I have experimented with the Casio SA-20, by reducing the power-supply voltage from 7.5V down to 4.1V. at this voltage the instrument starts to sound strange and become very glitcy. The keyboard makes random noises in a way that seems like internal datalines are being filled with errors resulting in wrong serial messages, hence the …

Output Festival 5
I performed as VJ (Video Jockey) at Output Festival 5, held at Rå-Hal – Godsbanen, Aarhus. 22-23 of October 2021. I also exhibited a couple of artworks as well. Below is a full song by the band ‘Joeham’ at the festival. Visuals in the background are live performed by me.
Flickering Container
This artwork is a old wooden, golden frame. I replaced the glass with chicken fence and plastic. The plastic has been heated so it is slightly melted. Underneath the plastic is mounted leaves on boards with LEDs underneath. The LEDs under the leaves glows in different colours while LEDs underneath the mounted leaves flicker on …
ATtiny85 envelope module
Decay-envelope-module based on a single ATTiny85 microcontroller with multiple outputs based on triggering. Features: Gate signal for when the envelope is active Rising edge trigger output Decay/release length Digital envelope output SOURCECODE
Clock multiplier
This is a clock multiplier made for musical purpose, such as synthesizer/modular-systems or other things that would send out or receive 5v pulses. The current code is written for a ATTiny85, but should work fine on any Arduino etc. The program measures the time between each pulse input, and outputs a repeating pulse with an …
TimeStep Sequencer
This is a sequencer made for controlling modular systems. It has 8 knobs controlling the time/length of each step and 8 knobs controlling the CV output for each step, generating interesting rhythmic patterns. The sequencer has a random mode, start/stop, two time-multipliers and a slide switch. The sequencer is based on a teensy 2.0 source …
Noise Toolbox
This is a modular synthesizer build with focus on noise music or non-musical purpose. Using different effects, filters distortion etc. weird noise can be generated through feedback loops or external input. Overview The unit contains the following modules: 3 delay modules 3 distortion/wavefolds 2 tone controls 1 dual equalizer 1 3×3 matrix mixer 1 oscilator/LFO …
4 Voice drone-machine
4 Voice drone-machine This is a drone machine consisting of four identical oscillators. Each oscillator can be tuned by two potentiometer; course and fine. A patch-bay on the instrument are used to cross modulate the different oscillators, through frequency divisions. The machine also have a tone-control and volume control for controlling the output. Schematics The …
Video Synthesizer
Video Synthesizer This is a video synthsizer cable of synthesizing a VGA signal. The instrument/tool is based on a VGA-test module, with its VGA-output broken into multiple signals. The signals can be patched through different other modules such as a clock divider etc. The insturment can be used for VJ’ing og just pure fun. The …
Conductive Touch synthesizer
Conductive Touch synthesizer This is a polyphonic synthesizer made schmitt-trigger oscillators. Signals from each Individual oscillator is transfered through finger/flesh and into the mix. This also make it super noisy. The circuit for this projects is very simple. 12 schmitt-trigger oscillators are all connected to different copper-pads, which line up with copper-pads going to the …
