Wish to extend a massive congratulations to DIY Drones - Cross Country Trust Flight - Using Pure Telemetry

Firstly I wish to convey my highest appreciation to all the developers and members of this community.

For those who do not know us, i wish to make a small explanation as why i am posting this.

Im my/our line of work, i/we have worked (and still do when required) on high end Mil spec UAV/UAS, and we wanted to do a mission not dissimilar, to what is required in real world situations.

This is the…

Developer
Ardupilot 2.6 MediaTek Parser

I have a quick beta of the MediaTek GPS parser for Ardupilot 2.6. Quick caveat - I don't actually have this module in my hands yet! I just modified Jose Julio's parser to match what 2.6 needs and read the data sheet on the new protocol. So, if someone who has the new modules could try this out and let me know if you are getting the right values, I'd appreciate it!


Set your GCS_PROTOCOL to 4 in your header…

ArduCopter beta flying!

Here's one of the first test flights of the ArduCopter quadcopter setup, from team leader Ted Carancho. Try doing that with a Parrot AR.Drone!



This is using the ArduPilotMega hardware (APM board and IMU shield) on the original AeroQuad platform. The ArduCopter platform is in final design tweaks before it goes into production. The merger of the AeroQuad and ArduPilot Mega software is going well and a public beta is probably a few weeks…

Flight Control Board trial run. part3

Testing Item:

1.Kalman filter for attitude estimate.

2.900MHz,2W RF datalink.



Although the sensor board not be modified for GPS and airspeed sensor. but I have tested the attitude estime via Kalman filter and RF datalink first. It's sad that I forgot take DV to record it. Orz



The RF made in Taiwan is stable and higher data rate that CL4790.(I have both). But It need specific command to sent data. It is not suitable for general purpose.…

Multiplex Easy Star UAS Configuration

Introduction

I am acquiring a Multiplex Easy Star to learn to fly, and to work on a UAV build. This blog post highlights my proposed configuration, which is to be incrementally upgradeable



I plan to split up my project into five parts:

  1. Learn to fly,

  2. Fly with a camera payload (just for fun),
  3. Fly manually with sensors, a data logger, and maybe a camera,…

This week in unemployment











It's the National Ignition Facility, the most powerful laser in the world. $4 billion. 500 Terrawatts. Enough power to feed 413,223 time machines. It requires 5 hours between each 4ns laser firing to cool down.





It was too windy to get very high. Only got 1 shot at 400ft. Angle of attack got to the abort limit where GPS could be lost & conventional control… Continue

Three more autonomous flights with MatrixPilot

Hi guys,

Today MatrixPilot controlled three more autonomous flights. All three flights were executed with the transmitter turned off. The picture above is the track of the first landing. It was aiming for the midpoint between the two fields, along a line that connects the centers of those two circles.

Recently I posted three flights of my GentleLady flying…

Simulation, taken to the next level.

Hi guys,


I finally decided to join the community with my first post, enjoy.


My work started with great inspiration of the 6.th round of the T3 contest, where the task is to simulate a flight, writing DIY Drones. While the description of the open loop, nor the closed loop simulation did not include any real sensory inputs, I decided to setup a small test scenario on my desktop. I…

ArduIMU/Ap test platform ready!!

Hello all,



Developers of this combined project, Thanks!



Ugly and dirty, the system is ready to roll tomorrow, the bench tests all went well, although I think that the elevator amplitude (gain) isn't enough when in stabilize, which probably will happen also with RTL mode.



More to come, tomorrow.…

EZ430-Chronos as Telemetry system



Hello,

Some month ago TI developped a watch based on there super low current 430 ic,

in it you can find a µc, a triple axis accelerometer, a pressure sensor, and a 868Mhz RF chip with antenna.

they also give the sdk for cooking custom apps...
