Technical principle of Fluctante is based on very simple mechanical effect. Performer can manually control a fluctuation frequency of different screw-bars, which are attached to the flat wooden surface. On top of screw-bars are nuts fixed with clothespins. Nuts are ticking in synchronization of fluctuation of screw-bars. Different length combined with different diameter creates both dissimilar frequency and tone. Instrument allowes different playing techniques based on fluctuation, percussion, scraping and screwing down the shims.

Source of sound in Aqumper is been created by an aquarium-pump, which creates pulsive airflow. If to lead this flow to the mouth through the hose, it turns an oral cavity into a sound-space. Changing its shape changes a tone of sound. As for the fact that airpump provides a constant airflow into the process, it gives a possibility of non-stop performance. Performer must not provide physical airflow and can easily breathe through the nose without interruption of sound.

The body of Buuzta consists in its main part a structure of plastic water pipes. Inside one end of pipe is a dynamic microphone. In another end is a subwoofer which emits pulsing soundwaves into pipe. Pulsation is been created by DIY oscillator. Low frequency pulsation modifies air-pressure inside the pipe. Tubular structure has gaps by different diameter. Closing and opening these gaps regulates air-pressure (tone of low frequency) inside. Another playing technique allowes to insert vocals into the pipe. In tubular enviroment it starts to boost vocals according to frequency and tone of pulsation.

The body of Springon is been combined of metal springs with different length and diameter which are played with self-made bows. Bows are made of wooden clothes-hanger and fishing-line tightened to it. Sound produced by metal springs is vibrative and tone depends on speed and intensity of impulse. Allows also to use percussive playing techniques.

Stringular is the only instrument which base on existing prototype. Basically it is one-string electric guitar. Only one string allowes performer to play with it without any earlier experience of guitar. Signal processed with electronic effects and experimental playing techniques allowes to shift its sound farther from „guitarish“ as we know it.
Ballos is a mechanical machine made of welded steel. Its heart is two empty gas balloons connected with hose. In the lower balloon is a 70 litres of water and water-pump. Cycle 1 launch pump which start to push water into the upper balloon. Mechanically balloons are connected with iron-wire. If the upper balloon become heavier than the lower-one, it will fall down and pull the lower-one up. In this position pump will be swhitch off, water starts to fall again to the lower balloon and both cycles starts to repeat. This kind of mechanical sequencer allows to mix its sounds with looper, add different mechanical and electrical links. Ballos has been used in exhibitions, performances, concerts in different roles for 7 years already.
