ROHR

ROHR (Reaching Our Heart Rate)

Shameya, Jackie, Simon


Problem

  • Athletes are not being able to fully track their progress in getting stronger than they already are. People may be overworking their hearts, and they won’t really know it nor know their BPM.
    A problem that we, Shameya, Simon, Jackie, are having is not being able to show the HR in a creative way and not being able to figuring out how to program things.

 Our Solution

  • Allowing athletes to know their HR, by the way our product will demonstrate it.

 Project Description

  • To make a shirt that can track your heart rate in a creative way. The shirt will be hooked up with a HRM, displaying your BPM by clicking a button. It will display your BPM with many LED lights that will flash accordingly  to your beat.

 Our First Prototype

Our Audiences/Clients
Our target audience are athletic people, both genders, any age.


 Key Design Questions

  • What does the Pulse Sensor measure?
  • What programing do we need for it to interact with touch screen?
  • What genders can use it?
  • How does it satisfy the one who will be using it?
  • How could we make our own heart rate monitor?
  • Who would benefit from it?
  • What program would we need to make it a touch screen?
  • What would we exactly need in order to do this?
  • How much would it all cost?
  • What Arduino would we have to use?
  • How could we make this wireless?

DAY 2: Imaging ROHR

Group members: Shameya, Jackie, Simon What is the problem that you are solving or what issues are you addressing? Athletes not being able to fully track their progress in getting stronger What will you build? heart beat monitor necklace and bracelet Who will use it? Athletes (runners, football players) How will it help? helps them track their heartbeats and push themseleves What are the 3 most important things tit will do? track your progress, tell you your heartbeat, alert you when you reach your goal What are its most important things it will do? pulse sensor, data feed, interactive screen What are the three technologies you imagine needing and how iwll you use each? scratch- create a broadcast modkit- program the sensor fab lab- making the products (fabrication)

 

Feedback Questions: 

What technologies would be used? Modkit, Fablab

What would convince someone to use your heart rate monitor over another which is currently in use today? Ours’ can be customized, it’s a different look.

Where would people use this device? Anywhere they go.

Is there a need for this particular device? Yes, some people that are interested in being healthy, people that works out, people that wants to know their heart rate can just use this device. Some people set goals for a specific heart rate they want to reach, also some people wants to make sure that they don’t go to high or too low, because that can be dangerous.

You were formerly thinking about having a target heart rate and having some kind of an alert when you reach your target heart rate. We are still able to do that, but we might not anymore.

You may want to talk to someone in the medical profession to get a little bit more information about these devices.

 

DAY 3: We figured out that bracelet idea might not be able to work out. So we decided to go with a T-Shirt, screen-print an image, (a design, (Tiger Face Logo) ) and sew on LED lights, have a patch cover the inside of the shirt. We want the lily pad sewn on the shirt. The patch will be velcro, we want a LCD display on the shirt, lily pad, and LED lights. Lily pad will be programed with the LED lights, if reaching a certain heart rate, this section of LED will light up. LCD display will show the heart rate, the pulse.

DAY 4: Project building day, we changed up the design and research. We attempted to try programing a prototype with an Arduino board, with a light sensor. Ed came by to see a progress on the prototypes and to learn more about the projects.

DAY 5: We researched what we kind of board would use, Lily Pad or Flora, and we decided to use the Flora. We also figured out about another sensor, a wireless sensor with bluetooth. We are using flat LED instead of regular LED lights. 

 DAY 6: We did more designing and decided to use the wireless sensor. We started to make a prototype with the Lily Pad, a screen-printed tiger, and LEDs, on a piece of felt. We got the tiger image online and used that for the prototype. 

 DAY 7: We are troubleshooting our project and making sure that our sewing isn’t the reason why or project isn’t working. We figured out that the pin we wired it to on the Lily Pad isn’t working. We also hope to finish our prototype today and try to program it to blink to imitate a heart beat. Lastly we will be looking at the feedback that we received from Becky Stern and making design decisions based on it. 

Project Building:

Today we continued our prototype that we started yesterday. For the troubleshooting. We figured out that the reason why the LED wasn’t exactly working was because it was hooked up to the wrong PIN, A3. So then we ended up hooking the LED to a different PIN, A2 and it started to work. Once we got it to start working, we hooked up more LEDs to it but on the tiger. We hooked up the LEDs one at a time. When we got all the LEDs on, we tested to see if all of them worked. At first it didn’t work, then we looked around at the circuit. We saw that we the wiring was touching one another so we trimmed it and fixed it up with electrical tape. Then it started to work. Once we got all the LEDs to work, we looked up the maximum heart rate for a 14 year old. After that, we did calculations for 70% use of the maximum heart rate. We then had to calculate the heart rate per second after we figured out the heart rate per minute. We successfully got the prototype to work and we imitated the average heart rate for a 14 year old, with the 70% use.

16 multipixels
where are we going to put battery pack and flora 
where are we actually going to put the multi pixels 
 
circuit and programing 
look at the circuit for the heart rate badge  
  • draw our circuit 
look at the programing 
-program line by line 
first figure out test script 
at the script to make it flash to a rate of a heartbeat 
 
test in modkit 
steal c code
c ++/wiring 
_______________________________________________

 

DAY 10: Today, we had to make a 1-1 scale drawing of our project. We researched how the to work with the multi-pixel because they were slightly more complicated than the other LEDs that we’ve worked with. 

DAY 11: Today we had to redo our 1-1 scale drawing, making it more neater and clearer. (For a better understanding of the Flora. http://learn.adafruit.com/getting-started-with-flora/overview)
We are also doing a more clearer copy of the circuitry of the tiger. 

Progress Since Last Update

The progress we’ve made on our project, since the last update, there were a lot of trail and errors. On our project we messed up on the circuitry a lot, we had to keep on redoing the sewing many times. Shameya, she soldered the bluetooth transmitter to the Flora. We tested the lights to make sure that our circuit would work, but then we later on realized that we needed to program the Flora in order for the RGB LEDs to light up. Shameya also done the programing. 

These three pictures shows the soldering that was done, connecting the Flora and the transmitter for the Polar T34(The wireless heart rate monitor). 

This photo shows the progress that has been made for the project. So far we got 10 out of 15 LEDs sown on and working. 

RESEARCH

  • heart rate monitors work the same for both men and women. It just all depends on the style, design, and what’s more comfortable for the one who is using it.
