217;m at &#8220;cheel&#8221;, it is hardcoded in. I tried to use <a href="http://blog.tinyenormous.com/2008/12/02/arduino-based-rss-reader-with-lcd/comment-page-1/#comment-670">the script that downloads a feed</a>, but it doesn&#8217;t work for me, for some reason. I commented below that post with my setup and questions. =)</p>

<p>Aah I can&#8217;t wait until my Femsapien arrives from the EPFL! It is super boring without a humanoid to work on. <img src='http://robotgrrl.com/blog/wp-includes/images/smilies/icon_biggrin.gif' alt=':D' class='wp-smiley' /> </p>
<p>I&#8217;m not exactly sure what the moral of this FNR is supposed to be&#8230; annoy me and face &#8216;teh ultimate&#8217; BubbleBoy?! Hahahaha</p>
<p>I&#8217;ll add the video later in another post, Vimeo has a wait time of 130 minutes &#8211; and YouTube &#8230; well who knows about YouTube. o.O</p>
<p>I&#8217;m going to be working on an AI Library for Processing with a few people here at the COSI (hopefully). Expect many more posts about that! Woohuu! =)</p>
<p>That&#8217;s all for now. *turns lamp off*</p>
