MAX7456 OSD Break out board.
I was going to try to build and design my own OSD a year ago but never got around to it. I got a MAX7456 OSD board for it, soldered on male headers pointing down. It works just fine, I was able to use the test code with an arduino duemilanove to get all the characters on my screen. The only thing is, the C_Out trace lifted up so I had to solder on a tiny strand of copper wire. It test good for continuity though.
Spark fun wants $39 for it.
I wouldnt mind selling this for ~$25 or trade for FPV parts.
