Hi all, long time no post, but this is too good.Those of you doing development want this.At $200.00 it is 3 times cheaper than the TX1 normal development kit/board and the only difference is no camera module, but any USB camera can be used.Not quite the poop of the TX2, but for object avoidance or even…See More

First - You need a lot of light bulbs:

A friend sent me this and it seemed perfect for a little Christmas cheer.

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

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…

H Gary,

First off, thank you for the superb job on the F330 construction page and wiki table of contents.

I will Email you the Image so that you can put it where you see fit.

Many thanks again!

Jethro.

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,

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.
