The latest trend in camera products - modular cameras - is good news for us as drone users.

With Sony releasing products such as the QX100 and QX1 it seemed like high quality alternatives to the gopro we're becoming available.

Now with Olympus and soon Vivitar being the latest companies to add their own modular camera to the list, it looks like 2016 will be an interesting year for modular camera technology.

Balancing Carbon Fiber Props : The Right Way!

A DIY Magnetic Prop Balancer!

In my zeal to get started on my first multirotor I forgot to add a prop balancer to my cart! So I set out to make my own out of parts I had laying around...



My first prototype used a wooden drill bit because it fitted my prop perfectly at 6mm in diameter. Unfortunately because of the shape of the drill bit it would tend to one side, rendering any balancing done…

Graphics for Wiki Documentation

Here are the individual graphics I have drawn that depict 3DR Gear as well as standard radio control components. They are in PNG format and I hope that you guys can find it a useful resource for your own documentation purposes.

I use Paint.net which is a free program and I have never looked back! Here is an example of what you can do with the…

French teenager in court for this video...

This worries me because I currently living in France and am nearing the completion of my first quadcopter. French laws are known to be difficult to navigate at best!

It raises an important question: What does the future hold for small UAV technology in Europe?

From the article here:…

Pixhawk Infographic

Hi everyone!

I would like to introduce to you the final "Pixhawk Infographic" that I have been working on for a while now... it illustrates some of the tips I have learned over the past few years and shows the components that I would like to use in my own personal quadcopter design.

For the full resolution image please go here (thanks to Gary McCray):…

Pixhawk Graphic for Documentation

Here is a sample from an "info-graphic" that we are currently working on for the new Pixhawk flight controller.

Knowing how daunting it is to gather enough info on a new flight controller (to be able to get into the air) I want this graphic to give a clear overview of the main components in a typical "quadcopter" system, from the Battery Warning Indicator…

Dissent in an Open Source Community

I can't help but notice that allot of time in the discussions on DIY Drones is spent arguing. Clearly this saps the energy of this community. It is best never to get involved. That being said I think everyone who is active in any open source community (not just owners) should watch this video.

HD FPV system now being prototyped!

This is what I have been waiting for!

Unfortunately the price might be an issue.

Here is their products page. I am glad to see that this is being considered for multirotor applications. It looks to be a rock solid system and will open up live HD transmission for news and sporting events.…

A good resource for learning arduino on a budget...

I have posted the second video in the series as the first is REALLY basic stuff! 

The great thing is that they have a virtual Arduino uno which you can experiment with to start understanding the code.

 

The virtual Arduino uno application can be downloaded from…
