DIY Head Tracker For A Tenner

Bahng

B
is there a large difference in yaw drift between polling and interrupt? as it stands now im having to recenter way to much due to a constant drift even if it it small but its enough to have my head go off at an angle to keep center.
i ask since the board im using doesnt seem to work with interrupt, i dont think it has that pin connected since nothing happens after i try and flash the main sketch after calibration with interrupt mode selected, only polling works.

looking at the board i dont think i can add the int connection unless the needed pins are broken out to pads elsewhere on the board. I'll science it and see..

the board in question is from this item using the same chips as the EDtracker:

Hi I want to ask there is way to use EDTracker firmware/sketches upload in to Ed tracker offline.
In other way calibration and setup EDtracker without get up on server I try we can use opentrack and GUI v3.0.4 offline and it work, for calibration and back to GUI do we online server's?

The command-line flash tool can be used offline (if you have an image/.hex file you want to load into it, one that you've pre-compiled). It can be downloaded off the EDTracker website. The GUI can't flash from file, but it should still work for calibration/etc even if you're offline (it will search for the server but timeout after a short while - if not, let us know, that's a bug).

Got all the parts yesterday and after some cursing (was missing the matching button which I did not order since I was thinking I would have lots of them somewhere) I managed to assemble the tracker, found some case and fixed it to my headset. I did go for the 9150 board - but am currently using the non-9150-firmware as that seems to work better. However - quite happy with that ingame and it does work much better compared to the webcam-facetracking which I had tried before.

Just want to make a post to thank Brumster for sorting my EDtracker for me. I messed it up, he fixed it for the price of parts and P&P.

Already grateful for the work done in developing this, even more kudos for being incredibly helpful!

You're welcome dude ;)

Server downtime

Just an FYI for those who've not spotted it, but the website will be down for a period tomorrow (8am GMT onwards) while we migrate to another server with a bit more oomph. We clocked over a million hits in December alone :-S

I would certainly suspect that to be the case, naturally! That and the visitation of a rotund bloke with a beard and a red suit... ;)

So I got this the other day and I LOVE IT. Got a pre-built 9150 and am loving it. I am running into one issue, however, that I'm wondering if anyone could help me with (I did do a search but didn't find a relevant result, so I apologize if this has been covered).

I followed the instructions in the user guide to calibrate the thing, and that worked great. However, when I try to load the 9150 calibration scheme to calibrate the gyroscope, the GUI can't connect with the tracker. Has anyone else had this issue?

Thanks!

My parts arrived this morning, after an hour or so I had the tracker built, flashed and ready to go. I calibrated, did the drift correction and went in to ED to test.

It's so accurate, tracks perfectly and is a joy ( pun intended) to use. Thanks to all involved in the creation of the ED tracker + rep :cool:

Hi, make sure you grab the test version of the UI from https://github.com/pocketmoon/EDTracker-9150/blob/master/UI/EDTrackerUI3051.zip?raw=true

That has support for the 9150 test firmware.

Cheers,

Hey, I'll do that, thank you. Dan has also been helping me. Apparently I did the old method of calibrating rather than the 9150 method, so I'm gonna use the command line to wipe the tracker, then reload the calibration script for the 9150 and take it from there. :)

Peeps!

New EDTracker 9150 (magnetometer) test firmware is available. If this looks good I'll be aiming for a "production" release at the weekend, along with an update UI and full instructions.

Instructions for use for at http://reprapdad.wordpress.com/2015/01/13/edtracker-latest-9150-test-firmware/

Hi Rob,

Ordered mine just before Christmas, damn delivery person put a card through the door today rather than ring the doorbell, so its sitting in the sorting office :(.

I am assuming its the latest hardware (Model EDTTRK002), will I need to update to 9150 would you know, and is it quick to get going from scratch? if its half an hour I might have a go tomorrow, much longer and it will have to wait until the weekend.

Thanks & sorry I can not look through 3k posts. I am like a kid on Christmas eve lol.

I did watch some youtube on it a while back but I think it relates to an earlier version.

Evening, Rob. I have 9150 and didn't know all this testing was going on. You ought to have test info on your website, rather than tucked away in this 227-page thread.

Anyway... I downloaded the new UI, recalibrated and flashed with the test 4 sketch (from the original test 1 sketch) and all looks good. REALLY good. Everything feels much smoother and more accurate with no jumping or unwanted re-centering. Very nice and a very welcome improvement to an already top-rate device.

I have a question - is there a way to lower the sensitivity when looking straight ahead? What I mean is, when my head is facing forward and still, the device registers all the miniscule little head twitches that we're not even aware are going on, and that translates to relatively jerky motion on-screen which doesn't seem to be an issue when looking off-centre.

The obvious answer is to set a small deadzone in the ED settings, but that results in the view 'sticking' and you have to make an exaggerated head move to 'unstick' it. Other apps like OpenTrack, FaceTrackNoIR and TrackIR have curves you can set for this sort of thing.

This is all very subtle, of course, but it's the only feedback I can think to give. The device is THAT good.
