Overview

Concept

Mitch Altman proposed a Global Hackerspace Challenge and PS:One accepted. The full description of the Challenge is at Global Hackerspace Challenge.

Mission

We are building an array of biosensors as part of our program to:

  1. familiarize people with collecting data
  2. provide useful health related information displayed in a digestible manner to the device wearer
  3. provide larger data samples to medical professionals should the user choose to share what they have collected
  4. promote healthy living and health awareness
  5. encourage hobby electronics by using open sourced hardware


Our initial audience for this device kit will be secondary schools and colleges. It will be marketed as an educational and personal experimental tool. The array will collect data from various sensors attached to the test subject's body and then make that data available to the experimenter. The project will use as many common consumer parts as possible.


A $900 Paypal budget will be provided by element14. The terms of the Challenge require that it use a microcontroller and a "portable power source" bought from element14.

The Team

As of 15 Mar 2011:

Product Line

General Student Kit

for the kids this is the primary kit we are developing for the GGHC.

This kit includes wired sensors and a mother microcontroller enough to get students involved in data logging.

Wireless Student Kit

  • Same as General Student Kit but the sensors are wireless via ardunio minis + xbee shields. Just in case wires aren't your thing.
    • Note: XBee modules have ADC and PWM out so they can act like a substitute for an actual wire without any additional microcontroller. A good option if the remote sensor needs no additional processing at its location on the body.

Expandable Modules

for the Mad Scientists, Cyclists, Marathoners, and Runners.

These sensors and devices are too hardcore to be included in the basic package but we wanted to provide them should you need to take over the world. Most have another ardunio onboard.

Projects and Leaders

properties common to all sensors

This list contains the proposed sensors, in order of decreasing priority. For each sensor, the persons leading the R&D are listed.

  1. Body temperature - Phill, Shawn
  2. oxygen saturation and heartrate - Phill
  3. galvanic skin response - Drew
  4. respiration frequency, and carbon dioxide output - Bill
  5. Respiration Volume - Bill
  6. ECG and EMG - Shawn, Avner
  7. EEG - Avner
  8. Blood Pressure
  9. [3rd Party] Fit bit like device - Eric


The project must also include the following components:

  • microcontroller - Eric, Phill, Drew
  • Mother Arduino - Drew
  • protocol definition - Bill
  • wireless comms (xbee, bluetooth, etc) - Drew
  • data visualization design - Eric
  • mobile device interface - Drew, Bill
  • end-user documentation - John, Eric
  • General Input Device (catchall for sensors that are difficult to monitor, or easier to use existing equipment i.e. logging body weight)

Google Health

Google Health will be used for sensor data tracking.

Videos

We should also include our own application tracking system that replicates Google Health locally in case Google Health folds (unlikely but possible).


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.

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.

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

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
