Story

We believe that if we are not making someone elses life better then we are wasting our time. We chose the athletes and we wanted to help them to perform better and avoid injuries during the training. Simultaniously we came across a Google's ATAP project called Jaquard which gave us the confidence and motivated to build somthing to the athletes and make their life better. This led to the SFAC to happen.

We want to make it a product at the end but we still have a long way to reach there. We made it as a goal of the year 2016 and started off on 13th January 2016 with all the Hardware and Design. People didn't believe in us and we kept it going. We made a deal with 2 of our friends saying. "If the project works then we take in the share else every thing is on us." It built a preasure in a good way. We learnd to program everything by ourselves and with the help of the internet ofcourcse. We made research to find a spot on the athletes body which has not much motion to disrupt the hardware. We found the upper back is the right spot to place the hardware and tested it with different shapes using foam. We chose foam just because it was left abandoned in our College in the Lab's Store room. We thought it would protect the hardware from sweat but later decided to choose regsine (false leather) to protect the hardware from sweat.

We made our first program work in eary March and by the end of that month we stitched the hardware and started testing and optimising the sensors with athletes in stadium.

We wanted to make sure that the SFAC doesnt disturb the athlete's performance. We built a shell to protect the hardware and 3D printed it from 3ding.

We have been asked so many questions in various expo like.

Can you reduce the size?

How different is it from the smartbands?

Why did you choose this hardware(UDOO)?

Can you increase the battery performance?

These were the common questions and here are our answers to them.

Can you reduce the size?

Yes, we can reduce the size even more if we want to make it commercial product.

How different is it from the smartbands?

Smartbands can track very less when it comes to sports like it can sense weather you are sitting or standing but SFAC does it even more it knows your body posture while performing.

Why did you choose this hardware (UDOO)?

We realized it is the only board that in a size of a creditcard with power of somany other boards combined together. In many ways it is the best thing happend to us.

Can you increase the battery performance?

Yes, we can make it but we need to use paper Li-ion which is best for this application. We can make use of the extra space in the shell and utilize it with battery.

We are now in the phase of building a grid to bring interactivity to the T-shirt. We will be coming our with that result maybe by few weeks.
