Biosensor Q & A

Posted by Drew Fustini May 19, 2011
Howdy,   Our biosensor array team was recently featured on the Make blog:   http://blog.makezine.com/archive/2011/05/gghc-semifinalist-profile-pumping-station-one.html   I really liked the answers that team member Shawn Blaszak wrote up but unfortunately they didn't make it into the Make post, so I figured I would post them here.   1. What was it like working on the GGHC challenge?   ANSWER:  Working on the challenge has been a lot of fun for me.  My mo ...
Howdy,   Our biosensor team is honored to be selected a finalist and humbled to be in the company of fellow finalists, Hackerspace Charlotte's Feltronics & BuildBrighton's Phonicubes.             I had a total "WOW!" moment when I realized, while watching the Feltronics video, that the circuit on the white board was a radio transmitter!  I think Feltronics will be a big help to electronics instruction everywhere including at hackerspaces.  And ...
Howdy,   The primary sensor I've been prototyping for the Pumping Station: One Biosensor Array is the galvanic skin response, or GSR, sensor.  GSR is a measurement of the electrical conductance of the skin.  Sweating causes changes in the conductance, which offers an indication of emotional excitement, because the sweat glands are controlled by the sympathetic nervous system.  GSR does not offer a fine grained indication of emotion, since it does not distinguish between the ...
Working feverishly down to the wire, we posted our final project status over on our own hackerspace blog and emailed our final documentation to the organizers in the nick of time.   Thanks so much to Mitch Altman, Mark and the rest of the Silverfox crew, and element14 for this wonderful opportunity!   Jordan Bunker, PS:One founding member & ReMade producer, was most excellent to stay up late with our biosensor team and took some great photos during our final integration demo (he ...
Our biosensor array team worked late into the night on Saturday at Pumping Station: One.  With the hackerspace challenge build deadline on Tuesday night, it's definately crunch time!   Thankfully we've got a nice array of working sensors (in the order of signal speed):   EKG Pulse oximeter GSR (Galvanic Skin Response) CO2 Temperature   Dan yet again played the role of test subject:   The QRD1114 sensor from SparkFun contains an IR LED and a compatible p ...
