Fancy LED lighting option for your flying machine

Today I spotted this "Digital Addressable RGB LED with PWM waterproof flexi strip" from Adafruit.

Each LED in this strip is individually addressable, meaning you can set the colour and brightness of each LED separately.

Imagine the…

Infrared beacon guidance for the arducopter

Following Leon's great blog post showing the use of a camera from a WII remote as a 3D position sensor for his helicopter, I've been tinkering and now have a…

Optic flow and the Franken aeroplane doing aerobatics

Australian scientists have developed a novel autopilot that guides aircraft through complex aerobatic manoeuvres by watching the horizon like a honey bee. Allowing aircraft to quickly sense which way is up. By imitating how honeybees see, engineers and researchers have made…

It's not unmanned but it is electric flight!

On August 12, electrical/aerospace engineer and helicopter pilot Pascal Chretien took to the air in the world's first untethered, fully electric manned helicopter flight in a prototype machine that he designed and built almost entirely by himself within a 12 month development period. In his 2 minute, 10 second test flight, Chretien beat aviation giant Sikorsky…

Attack of the birds

Today's Arducopter flight got some attention from the locals

A flock of Galahs was grazing nearby when my Arducopter took off. It wasn't long before the Galahs took flight, formed a squadron, called "Tally Ho", and proceeded to chase down the interloper.…

Creating an I2C sonar for Arducopter

I've created an I2C digital signal sonar module to avoid the noise problems I have been having with the current analog signal sonar module.


Seeing all the problems we are having with noisy sonar data got me thinking

Where does the noise come from? Is it:

  • RF noise from the ESCs affecting the sonar module directly…

ArduIMU groundstation written in 'processing'

I have created a basic 'ground station' for the ArduIMU in the 'Processing' IDE

The Processing development environment is very similar to the Arduino evironment

Processing compiles into Java, it allows you to run the same code on Windows, Mac OSX and Linux.

Being a Mac user and suffering from not being able to find and run the correct version of the NI LabView runtime engine I decided to have a go at creating a ground… Continue
