I started to think more and more that time is passing and we are getting close to the end of this challenge.  So I started to mount the various project parts together.  Here is a picture of the main unit:     I have built the main unit on a prototype board, which I have placed in a project enclosure that I then mounted in on top of a bicycle helmet.  It is not really limited to bicycle helmets; it can be placed on any sports helmet, and with a custom PCB design it can ...
In the next three days the posts will be about the components of provided and additional equipments. The today's players:   1. AD8232-EVALZ This is a single-lead, heart rate monitor front end is based on AD8232 chip. The functional block diagram is seen below. The measured bioelectric signals are sensed via attached electrodes on the human body. This device can operate with 2 (left, right) or 3 (left, right and driven) electrodes. The two (L and R) electrodes connect to the instrumenta ...

Final Housing Build

Posted by quisss Apr 27, 2015
Well, this actually may not be the final build. I would like to add a shoulder strap, but I am currently strapped for time, as I am in school and finals week is next week. Without further ado:   For reference, one of those floor tiles is a 9 in. by 9 in. square. The 3d print has a few flaws in it, but those are mostly cosmetic. If it were printed on a better printer, the flaws would no longer exist. All I have left is to finish the code, and test which I believe will happen in the next f ...

(Complete list of all blog entries in this series) I have mentioned multiple times that for my project I'm using s PSoC4 MCU from Cypress. But I never explained what is so special about these chips and what made them so useful for my application. PSoC is short for "Programmable System on a Chip". Its a combination of a MCU core with a number of PLDs (programmable logic devices) and programmable analog components on a single chip. In contrast to a "normal" MCU where you write code that executes ...

Title: Total Player Monitoring By: Md. Kamrul Hussain Project Category: Design Challenge Project Name: Sudden Impact Wearables Design Challenge Blog post: 06   Intro:   It's going to be a short blog post today. I am presenting the full circuit diagram for ECG module and the PCB design. Hopefully, I'll be able to develop and assemble the PCB by next week.   About the sudden impact wearables design challenge, I don't have much time left to complete my full design. I am far be ...

Ultimately the thickness of module is reduced so thickness of final wearable stack of all boards will be r ...
(Complete list of all blog entries in this series) I already mentioned that I'm on a business trip right now, so progress was quite slow. I did some work on the PCB, more on that later. Since the trip involved flying over the atlantic ocean, I took only the Pioneer BLE kit with me. The ADXL breakout stayed at home to avoid any confusion at the airport. The goal was to work on the Android application for my phone, to get the BLE connection to he PSoC4 BLE working. Since I had no real accelerom ...
Title: Total Player Monitoring By: Md. Kamrul Hussain Project Category: Design Challenge Project Name: Sudden Impact Wearables Design Challenge Blog post: 05   Intro:      In this blog post I would like to present my experiment on Heart Beat Rate detection from QRS complex of ECG signal. Here I have used a modified version of the algorithm developed by PAN and TOMPKINS [1985] and further described by HAMILTON and TOMPKINS [1986]. This algorithm has several steps - ...
This post is going to be short and sweet.   I got the heart rate monitor working and got the Arduino boards to properly read the input to determine distinct heart beats. Below is a video of the heart rate waveform:   Very soon I will be able to start testing as I am almost done putting this all together. ...

I am back with another update on my "Wearable Sudden Impact and Health Monitor" project.   In my previous update I showed how I improved my Android app by adding a graph that will display the real time ECG measurement.   That time the graph was functional but the hardware and firmware for capturing the ECG was not done yet.   So I started to experiment with the Analog Devices AD8232 evaluation board, which I found extremely easy to setup and use.  In only a few minutes ...

(Complete list of all blog entries in this series) Wow, I just realized that my last update was already three weeks ago. That also means I don't make fast enough progress right now. My excuse? There was a 70th birthday that needed to be celebrated (which also means a gift needs to be prepared properly), and 40th birthday that needed some preparation in advance, a road test report that needed to be written. And I wrote a bandwidth performance comparison between the TBS1102B-EDU and its smaller T ...
