volume control - linear - pro-audio style

Ever thought about volume controls (VC)? 

...how they work? 

...digital volume controls in particular?

or... 

...do you simply slide your VCs up'n down enjoying the sound level getting up'n down !?!? 

Audio meets IoT (DIY)

I am running RPis and (HAT) DACs for years by now. One thing's been bothering me all the time. 

The powering scheme. The handling of it to be exact. I've still been pulling plugs all the time for that very purpose. Pulling plugs in a lab is one thing, doing that in a living room is simply not acceptable on the long run. How do you tell your wife or kids how to turn on that DIY monster-stereo !?!? Push that plug, next this one and finally that one. Simply not possible.

I finally thought to get some Wifi controlled mains plugs in place. Neither Dect, infrared nor bluetooth controlled devices made it on my wishlist.

Let see what IoT (Internet of Things) projects are offering...

RPI - All lights off

I just thought it would be nice to share with you

how to get a lighthouse tower like the RPI to pretend being dead.

Unfortunately even the most current RPI operating systems 

doesn't offer such a trivial and nice tweak via user interface. 

That leaves us only one option: Commandline intervention!

 

CD - RIP

(Latest Update: Oct-2020)

Anybody out there still ripping CDs? Or is it just me. ;)




Recently I figured that some tracks were missing. No idea when and why this happened. OK. Quick decision taken. Re-Rip the affected CDs. Yep - I still keep my CDs in the attic.

Gee Wiz... Re-Ripping a track "quickly" turned out into a major exercise (nightmare).

This article gives some background info and directions related to CD ripping and CD tagging.

networking - RPI dongle your net

I'd like to share an - IMO - nice alternative network setup solution for the RPI3 (It'll also work on the Pi Zero).

The solution will nicely add to, or you might also call it  - enhance -, earlier described networking solution.
