Hi All, Sony has actually given us something to think about.

The Sony FDR X3000 Action Cam has 4K resolution, but for our use, the BOSS…

Really, really stupid idea of the month, maybe the whole year!- - Drone attack Eagles!

Posted on February 1, 2016 at 6:56pm 38 Comments

I just saw this on our local news and was surprised nobody else had posted it here yet.

Easily the truly stupidest idea I have ever seen - Dutch Police train Eagle to take down drone.

Better than the UnAmerican Eagle in the Our Man Flint Movies (that dates me a bit I'm…

FAA/DOT UAS Registration - A Very Short Window to Comment

Posted on October 29, 2015 at 12:16pm 11 Comments

Hi All,

We have a very short window of opportunity to comment on the FAA's proposed registration process.

I have sent in the following comment which you are welcome to copy, edit, do whatever you want with, but I think it realistically presents a decent case for moderation and common…

Hola que tal Gary sabes el hadware que necesito para hacer mi drone Cooperativo

Hi Gary,

Just a thing on shipping rates (from your comment). I was also mad because of high shipping. I sent support an email and they shipped the parts for free through standard mail! I got it in 2 days ( I live on the east coast). There is a size limit though, can't go above 13 oz, but for small parts its fine. Oh and btw, when you email them, ask for Lorena, it may take a day or 2 more because of her work hours, but she's been amazing with shipping like this.

 

Sorry this is the only way I could contact you!

 

Michael

Hi Gary,

I have read your comments on http://diydrones.com/profiles/blogs/autonomous-camera-imu-based-localization-for-a-ar-drone-quadrotor?xg_source=activity.

I am a student studying on path recovery using Parrot Ardrone2.0 . Is there a way to use its intrinsic sensor to do this? Do you solve it? 

Thank you.
