    Lie Detector 

    Lie Detector v 1.0

    For our pulse sensor assignment, I wanted to do something with the data that revealed something a bit more personal about the person. For the Lie Detector, I went for an old carnival type of look. If the user’s pulse jumps above 75 BPM, the LOL shield displays the word “lie.” If the BPM stays normal, then a happy face is displayed.

    Lie Detector v 2.0

    I definitely wasn’t happy with the construction of the original prototype, so I attempted to make a more finished enclosure for this version. I decided to make a retro look and feel for the device. The actual enclosure is a wooden box. I decided to lose the LOL shield and use simpler, more universal feedback to let the user know whether or not a lie was being told. I drilled holes through the front for LEDs and capped it with red and green plastic tops. I also added a velcro strap to the actual pulse sensor, which dramatically increased the reliability of getting accurate pulse readings.

    Lie Detector Final

    What was lacking from the second prototype was there was no indication that the lie detector was working. I added in some LEDs on top to convey that part of the experience. To finish the look, I laser cut the words “lie detector” and hot glued them to the front. The user first straps themselves into the device by velcro-ing the pulse sensor to their index finger. They are asked a question, and after answering, the black button is pushed to begin BPM analysis. The LEDs on top blink to show that it is calculating, and then the result is displayed by either lighting up the red or green light.

    While initially made for fun with friends, it could also be used in other practical situations as seen below.

    Harry Potter “Pumpkin” v 2.0 

    For one of my final projects in this class, I decided to improve upon my Harry Potter pumpkin enclosure made for Halloween.

    To recap, the Harry Potter pumpkin interacts with you based on proximity. From far away, he is sad and sits quietly with red eyes. As you move closer, he becomes curious– his eyes change to green and the tip of his wand lights up. If you are really close to him, his eyes change to blue and he hums the Harry Potter theme song.

    In order to make this more of a finished piece, I obtained a new enclosure. The head is a plastic container. I drilled holes in the sides to accomodate for the mini speaker wiring, and to expose the photocell at the top. I used  chopstick for the wand and covered it with black felt. Hook up wire runs from the inside of the head to power the light.

    Parts Used

    RGB LEDs
    White LED
    Mini photocell
    Mini speakers

    Robot Love Story Iteration 2 

    For my short film Robot Love Story I created a black viewing box with a fabric curtain, reminiscent of the old timey movie viewing boxes. The button is in the back and initializes the movie. Putting your face close to the box creates a nice viewing experience for the film and also makes the led’s easy to see. The code is the same as iteration 1.
