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

DEF CON Badgelife: Someone Finally Did It

Badgelife is the celebration of electronic conference badges, a way of life that involves spending far too much time handling the logistics of electronics manufacturing, and an awesome hashtag on Twitter. Badgelife isn’t a new thing; it’s been around for a few years, but every summer we see a massive uptick in the lead up to Def Con.

For the last few years, the designers and engineers deep into Badgelife have had the same conversation dozens of times. One person says, “you know, someone should build a badge that’s a quadcopter.” Another person replies, “Can you imagine how annoying that …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

FAA’s Drone Registration System Struck Down For Hobbyists

The US Court of Appeals for the D.C. Circuit has struck down a rule requiring recreational drone users and model aircraft pilots to register their drones with the FAA.

This began when [John Taylor], an RC hobbyist and attorney, filed suit against the FAA questioning the legitimacy of the FAA’s drone registration program. This drone registration began early last year, with the FAA requiring nearly all drones and model aircraft to be registered in a new online system. This registration system caused much consternation; the FAA Modernization And Reform Act of 2012 states, ““…Federal Aviation Administration may not promulgate any …read more

The World’s Lightest Brushless FPV Quadcopter

When a claim is made for something being the world’s lightest it is easy to scoff, after all that’s a bold assertion to make. It hasn’t stopped [fishpepper] though, who claims to have made the world’s lightest brushless FPV quadcopter. Weighing in at 32.4 grams (1.143 oz) it’s certainly pretty light.

The frame is a circular design cut from carbon-fiber-reinforced polymer, and on it are mounted four tiny brushless motors. In the center are the camera and battery on a 3D printed mount, as well as custom flight and speed controller boards. There are a series of posts detailing some …read more

Helicopter Pendulum is PID-licious

If you’ve ever tried to tune a PID system, you have probably encountered equal parts overwhelming math and black magic folk wisdom. Or maybe you just let the autotune take over. If you really want to get some good intuition for motion control algorithms, PID included, nothing beats a little hands-on experimentation.

To get you started, [Clovis] wrote in with his budget propeller-based PID demo platform (Portuguese, translated shockingly well here).

The basic setup is a potentiometer glued to a barbecue skewer with a mini-quadcopter motor and rotor on the end of it. A microcontroller reads the voltage and PWMs …read more

Umbrella Drones — Jellyfish Of The Sky

Mount an umbrella to a drone and there you go, you have a flying umbrella. When [Alan Kwan] tried to do just that he found it wasn’t quite so simple. The result, once he’d worked it out though, is haunting. You get an uneasy feeling like you’re underwater watching jellyfish floating around you.

A grad student in MIT’s ACT (Art, Culture and Technology) program, [Alan’s] idea was to produce a synesthesia-like result in the viewer by having an inanimate object, an umbrella, appear as an animate object, a floating jellyfish. He first tried simply attaching the umbrella to an off-the-shelf …read more
