SoundMachine Build Log 02

Posted by in Hardware, Tutorial

I’ve decided to put in a knob to control the volume directly on the box itself. It will be controlled by volumio itself via a plugin, much like the GPIO Buttons plugin. Since this is really a development kit approach, the hardware consists of: A KY-040 rotary encoder and A screw-based prototype board Both are relatively easy and cheap to find and buy. Rotary encoder The encoder is straight-forward cheap version, with a push button too, just in case. It’s even mounted on a PCB and has pins too, so…read more

Build Log 01

A while ago I’ve decided to try my hand at replacing my Sonos system with a DIY version of a sound system. I have two reasons to do this: I think it’s going to be fun and I have a bunch of FLAC files at odd resolutions which are not really playable by the Sonos system. After giving it some thought, I’ve settled on the following configuration: A Raspberry Pi A sound card for the Raspberry Pi. For starters I’ll be going with a Chinese clone An amplifier A couple…read more

HifiBerry Pin Usage

Posted by in Hardware, Tutorial

The past few days I’ve been struggling with the unknown of how many pins from the GPIO interface are actually used by the HifiBerry sound card (or my clone). Fortunately, I’ve found the used pins: As you can see, there are quite a few pins left for other things, which means I won’t have to use an arduino to control things anymore :) HTH, A little experiment: If you find this post and ad below useful, please check the ad out :-)

My Raspberry Pi 3 Config.txt for Volumio

Posted by in Hardware

My stable configuration file for Volumio looks like this now: Basics:

Sound card:

WaveShare screen:


The only more convoluted configuration is the networking, which allows me to connect to my wireless network. Once the setup will be stabilised, I will be able to connect it via ethernet, making the whole last section obsolete. And the wpa_supplicant.conf file looks like:

Configure Volumio with PiFi DIGI DAC+

Posted by in Hardware, Tutorial

The other day I’ve got a Chinese clone of HiFiBerry, a PiFi DAC+ v2.0: Here are the steps to configure it with Volumio. First, you need to install Volumio 2 (2.129 at the moment of writing). You need to configure it to e.g. connect to the network, index songs. Note: Back up your config.txt (and wpa_supplicant.conf) Once you’ve got it up and running, select the Playback menu: … and select the Hifibetty DAC Plus for the Output Device and *DAC Model. Make sure you enable I2S DAC: For the options,…read more

AppleIntelSKLGraphicsFramebuffer – Kernel panic with Intel530

Posted by in Hardware, IT

TL;DR: My solution was to just set the DVMT (Dynamic Video Memory Technology) to 64M. YMMV though… Yesterday I decided I want to start building a hackintosh to replace my old mac mini. My system has the following components: Asus Maximus Hero VIII Alpha 16 GB of RAM I6700k Some SSDs, HDDs and a NVMe I chose not to get a graphics card since the nice ones are both expensive (600+ for a GTX1080) and unsupported (there are reports of RX480 working-ish). So, for the time being I’m stuck with…read more

Fix “No Voice” with Kraken 7.1 and VLC on OSX

Posted by in Hardware

Today I had an odd issue with my Kraken 7.1 Chroma: I could not hear the voices in a movie in VLC. I could however hear the other sounds (like the voices were filtered out). I could also hear everything with the internal speakers or one of the monitors… I’ve tried finding answers online but the only bits I could find were for Windows. So, without further ado, my solution is to install Boom 2 (as a trial). I’ve ended up buying it because it boosts up audio nicely. If…read more

Clean Factory Reset for LG G2 (802)

Posted by in Hardware, IT

TL;DR: If you can’t enter recovery (but you can enter download mode) and you’ve installed Lollipop stock back from CM13, you need to erase everything (CSE Flash on your LG Flash Tool). The other day I’ve updated CM13 to a new nightly and it got stuck on boot loop. After searching on the interwebs, I’ve got a final variant on how to make your G2 good again. IMPORTANT! This will wipe your device clean! If you have stuff you want, use something else! Prerequisites Get your phone to accept download…read more

Got an OnePlus Two – Cleaning it up

Posted by in Hardware, IT

Today I got a OnePlus Two without an invite, from one of the many crazy providers with European warehouses. Woo-hoo. Unfortunately, recent reports state they come with malware. Since this phone will not be used by me, I’ll clean it up. Here are the steps I took: Preliminary steps First, booting up the phone. It’s a nice one: It looks like it has some bits that should not be there (floating apps, battery saver …). I do have the android SDK installed, so I do have adb and fastboot. if…read more
