Fidget Spinner Slash Drone is Both

So Hackaday loves fidget spinners and we don’t care who knows it. Apparently so does [Jeremy S Cook], who decided to mash up a spinner and a cheap quadcopter. To what end? Is that even a question? Spinners are the bearing-studded equivalent to the Rubik’s Cube craze of the ’80s and all we can do is embrace it.

[Jeremy] designed a quadcopter shape with a hole in the center matching a VCB 22 mm ceramic bearing he had on hand. He CNCed out the design from a sheet of Lexan resin. Then he detached the electronics amd motors from a …read more

Duocopter Does it With Two Fewer Propellers

Quads are a great ‘copter design. The paired blades counteract each others’ torque, and varying the relative speeds of the four motors makes it easy to steer. But what if you could get by with fewer blades, substituting a significantly fancier control algorithm?

[Dirk Brunner]’s DuoCopter drone uses two propellers that counter-rotate, and it steers by increasing and decreasing the speed at which the blades rotate within a single revolution. Spinning faster on one side than the other makes it tilt. Saying this is one thing, but getting the real-time control algorithms up and running is another. From the video …read more

Manned Multirotor Flies Again, Electric Style

You can’t keep a good hacker down. [Amazingdiyprojects] wants to build a reliable manned multirotor, and by golly, he’s doing it.  After a crash of his petrol powered design, [Amazingdiyprojects] went back to the drawing board. The new version is called chAIR, and is electric-powered.

The flying machine is lifted by 76 Multistar Elite quadcopter motors. Control is passed through 5 KK 2.1 quadcopter controllers. The KK board is a very simple controller, and we’re a bit surprised [Amazingdiyprojects] didn’t go with a newer setup. Batteries are 80x Multistar 4S 5.2Ah packs, stored below the seat. If these names sound …read more
