Welcome to the lab! Here we tinker, solder, experiment with electronics and make things vibrate. It’s a physical and mental space where we develop new ideas for prototypes and build awesome sounding instruments.

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.

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.

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.

ELECTROMAGNETO PHONE
Priezor from + LOM + is an open-source passive antenna to make electromagnetic fields audible. It is very sensitive and detects low level events in the atmosphere. All electronic devices in the home or for outdoors, e.g. mobile phones, flat screens, sockets, etc. emit electromagnetic waves and sound very different. Which source sounds the most exciting to you? How can we explain the different volumes? And how do you perceive these devices now that you can hear them?
