Building mavlink in scilab code block
Started this discussion. Last reply by Venkat Gidda Jan 23. 4 Replies 0 Likes
I am attempting to build the mavlink library in a scilab block to run SITL.When scilab compiles, it only finds the mavlnk headers if I name the absolute directory. Changing the working directory…Continue
Vario for glider pilots using mavlink/mavproxy telemetry

If anyone is interested in adding a vario (audio beeps depending on rise/fall rate) for mavlink connected autopilot, there is a project here:…Continue
30 minute timout on Xbee link. Anyone have this problem?
Started this discussion. Last reply by Sgt Ric May 26, 2012. 3 Replies 0 Likes
I have had several long flights when the Xbee 2.4GHz S2 communication stopped around 30minutes after power up. This may be something to do with ubunutu/netbook settings instead of the Xbees. I…Continue
GCS with second monitor output for HUD (not FPV)

I would like to be able to fly while watching the aircraft but still get critical flight data such as attitude and airspeed. This means putting the display in the field of view without obstructing…Continue

Fair comment. Looks like I have volunteered to do the job it before I do any more complaining.

Matthew Coleman commented on Hooks's blog post APM 2.5 from hobbyking"This is really not so difficult. We are talking about a credits page with a link in obvious places. Being difficult to do is a lame excuse for not trying.
Again, it does not matter if you think that people are satisfied not…"
Matthew Coleman commented on Hooks's blog post APM 2.5 from hobbyking"Monroe,
There are two sides to showing clear recognition. One is the obvious gratitude towards the contributor and the other is educating the community.
We have been around this community for a while. We understand who the…"
Matthew Coleman commented on Hooks's blog post APM 2.5 from hobbyking"Stephen, You can go back to playing with your toys once you have found out who took the long hard hours to build and test the firmware and hardware."
Matthew Coleman commented on Hooks's blog post APM 2.5 from hobbyking"Putting OP and it's issues aside for a moment. I am not dismissing them, I just wish to discuss a different angle.
Most of us are proud engineers that like our good ideas to be used. Having our ideas plagiarized hurts, especially…"
Matthew Coleman commented on Hooks's blog post APM 2.5 from hobbyking"Chris: I agree that they should not copy without credit.
The ArduPilot/Copter/thing claims to be community created but it is not really clear who that community is. You are selling electrons and giving bytes away for free. Where are you…"
Matthew Coleman commented on Hooks's blog post APM 2.5 from hobbyking"Would that be profiteering from other peoples effort. Can't help feeling that DIYD and 3DR is tasting some of it's own medicine here. Did the profits from ArduThing ever reach the hands of the original innovators and hard…"
Matthew Coleman replied to Dr John Lannigan's discussion Crius and twin rotor UAV"You need specialist mixer for that. Ardupilot doesn't support it unless you write your own code."
Matthew Coleman commented on Chris Anderson's blog post ArduPlane home page"I correct myself, it reads "a pro-level UAV system for planes of all types"."
Matthew Coleman commented on Chris Anderson's blog post ArduPlane home page"Interesting claim on the front page that it "is suitable for all planes". I guess it is of you modify the code and hardware enough."
Matthew Coleman commented on Matthew Coleman's blog post Anything you want mixing"The udb4 is very much alive. It doesn't have the shiny look and user features of ArduPilot. It does have a team making many innovations that contribute to ArduPilot. ArduPilot is stuck with old methods because that is what the overweight gui…"
b nevins commented on Matthew Coleman's blog post Anything you want mixing"I didn't even know people were still using the UDB4 anymore. It's good to know it isn't a serious load to the system either, I was figuring the extra calculations and functions would be an issue, but I'm not really familiar…"
Matthew Coleman commented on Matthew Coleman's blog post Anything you want mixing""Since all mixing is moved to the Tx"
should read
"Since all mixing is moved to the autopilot""
Matthew Coleman commented on Matthew Coleman's blog post Anything you want mixing"Thanks for sharing your mixing problems. You seem to have a fairly unique setup there. It is just the kind of problem I created this mixer system to solve.
Since all mixing is moved to the Tx, no mixers are needed on the Tx. I fly…"
b nevins commented on Matthew Coleman's blog post Anything you want mixing"No doubt mixing can be complex. I am having trouble setting up mixing on a wing, and it only has 4 servos.
Elevon mixing (Finally added to the APM in manual mode)

Anything you want mixing
Posted on May 16, 2013 at 3:10pm 5 Comments 4 Likes
I would like to introduce the community to a mixer method used to fly complex aircraft in manual, fly-by-wire and autonomous modes.
The main challenges of mixing are:
- Flexibility to do anything you want.
- Easy to use and prevents…

Airspeed control is critical when flying sailplanes. You want to fly close to stall but never beyond it, since that will normally cause a tip stall and great loss of energy. How do you teach an autopilot to fly on the edge of stall?…

This is the Vladimir models Graphite 2e. It is a fairly typical skinny, lightweight, efficient fully moulded motor glider. Despite its 3.1m span there is not much space for anything.
