This should be implemented for the next revision of the hardware as a built in.just saying.Nice job!

Hey, thanks for your work! I have a question: in the link with the instructions: low pass filter it says that you have to use a 100 ohm resistor in line with 5v. Did you use a 10 ohm one? apparently the 10 ohm one is for the water resistant one (WR1…

Yeah, this creates a project called ArduCopterMega which use the version 2.0 instead the latest version.

Maybe it's a failing motor in that axis? Jason

jasonshort replied to Andke's discussion 'AutoLevel - how to use it correctly ?'
When you level the copter, it uses the ground as a reference. This is often not enough, so you can fine tune it in the air. Keep it away from ground effect, turbulence, and wind. At about 5ft, keep the adjusting the sticks until the copter no…

SJ1 is the link to remove if powering the APM from an external battery - I thought perhaps that's what Robert was referring to above. Thanks for the info.  I'll give it a go.

where is SJ1? I did this mod Dave and didn't unsolder anything. Just make sure you do the clean cut of the copper trace between input and out put side. I was using the ESC power and it worked fine but now I'm using a separate switching 5v…

Before I do this mod, just wanted to clarify a couple of things: 1. Does SJ1 need to be unsoldered? 2. Can the entire board be powered from the ESCs after the mod or is a separate BEC required?

Yesterday I downloaded 2.2B6 and installed it to the copter. Using Mission Planner version 1.1.31 I generated a tlog file attatched. It flew very well. The Auto mode works terrific using the ch 7 waypoint. During selection of the waypoints…

jasonshort - thanks for sharing your experience. I have added lenses to the flip externally and they work ok, would you mind sharing your lens adaptation for the flip? I have been researching the ardupilot and trying to understand how it might work with our twin easystar - maybe I should just jump in and get it. thanks again for your thoughts.

Hey man wondering if you have flight tested your AIR app yet. Would love to get my hands on the source - even just the artwork, it looks amazing. Great to have another Flash dev on here to toss ideas too.

Dang, Jason, it's windy in SF today! You're a brave man for even trying to fly near the water...

Did you recover the plane? I dunked one a few months ago. Tip: rinse *everything* in tap water ASAP before it dries. Otherwise you'll get corrosion.

Hi Jason,
I saw a post concerning rc cars. Well, that's what I want to do but I now understand that this is more complicated than I thought due to the fact that cars move slowly and the GPS has a hard time with that. I understand that one needs other sensors like magnetometers, obstacle sensors and etc. I was wondering if you have seen a post where some nice person has listed the components used and the codes. I was kind of excited to do this but I'm starting to think that the only way would be to have someone who understands it to build it for me or walk me through it. I was thinking that an arduino controller would connect to the ardupilot and the ardupilot would connect to the RC.
I thought I would ask you if you had any suggestions on this.
Thanks,
Bill Jenkins

Sorry I don't. I would Start with the encoder for the wheels. These usually use a hall effect sensor and a tiny magnet attached to the wheel or other rotating part. Maybe that is a hint that could lead you to some example projects.

Great to see the work in progress. I have a new APM that I bought ready assembled and programmed  few months back, it was a little too unstable for my Flying Camera Mount designs that I am working on. However I have just uploaded the latest code and will be soon giving it another try. My normal test FC is a KK Minso Kim board that has no bells and whistles so I always have a benchmark to test and evaluate the aerodynamics. I then fit a MK board with the full kit. I am desperate to get away from MK and hopefully your code will be the answer. The thing that I thought might interest you is the fact that my MK boards are modified to take 67 deg/sec Gyros as I need to cage the models movements to stay within the 20 deg/sec that the camera mount uses. It is of course a bit risky if the mk gyros saturate as that would lead to a crash but I keep the stick inputs to a very low limit. The fast response and low noise seems to be the key to great stabilisation, plus the fact that the arms are 1 meter across with highly responsive motor/prop combination. The thought occurred that maybe we could develop a super stable version of AMP just for Aerial Video. The 500 deg /sec gyro does have amplified signal at 110 deg/sec but I expect that it will amplify the noise as well.

I see in the wiki that to enable SuperSimple :

"You can enable this option by setting the parameter named RESET_SIMPLE to 1 ( 0 = disabled)"

Isnt the parameter called SUPER_SIMPLE?
