  1. mom, i know it's you. You need to stop.

  2. If this is truly low latency, it could also make proper low latency wireless headphones. Bluetooth headphones always have 100 - 300ms of audio lag (even the special low-latency ones), which makes them terrible for gaming. Bouncing an optical laser up to my ceiling & back down again tho, I'd gladly do that.

  3. Yea. Tho as he says: rooms ALREADY have power connections all over the place. So one way of conceptualising this project is kinda like using your home's existing power sockets as your (lossless & lagless) digital audio speaker cables. I agree tho, it seems it could be better if the speakers were passive & the optical receivers were powered by battery, and the whole system sized appropriately for that. Coz unfortunately those optical receivers do need to be powered, the speakers can't be completely passive & wire-free. Tho perhaps it could be powered wirelessly, maybe solar? We're already using mirrors afterall. If the optical receivers are low power enough, an internal battery could last a few days and be charged constantly with incidental passive light in the room 🤷‍♀️. Lots of fun ideas to be had.

  4. No. Wireless is obviously the crux of the innovation being shown here, our modern optical networks are not wireless. Well... Laser satelite-to-satellite interlinks not withstanding.

  5. Laser diodes aren't coherent? What?! They're coherent enough for purpose it seems.

  6. Yeah I do wonder about that. I would have liked to see some sort of audio latency numbers & real comparison, rather than just the "it has no noticeable latency, just trust me dude" explanation. That's subjective 🤔 The transmitters/receivers clearly have microchips, so time is being cut up cycle-by-cycle, some systems do this with a lot of latency & some don't. Point is U can't just trust its good latency, its gotta be checked. Otherwise what's the point, we could have saved ourselves the effort of doing the whole project, by just NOT CHECKING whether the Bluetooth speakers we were replacing had latency in the first place!

  7. -Isn't optical digital? It's binary.- Edit: Ah I see your point, I forgot that he isnt using the existing tv's or amplifier's OWN optical output. I guess he didn't want to modify his existing equipment
