BTW - Are the "9150 testers" still OK with the "test Util" we dowloaded a while ago? Or is it out of date now?Ferrite core will change the distortion of the magnetic field so if you add or remove it then I would expect you would need to perform mag calibration. But if it's working - don't change it
[edit] There are a couple of bugs in the latest (v4) 9150 test sketch which may be effecting you.
The start-up calibration can product odd results. Manifests as magnetometer struggling to keep yaw drift in check (head wobbles a bit). Workaround is to press the button again.
The 'recentre view' code doesn't clear magnetometer readings so pressing multiple times results in a build up of mag compensation errors.
The code which calculates the transformation matrix which "un-distorts" the magnetometer readings can fail if the raw data is too far off centre ( the red sphere is way off).
All are fixed in the production release(... soon)

Further testing reveals that the drift to the left is over about 2 minutes, and it doesn't seem to matter if I have headlook turned on all the time, or turning it on/off a couple of times. If I trigger it on, wait a few minutes and turn it back on, the centre is already 25% across to the left. Repeat this, and it is completely across to the left. If I trigger it and leave it on, the drift is more noticable after a few minutes of using it, whereby I need to look to the right, just to make the unit think it is facing directly ahead.
I have the UI minimised, and the options within ED all seem to be correct.
Using the button on the unit itself to re-centre will work to bring it back to the middle, but the drift happens once again over a few minutes...

Hi,
The value in the compensation field is very high. It should be much closer to 1.0
Can you load the EDTracker2Calib sketch and click Calculate Bias Values (then tweak using +/- buttons to get the gyro and accell values as close to zero as you can ). Then reflash the EDTracker2 sketch.
[edit] while you're at at , go into the windows 'Set up USB game controllers' dialog, double click the EDTracker -> Settings -> reset to default.

There will be a new UI to go with the new "production-ready" 9150 sketch. For 9150 users it removes the need to load separate calibration and main sketches - all in one now. Writing up the user guide at this very moment

Thanks Rob, really appreciate all the work you're putting in.
Considering that at first it wasn't totally clear that it would be possible to get the 9150 working well, it's impressive just from a technical standpoint. My 9150 version has been working so reliably and perfectly on DMPtest2 + OT that I'm slightly reluctant to upgrade it.

Same here with the V4 test version. It's just rock solid, accurate and smooth especially with Opentrack. It's not just E: D either, in DCS, using the same ini I use for Elite, it is just as good.
You never know what new features an update might bring, so I end up updating anyway, consequences be damned
PS:
What's that DONOTUSE 4.0.0 sketch for? I'm sure the name is just to scare us away from the really cool stuff. Pocketmoon wouldn't upload anything harmful. I'm sure of that. Almost

Darn! You see through my thinly veiled plot!
It's always temping to press the big red button that says "NO NOT PRESS"
It over-volts the caps and makes them explode on the Arduino. It's part of our new anti-griefing code; pop a shot on Cmdr Pocketmoon and your head explodes

I've been using my EdTracker (9150) for a couple of days now. Superb. I'd like to thank whoever it was that went to the trouble of soldering it all together for me.
Any idea where else to get the constituent parts? I'd like to put one together myself for my brother and hobbycomponents are out of stock.
Cheers.

Hi,
I'm using a 9150 and calibrated it following this description -> https://reprapdad.wordpress.com/author/pocketmoon/
Works like a charm and is rock solid now!
@bonjour: I ordered via Ebay. Was shipped from China within a week or two.
cheers

Phew, right, there you go... latest 9150 release done, I'm off for a lie-down (as I'm sure is Rob)....!
FILL YER BOOTS!
Big up to Rob and all the guys who've helped test the 9150 code and feed back on it during it's development phase... it's very impressive, I must say...
Just a note to make it perfectly clear - you must use the latest GUI and *please* follow the new instructional document specific to the 9150 for calibration details. It's not the same as before (for anyone using the original 9150 v1.0.0 firmware)...

Superb work as usual guys! Well done!
Just one problem in the PDF, it says to click "Full Auto Calibration" but my button says "Auto Gyro Bias". I assume they are the same as the EDTracker then calibrated exactly as per the instructions.
Once again, thanks for everything you have done on this.
Regards,
Jeff.

Ah, must have missed that re-screengrab. I will fix but yes, it's the same thing. That's my doing actually - I suggested to rob that "full auto calibration" made it sound a bit too much like a magical one-button-does-all so bugged him to rename it.... then I've clearly missed updating the screengrab in the document! <slaps wrists>
Magic! I'm all over this! Re-calibrated and about to fire up ED while the wife and kid are at the nature centre.
Just as bit of feedback, the documentation doesn't quite match up to what's presented in the new GUI. There's no "EDTrackerMag" sketch for example, it's listed as "EDTracker2_9150" in the GUI. Also, there's no "Full Auto Calibration" - it's "Auto Gyro Bias" in GUI.
LOVING your work, lads!
edit! Pipped to the post!
