"i'm sorry but all these comments are confusing... can you update the post with correct binary/value sequence? sounds like the value should be 27 and not 11 in order to have the flashing led ...is that right?"

"I love that the flyer actually thought he could get it back - and get help getting it back - out of a 200 foot deep chemical laden hot spring. Good luck with that. He should be charged as if he dumped a couple of pounds of garbage into the spring."

"Turns out Windows 8.1 will not load an unsigned driver. The only way around this is to use startup options to disable teh check, but that only persists until reboot. Can we get a signed driver?"

New Generation Kinect Available for WIndows Soon

Posted on June 26, 2013 at 3:57pm 7 Comments

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
