This is another build. A laser set of three modules (power supply, driver module and galvo + lasers module) from China – put into enclosure. Added audio preamp for audio XY laser deflection control from computer – and some additional midi options (switching on/ off one or more of the three RGB laser modules).
On the top left: schematic swith stereo audio op-amp preamps for XY deflection galvo control

It took about 25 years that a special type of loudspeaker – vibration speaker – came to widespread use.
In 2022 I was to give technical help to realize a set of light transmitting and receiving devices. On the receiver side a vibration speaker was to be used (namely: Dura Mobi Speaker Hummingbird bone conduction speaker). In further research I came across a larger 20W version of a vibration speaker.
With vibration speaker the sound is created by transmitting vibrations... more
Sistem je bil izdelan po naročilu: za šest diaprojektorjev (po dva kažeta na en zaslon = trije zasloni) in računalniško voden sekvencer za proženje diapozitivov.

This is some help on the level of electronics and arduino programming to bring NAME:’s idea of “policijska ura” (-> curfew) to materialization.
LED lights
Name: had a large number of LED lights taken from a Lidl’s dump. Each of these led strips originally used a separate constant current driver (42V / 300mA), which was useless for this project. In the end we used a simple current limiting resistor per led strip -> 39ohms / 0.5W and one PSU block with 43Vdc (t... more
TurboFlutes are midi interfaces / breathing – not blowing instruments. Two prototypes were built in 2020, additional work was done in the next years – along with the preparation of printed-circuit-boards, etc. – and concerts…
During the first steps of elaboration it was clear that normal tone intervals as for the flute will be used. This made up a 12-tone scale with seven buttons on top. On the bottom left-hand side one octave up transposition button was replaced by two &... more

AI_SI Piano stands for a midi trigger device based on a touchpad system found in any laptop computer – brought to a form of an oversimplified instrument that acts as piano. It was a fast idea from a recent real piece of a dream of mine – in dream i would just bang with my finger on a touchpad – and this sounded as a “veritable” piano…
So: again one of the projects that is not linked directly to some envisioned artistic output. But as an instrument it c... more

Wordpress plugin – BS Sound Cumulus Plugin
Visual sound jukebox mixer based on once prolific tagcloud plugins (wp-cumulus, wp-cirrus, …). Now this is turned into random html5 player of mp3 files that the plugin finds on the site.
Some statistics is used to evenly play excerpts of audio files. Clicking on the cloud item overrides this mode and plays the whole file. You can also specify a su... more
Travel guitar is usually a short version of regular length guitar. In this case the strings are folded at the bottom and machine head is at the back. It is an electric guitar with a relatively wide fretboard (for my thick fingers) – basically a copy of the acoustic guitar that i have.
The final motive is simplicity and precision. Again the Cirkulacija 2 space proved invaluable for this project! CNC2 router was used throughout.
The idea came after a plan to have a performance of a p... more
It happens that experimental approaches have victims. These are amplifiers and especially loudspeakers. Two amplifiers and a couple of loudspeakers of Cirkulacija 2 are now dead. What was needed is an effective audio compressor/ limiter. This is it. After recent changes seems to work well.
The nature of limiter is that it instantly changes the amplification factor – the moment the input peak signal surpasses a certain voltage level – all the sound is than pushed down at the output. T... more

In 2017 I decided to finish building two pieces of “classic” theremin by using the two printed circuit boars that i etched five years ago. The circuit is basically the “etherwave” theremin by Robert Moog. The prototype was built and tried successfully at that time – but then the time somehow evaporated. So this now is the psycho-disciplinary action: finishing what was started – and: something to do in-between.
I was able to do the instrument building in the wo... more
The two loudspeakers were built using sewer pipes. This gave the name: Plečniks (suggested by Vlado Repnik, when used in his theatrical performance in 2018 -> HONEY, CINNAMON, RAISINS AND TIME robot fugue for live art / balletquintet w/m Stefan Doepner, Marieke Sophie Werner, Borut Savski and Vlado R. Gotvan). Jože Plečnik was an architect who built most of the representative buildings (and bridges) in Ljubljana – his very post-modern idea was to use large pre-built sewer pipes as pillars ... more

After some research of how to build a real subwoofer system for the projects at Cirkulacija 2, the two main principles emerged:
– transmission line (a quarter wavelength) principle
– and a bass-reflex principle
In both cases there is an additional tuned situation at the lower end of woofer frequency spectrum, that allows to get about an octave lower response – then the loudspeaker’s enclosure resonance allows.
The usual approach to push the loudspeaker l... more
The bible of acoustics. The pdf is of a book which i read a lot at the Technical library of the University of Ljubljana in the early 1980s. First published in May 1957 – based on an earlier work entitled Elements of Acoustical Engineering, by Harry F. Olson, copyright 1940, 1947 by D. Van Nostrand Company, Inc.

For the Cirkulacija 2 project of Cultural Interfaces in 2015 i devised a spheric type of wireless interface called IBALL (the big ones) and iballs (the little ones). It is arduino based wireless midi controller of XZY position.
Originally it was used to control the turning of the XY loudspeakers which Stefan Doepner made for Cirkulacija 2 events. At the same time it was a controller to play directly on the midi input to various software.
It can be used as a transmitter/ receiver of midi t... more

DB50XG Yamaha daughter board bought years ago was finally used to make a stand-alone midi synthesizer – as it was envisioned. Arduino platform had to come my way – to be able to do all the little programming to be able to set the the instruments manually with rotary encoder. It is now used extensivelly.
The board can play back very high quality samples from the extended midi (XG) set of instrument sounds. While for artistic approach I prefer the co-called “de-naturized” s... more
In May 2013 there was a couple of events with Borut Savski in Switzerland: a concert performance at Klubi experimental music club in Zürich, a week spent at Anyma hackers’ week in Fribourg and a workshop on building Cirkulino midi sequencer at SGMK Zürich. Thanks to Dusjagr!
The Anyma week was interesting as a meeting place of various diy electronics related people from all over Switzerland. A bit of insight into what they do. The gnusbuino direct midi usb series is something to focus o... more
