Logging airspeed on 2.74 onwards...?

Started this discussion. Last reply by Andrew Rabbitt Feb 6. 2 Replies

Does anyone know which parameter group I can find airspeed to log (passively). I have looked in CTUN and NTUN but neither appear to have this listed. Any hints and tips here...?

APM in a 250

Started this discussion. Last reply by Rob_Lefebvre Jan 20. 8 Replies

The crazy man in me is trying to stuff an APM into a cheapie HK250GT as a method to waste an inordinate amount of time. (and likely also money) It is a great lesson in weight reduction and…Continue

Arduino/Ardupilot IDE "hangs" whilst attempting to complie

Started this discussion. Last reply by Andrew Rabbitt Aug 9, 2013. 1 Reply

I'm trying to compile a (very) subtly modified version of Arduplane 2.74b using the IDE downloaded from the Arduplane website (1.0.3) but it hangs when I try to compile.  Actually, it doesn't hang…Continue

Does anyone know any way of mapping the servo mid and end points that APM uses?I have modified elevons on my Skyfun which, unfortunately, have a limited down travel.  If the elevon servo forces it…Continue

Mechanical Engineer with more than a decade in electronic engine control development and application in the OEM sphere. I am a lapsed PPL(A) and currently an experimental aircraft builder (Van's RV-8). UAV's are a fascinating diversion from rivetting...
Please tell us a bit about your UAS interest
Inspired by press articles earlier this year on near-space ballooning, I would like to one day send a UAV glider aloft for a positionable return to land. I'm sure others have similar ideas.

Telemetry Radio Range testing with home-made dipole antenna

Posted on April 28, 2014 at 11:10pm 14 Comments

On Sunday I spent the morning self-consciously traipsing around my brother's neighborhood with an apparently wierd collection of hand-held electronics and foam in the form or my APM, battery and a Hextronic 3DR knock-off 915MHz telemetry radio and Skyfun fin. We left a laptop on the top floor of the house running APM Planner with the base station radio connected directly to the USB port and using a standard "duck" monopole…

Mercedes Benz vision systems research

Posted on October 4, 2012 at 9:30am 4 Comments

I saw a feature about Mercedes-Benz collision avoidance vision systems research on the Telly here in Germany where I am at the moment. 

 

This particular project uses two cameras to create stereo vision.  Comparing the two images is used to detect pixels that represent motion that could be hazardous to the vehicles current path.

Mould Plug CNC Machining for HDwing4

Posted on May 24, 2012 at 10:03pm 5 Comments

Since the topic of CNC mills has raised its head here, I thought I'd share this with the DIYDrones community.

One of the things those who are considering this need to be aware of is that the toolpathing of complex shapes isn't a trivial exercise.  I would be interested to know if anyone has experience with any open-source surfacing toolpathing packages - please comment below! 

I am fortunate to have access to MasterCAM V9 - old-fashioned as it is - but…

Andrew - Thank you for commenting on my BLOG DIY Passive Gimbal.

How about whacking four free-spinning electric motors on it? One flanking each axis? Just so it is balanced. Would they cancel eachother out? Or would making them spin CW / CCW to each other be better?

Hello Andrew! Thanks for the support, and offer. I will definitely keep you in mind if anything comes up. The Idea behind the albatross is open. By this I mean, it has specific goals and design elements, however in the long run I would truly like innovations to be customer based. For instance, If customers started laser cutting their own internal storage shelves/formers, and/or other mods, such as a dome/nose adapter.

If the Pro version every comes to be, I will definitely be needing some specific arts, such as retaining clamps and rings for easy quick-release style components.
