I'm trying to inject an OSD on a analog video signal.
I've read online about some solutions for that, but none solves my problem. I came across this product Micro Minimosd that only uses an ATMEGA 328P, so i know it's possible.
From what i've read, this product can only output "predefined stuff", i need to draw specific graphics on the screen.
I think something like this woul do what i want SparkFun On Screen Display Breakout, but the product has been discontinued.
I've also seen some shields that do the same thing, but they are way too big, i'm planning to use an arduino nano.
Is there something i can do to accomplish what i need? Preferably with things i have laying around? (mostly basic arduino stuff, an ESP and some logic gates ICs)
I don't wan't to have to order online from china, that usually takes up to three months to arrive.
