I made some maps showing how many people have registered drones in every county in the U.S. The maps are based on the data that FAA has made available about drone registration.
You can see the maps here.
I processed the data and made the maps usin

I made a power supply which can produce -12V according to the data-sheet of LM2576-12. The outputted voltage is 24V and the 0.5A re-settable fuse has been used. Occasionally I found a circuit board which exists

I want to try and implement a Neural Network PID controller to a quad rotor. To start I would like to try it out on a simulation. Does anybody have a good python quadrotor model? Also starting out the simpler the better does anybody have a 2D

I have pixracer communicating with my MCU over telemetry using mavlink protocol. I would like to use it in stabilized mode using roll, pitch, yaw and alt commands.
I am able to set the stabilized mode and arm it, however I am not so sure about

I am a doctoral student and in my project I work on control theory. I want to build a simple quadcopter to test my algorithms on. I have an external camera system (motion capture system), similar to Vicon, to estimate the orientation and posit

Is this normal? One time it actually returned home. But ever

Hello,
Thank you again for welcoming me into this group. I love drones for their use w/ videotaping me and my friends snowboarding. Is it true that someday they will replace lift chairs w/ drones someday?
Anyway I have a need for a S/W engineer that ha

I want to use the SET_ATTITUDE_TARGET.mode with a companion computer using ROS, in order to test experimental route planning, any of your know can I do this? I´ve read that since arduplane 3.7 is implemented but I can´t fin it.
Thanks

Has anyone seen a good article that describes the key differences between Fixed Wing ESCs vs. Multi Rotor ESC's?
Also how do you identify them as most suppliers do not mention what they are designed for.
Yes I know people use fixed wing ESC's on Qu
Hi everyone, i have managed to install a pixhawk to my Trex 400 electric helicopter. It flies perfectly stable on stabilize mode however when i switch to rtl, althold or loiter it starts to vibrate in a funny way however it still flies. It can return

I'm interested in utilizing the Serial output NMEA functionality in Mission planner to receive and log raw GPS data. I want to use this approach because we're using RTK GPS, and I want to log additional accuracy estimation data, which is not

We have an uneven pre-landing strip (bumpy, not flat), so the laser range finder will not give usable reading before it is a

Hello all,
I want to trigger my camera shorting 2 wires (soldered to the shutter button of a nex7), and I'm quite lost. Any advice? do I need any extra device or can i just plug it to a pixhawk output port? How to connect?
