text: Falling In Love With My Sentilla Perk Kit
  I just received my Sentilla Perk (Pervasive Computing Kit) some hours ago (Picture 1). I want to thank Sentilla so much and, in special, Cheryl Hall, for being very attentive. If you don't know Sentilla yet, it wons the Duke Awards in Pervasive Solutions category this year at JavaOne!
  I have installed my kit on Windows Vista, it is described in the box that Windows XP is required. Anyway, it worked and it seems there is a beta version for Linux and Mac OS X too. The dev forum in the previous link needs registering, so be sure you create an user before.
  The basic steps to start are (from the instructions that came in the kit):
  -
  Sentilla Perk Kit is a CLDC-compliant Java ME-based platform (CLDC 1.1). Because talk is cheap, here it goes a very simple Hello World based on a code available on Mote Project. The snippet is very simple and blinks the red LED every one second. As you can see, there is no MIDP lifecycle and it defines its own libraries. The deploy on the motes are done very easy in the IDE using the gateway. The application running is in the Picture 1 as well.
  import com.sentilla.system.Leds;
  import com.sentilla.system.LedsDriver;
  public class MoteBlinkRed {
  public static void motemain() throws InterruptedException {
  Leds leds = LedsDriver.create();
  while (true) {
  leds.toggle(1);
  Thread.sleep(1000);
  }
  }
  }
  Get started too! Keep an eye here, my fun is guaranteed until the end of the year! :)
  Cheers,
  Bruno Ghisi

  by jpolastre - 2008-09-16 23:20Email me with the application you intend to create and you will get a free Perk kit.
  by brunogh - 2008-08-25 20:04Hello hlavalle, that is very weird, because I have heard about some brazilian people that got the project approved. Try to send an email to them. Thanks.
  by hlavalle - 2008-08-25 19:01Bruno, I went to look at the the Sun SPOT Open Grant Program you mentioned. But it is not for us, from Brazil, as it is not an eligible country.
  by pmac72 - 2008-08-20 15:56Right you are. I just had to fill in something in the MAC address field, there was no validation done on it.
  by brunogh - 2008-08-20 01:38Bruno--Thank you so much...CH
  by brunogh - 2008-08-19 18:29Thanks Jim! Probably will try something soon! :) Cheers!
  by jim_weaver - 2008-08-19 16:42Very cool, Bruno! So, are you going to write a cool JavaFX app for it? Thanks, Jim Weaver
  by brunogh - 2008-08-19 14:03erickson: Hello World is he idea to set up the whole environment and create something. Morse code will work, but I probably would take some time to understand it.
  by brunogh - 2008-08-19 13:58That is definitely a huge difference, forgot to mention. But, also, SPOTs accept proposals and gave kits for free:
  by erickson - 2008-08-19 13:49If it's "Hello, World!" shouldn't it actually say "HELLO WORLD" (in Morse code)? :) That would be cool.
  by tirulegui - 2008-08-19 13:29The main difference between Sentilla Perk Kit and Sun Spot is price. The Perk Kit is $199 while SunSpot is $750. During JavaOne, Janice Heiss wrote an article referencing the two ()
  by brunogh - 2008-08-19 09:26Hello dxxvi , maybe this interview with Sentilla CTO made at JavaOne () can help. They bring pervasive computing, but there are differences in both devices, like SPOTs are open source, uses IMP profile running on a Squawk () , etc. Both are amazing to create those fun stuff!
  by dxxvi - 2008-08-19 08:33What's the difference between this Sentilla and the Sun Spot Java Development Kit?
  by brunogh - 2008-08-19 05:55UPDATE: Sentilla is launching a developer portal:
