Welcome to DIY Drones!

Welcome to the largest community for amateur Unmanned Aerial Vehicles! Use the tabs and drop-down menus above to navigate the site.

This community is the birthplace of ArduPilot, the world's first universal autopilot platform (planes, multicopters of all sorts and ground rovers). Today the Pixhawk autopilot runs a variety of powerful free and open UAV software systems, including:

  • PX4, a pro-quality copter, plane, rover and VTOL software stack from the Dronecode Foundation
  • ArduCopter, a fully-autonomous multicopter and heli UAV system
  • ArduPlane, a pro-level UAV system for planes of all types
  • ArduRover, a fully-autonomous ground-based vehicle system

I'm new to all this--where do I start?                   Are amateur UAVs legal? (yes)

Open source underwater glider

Posted by Alex Williams on October 15, 2017 at 5:30am 2 Comments

I thought people here might be interested in a project that I’ve been working on for a while.

There are no affordable extended duration underwater exploration projects and I’ve developed a hardware platform to provide this capability. The glider uses a mixture of 3D…


Generator on the drone, kickstarter project, test flight and new sketch of the gas generator

Posted by Nicolai Valenti on October 13, 2017 at 12:23pm 5 Comments

Okay, there is so much stuff in the title so let's start with the generator on the prototype 

This is the prototype, the generator is only for demonstration purpose because the generator at the moment is made from a nitro engine with all the connected problems (vibration and fuel consumption). A good thing…


What is the key to designing a High-Performance UAV?

Which is the key to designing a High-Performance UAV?

Answer: Extreme customization of the battery pack with high-energy density cylindrical cells!

We can maximize the performance through engineering a very custom battery pack. This is the key to develop a…

Today, I’ll tell you more about the 18000mah 6s, which is the updated version of our TATTU Pluse. Tattu pluse 2.0 smart battery.

It’s specially made for agriculture spraying, aerial photography survey drones and some others. Because of the stable discharge curve and super large capacity, it provides you long enough flying time for most of the tasks.

It has 6 cells, it’s a quite large battery in terms of the 18000mah capacity. Comes with 15C discharge…

In this article we’re going to take a look at some of the data collected in the new report from Skylogic Research on the drone industry—data we think is important to you and answers the…


Project log: Autonomously returning a glider from the stratosphere!

Posted by Tarik Agcayazi on October 10, 2017 at 12:39pm 9 Comments

Our High Altitude Balloon (HAB) project aims to return the electronics on board a weather balloon autonomously instead of drifting away on a parachute. My Project Log series aims to provide short sweet and to the point updates to said project. Heres the most recent one:

Heres some background:

Is it possible to beat drone jammers?

Posted by eUGENE on October 9, 2017 at 3:30am 28 Comments

Hi everyone,

I just made a bet with some local professional jammer manufacturer who is too confident with their product. 

I'll take them out if I can manage a flyaround over their premises.

Their product is no joke though. As far as I could understand, it scans the entire spectrum and jams the suspectable frequencies but obviously there's something more to it which they won't tell me.…

Thirty two hour flight record for Aerovel Flexrotor VTOL

Long range and endurance are capabilities not often associated with VTOL aircraft. But Aerovel’s unmanned Flexrotor, a unique miniature tailsitter, is cut from a different cloth. Last week a Flexrotor named for the sea nymph Actaea lifted off into a grey and rainy morning with 7.5 kg of fuel onboard. It transitioned from hover to […]

Integrating Drone Technology into Your Business Is Easier Than You Think

The benefit that drones have for a multitude of different industries is overwhelmingly apparent to the technology-minded employees of a company, but negative connotations associated with terminology – and a lack of understanding from industrial decision makers – is holding back realisation of the full potential of this disruptive technology. Ranging from search and rescue […]
