    Make Faire wrap-up and updates

    by  • June 2, 2014 • 0 Comments

    Maker Faire wrap-up Phew… 48 hours normal hours and 24 standing-on-your-feet-talking hours later and Maker Faire is over. We met hundreds of people, got to use the MultispeQ about 200 times (good opportunity to test the heck out of it), saw lots of other awesome projects like Manylabs, Nerds for Nature, Fusion, Pinoccio and...

    Maker Faire: Day 1

    by  • May 17, 2014 • 1 Comment

    Robert, Sebastian and I are here at the Bay Area Maker Faire in San Mateo. We spent the day today getting our PhotosynQ booth ready, and putting last minute touches (well… more like frantic last minute working) on the experiments we’re running during the Faire. Since it’s late and I’m sleepy, I’m not going...

    Great news and less great news

    by  • January 20, 2014 • 0 Comments

    You can select any two variables and compare them on the X and Y axis.  This makes it easy to identify relationships between variables, and between populations.

    The Great News Increased measurement accuracy by over 100 times You heard right – 100 times! Our old detector was actually pretty capable – we could see even very small changes in absorbance like ECS (electrochemical shift) measurements which the vast majority of other handheld fluorometers don’t even attempt to measure. But the new...

    Chlorophyll content measurement for PhotosynQ

    by  • December 27, 2013 • 1 Comment


    Hey folks – just wanted to give you a quickupdate. I’ve made several improvements to the Arduino code in the last few days so that it’ll be easier for users to create new protocols! We’ll have a few measurements before the start of the Beta. Often called SPAD, this measurement was first commercialized by...

    photo by David Kramer Update The last 2 months have seen a flurry of activity. We’ve gone through a several more iterations on the hardware, and we’re now pretty happy with the quality of the measurements and the amount of noise in the signal (see more below for specifics on that). We’ve also been...
