"The word is,it plays Quake 3 on 1 watt of power.   They are still shooting for a $25 USD pricepoint, with an ethernet jack for $35.  Are there any UAV tasks that warrant this kind of horsepower?   "

How to make a more stable UAV plane platform.

Posted on March 14, 2009 at 4:57pm 6 Comments

Ever heard of "Moment of Inertia"? Neither had I, but it's quite simple really.



Object with the most of it's weight at the center of it's gravity is easier to rotate than one with the weight on the outer edges. So why put all the electronics and batteries in the center under the wing. By distributing the weight to the wings, should create a platform that has steadier flight characteristics.



More on this and a few pictures in my… Continue

OpenWrt UAV platform

Posted on March 9, 2009 at 8:48pm 7 Comments

My idea is to use OpenWrt + Arduino for a futureproof/scalable UAV patform. I'm planning to do some testing in the spring with the basic Fonera router flashed with OpenWrt Kamikaze 8.09.



This setup however doesn't have USB-ports that would enable live streaming webcam, 3G modems and in-flight high quality images through gphoto2 and a digital camera. I'm waiting to see how much the just finalized Fonera 2.0 with USB costs, but I'll still probably go with the… Continue

Hi Pekka,

You mentioned that you used an Accelerometer on your previous message. Which Accelerometer were you using? I am looking for a two-Axis if you know of any with simple installation process. I am tying to test the accuracy of the result I have obtained for the tilt compensation.

Thanks
