  33 &lt;p&gt;Drew Fustini also did a very nice &lt;a href=&quot;http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/06/01/boothstache-facial-hair-fun-with-beaglebone-black&quot;&gt;&quot;BoothStache&quot; using BeagleBone Black at DesignWest 2013&lt;/a&gt; and did a very nice write-up.&lt;a href=&quot;http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/06/01/boothstache-facial-hair-fun-with-beaglebone-black&quot;&gt;&lt;img src=&quot;http://www.element14.com/community/servlet/JiveServlet/downloadImage/38-11795-151764/450-337/20130506_144729.jpg&quot; /&gt;&lt;/a&gt;&lt;/p&gt;
  34 &lt;h2&gt;How to build one&lt;/h2&gt;
  35 &lt;p&gt;Follow the instructions on &lt;a href=&quot;https://docs.google.com/presentation/d/1rb1Rvw05c1sFOoZiJ8Re86VVsU_-I90Ac0il8ZbXWD0/edit?usp=sharing&quot;&gt;the Google Doc presentation&lt;/a&gt;:&lt;/p&gt;
  36 &lt;ul&gt;
  37 &lt;li&gt;Buy &lt;a href=&quot;http://beagleboard.org/buy&quot;&gt;BeagleBone&lt;/a&gt;.&lt;/li&gt;
  38 &lt;li&gt;Buy PS3 Eye.&lt;/li&gt;
  39 &lt;li&gt;&lt;a href=&quot;http://beagleboardtoys.com/wiki/index.php?title=BeagleBone_LCD3&quot;&gt;Buy BeagleBone LCD3 Cape&lt;/a&gt; or another power source.&lt;/li&gt;
  40 &lt;li&gt;&lt;a href=&quot;http://circuitco.com/support/index.php?title=BeagleBone_Battery&quot;&gt;Buy BeagleBone Battery Cape&lt;/a&gt;.&lt;/li&gt;
  41 &lt;li&gt;For tweeting, buy &lt;a href=&quot;http://www.iogear.com/product/GWU627/&quot;&gt;Iogear GWU627 Ethernet-to-WiFi adapter&lt;/a&gt; and tether it to WiFi. To overcome the limitations of the small screen, you should probably configure it separately to the WiFi and then connect it to your board.&lt;/li&gt;
  42 &lt;li&gt;Assemble it together into some kind of case.&lt;/li&gt;
  43 &lt;li&gt;You might want to &lt;a href=&quot;http://beagleboard.org/Getting+Started#update&quot;&gt;update BeagleBone to latest image&lt;/a&gt;.&lt;/li&gt;
  44 &lt;li&gt;Boot board and login to console, perhaps using &lt;a href=&quot;http://beagleboard.org/getting-started&quot;&gt;the built-in USB networking and Gate One&lt;/a&gt;.&lt;/li&gt;
  45 &lt;li&gt;Clone repository and build:
  46 &lt;pre&gt;
  47 root@beagleboard:~# git clone git://github.com/jadonk/stache
  48 root@beagleboard:~# cd stache
  49 root@beagleboard:~/stache# make &amp;&amp; make install
  50 &lt;/pre&gt;
  51 &lt;/li&gt;
  52 &lt;li&gt;Edit config.js to include your tweet message, location of your LED control files and API keys for your Twitter account. To acquire your keys:
  53 &lt;ul&gt;&lt;li&gt;Sign in at &lt;a href=&quot;https://dev.twitter.com/&quot;&gt;dev.twitter.com&lt;/a&gt;.&lt;/li&gt;
  54 &lt;li&gt;Create an application on the &lt;a href=&quot;https://dev.twitter.com/apps&quot;&gt;&quot;my applications&quot; page&lt;/a&gt;.&lt;/li&gt;
  55 &lt;li&gt;Set the access level to &quot;read and write&quot;.&lt;/li&gt;
  56 &lt;li&gt;Create your access token.&lt;/li&gt;
  57 &lt;/ul&gt;&lt;/li&gt;
  58 &lt;li&gt;Make sure the date/time is set properly because Twitter requires it.&lt;/li&gt;
  59 &lt;li&gt;Double-click the BeagleStache icon to execute &apos;runstache&apos; and start the app running. Be patient and try not to start it up multiple times.&lt;/li&gt;
  60 &lt;/ul&gt;
  61 &lt;h3&gt;Alternatively building on BeagleBoard-xM, instead of BeagleBone&lt;/h3&gt;
  62 &lt;p&gt;I believe I used &lt;a href=&quot;http://angstrom.s3.amazonaws.com/demo/beagleboard/Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img.gz&quot;&gt;this SD card image&lt;/a&gt;.&lt;/p&gt;
