Thus far in our development cycle, we’ve been taking a fairly cautious tack on our releases. As in, we’ve given out the code and schematics to those who asked, with caveats about how well they worked. Why did we do this? As a scientific data logging platform, we wanted to make sure that everything to be deployed in the field would be rock-solid and tested before folks we didn’t know beforehand started using our work.
No longer! Thanks to lots of hard work on our part and enthusiastic support from collaborators who have tested our prototypes, we feel confident in releasing all of our schematics and source code! Our hardware source files are all released under the Creative Commons Attribution-ShareAlike 3.0 license. All in-house software/firmware is released under the GNU GPLv3. We also released our modification of Eric Ayars’ excellent real-time clock library for the DS3231, which we spliced together with the object-oriented DateTime framework of Jean-Claude Wippler (JeeLabs) and Limor Fried (Ladyada).
So go ahead – download our code, use our schematics, ask us questions, and help us improve the state of open-source environmental data collection.
