I felt compelled to write about music for a change, since it's mentioned in the blog header and all, so here's some criticism to begin with.
As a DJ I had the pleasure of closely following the development of rap music ever since the 80's, and IMO the "golden age" of the 90's was truly that. From 2000 onwards I've felt rap becoming too mainstream, too dumb and lacking meaningful messages...
LED wall control with Raspberry Pi, part 2
Wednesday, October 25, 2017 DJ Maraz
Problems, problems and more problems... This project is obviously turning into a fight, so I dug up some Spock quotes to aid me. Some interesting findings and mildly foul language are to be expected...

LED wall control with Raspberry Pi, part 1
Saturday, October 14, 2017 DJ Maraz
My IR camera project has been on hold for a while, because I've come up with other more interesting ideas, such as a LED wall. Initially I was inspired by the Aurora LED wall project, but I've realized that with the power of a Raspberry Pi and some Linux audio magic (PulseAudio and GStreamer) I could do much more...

Pre-enabling wifi and SSH on a Raspberry Pi SD card
Saturday, October 14, 2017 DJ Maraz
I've bought many Pi Zero W's, as they're just irresistibly cheap, so I have a lot of little Linuxes (or is the plural Linuces?) running around the house.
Unfortunately I keep forgetting how to pre-enable wifi and SSH on the SD card for a headless setup, and every time Google finds me old, incomplete tutorials, leaving me wondering why a Pi is not connecting, so it's best I finally write my own...
Infrared motion sensor camera with Raspberry Pi Zero W, part 2
Thursday, August 24, 2017 DJ Maraz
I decided to start with something simple like watching live video from the Pi camera on the local network. Raspbian comes with the raspivid utility, often used to simply record or pass camera picture to the HDMI output, but it's suitable for much more than that, especially with VLC, a multipurpose video toolkit...

Infrared motion sensor camera with Raspberry Pi Zero W, part 1
Wednesday, August 16, 2017 DJ Maraz
I've been planning to build a prototype battery-operated motion sensor camera using the latest addition to the Raspberry Pi family tree, the Zero W, which is quite a remarkable device for something smaller than my thumb. Even the wireless antenna seems quite revolutionary. With WiFi and Bluetooth built in, this tiny computer will be more than perfect for many IoT projects...

Context menu additions for sharing files in S3 buckets
Tuesday, August 08, 2017 DJ Maraz
Some time ago I wrote about mounting Amazon S3 buckets into your home directory, and I wanted to get automatic public URLs for sharing some of the files I stuff in my cloud buckets. I got it working quite effortlessly by writing a small script and adding a context menu item to my file manager...
Compiling ffmpeg with Raspberry Pi hardware acceleration
Thursday, August 03, 2017 DJ Maraz
AFAIK the regular Debian/Raspbian version of ffmpeg does not support Raspberry Pi's hardware H.264 acceleration, so I decided to roll my own. Compiling also avoided some bloaty dependencies that the package in the Debian (Jessie backports) repository has...

Using systemd to mount S3 buckets into your home directory
Wednesday, August 02, 2017 DJ Maraz
If you do web development or use cloud storage for backups, you may have heard of Amazon S3 which offers dirt-cheap storage for both private and public use. Data in S3 is split into "buckets", which can be configured individually and may contain folder structures.
Then there's S3FS (S3 File System) that allows accessing S3 just as easily as local files. The few tutorials I found used /etc/fstab...
Oh, so now I'm a blogger
Wednesday, August 02, 2017 DJ Maraz
Since I pretty much write for a living these days, I never thought I'd find enough energy and time to start blogging, especially after I ended my Twitter life as too time-consuming, but here we are.
I noticed that I've written a huge collection of notes that, with some refining, might be useful to others as well, and writing helps me remember new stuff that I keep learning. I guess those are valid...
