Fix Empty adb devices -l with Samsung S9 (and S9+)

TL;DR: Clean up any mobile phone drivers you have and install Samsung’s ones. I wanted to update to the beta UI package. One method is via ADB sideloading, which I prefer compared to SD Card mounting. I started with:

on my system and everything was nice: I hot my phone in recovery mode. I […]

Messy rig

My current rig has: 1 x Vega 56 blower 1 x EVGA FTW2 1070 3 x RX580 Nitro + 1 x RX580 Red Devil It’s nice and I can mine either Ethereum with the hybrid Claymore miner or ZCash (albeit I still need to tune it because it crashes). Unfortunately, the airflow is messed up: […]

Vega 56 and ETH – Keep Your Cool(er)

Following my writing, I’ve rearranged my rig to have the Vega card on one edge (where the intake fan would get “fresh” air from the room rather than heated air from one of the other cards). Results are quite epic. With the settings: Frequency % = 0 Voltage control = manual, with the last 2 […]

Vega 56 and ETH – Keep Your Cool

TL;DR: Keep your Vega cool if you want high hash rates! Recently, I’ve got a AMD Vega RX 56, to see for myself how good it is on mining. If you ignore the power consumption, it’s quicker than my RX580 cards. I’m getting 33+MH/s consistently: At the beginning of the session I even got 36MH/s, […]

Mining Rig Build Log – 1

I’ve decided to join the recent trend of mining cryptocoins with GPUs. First, I got a GPU (an EVGA 1070) to complement my 970 and stuck it in my desktop. This is nowhere near profitable because I’d have to block an I7 machine to mine on 2 cards, and also get annoyed because I can’t […]

SoundMachine Build Log 02

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 […]

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 […]

HifiBerry Pin Usage

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 […]

My Raspberry Pi 3 Config.txt for Volumio

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 […]

Configure Volumio with PiFi DIGI DAC+

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 […]
