In all the tutorials I've seen for making sound card DACs, I see wires being soldered to some connections to the back of the board. Would using the headphone jacks with a standard 2.5mm connector work the same?
I will be building a single color projector on a tight budget for a senior project and writing the software for it from scratch. It looks like I will be using a laser with TTL modulation. What kind of modulation does the correction amp use?
