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…

Great deal on a 3 axis gimbal with Alexmos controller

Posted on June 26, 2015 at 4:00pm 64 Comments

Just had to tell all of you about this $59.95 three axis gimbal deal on EBay:

This seemed like a great deal and looks to be identical to DYS Gimbal on Hobbyking which is $200.00.

I got one and quality appears excellent though I haven't tried to use it yet (I will probably get…

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.
