Looking promising.

For those who have the gps already coded on their audio (ezosd), is there a way to decode that?

I'm pretty sure its not open, so there are two options:

1) Somebody Cracks it.

or

2) Somebody goes up to Sander's House with a shotgun and demands it be released (or someone could try to convince him via Skype or FPVLab).

Great work Jalves, will be following with interest...

Does anyone here know if a decoder is being developed for the MinimOSD? Now that these OSDs [at just $20] & the arduflyer boards [at $89] have been tested & are working well, all we need now is a low cost decoder to grab the data - is anyone here working on this too?

Cheers,
Wolf

Good news, my scope is fully functional again.

So I am working again in my video telemetry project.

You know, slowly but one step each time.

Have you considered how to decode it again?
Fast ADC, some analog electronic and a comparator or something else?

You might be able to AC-couple the signal and just use a comparator to detect black/white (high/low). Just do a quick calculation to get a descent capacitor and resistor-value.

Just curious if you had any cool ideas

Dennis,

I am using a LM1881 coordinated with a LM393 to help decide which is 0 and which is 1's.

Here it is the jig that I am using.

the telemetry pulses arrive timely at arduino port, now how to read them properly is another issue

Just a small follow up.

The opendiyAT has the 1st official byte transferred by wired video telemetry!

Congrats... One small byte for telemetry, one large byte for fpv
