samples
Just attempted to order a whole bunch of samples from Texas Instruments. They gave me a big f.u. last time. But fingers crossed again. It's really exciting because I found some really cool sync chips.
Progresssss
ooooh under 2g 
It looks good, but I'm a little sceptical about the ability to run on 3.7v as claimed, if only because it's running the MAX7456 which doesn't run on anything under 4.75v as says here: http://datasheets.maximintegrated.com/en/ds/MAX7456.pdf
I nearly got the barone osd circuit going last night. Still some flickering & some guesswork, but almost worked using the demo script. I think the BaroneOSD is the way to go for truly lightweight, 3.7v, and to make yourself at home (diy).
It looks like more & more people are looking into micro-quad osd's which is great news.
Doodled this circuit just earlier. Should be accurate, and as tiny an osd as there will ever be:

update
There's also this that is interesting me:

£12 from here
- 10DOF modules (three-axis gyroscope + triaxial accelerometer and three-axis magnetic field + atmospheric pressure)
- Chip: MPU6050 + HMC5883L + BMP180
- Power supply :3-5v
- Means of communication: IIC communication protocol (fully compatible with 3-5v system containing LLC circuit)
- Size: 2.2cm * 1.7cm
It would mean the possibility of having an artificial horizon

Using the 5v booster idea, there's also this (more costly) possibilty of SimpleOSD:

SimpleOSD = £25 (plus import tax & postage) (£40)
Booster = £1
BMP180 = £2
= £43
More costly, but 4g in weight (as opposed to 8g & £13 of the Minimosd)

benbojanglesosd update
So, here is my progress in my benbojanglesosd experiment.


I'm finding it quite demanding, but I'm making advances. For someone who has never made an electronic circuit before, I'm not doing too badly
Anyway, I have learned now, that there are stages/sections to this circuit.
-The Arduino: prints screen text
-LM1881 part: syncs/strips vsync data (somehow. I'm not fully understanding of it yet)
-Camera: displays screen video
I am not sure yet if the LM1881 is supposed to V-sync arduino data, camera picture, or both?????
I learned, that if I just connect the arduino signal + camera video using a composite splitter adapter into the monitor, the picture is very very flickery.
So I guess that the LM1881 removes either one or both signal's vsync to allow both to merge. But I still don't get this part, or how to link the LM1881 correctly.
It honestly feels like learning a foreign language sometimes, or how I imagine people with dyslexia feel when trying to understand data. I think, as I usually do, that the project isn't fully understood by my brain properly yet - because it's not been laid-out in a way that my brain can understand it yet. Ugh!
Anyway, here's the video of it so far:

Update..
Hugely impressed with the OSDongs progress. Such fluidity:
But not for our ghetto v929 quad
