I mistakenly ordered a 4S instead of a 3S battery. Given the time it took to come, I am inclined to just keep it.I have a couple of quads that I run on 3S and on which the motors are rated for 3S.…Continue

New Generation Kinect Available for WIndows Soon

Not strictly Drone related, but if the weight and power requirements are manageable, the new Kinect sensor from Microsoft could be pretty amazing as a navigation/obstacle avoidance/3D mapping tool. And it can see in the dark and read your pulse rate.

Hi Scott - I saw a post from you this past year about your uBlox gps not getting a fix. I'm having the same problem and was wondering how you got it fixed.

 

Comment by Scott Berfield on September 13, 2012 at 12:23pm

Just got one of these and cannot get a lock. the fix light never lights, though the power light does and the Planner software sees it. Not super happy after paying $75.

 

 

Thanks!

Turned out it was  abad chip/board. I returned it to 3DR for replacement. The new one worked fine.

Hey Scott, I found your page about Status LED for the APM2.5 and would like to use part of your info and add it to my 'How to" doc. I will mention your name for the credit. Is that ok?

 

Thanks
