Updates: Devices available and progress during Beta

Devices Available!

10 devices without CO2 sensors (so no soil respiration measurements) are available on publiclab.org (http://store.publiclab.org/products/multispeq-handheld-fluorometer).  We have quite a few more in the works, so if you miss this batch you can catch the next.

New ways to get a MultispeQ


PhotosynQ Share – No Longer Available.

We’ve learned two important things so far in the Beta: 1) We suck at making MultispeQ devices quickly and 2) Most people just need a device for a short time (a month or so).  So we decided to make a lending library for MultispeQs.  Just click on this link, fill out the form, and we’ll let you know if and when we can get you a device.

Mobile Phenotyping Group

Also, we started a crew of fearless data collectors to work with partners here at Michigan State University.  We call these guys the Mobile Phenotyping Group.  We’re working with folks like Marty Chilvers on pest management in corn, soybeans, and wheat, Jim Kelly on selection of the common bean, and a whole bunch of other folks on everything from photosynthesis research to forest management.  If you are at Michigan State and you’d like our help designing, implementing, and analyzing data collected using the MultispeQ please go apply here.

Project highlights

We realize that the site is a bit messy, and sometimes it’s hard to find really interesting projects, so I thought I’d list a few to check out.  Click on ‘dashboard’ to see the raw data and play with it, or the discussion button to see what people have been saying about the project.

Nitrogen Management in CA systems in Malawi (Plant) 11. – This was data collected in Malawi comparing 5 different crop rotation systems with some surprising results (farmer recommendations on which treatment is optimal would NOT be the same for each location!) .  If you click on ‘dashboard’ and map you can see the 3 site’s where the data were collected from.

Testing Parents for Genetic Variation -Jared Crain from Kansas State University was able to identify very small (<3%) differences in photosynthetic efficiency of photosystem 2 between two elite wheat lines.

MSU’s Sonya Lawrence is having her summer biology students create projects – here’s a few:

BS 172 US15 Photosynthetic Activity – [Beta]
Tree Age influence on Photosynthetic rates. – [Beta]
Sugar Tyme Efficiency Sum 15 – [Beta]
I’m going to improve the quality of the projects and the results pages, so keep an eye out for more highlighted projects in the future.

Improvements to Forum

The website forum has been updated, and many problems are now fixed.  You can communicate with other collaborators within your project using the forum, get tech support (we trawl the tech support forum so you’ll get an answer as fast or faster than emailing me directly!) or find others with similar interests.

Forums are located in the Forums tab.

v1.0 update

We are furiously working on the next version of the MultispeQ, v1.0.  We’re getting the first test PCBs out soon, and the case is being redesigned with some important improvements like integrated cuvette measurements (so no separate cuvette holder to install) and integrated leaf thickness sensor and leaf temperature.  At some point in the next 3 months, we’ll give a more significant update on the features of this next version, so stay tuned.
