Hi All!
My wish is to overlay readings from built in sensors in my submarine such as port motor speed, port motor temperature , starboard motor speed, starboard motor temperature, water temperature, compass heading, torpedo status (green for torpedo read, red for torpedo already fired), missile status, depth, sound selected, bow plane angle, stern plane angle, rudder angle, pitch angle, roll angle, battery voltage and current, and a warning if water were to get into the water proof housing with all the electronics. It would be great to color code all the readings such as red for port reading, green for starboard and other colors for the other readings. I have a periscope that uses an NTSC color camera.

Best, Ed

Well I was looking into this for a project, but didn’t get to use it:
https://www.maximintegrated.com/en/p...s/MAX7456.html
I edited it above because it’s not only a monochrome overlay, but also I don’t know if it will ruin a colour source video.

Have you searched Hackaday for a project like that?

The video at the link http://www.mikroe.com/click/osd/ looks like color video input with that 7456 chip on the module.

Thanks guys!
The 7456 chip is a "monochrome" chip so text is only in white.

Sorry i missed the color txt comment twice. Will the bob-4 do color txt? http://www.decadenet.com/bob4/bob4.html

I wish it could and sadly the BOB-4 is only white characters. Eagletree makes a text inserter with color text however they will not disclose how to talk to it.

Best, Ed
