Google Health
Google Health will be used for sensor online data tracking and records.
We are planning on making a locally run application with the same functionality should the user not want to share their data the cloud.

Biosensor Array Computer Device Interface
A computer will be used to view real-time graphs and logs. It could also be used to enter/edit data manually.
- Processing: good for computer (smartphone?)
- Titanium Appcelerator: cross-platform mobile (bb/andriod/iphone) & desktop (mac/pc/linux)

Mobile Device Interface
A smartphone makes a convenient device to view real-time graphs and logs on the go. It could also be used to enter/edit data manually.
- QML: good for computer & Qt-capable smartphones (android & iphone?)
- Titanium Appcelerator: cross-platform mobile (bb/andriod/iphone) & desktop (mac/pc/linux)

Member Notes
Bill Mania
For my part, I've been re-building my development environment for Python and Qt on the Nokia N900 mobile device. I've also been reading through "Building wireless sensor networks" by Robert Faludi, to get an idea of the wireless options available to us.
Drew Fustini
- Refer to: Biosensor Array-Drew-Fustini-Notes
Eric Hanley
- Tons of Wiki Editing done. Please Preface internal Biosensor links with "Biosensor Array" to segregate our part of the wiki and make migration easier.
- Google Health will be used for sensor data tracking.
- We need to start buying parts ASAP(we're on week 2/5, if your ordering online expect at least 1 week for delivery)
- Freeduino SB Kit acquired, building soon
- if anyone has pictures/graphs/charts from the sensors send them my way
Avner Shanan
- I tried and failed to edit the intro videos we took. For some reason, after transferring the files to my windows laptop, the files only had audio, and no video. I'll be contacting someone with more experience tonight.
- Started building the EKG circuit. I have the first part built, but it's not behaving as expected. More testing and tweaking will be needed.
Weekly Meeting Notes
March 22, 2011
- Drew suggested the posibility of using the Heart Spark as a heart beat sensor
- Discussed approaching the accuracy through redundant sensors that could be averaged rather than high precision equipment (keeps costs down)
- John Stoner suggested we make the project as available as possible, i.e. usable stand alone without a computer, with options for USB and bluetooth connections
- We should decide on a target audience (both for who might use the device, and who might be building it)
- Took some video (high level description of the project, bios for Avner, John, Shawn and Drew) for the introductory post which is due by Friday
- [Drew] Just a FYI disclosure: I confirmed today with the element14 marketing manager running the contest that is ok for me to participate even though I am an employee of Premier Farnell (element14's parent corporation). I just can't be the team rep for Maker Faire if we make the finals [I'll be working Maker Faire for the element14 booth anyways].
March 24, 2011 (Conference Call)
- Brief call between Avner & Drew at space and Bill
- Discussed microcontroller platform, general opinion was to continue exploring Arduino
- believe Eric & Phil already were on this track
- Drew will mail organizers ([email protected]) about parallax co2 sensor to see if element14 can source
- Bill will be working on that sensor
- Avner going to edit video over weekend for first post
- new deadline for first post is Monday, Mar-28
- Drew will write an intro transcript for Avner to record as initial take at Tuesday was too rough
- Agreed best to meet on Tues after PS1 meeting
- hold irc meetings as needed
- possibly explore free conf call service (or skype?)
- Avner going to see if he can get some signal from an ecg circuit over weekend
- design decisions needed to determine if some sensors need their own microcontroller if sample rate too high to have one arduino process all inputs
- good to have local output (lcd?) on the user's body for immediate feedback - instead of just feedback on wirelessy connected smartphone or PC
- Drew is not working on any sensor at the moment, so please advise if help is needed on a sensor
March 29, 2011
- In person meeting at space
- TODO: add notes of the meeting
