Wireless TOSLINK audio. Holy crap, I ran out of desk and it still works. Using two shitty plastic lenses from IKEA lamps. 96kHz 24bit uncompressed. Take that, Bluetooth!pic.twitter.com/Rus4rLaTt8

New record: 140cm. I don't think I can go any further with this setup. The alignment is extremely finicky at this point, and any added loss makes it drop out.pic.twitter.com/AKUEbxKUzN

To give an idea of the margin: at 135cm it sounds perfect, at 140cm I get the occasional dropout, and at 145cm it's unusable.

Brings to mind an experimental cheap optical link I made in my 1960s teen years. Tx was a torch (had to be “on” for dc bias) with an audio amp (>2W) ac coupled across bulb. Rx was OC71, with paint scraped off, feeding amp/speaker. Worked across room, but how things have moved on!
