  Wireless audio using lasers is super simple to actually implement for DIY audio projects. Leave some usage ideas in the comments! Also, don&apos;t forget to check out the LTT screwdriver: <a href="https://lmg.gg/perksdriver">https://lmg.gg/perksdriver</a> a fun fact is that this video concept was inspired by Linus&apos; woes with his wireless surround set a couple of years ago so they&apos;re a fitting sponsor.

  DIY Perks is the only channel that can go dark for months and then drop the most absurd Dr. Doofenshmirtz style gizmo I’ve ever seen.

  I love how you always make these projects so accessible. Piggybacking off an existing, widespread standard. Off-the-shelf electronics components. Simple construction with well thought-out parts and budget. Used in an interesting way. Truly remarkable

  As an AV technician this is, with zero hyperbole, the coolest thing I have ever seen. Seriously, absolutely blew my mind. I&apos;d love to see some more AV or even home networking/automation projects on the channel

  Matt, this is beyond brilliant — it’s SPECTACULAR! As a retired home theater designer, I spent many, MANY hours trying to come up with a good way of doing wireless surround speakers and never accomplished it. Your solution is so elegant and creative. You are a truly astonishing maker. Your channel never disappoints.

  Bro... These aren&apos;t &quot;weekend projects&quot;. This is next level engineering and EXTREME attention to detail. It&apos;s art! <br><br>I lose my mind assembling Ikea furniture, let alone trying to do anything remotely like this. Lol! <br>Nothing but respect to you, sir. Every project you do is just wonderful.

  Laser SPDIF, acyrlic speaker stands dual purposed as transmission lines, 3D-printed 35Hz, and an ultra-low directivity anti-comb filtering center channel?... insane. This is one of your coolest projects yet 🤯

  Absolutely incredible. One correction, those HDMI to analogue audio converters do not support lossless audio, they only support compressed lossy DTS and Dolby AC3. So even though your stereo toslink signal is lossless, you are hearing the lossy stream from HDMI. I am yet to find a HDMI to RCA converter that supports, DTS-HD MA and Dolby True-HD, so the only option for lossless audio is an AV Receiver with analogue pre outs.

  <a href="https://www.youtube.com/watch?v=1H4FuNAByUs&amp;t=341">5:41</a> &quot;this requires some assembly, just like this segue to our sponsor, LTT!&quot;

  You had me at &quot;inserting a piece of milk bottle plastic over the toslink connection to capture/ focus light.&quot; Mad. Can&apos;t believe that works to be honest, would have guessed there would be diffraction and just muddiness of digital signal... and fail. But no. This is SO creative. Chapeau.

  Kudos! &nbsp; Back in the mid 1990&apos;s, I was Dir. of R&amp;D for an audio company in Canada &amp; had worked out a way to do optical feed to remote speakers (including surround/satellite speakers of course) but with the added bonus that the power management was also optically fed to a photovoltaic compact management system within the loudspeakers in order to perform in 100% wireless mode.<br>The biggest drawback at the time was that Class D amps monoblocs, were not very good sounding (although promising prototypes were available for a price) and also the battery &amp; capacitors banks required to power up a nice sounding Class A/B amp for a few hours (about 5 hours per listening sessions before it was drained as it could draw power faster than it could charge unless one was willing to go obscenely big on the power management system specs &amp; cost) was pretty cost prohibitive &nbsp;&amp; relatively bulky.<br>With today&apos;s class D monoblocs, a few good modern batteries (probably mixed with a few caps &amp; even SuperCaps for power peaks if need be) I recon I could bring back the concept &amp; &quot;modernize it&quot; to make it affordable &amp; smaller / less bulky with a much more competitive price point. A cool curiosity &amp; niche product for very peculiar clients that could be fun and, just as your project here, a nice conversation starter. :) <br>Anyways... So very nice to see what you have done here. <br>Again: Kudos!
