I've been playing with the FPV video modules and wanted to overlay my callsign on the video stream. There are cheap, small, arduino-based boards "MinimOSD" that also are for drone FPV. The firmware for these is open source and very feature-full, but most of these features aren't needed just to overlay a callsign. So I took the https://github.com/ShikOfTheRa/scarab-osd firmware (others seemed not to compile on the current arduino environment) and gave it a very substantial pruning. The result is here: https://github.com/rufty/CallsignOSD
Here's how I boxed it up, pending addition of an amplifier module.
