My first quad(8). H design.

After 6 months of watching the rest of you, I finally had a free weekend to begin the build of my own ArduCopter. I really was inspired by Markus's H-design of his eight engine quad copter.

 

When I checked the store, they only had four of the 2836's but after I ordered 30 more showed up instantly so I…

TRI Trial #1 - Successful enough for now

I couldn't get the software serial to work properly, so I am sharing the serial.

This does mean I have to remove the signal wire from pin 0 every time I want to download a new program, but it's doing what I need.

1) Reading the ArduIMU+V2's data stream

2) Sending to the PC for a bit of feedback

I'll be picking up a MEGA soon...



Today was the first trial of the TRI, purely to see if it could lift off, cancel yaw, and maybe stabilize the platform… Continue

ArduCopter factory updates

 

When we started to make DIY Drones ArduCopter frames and parts we could not foresee the surprisingly strong market demand that existed for this product and the very positive response of the DIY community.  Almost from the beginning, we have had a difficult time keeping up with the ever-larger orders…

HK GCS now with Heartbeats and Link Lost Warnings/Alarms









You can now define how much time passes before a warning or alarm is shown on the GCS by clicking File, Settings and selecting the Alarm and Warning Timeout on the General Tab. There is also an associated speech event for both warning and alarm as well. You can use {alarm} and {warning} as replacements in the speech string.



For example:

DANGER! DANGER! Telemetry link has been lost for more than {alarm} seconds

{alarm} is replaced with the… Continue

Reduced Yaw Drift / Fast Gyro Sampling with the UDB / MatrixPilot



Reduced Yaw Drift / Fast Gyro Sampling with the UDB / MatrixPilot from Pete Hollands .

[Note: Apologies for the low sound volume in this video. Please turn your volume up.]

This is a demonstration of the reduced Yaw Drift which is possible when sampling the gyros at 30,000 times / second (Thanks to William Premerlani for this R&D and code).  Using QGroundControl and…

Melbourne UAV meet

Hey All, with the outback challenge preparations for 2011 about to heat up, the upcoming Australian air show ( http://www.airshow.net.au ) might provide us a great opportunity to meet up for some pizza/hot-dogs and a catch up.



If anyone’s interested we’ll organise a time and place, hopefully sometime during the week of the air show (1st – 6th march), whether it’s inside the grounds or just at a local…
