I have a "copter" of some description, except the whole thing spins. There's the central little body, two wings (at 12:00 and 6:00 say), and two arms with small props (3:00 & 9:00), which thrust horizontally, not vertically. Hovering is...a challenge.
My first thought when I got one of those boards was to build a quadcopter, but then I decided that was too conventional, so I elected to build a tricopter. The three motor setup makes yaw control a challenge, as it is coupled with the other degrees of freedom, but that was to be part of the fun. Not gotten very far along, I'm sad to say.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
