EDTracker in use for BMS 4.33
-
Received my wireless today. Will try this weekend!
-
…ooooooh…forgot about the wireless one…I have a wired one…I better get off the stick!
-
Forget it Stevie, at least until they get certified by the USA for wireless transmission. Im waiting on that for a long time. I have the wired pro version and its a bit fiddly to set up with the freeware camera software, but it works nice. Its biggest draw back is no zoom axis (for wired or wireless pro)
EDIT: time to eat my own words…

03/08/2017 - USA orders are go! (not yet for Cannuks)
FCC certification is with us!http://www.edtracker.co.uk/
Note they have a new websiteOrdered mine with tracking for $89.23 (66.35 quid)
Guess ill have a wired EDTrackerPro for sale now. -
I am considering making my own version, using the firmware used on the no-drift headtracker project for FPV RC planes.
Found a link on how to flash HC-05 with RN-42 but this is piracy. But a $20-ish RN42 should allow you to make a $30-ish diy wireless version that uses bluetooth, and hevaes like a HID device (joystick)

Got mine to canada last week. I have to admit that I’m a little bit disapointed.
Drift problem, unaccurate when you have to click in the 3D pit, need to make the “0” very often (too much), etc…
Its installed on the top of a cap.
Goupil send me his curves. Its better now for the movement but still innacurate and drifting…
-
I made a video on youtube of my problem…
-
Try aligning it lying flat and static on a table top, and not on your head…if you haven’t done that already. I did that with my wired one and it seems to operate fine.

I done many calibration, auto bias, always on a table that’s why I’m a little bit disapointed about the precision of the system. Hope to be able to find a solution soon… My patience begins to be short.

Interesting…can’t see why the wireless version would act any different from the wired. Unless there really is an RF or magnetic interference issue. Have you checked that you are using the latest firmware?
-
I open a case on the edtracker website and someone answer me and try to figure whats happen. Will tell you whats happen next.
-
I have the same issue, but noticed only yesterday, and I have edtracker from some time. The only change I have made (in hardware) is that I replaced my headphones with a new lighter. Will do some more test.
-
What does the manufacturer ED Tracker say about this?
Is there settings in the software to affect the drift or return to zero?
-
Unless there really is an RF or magnetic interference issue
Look up how magnetical gyroscoping sensors (MEMS), work - if you dont shield them with diamagentic materials - RF/EM radiation IS a problem (drift and centering-issues). Nothing what can not be fixed with a little DIY.
-
That’s what I thought…so, it could be possible that for us pit builders that are using PWM lighting or other interesting sorts of power sources (like 400 Hz/3-phase?) that we might see some effects within/near our cockpit setups and need to chase some gremlins. Hope not…but maybe?
I’ll have to watch and learn…once I get that far.
-
would have to get some specs on the sensor used in EDTracker… but again…nothing what can not be shielded simply with dia-magnetic coating on the casing etc. and probably grounding would help too.
that a onboard (close) wifi transmitter will fook with a magnetically VERY sensitive sensor … is just logic. they need to be cased and isolated apart from eachother. something the EDTracker builder probably has not considered - yet. feel free to give him that tip. -
I know that for another point there will be a lot of steel in my cockpit - all of the Pegasus structural parts are steel, and therefore magnetic in nature. So I’ll be caged in the stuff. But can possibly compensate during alignment? Dunno…may not be an issue, time may tell.

This topic takes me back to my college days…
If AS is correct, then Mu-metal foil (EMF shielding) or screen or coated material to make a Faraday shield is the way to go, but might not be practical for this application.
An inexpensive workaround would be heavy aluminum foil as shielding material. But as Archer has said, a farady cage must be grounded… a single point ground, that shares the ground plane of the electronics being shielded. Also be careful to not let the metal shield touch the electronics.
First i would make sure the EDTracker is calibrated as required, to emiminate internal drift, noting there is a different procedure for the MPU-6050 and MPU-9150 devices.
An important task before you use your EDTracker is to calibrate it. Failure to calibrate the device can result in inaccurate responses and “drift” over time, where the output of the device slowly creeps in a direction (typically left or right) separate to the position of your head - which can obviously be quite disconcerting!
Secondly, the mounting instructions are clear that stability is configuration dependent
Mounting Orientation
You must set this value to match how you have a ached the EDTracker device to your headset. We advise you to place EDTracker on the top of your headset, with the USB port to one side. Choose the corresponding orienta on in the UI.
WARNING : If the Moun ng Orienta on se ng does not match the actual device orienta on, strange behaviour may occur!Thirdly, which wifi channel you choose for the wireless tracker can affect stability
You can select one of 28 different wireless channels to use. From the factory, the device will use channel 1. You can change the device to another channel if required.
During normal opera on, the number of illuminated bars on the wireless graphic relates to the quality of the signal. 3 bars indicates excellent quality, down to 1 bar showing reduced performance -
You can shield the sensor from “electro-magnetic” radiation (EM in quotes, because that term as it stands is in fact like saying a “pregnant baby”…anyways…) …with simply grounded and conductive materials - preferable with high mag. Resistance (Permittivity) and low mag. Capacitance (Permeability).
If you want to go a step further and be really “anal” about it and shield the sensor from earths magnetical fields aswell, well then you would need dia-magentic materials (Pyrolytic carbon, Bismuth etc etc).
I had for long the suspicion, that MEMS are prone to EMF corruption … even had a chat with someone who filed a patent on that matter (dont ask, long story) … but the reports here, that the WIFI version is lesser accurate confirms my suspicion in a way.
I see big potential in that market tbh. with newer, more optimized and more miniatur-ed versions.

You sound like an EE Archer. I know the type.
Btw, your FCC3 is well cared for.
