    Midterm Journal Entry 2: pulse sensor Runner’s band 

    The look at feel for my project is practical and simple. I want to embed the pulse sensor and an array of lights and possibly a speaker into a cotton wrist band. The lights that are aligned linearly with in the band will gradually light up appropriately as the users heart rate increase or decreases. The battery will also be embedded with an pocket that can be easily accessed when changing it. I also would like to add a light sensor as an on and off/reset switch.

    -What surprised you?-

    The wiring is fairly simple so I quickly wired up one LED at the start and attempted to slip my newly purchased arduino NANO into my wristband. The pins on the NANO make it extremely difficult to cleanly place inside the band and also make it uncomfortable to wear. Also, the led itself is rather large.

    So I have decided to use a lily pad and possibly some smaller flatter LEDs if I can find them. I think I’ll also steal a small speaker from a pair of headphones.

    I hope to have a usable and integrated prototype by Monday.

    Any suggestion from any of you would be awesome.

    TSG phase 2 

    I have cleaned up my code and redesigned the pcb to a smaller more compact circuit. Tomorrow Joel Murphy will walk me through the pcb etching machine to print the board out. I am very happy about how it turned out. You can see an image here: 


    I have picked out the new fabric:


    In order to finish Theater Safety Glasses 2 I will attend Rhino workshop on Saturday to print the part that encases the battery circuit and servos, and assemble the pieces tighter. Creating a circuit for it has been spending and I hope that creating a 3d file will be as rewarding and useful.

    Amira and Ramiro’s Midterm Journal 2 Entry 

    pictures above in order: 1. physical prototype 2. Code( next phase ) 3. Cards ( look and feel )to indicate patterns players should attempt to mimic using their BMP


    In 4-8 sentences, Describe what how you will work on your prototypes between now in next class.  What is left to do?  What surprised you?

    Between now and next class Ramiro and I will

    1.) Implement and refine final physical protoype. —We will make 2 controllers so that there is the option to play against another person as well as yourself.

    2.) Transfer our paper version patterns to actual cardstock — we will make a complete deck of patterns for our players to compete.

    3.) Refine our code

    Our materials to house our final version/hardware has been ordered and we await its arrival. We will be using a wooden casing to house our Arduino because of the look and feel it provides.( Also our metal version is conductive and interferes with the hardware.

    Norman Diaz’s Midterm Journal Entry 2 (Ambient Lamp) 

    As a reminder my project will be an ambient lamp, lighted up by an RGB LED and controlled by the pulse sensor.

    For the look and feel prototype I’ve been working on the design of the lamp. I was inspired by the arteries of the heart and came up with and abstract shape that represents them.
    After having a final design of my lamp, I started the 3d modeling which will help me have some renders to represent how my design would look in my next prototype and then be 3d printed.

    For my Implementation prototype, I decided to use only one RGB LED to change the colors of the lamp, and currently working on it.

    Robot prototype 

    I finally received my Speakjet from Sparkfun so I spent some time carefully soldering that together so I can get my bot speaking. Not as simple as I had hoped. I’m still building and testing the components to make sure they will all fit and work inside the robot. I prototyped a few different sets of eyes based on the input of my classmates. One option is to mount the LEDs externally in plastic caps and another is to enclose the LEDs in little fabric “dumplings” to stitch inside the head. Both options create a different effect so I’ll keep testing. Ultimately, I think I’ll commit to mounting the LED heart inside the robot – it gives off a nice glow behind the printed black fabric. The pulse sensor is still giving me a little trouble so I need to work on the mounting situation in the robot arm. After that… code, code, code…and more code.

      Mike, if you are getting to much light “bleeding” from the eyes you can: 1) put a higher resistor on the LED so it’s more dim OR 2) make the dumpling smaller or 3) explore a way to stop light bleeding from the edges like a different dumpling material….?

        Thanks Yury. Hope you are feeling better. After testing about 15 different eye configurations, I finally committed to using the clear caps on the outside with a higher transistor rating to dim the LEDs a bit. Using the LED dumplings inside the head produced a cool effect but after some user testing people preffered the look of the externally mounted eyes. I’m now trying to make a similar decision about internally or externally mounting the heart LEDs. I’ll bring my prototypes to class on Monday.
