Can we get the circuit schematics for this? Or any kind of build plans? Thanks

so…is there anyway to have the output go to stereo speakers that connect with the positive and negetive wires?

I agree what’s the point, when it come to this applications, but there are practical applications. After the tech that took care of a local ham repeater determined the lightning damage to the controller was cause in path by the path to the telephone line. He constructed something similar than this to eliminate wire conductors.

why? because if you’re the sort of person that spends more than $20 to replace the cheap-o headphones that came with the portable cd player (and you probably are, if you bought one nice enough to have S/PDIF interface), you want higher-quality audio than the device’s internal DAC and amplifier will deliver.

Why? Isolation! No ground loops, no EMI in noisy environments. Also a good test rig for checking TOS link connections.

I can’t help but think it would be better labeled as an optical to analog converter, as i can’t think of any other practical use for such a thing.
