It’s an interactive box with spindles and a hand crank. There are two guitar wires strung across the front. Inspired by the first ever beat box made in 1856 by a Swiss gentleman near the Swiss/German border. That last part is definitely not true.

This was originally some portable-radio type toy with 4 buttons, with drum sounds. I changed the button contacts to metal sponges and car antennas, all tied together with wonderfuls crocodiles clips. Playing along with it is a 555 oscillator, executed by Isis Abigail, using herself and a Plectranthus Australis plant as variable resistor.

“Branch keyboard: The concept of keyboard from wooden sticks was mentioned by a pioneer of hand made instruments from Czech republic Standa Filip as his first electronic keyboard instrument built in 1976. As many others, this instrument was lost or Standa gave it to somebody. Anyway, he doesn’t remember now who was it. Standuino team remade this thought and created functional imaginative replica of such keyboard instrument. The use of rough wood is characteristic for the poetics of the Standa’s musical instruments.”

Floating Record Player. 7 vinyl records are suspended in the air by electromagnets. A tonearm is mounted with an optical sensor which picks up the light patterns from the surface of the record. There is no needle touching the record. The optical sensor acts as a virtual stylus hovering above the grooves. Sounds are processed in a sound-generating software program and amplified through speakers.

The DF-I consists of 4 stepper motors, 4 piezopick-ups, and one controller. The name DF-I can be traced back to the abbreviation “DeFi”, which stands for defibrillator. Since a defibrillator can be used for resuscitation attempts, the DF-I can also be used for musical resuscitation attempts on almost every object. The stepper motors generate the sound. The surface of the object transmits the sounds to the pick-up.

I’ve taken multiple strands of dental floss and made guitar strings from them. For the thicker gauges of string I used more strands of floss. After developing the technique for making these dental floss guitar strings I contacted Ewan Dobson, a very talented guitarist from Toronto.
