  Romantic Lighting Sensor(Exercise 1) 

  “WIRELESS NETWORKING IS NOT NEARLY AS TRICKY AS NAVIGATING ROMANCE.”~Robert Faludi

  But here is what you can do:

  • Set up your COORDINATOR to API mode on X-CTU:

  

  
  

  • Note that after setting up your coordinator firmware to API mode on X-CTU, you can only configure your PAN ID(your chosen address),  ATDH(0013a200) and ATDL(the remainder of your routers address) on X-CTU as the following:

  

  • Then click Write button to save changes.
  • Set up your ROUTER on Coolterm:
    

  +++

  ATID (Same as Coordinator ATID)

  ATDH0013a200

  ATDL ( Remainder of Coordinator’s address)

  ATJV1 ( To ensure that router attempts to rejoin the coordinator on startup.)

  ATD02 ( To put pin “0” in analog mode.)

  ATIR64 [ To set up the sample rate to 10 times/second—1000ms/10=100ms=64(hex)]

  ATWR (To save the settings.)

  • Wiring ————ROUTER:

  

  • Wiring ————COORDINATOR:

   

  

  PITFALLS:

  Make sure your voltage regualtor is plugged in properly. If you have the LM1086CT the pin where etched circle is located would be GROUND, the middle one would be OUTPUT and the third one would be INPUT.

  Make sure your breakboard has the RIGHT pins connected to Arduino.

  When its all done, upload the first code that Kate posted.

  If everything is correctly hooked up you will observe this:

  Hostile Interaction Mediator & Doorbell 

  When thinking about ways of improving on the doorbell, it was hard to come up with ways in which it’s most basic purpose could be improved. But after living in apartments for a number of years, the most interesting part isn’t what happens when the doorbell rings, but rather what happens just after.

  Our front doors literally connect the interior to the exterior, but more than that, it is the one place where people tend to allow their private, inside selves to be on display to outsiders. When living near other people, it’s hard not to hear when Mr. Johnson has ordered Chinese food for the third time this week, or that Betty has very strong opinions about Jehovah’s Witnesses, or most painfully, when a couple two doors down is having a fight.

  So, in the spirit of highlighting this awkward exchange, Andy and I decided to make a doorbell that would allow two people having a fight to hash it out a bit without ever having to open the door. The device on the outside would have a standard doorbell, but also a variety of statements that would allow him/her to respond to any questions or statements by the the person on the inside.

  

  Initially we were going to give the user on the inside a keyboard to type specific questions to the person on the outside, but we were running into some serial issues and had to simplify our device to a more humorous and specific interaction. Even so, the person on the inside is in a more dominant position just by being inside already and controlling the door lock, get’s the chance to ask some pointed (albeit pre-chosen) questions of the guest.

  

  Also, the person on the inside has one extra button that the person outside does not: the FUCK YOU button. This fist-sized button will flash, in all capital letters, “Fuck You” over and over again and prevent the person on the outside from being able to send any messages back in. This implies that the conversation is over.

  The code for both of these actually sends the entire message over the XBee serial connection letter by letter. We built it this way since we were planning on sending typed messages). The code for each device is quite similar since this is a conversation and each is displaying to an LCD screen; the only difference is in the content of each message sent and that the device inside has a buzzer to indicate when somebody is at the door.

  Here is the arduino code for each:

  Internal/dominant

  External/abusee

  Salty Sandwich 

  Salty Sandwich is an old mate, whose lived in the refrigerator for too long. He’s become old and crappy, and doesn’t really want you to visit, however he does want you to return the items you take.  Upon entering the fridge users and greeted with a dissatisfactory hello, if there return is short, salty sandwich, is happy you are returning something, if it has been a long time, he does not want to see you.

   

  Below are some snapshots of process.

  Toy Fair 

  Overal quite an experience, crazy place and so much to see.

  Really loved the fish, I mean it was just amazing seeing how realistic it was in the air. Brilliant.

   

   

   

   

   

   

   

  

  Another great, which I’m sure drove Yury nuts was the AR drones, my inner child was all about these things and I could see myself with one of these. Great implementation of the camera and ipad/ipod/iphone. Really interesting.

   

   

   

   

   

  Finally i really loved this crazy kit from some random japanese company. It contains a hydro and solar cells, which you can use to power small dc motors. I would love some of these sets.

   

   

   

   

   

   

  There was lots of other really great stuff there, but most people wouldn’t let me take any photos. Oh well, still quite enjoyable.

  Love Coach 

  LoveCoach is a Relationship simulator targeted for young adults and above . It mimics the balance one must have when meeting somebody and after a relationship starts. “too much of something is never good”. It reacts to a light a sensor as light is is what nurtures the relationship, and reacts with sound and messages displayed on an LCD screen.

  

  

  A video and final photos will be posted soon…

  larry-in the closet… 

  

  

  

  This is Larry, he lives in the closet but he wants to “come out”. He has 8 different states of emotion which would be triggered if certain(14 !!) scenarios are active.

  Larry has dementia, his memory  resets it self every 12 hours.

  He cannot stand to be out for so long because he is socially awkward. The user has to give him a balanced attention to keep him content.

  If he doesn’t get enough attention he cuts his wrists and blames the user for it.

   (More ...)

  Toy fair 

  Even though they weren’t interactive the giant microbes were interesting to me because of my educational background. In the future I would like  to create electronically interactive biological forms.This was very inspirational to me.

  

  I liked geolovepalz, I think it was  smart in a was to engage kids in physical activities.

  

  I liked mugo because, it was simple and efficient, its a usb stick where u can store data and it also is a mp3 player. Its tiny and visually appealing.

  Toy Fair Impressions 

  Toy fair was amazing, I wish I could have spent all day there! It was so colorful and lively, I got lost among all those tiny plushy creatures.

  I have 3 top toys or maybe I can say categories:

  1. Laughing plush animals

  They are laughing and rolling over crazily when they see someone. They really cheer you up, you just wanna laugh with them.

  

  2. Owl Night lamp – Smart night lamps
  I saw 2 types of smart night lamps for children, which are designed to teach time through color output. Actually, I was so glad to see them because I had a project last semester with the same concept (even better – huh!). Anyway, I really like smart toys that have specific purposes.

  

  3. Science kits – Solar robots or toys that teaches science

  I am really interested in toys for educational purposes. These solar robot kind of toys are powered by wind or solar power and they are made of Lego. It has the power to teach physics to kids as well as mechanics, math even aesthetics.

  Magic Mirror 

  Magic Mirror can offer validation (if you need to feel good) or motivation (if you need your butt kicked). It can tell if you are close or far away and will offer comments accordingly. Also, it knows if the lights are on or off. If they are on and you are not nearby, it will alert you to turn the lights off! It uses a bitmap image based on the Magic Mirror from Disney’s Snow White, which was created on the PC using Adobe Illustrator and Bitmap Converter and then stored as an array of hex values which are converted using the ST765 LCD library.

    great concept. Great sound effects. If you 1)use a max of two words per screen & 2) make the text “face expressions” this project will transform.

    The text prompts would really be best as voice prompts. [In my view.] An iconic and graphic face with those cool sounds you have now, will make an R2D2 type experience. The user will be communicating with a mirror-bot, that has it’s quirky personality. At once and over time, the user learns to love and understand this cute little entity.

  Mirror buddy sits on the mirror in your bathroom and provides you with either motivation or appreciation depending on what you would like to hear. He detects how far you are away and make comments appropriately.

  Toy Fair 

  So I found the toy fair to be totally overwhelming. I might have been the cold… There were a lot of really creative ideas and a lot of things that were not so creative.

  Favorite things:

  AR-Drone

  “Swimming” fish balloons

  Science kit with fuel cell powered car

  Cigarette Box 

  The idea was to make a cigarette box for a person who wants to quit smoking. It contains the cigars in it so it detects each time you open the box to get a cigarette. Ideally, it would output how many times the box is opened, when it’s last opened (how many minutes passed since), a sad character if you open it too often, a happy character if you open it seldom. And it would play different sounds for different steps. One sound for 5th time, another more harsh one for 10th, harsher for 15 and a dying sound for 20.

  However, the code that I am using to output the the number of counter messes up all other sound codes. It happens so randomly that I couldn’t fix. Also, the smiley faces appear like blinking, I can’t clear the LCD screen after each shape because I need the counter and message to stay there.

  Now how it works: There’s a light sensor inside that detects if the box is opened or not. The LCD screen outputs the number of times the box is opened with a touchy message. It beeps each time you open the box, it beeps like an alert when you hit 5, 10, 15 times. There’s a smiley face in the beginning that welcomes, it turns into a sad face whenever you open the box and it turns into a laugh face when you do not open the box for a while. Right now, it’s 20 sec.

  

  Soldering the LCD and getting it work

  

  Outputting my own message on the screen

  

  Getting the message but not getting the graphic in the same screen

  

  Puff!!

  

  No! It’s not acceptable!

  

  Final look with flawed code

  

  At least I have the text and smiley in the same screen. Even if it’s ghost like sometimes.

  I was going to output a different message and sound each time the box is opened but couldn’t make it happen because the code that I’m using to output the integer into char is messing up the rest of my code 😦

  Here is the code.
