Helicopter POV display is a masterwork

helicopter hack LED mod

Yes! A radio control helicopter with a fairly high-resolution persistence-of-vision display is a beautiful thing. [Mziwisky's] handiwork is the result of several steps along the prototyping path. He built up a POV test rig on a breadboard, designed his first PCB for the project, and then went to work building it. After initially being inspired by a POV ceiling Read the rest

Easy quadrotor helicopter instructions

Here’s a great tutorial on building your own quadrotor helicopter. This build isn’t necessarily less expensive than others we’ve seen since quality motors, propellers, and control circuitry aren’t cheap. But the design and assembly is well documented and presents a well-planned building procedure. The carbon-fiber tubes that make up the frame have extensions to protect the motors and propellers … Read the rest

Robotic helicopter that can grasp a payload

Like the Grand Theft Auto RC missions come to life, this helicopter can grasp objects for transport. They don’t have to be a special size or shape, and it can lift them even if they are not centered. This is thanks to a load-balancing hand (originally developed as a prosthesis) that relies on flexible joints and a … Read the rest

Wyvern quadcopter

[William Etter] and his classmates built a quadcopter as a class project. We love the details of these builds and they came through with some thorough documentation. Some highlights that we enjoyed were reading about ABS body design and construction, their analysis of two versus three blade propellers, and their breadboarded control mechanism. You can see their Read the rest

Aerial photography platforms

[Eric Austin] is using a Canon 7D with this RC helicopter to capture some amazing HD video. His success has manifested itself in a company that is now manufacturing these platforms ready-to-use. Take a look at their blog to see some of the hardware they’re working on, such as a tricopter and hexacopter photo platforms. We’ve also embedded a video … Read the rest

Cell phone chopper control

Control your tiny inexpensive helicopter with a Nokia N900. The chopper uses an infrared remote control, just like a television. Getting this to work was just a matter of figuring out the IR commands and writing an app for the phone to spit them out.
