Reader [Chris Rybitski] had a pair of RCA IR headphones laying around from the Radiohut. He’d never really used them and decided they would be much better suited as a wireless audio bridge between his computer and stereo. Since it was going to be a permanent installation his first task was to find a wall wart to power the receiving end. He then reboxed the receiver in an old laptop battery case with the IR LEDs from each ear and an output jack for his stereo. Not to complex, but I’m sure the system works a lot better now that it is in a fixed position instead of strapped to someone’s head.
