Lightening Bold Error And Everything Not Fine. #Uselesseater Happenings In #Eurowasteland Galore. Proper powering An RPI.

Been fiddling with a Raspberry Pi 2 for a while now to get the best sound possible to a save-some-money audio system. Even though these little, credit card sized mini-computers are über rocking cool, the only thing I can figure them for is as clients for servers. I currently have two running. RPI 3 is a media client and the RPI 2 is the same, albeit with with a HifiBerry DAC+ Pro is mostly for my audio listening needs. For example, as I worst-write this I’m listening to Robert Plant’s Dreamland. Oh. And before I forget: More on audio on the cheap here.

Although I was able to get the Hifiberry to work from the get go, there was always some software adjustments that it needed and since I’m really, real lazy when it comes to software stuff, it’s taken me a frustrating while to fish through it and not just get some get-go but get it going get-go real well. Which brings me to this post. As you, dear worst-reader, may not note from the pics above, two pics were taken while on a relaxation, i.e. clear head walk in order to figuring out how to configure the config-txt file on both RasPlex and Volumio so that the sound card (Hifiberry) can take full advantage of the RCA cables from it. Then all I had to do was set the client software (i.e. RasPlex) to send 92khz signal (it’ll go up to 196!) through the Hifiberry Dac and bing-bong, whoopsidaisy. Then the next problem.

While on the walk to clear my head, I saw a dead bird and a fishing lure where no bird or lure belonged. The lure belongs no where near the friggin Rhein River where I was walking. In fact, that is not even a river, lake or fresh water fishing lure. But what do I know about fishing–I’m on my third marriage or so? As far as the dead bird goes, I couldn’t help but stare at the thing for a long while wondering if there was a connection. Indeed. I first saw the lure then the bird. On top of that, the bird somehow looked familiar to me. But, like the lure, I couldn’t place it or how it got there. Nomatter.

The remaining pics are from the damaged package I received from you-know-who. I had ordered two 5 volt 3,3 amp powers sources for my RPI/Hifiberry setup. As you may or may not know, RPI require only 5 volts of power. The amperes of the 5 volts, though, determines what you can run with or, as in this case, on the RPI. It seems that the error that I was consistently getting from both RPIs was due to electric inefficiencies. I had been running both PIs using old iPhone USB chargers and whatever USB A to USB micro that I could find. The RPIs weren’t getting enough electricity. These new powers sources seem to have solved the problem. Audio is fantastic. Thank you Robert Plant!

Rant on.


PS Of the USB pic, the one on the left is the proper micro connector. It’s both longer and, because it’s transformer is permanent, seems to provide optimal 3 ampere power to the RPI with the HifiBerry DAC+ Pro, which requires more than an RPI without it.

PSS My next project is to try another RPI 3 with the HifiBerry Amp2.
