looks good - you could make it even small going smt crystals - something like this - http://www.mouser.com/Search/Product...5-ABM3-8-D2Y-T

what are current component sizes?

Quick question: What do I need to get started? I see a lot of different directions, but I am looking for a simple direct solution. The SimpleOSD is sold out but I wonder if there are similar plug and play solutions. I am not a Hardware Guy but more Software ..

Thanks,

Andy

I already have a few of the SMD-crystals laying around, but I don't have a "soldering tweezer" at home. Sure, they can also be soldered with a normal soldering iron, but with the normal crystals being cheaper as well, I decided just to use them.

As it's just a little hobby-project that will be soldered at home, I have mainly used 0805 for easy soldering. A few 0603 0.1 uF caps and some 1206 caps for video-AC coupling and Vcc.

They will not be for sale, they will just be made "for fun". The hardware is pretty much the same as Remzibi, MinimOSD etc. so you are probably better off just buying a cheap MinimOSD from Ebay or similiar.

I only make them as I like DIY

Can you use the MinimOSD with your firmware?

The MinimOSD seems to have no connections, like for GPS, etc. How do you attach these devices to it?

Don't really know MinimOSD, but it looks like RX/TX is available for GPS. Only thing missing is current-sensor and perhaps voltage-sensor.

But this wasn't really planned to be a new OpenSource project. The code was written in a day and pretty hard-coded for my need

The MinimOSD uses a MAX7655 so the code is not directly compatible.

So I read a lot about the whole OSD world but as I said, I am not a Hardware Guy - more Software Guy .. what do I need to get started and how would I integrated the LM1881 chip? Are there any drawings available? I am have no problem with soldering and reading circuit diagrams - I am just not the guy who can put the chips together :-)

Any direction would be appreciated.
