Multirotors, or drones as they’re popularly called, are so ubiquitous as to have become a $10 toy. They’re no less fun to fly for it though, and learning how they work is no less fascinating. It’s something [Science Buddies] has addressed in a series of videos examining them from first principles. They may be aimed at youngsters, but they’re still an entertaining enough watch for those of advancing years.
Instead of starting with a multirotor control board, the video takes four little DC motors and two popsicle sticks to make a rudimentary drone frame. Then with the help of dowels and springs it tethers the craft as the control mechanisms are explained bit by bit, from simple on-off motor control through proportional control to adding an Arduino and following through to how a multirotor stays in flight. It’s instructional and fun to watch, and maybe even for some of us, a chance to learn something.
We’ve had multirotor projects aplenty here over the years, but how about something completely different made from popsicle sticks?
To sum up, now let's stop for a moment and consider that camDown FREE helps stop hackers from getting access to the sensitive documents that I use for my work. Now I can get even more gigs as a freelancer and - advertise that I have top security with even my home computer!
