Article: Simple Raspberry Pi Fun Without a Power Supply

Great article.  My question is the overall merit of doing PoE.  I can get a PoE switch that injects power into the system relatively cheaply, but does it also add noise generally or otherwise degrade other parts of the system.  If its one device, maybe just adding power to the R Pi would be better?  

Hi Mike, there may be many "better" options but it really depends on what one's goal is. Mine was to create an audio endpoint with PoE so I could run a single cable to it (Ethernet) and a single cable out of it (USB). The simplicity is what I want out of this device. I have Sonore Rendu devices for everything else.

 I run a Cisco 2960 switch via poE (from another Cisco 2960 that supplies the power) and it was a subtle upgrade over just the main Cisco switch. The poE switch only carries audio traffic. Worth the $50 or so I paid for a used one.

Are you referring to the 8GB version only? I ordered a 2GB version off Amazon yesterday.

The 64 bit OS is in beta, and that's optimistic.  You might want to read my initial evaluation of it for audiophiles.  It's simply not ready for our use yet, e.g. I couldn't get Roon Bridge to install after an hour of trying Roon's easy install - it throws an error about the ALSA libraries that I simply couldn't decipher well enough to fix.  It's not fully coded for audio or video, can't use VNC, won't run VLC, has an altered root structure for multiple files compared to Raspbian, etc.  I'm sure they'll fix it all, but for now we still have to use the 32 bit Raspberry Pi OS (formerly known as Raspbian).  Click the image to open the thread.

Up and running here.  I used Ubuntu 20.04 and downloaded Roon Bridge.  Using a PoE injector from the B side of an EtherRegen to the Raspberry Pi.  Other than a temporary issue with my DAC (thanks Chris) it's working perfectly, and sounds much better than I thought it would.

Very cool Colin. 

 

Did you use the linked file to quiet the fan noise? Or, did you get a PoE hat without a fan?

I asked about this on your site and the answer was "no plans to do this anytime soon"

Really interested ... one of my RPI4 is already waiting!
