Concept

Mitch Altman proposed a Global Hackerspace Challenge and PS:One accepted. We proposed the construction of an array of biosensors which could be used in a secondary school or college setting as an educational and 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 COTS parts as possible. The terms of the Challenge require that it use a microcontroller and a "portable power source".

The full description of the Challenge is at Global Hackerspace Challenge.

All development parts must be purchased using the $900 store credit at element14.

Sensors and their Project Leaders

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

1. properties common to all sensors
2. Body temperature - Phill, Shawn
3. oxygen saturation and heartrate - Phill
4. galvanic skin response - Phill
5. respiration frequency, volume and carbon dioxide output - Bill
6. ECG and EMG - Shawn, Avner
7. EEG Avner

The project must also include the following components:

• microcontroller - Eric, Phill, (Drew - if additional help is needed)
• data visualization design - Eric
• mobile device interface - Drew, Bill
• protocol definition - Bill

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

• Will be setting up dev environment for N900 along with Bill & started reviewing the wireless sensor book as well.
• I wasn't able to attend the first group discussion but plan to be at the space for discussion after the Mar-22 weekly meeting. I'd like to talk with Eric & Phil about the microcontroller selection as I'm interested in that as well as the mobile aspect.
• I'm 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

Eric Hanley

• Freeduino SB Kit acquired, building soon
• if anyone has pictures/graphs/charts from the sensors send them my way

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].
