CHAOS AMP

+ + + +

There are two different circuits in two cubes connected with a cable. Chaos are two oscillating circuits that modulate each other. The pitch can be manipulated by a photoresistor (LDR), and the pulse width by a potentiometer. The second potentiometer is used to set the voltage that supplies current to the oscillating circuit. This allows you to create versatile and very interesting sound. The other circuit is a simple amplifier with a speaker.

We built these cubes in the + TINKER TEC GIRLS + workshop at HSLU. For more information klick the link below.

AUDIO LASER

+ + + +

This experiment investigates how audio can be transmitted through the air. The signal is overlapped with the laser beam (analog circuit) and then picked up by a solar panel. The solar panel is connected to a simple amplifier that drives a loudspeaker. Klick the link below to watch the video on Instagram.

SOLAR CV

+ + + +

These solar cells produce a voltage of 0-5 volts. These are very suitable to be used as control voltage (CV) in the Modular Synthesizer. For example, a changing light source can influence a filter (VCF), the pitch of an oscillator (VCO) or the volume of an amplifier (VCA). When an autonomous patch is influenced by external sensors, it is also called an interactive generative system.

Another possibility is to feed the solar cell directly into an audio amplifier. Then e.g. the frequencies of LED’s can be made audible. Click the link below to watch an example.

ELECTROMAGNETIC FIELDS

+ + + +

Priezor from + LOM + is an open-source passive magnetic antenna for electromagnetic listening. It is very sensitive and capable of capturing faint atmospheric events in VLF radio bands. Compared to regular Elektrosluch, it is less directional and focused, and therefore more useful in recording ambient electromagnetic fields, where the overall “sound of the place” is desired.
