DIY Perks video: DIY Surround Sound... USING LASERS!

Just build the mirrors into the ceiling crown molding :cool:
 
I'll pass lol. They covered this on AV Rant basically pointing out all of the potential issues and shortcomings. Props for effort and execution - but not really practical to solve the wireless transmission "problem".
 
Ignoring placement issues - very cool....but


for me, the biggest issue with active speaker surround sound is power. In my house none of the rooms have power sockets in all places where surround speakers would be needed. In my current "cinema" room there is only one set of sockets in one corner. So then you are left with running power cables instead of speaker cables.

So for me, rather than lasers it would make more sense to run a combined DC power and signal connection - perhaps with the SPDIF signal modulated on top of the DC power.

But then - bugger it, you might as well just use passive speakers :)

Or use PoE for data + power, at least for surrounds it should be more than enough?

Ethernet = buffers = latency.
 
Hello,

I am really interested in the project of DIYPerks as it could be an alternative to my own DIY WiSA project.
However, the main cons for me here is that the setup presented in the video does not support Dolby ATMOS (DD+).
To solve this issue, an HDMI Audio extractor compatible and able to decode Atmos would be required and I can only find one product in the market that seems to do that:
OREI 4K 60Hz eARC Audio Extractor - Youtube presentation here However I am not 100% sure that would work because this device is described as 'Atmos passthru'.
If it were to work, it would need to be combined with a HDMI 7.1 to analog like this ?

Does anyone has any experience with that ?
Otherwise, another solution would be an a Dolby Atmos compatible amp with pre-out but these are expensive.

None of those devices will do Atmos decoding. One of the reasons Atmos compatible AVRs are expensive is they are paying for the Dolby licensing.
