###What is it? As a smaller, more regular meetup than the annual [Public Lab Barnraising](/wiki/barnraising), we're doing a series of local meetups in Somerville, MA. These include short presentations, open working time, and workshops on Public Lab projects and anything related. ###When/where Parts & Crafts: 577 Somerville Ave Somerville, MA, 02143 Map: http://goo.gl/maps/obVrM ###Toolshed Raising II: Feb 2, 2014 The first "toolshed raising" was [a big success](/notes/warren/12-11-2013/spectrometry-sample-extraction-at-the-parts-crafts-toolshed-raising), so we're doing another, also at Parts & Crafts! Katie G suggested the following agenda: 1. **First hour-- 12-1 pm - Intro to the toolset! --- Not sure what a spectrometer is or why you might want to take photos with the infragram? Come by and find out! First hour is "intro to the toolset" -- we'll have a bunch of stuff out to play and work with -- DIY spectrometers, infragram cameras, balloom mapping stuff and more -- with staff on hand to explain how things work. 2) **Show and tell - 1-1:30 -- Don Blair and co. do a quick presentation on the [Mystic River Open Water](http://publiclab.org/wiki/open-water), a cool new project pairing up with [MYRWA](http://mysticriver.org/) to develop low-cost water quality sensors for the Mystic River to test everything from salt run-off to sewage in the river. They're going to talk a little bit about what the project is, what they've done so far, and how you can get involved! 3. **Open hacking session: 2 - 4 pm.** Come and work on whatever! We'll have a bunch of tools out for people to work on and play around with. Interested in finding "that person" to talk to to get your air quality question answered? Have a cool project to share? Want to hang out and build on stuff? This is your window. Second half is for building and talking and eating pizza and trying stuff out.
