Here i am with all the components to build a servo based gimbal so i decided to try! Connected the MPU6050 to the servo via an arduino, kinda worked, but after a bit of googling noticed that this is quite a popular project:) And that the servo accuracy is not quite up to par. It is useful for camera rotation, but too janky for stabilization. I also found a lovely gimbal with brushless motors built in for a reasonable price so i'll probably use this part and get pleasure from implementing the brains - the controller of the gimbal. https://hobbyking.com/en_us/shock-absorbing-2-axis-brushless-gimbal-kit-for-action-cam.html or this http://www.banggood.com/Light-2-Axis-Brushless-Gimbal-With-BGC3_0-Plug-and-Play-Stabilizer-For-GoPro-SJ-Hawkeye-DJI-Cheerson-p-1104837.html?p=MY291110179142014129 I received my drone part from hobbyking (s500 based build) which was about $230 with everything beside the brains which i will build myself. I also want to add telemetry and video myself, with the help of the raspberrypi full hd camera which i hope to stream in realtime over wifi. Going to need a big antenna:)

A part of a vj set from k4, cant remember the date. Most prominent is the video recorded from "Pisma iz sedanjosti" (http://www.zavod-zank.si/korda/PiS/) and you can also see some live webcam (bad angle/light). Manipulated with naprava (http://www.naprava.net), the first effect is a plugin i made the same day, the grid colorizes depending on the movement of the video.

Things I'm Working On (TIWO!) is a series i started to motivate myself to post more and i'm sure you'll find something interesting in it, maybe even start a dialogue in the comments. In this video i present a project I'm working on with artist Jaka Železnikar, a doll which plays audio based on the gps location and compass direction of the doll. I connected an Anker power pack (chosen for its thermal and voltage protection;) to a speaker and a raspberrypi, which also has a gps/compass module integrated Jaka Železnikar: http://jaka.org/ and the project way back from 1997: http://www.jaka.org/1997/int/int.htm Gary Vaynerchuk https://www.youtube.com/user/GaryVaynerchuk GPS/Compass module: https://www.gearbest.com/multi-rotor-parts/pp_428512.html?lkid=11194827

Vertical flower watering spider basic prototype testing, strength of servos and general architecture. A basic thingiverse design (1603), scaled by 1.7x. Servos are now positionally calibrated, now i have to implement a keyframing system on the arduino to program the movements of a leg and all legs together.

A short video describing npStarter installation on an ordinary raspbian system running on a RaspberryPi. npStarter is a very basic init system for the raspberrypi, created to have full control of an otherwise fully functioning Raspbian Linux system. It replaces the systemd init system with its own setup routines and can also return control back to systemd for a full "normal" system. Requirements: - cmake (apt-get install cmake, I know it's just one file, cmake is a bit of an overkill:) - gcc Repository on GitHub: https://github.com/naprave/RaspberryPi For a quiet kernel boot your /boot/cmdline.txt file should look like: dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait quiet logo.nologo The " quiet logo.nologo" keywords are the magic here.

A quick overview of the synths functionality, currently it is set up as a rompler, playing 4 sample tracks for which you can tweak volume (0 - 400%) and speed. It is just a UI test, additions would be holding a button to enter fx editing mode, sample choosing, ... As i've currently got a 2in 2out soundcard in it (usb) i will probably change it into a granulator or something like that. http://www.naprave.net/en/blog/33/raspisynth/

One of the first experiments with the naprava platform, video was mapped as a texture on a 3d object. This video shows a huge object with a video texture being rotated. Developed around 2001, this was recorded around 2004. http://www.naprava.net

A part of my VJ set from the Vibe Department party with DJ Aphrodite. After intense tweaking this probably came about from a combination of Pete's ColorGlow and Wave effects... i love how it looks alive. I think there is also some refraction in it (and a hint of metaimage).

I was trying to setup video streaming from the raspberrypi (as it worked in the old days) and came up with some funky h264 encoding glitches! It kinda looks like a waterfall:) Not sure where exactly the problem is, i use raspivid to capture the encoded stream and pipe it into vlc for serving via http. Added some work in progress sound just to liven it up.

An additional video related to my "interaktivalij" project (https://www.youtube.com/watch?v=McDYHqKQejE) showing the soldering of the skinny wires of the GPS/compass module (https://www.gearbest.com/multi-rotor-parts/pp_428512.html?lkid=11194827). There is no physical pull on the wires so i didn't bother with the linemans splice, but it's still a nice tehnique: https://en.wikipedia.org/wiki/Western_Union_splice Music: Johhny, from my 200x compilation https://logista.bandcamp.com/album/200x

4 hydrophone recordings we made in the sea around Bergen, Norway on 21.11.2015. - First one is just outside the harbour (00:00), - the second is a boat passing by on the same spot (00:42), - third is in a secluded bay (01:19) and - fourth a point in the open (03:12). Visualized by me with OpenGL in realtime. Thanks to http://www.ultranoise.es/ for lending us the professional hydrophone (which we compared to our DIY ones:)

Video recorded realtime with naprava (http://www.naprava.net/). http://www.glamocanin.net/sound/bits-and-pieces/ Found a preview of an old unfinished song, added some freshly squeezed vj knob tweaking and decided to upload it. Music made sometime around 2005... Please listen in high quality (http://www.youtube.com/watch?v=XDlAnwkWGlY&fmt=18)

I made a "smoothie" to test my 4k video editing flow. Recorded with a MotoZ in 4k30fps, i used kdenlive v16.12 to edit the clips. The edits were minimal, just stacking and cutting off the edges. I took an afternoon to install gentoo linux on my Z800 workstation (24threads, 48gb ram) after i was disappointed with ubuntu. It worked, not ideally, with software compositing and using just about 6 cores for rendering h264. The GPU acceleration using the Movit library just didn't work, and increasing MLT threaded processing above 4 just cause terrible stutters. I tried VDPAU in vlc, too (nvidia quadro 4000), but the (4k) profile is not supported by VDPAU, so that could reflect poorly on kdenlive performance too, probably. It's been a while since Intels quicksync was supported by ffmpeg, but i don't think it has been integrated in this workflow. Should be a massive encoding win. After this i decided to focus on a video processing project, reading files (probably with ffmpeg-git) and processing directly on the GPU. I wonder how it will handle 4k:) I might even dabble in vulkan, but i noticed it is quite a huge api with great chance of not using it right:) The decoding, transferring to gpu texture and displaying should be a nice performance test for opengl. Also a quick comment on the video quality... it's a phone so it's best to use it for a well lit scene and optimal conditions to get the most out of it. I used the native app which has quite low bitrate, the 100Mbps bitrate is a lot nicer but it eats the storage like crazy:) Maybe for my ssd on a usb2sata adapter project:) I just remembered i could have added a background song (and some titles)... eh, in the next one:)

A VJ session i did for VibeDepartment for their party with DJ Aphrodite. VJjed with naprava (http://www.naprava.net/), started with a few prerecorded clips and realtime camera input of the actual party. The software features FreeFrame video effects and also allows for recording the video output and reusing the recordings in real time. The session was recorded in 2009, the song i made (with Impulse Tracker!) in 1999. Wow:) Put together for fun and to upload something (new:) to my channel.

Sit down, shut up:) It's not that obvious in the video, but she gave me the stink eye and started approaching, so i bravely decided to melt into my seat:) Recorded in the serengeti, Tanzania.

RaspiSynth development. It's a synth platform, this prototype is based on the basic Raspberry PI A model, using a USB sound card for better audio, connected via serial to an arduino pro mini (supplying it with 3v voltage so no logic converters needed;) which reads the analog values from the knobs and switches.

In my young days i played with data a lot and loved to trash the graphics framebuffer. This is one of the experiments i created. Kinda looks like a waterfall:) Sadly the controls are pretty poor, this is the slowed down version because it looks better. Recorded with dosbox.
