Creating The World’s Most Efficient Quadcopter Drone
Although not a typical focus of people who fly quadcopter drones for a hobby or living, endurance flying has a certain appeal to it for the challenge it offers. Thus, as part of his efforts to coll…
Autonomous Boat Plots Lake Beds
Although the types of drones currently dominating headlines tend to be airborne, whether it’s hobbyist quadcopters, autonomous delivery vehicles, or military craft, autonomous vehicles can ta…
Making An Aluminium Foil Glider To Prototype Hydroforming
Hydroforming is a very effective way to turn a ductile metal like aluminium or stainless steel into a specific shape, either using a die or by creating a closed envelope in which the hydraulic flui…
Saildrones Searching The Sea For Clues To Hurricane Behavior
Hurricanes can cause widespread destruction, so early forecasting of their strength is important to protect people and their homes. The US National Oceanic and Atmospheric Administration (NOAA) is …
Watch This RC Jet Thrust System Dance
An EDF (electric duct fan) is a motor that basically functions as a jet engine for RC aircraft. They’re built for speed, but to improve maneuverability (and because it’s super cool) [jo…
A Deep Dive Into Quadcopter Controls
In the old days, building a quadcopter or drone required a lot of hacking together of various components from the motors to the batteries and even the control software. Not so much anymore, with qu…
Mega-CNC Router Carves Styrofoam Into A Full-Size Flying Delorean
When you own an enormous CNC router, you’ve got to find projects that justify it. So why not shoot for the sky — literally — and build the 1980s-est possible thing: a full-scale f…
Drone Motion Capture, The Open Source Way
If you want to do some really advanced flying with drones, you typically need to be able to track them in space. [Joshua Bird] has whipped up a drone tracking system that can do the job for as litt…
Variable-Nozzle Ducted Fan Provides Fluid Dynamics Lessons
Any student new to the principles of fluid dynamics will be familiar with Bernoulli’s principle and the Venturi effect, where the speed of a liquid or gas increases when the size of the condu…
