Anybody seen this topic?
After 2 years, I finally made myself to properly cleanup the code and build a more stable setup. (Software-only sync was good enough for while)...

Thanks to previous hackers from this forum, I was able to hack/make myself an emitter without even having seen one irl! :geek:
After a few code and platform iterations, here's what I can offer:

Code:
Source available on GitHub
Built using a makefile and avr-gcc. I've used Atmel Studio, but should be possible to use toolchain included with Arduino IDE.
(I can upload a binary, but a lot of stuff is hard-coded...)

Hardware:
(Arduino) Pro Micro. ~5$ for a clone from China
And an IR LED(s) + transistor + resistors combo for actual signal transmission.

In the current state, software sync is not enough and can jitter a lot, SO:
A) Use external hardware sync signal. Currently accepts VESA sync, but with a few changes it can accept raw VSync.
B) Try to tweak backlight strobe and shutter frame timings + duty cycles to minimize jitter for your own setup.
C) Contribute to the project - a timer needs to be setup and kept in sync via the extra USB packet data.

Multiple protocols are already added. G05-A universal glasses that I have seem to support a lot of protocols, including 3D-vision one!
Stay way from Sony glasses, they appear to alternate polarity instead of full-blanking! (Anybody wanna buy a set? :D)

Attached a picture of my "setup":
2 status leds + 1w IR led for wide range, switched via mosfet. (added the 100ohm resistor only for the sake of a safer example)
Sync signal going to pin 2 from monitor (From DVI2LVDS to be exact :twisted:)

Very cool. Wish you or someone else would sell kits for a fraction of Nvidia's exorbitant rates.

Hello, did you include the "full HD 3D IR" protocol?

Implemented protocols (but not all of them) are found in paper "Investigating the cross-compatibility of IR-controlled
active shutter glasses"
I'm not aware of the one you mentioned but could add if given the timings

After more search it appears that full hd ir and rf logo comes from the full hd 3d glasses initiative, that in fact includes compatibility with many protocols from different manufacturers.

So my question was a nonsense.
