Robb Walters of Flybrix (@flybrix) spoke with us about LEGO-based drones. We graciously let him leave with all his hardware. This time. For a limited time, you can get an Embedded.fm tshirt: teespring.com/embedded-fm. Order by the end of June or miss out. (More info about the shirts.) You can order your Flybrix kit and or read their controller code on github (or their controller app code). Robb mentioned a C++ book he liked, it was Effective Modern C++: 42 Specific Ways to Improve Your Use of C++11 and C++14 by Scott Meyers. He also noted LEGO bricks resale sites: Brickowl and Bricklink. LEGO Digital Designer looks like a fun way to design builds. Cascade PID controllers are on Wikipedia (though I found this tutorial a little easier). The congratulations offered at the top of the show were to Meshpoint.me for winning the Best Humanitarian Tech of the Year at the Europas Conference.
