DIY Head Tracker For A Tenner

If the button greys out you are not using the latest UI. Pocketmoon PM'd me a link to the fixed version but I've lost it now as I don't get much PM storage on the forums.

I'm using the 9150 code Pocketmoon advised and it feels finished. If I keep it plugged into usb I find the temperature stays up and means just a single 20 second auto-calib. I don't store mine upright so I find the auto-calib necessary.

Would be cool to be able to stop/start the code so that we can stop drift calcs etc when not actively using it but that's all I can think of :D

3.0.5.1 isn't the latest ? Dayum, if anyone have it, can he send me a pm please ? :)

edit : maybe you can upload it on mega or something ?

I only got mine yesterday so only had a couple of hours with it.
I find if I'm on for a long time my neck gets a bit notchy anyway.
Im also using voice attack, so I have the ED tracker SW running in the background and I use voice attack "centre;reset" to reset the centre when my neck starts to go.
This lets me move and adjust my head to a new more comfortable position without having to come out of game or hit keys.
I hope to get a longer up time in today, so I will let you know.
I had mine built in house, so it came ready to go and it is the 9150 model.

Is that running in the background, is there anything else you need to set up in game?

Yes opentrack runs in the background, you have the same settings in game as you do for the edtracker.

I upgraded from the 6050 to the 9150 and using the sketch "9150DMPTest3" - yea, you won't look back - I don't have anywhere near as many problems. Once it's warmed up I take it off my head, rest it on the table and reset it, 20 seconds later I'm good to go.

Try using the "OpenTrack" software as well - this give you the 3rd dimension of roll.. :)

I'm going to retry v2 again. I'm finding 9150DMPTest3 seemingly loses center every now and then. With V2 you went though the calibration process of moving the EDTracker through all extremes/axis. With V3 you do not, and I wonder if that has something to do with it?

I also find if you leave the headset in a direction anything other then upright (ie: as if on your head) it requires a total calibration again (ie: the onboard button).

I'm using 9150DMPTest2, because it's working nicely and I prefer the faster reset behaviour, as I move around quite a bit and the chair is on casters. Never a hint of drift.
Opentrack is essential for custom axis curves and a smoothing filter, so it's now perfect for me and I may ignore all future upgrades on the grounds that if it ain't broke...

I recommend the 9150 version. It overcomes the only limitation of the 6050 version, doesn't rely on lighting conditions or camera quality, and it's not horrifically expensive like *coughing fit*R5. The 9150 opens up reliable headtracking to people who couldn't justify the cost before.

Having said that, I'm dying to spend the difference on a second hand CH Pro throttle now, assuming they go back to sensible prices at some point.

Sooo, I "played" a little with my 9150 today.

First of all, thanks to Blairvoyach, Pocketmoon and all who have helped me on the previous pages.

I made a complete recalibration of 6050 and 9150, using Blairvoyach "procedure". I don't know why, but multiple 9150 calibration seems to not working correctly here (UI crashing etc...). BUT !
After many manipulation, recalibration etc, the tracker can now work barely properly on low range : when I move my head far to the right, the tracker (and my headlook) goes to the left and bounce. But when using opentrack and subtle curve configuration, I am able to use the tracker without bouncing.
With the test3 sketch, this is playable, and no crazy yawing.

I'll do more tests, but I think I'll stay on this configuration since this is working well. :p

hey guys, whats the current lead time on the units atm? friend i recommended to get one placed an order approx 2 weeks ago and not heard anything..

Hi i dont know if its been mentioned b4 in this thread or been looked into but, have you thought about a wireless solution for this tracker? the cheap wifi module (esp8266) may be perfect for this (only 3-4 dollars on ebay) and will connect direct to the UART of the arduino.

there are several models of shapes and sizes but all do the same thing, only some have more io pins you can use, to the point u may be able to omit the arduino altogether.

The V1 model has a 8 pin header, the V3 has a smaller footprint and many more io pins open, and can be surface mounted like many BT modules.
its just an idea but as soon as i saw this thread i immediately thought of these little gems and how they can be used to help make the tracker wireless :)

It's about 3 to 4 weeks if you include the christmas break for those who ordered the other side of christmas. We're fulfilling orders from around the 16th December right now. The reason is simple - we downed tools over the chrimbo period but we also experienced a massive influx of orders, presumably due to the combo of ED release *and* christmas! We're ramping up stock to catch up so it shouldn't be a problem.

There is a "Pro" model in the prototype phases, we are waiting for the PCBs this week to see if it's technically viable, but it does include a wireless option. Then it's a case of whether it's financially viable! People always ask "Oh, should I cancel my order and get one of those then?" so let me just tell you all now - 1, we don't know if the design is sound until we make the first prototype and 2, assuming it works, there will then be a period of time where we need to find a place to outsource its construction, then spend some time refining the code for it, so do not expect it to be ready for another couple of months at best. So if you're still after head tracking and you feel like EDTracker is your thing, I would take a current design as a stop-gap until "Pro" reaches us.

Well I've given up, for now.

Any USB -> micro USB lead I have bought or have been supplied by the EDTracker guys ( great guys and gals btw ) simply generates an error in Win 8.1 stating that the device is not recognised. I have bought four leads so far, and we received a standard USB 2.0 extension cable today that also will not work, not even if I connect the three working cables I have to the extension. The three cables that work are one from a Galaxy Note 2 - 70cm long - one from a Galaxy tab 3 - also 70cm long and one from an old Nokia N8 - 1.2 meters long.

All of the working leads work fine connected directly to any USB port on the PC, connected via the powered USB 3.0 hub on my AOC monitor, or connected via an old non-powered USB 2.0 hub on the end of a 1.5 meter USB 2.0 lead.

All the other new leads will not work no matter what I plug them into, and I can't use the tracker properly with the length of the leads that do work.

A friend suggested it may be the length of the newer leads causing the problem, but none are as long as the lead connecting the non-powered USB 2.0 hub to the PC + the Nokia N8 USB cable combined, which works fine, but is not suitable because the hub is hanging off my head if you can picture that.


Any advice would be greatly appreciated because this has driven me to distraction over xmas.

Just got my 3mtr ANKER micro usb cable from Amazon, works in he pre built unit I ordered.

Can't wait to get mine. After playing with FaceTrackNoIR and being disappointed by how bouncy and unreliable it was, but also getting a taste of the benefits of headtracking, it's really a no-brainer.

Though I just ordered it this week, so it'll probably be a while.

Thanks chaps for your work on this project.

Things have really moved on from last April when I first ordered the parts for an EDTracker.

The components sat in a breadboard for months but signing up for beta 3 prompted me to build a tracker.

The GUI interface is great, loving the additional options over using the Arduino IDE, and after warming up the tracking is really stable with Opentrack.

Also thanks to the chap that recommended the Staples pencil sharpener many posts ago!

I'm a fan of flashing lights so I put the boards next to each other:

to save me searching even more through this lengthy thread, can anyone advise as to why my tracker over recent weeks has decided to develop a twitch?

Its like i move my head rapidly to the right and then back to center in like a second, but i don't actually move physically at all.

using 2207 and ui 304, wondering if it needs another calibration etc doing?

Thanks

I get that on the 9150 with very latest UI - Not sure if this is what everyone else is using as Pocketmoon sent it to me to test.

If I leave my headset seemingly not upright, it gets "confused" and often that results in a twitching left/right.

Sounds to me like a register is wrapping somewhere. Probably to do with the drift compensation value reaching its limit and wrapping over, but not wrapping cleanly. I wonder if there's a ">" instead of a ">=" somewhere....

If someone can reproduce this easily (ie. very repeatable) then I suspect Rob would be interested in some debug data. I've asked for a debug log to be added into a future revision of the GUI so that it can be turned on, left running, and then a resulting log can be emailed to us to figure out what's going on in situations like this.
