Today I got finally the DeConz stick to control my first smart bulb, am OSRAM SMART+ RGB one. I’ve set up a number of simple tasks to do via the Home Assistant: Toggle the light on and off Set the light with a colour Set a different white temperature for the light My first attempt […]

apt-key adv – Fix ‘Server indicated a failure’ on Raspberry Pi
I’ve been trying to install snips.ai to play with speech recognition. Unfortunately, when executing: I’ve got the following error message:

gpg: keyserver receive failed: Server indicated a failure |
This is quite unfortunate since adding -v doesn’t give any more information. Scouring the net, I’ve fount the following potential solutions: Retry multiple times as this might be a server timeout. I’ve reset the […]
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:

./adb reboot recovery |
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 […]
