−
Mitch Altman proposed a Global Hackerspace Challenge and PS:One accepted.
 
−
The full description of the Challenge is at [http://www.tvbgone.com/downloads/hs_challenge/hs_challenge.htm Global Hackerspace Challenge].
 
−
 
 
−
=== Mission ===
 
−
We are building an array of biosensors as part of our program to:
 
−
# familiarize people with collecting data
 
−
# provide useful health related information displayed in a digestible manner to the device wearer
 
−
# provide larger data samples to medical professionals should the user choose to share what they have collected
 
−
# promote healthy living and health awareness
 
−
# 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 [http://us.element14.com/ element14].

Python and Qt on the Nokia N900 mobile device. I've also been
 
−
reading through "Building wireless sensor networks" by Robert

* Todo: write an intro transcript for Avner to record as initial take at Tuesday was too rough
 
−
* Todo: setup dev environment for N900 along with Bill
 
−
* Mailed organizers (hackerspace AT element14 AT com) about parallax co2 sensor to see if element14 can source for Bill
 
−
* Reading Oreilly 'Building Wireless Sensor Networks'
 
−
* Sensor help?  I'm not working on a sensor so any that needs help please let me know

* I'd like to talk with Eric & Phil about the microcontroller selection
 
−
* I'm [http://www.element-14.com/community/people/fustini fustini] on element14 Community - add me as a contact if you'd like after creating a profile; I'm very familiar with the site so please let me know if anyone has questions

== Weekly Meeting Notes ==
 
−
* March 22, 2011
 
−
**Drew suggested the posibility of using the [http://sensebridge.net/projects/heart-spark/ 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
