The Fish-Brain-Machine [Hall\/Dusseiller\/ Hackteria 2012] is a printed circuit board (PCB) that uses biofeedback [sweat response] to control two stroboscopic LEDs. Holding the circuit to the eyes induces psychedelic visual effects, colourful geometric fractal like forms for many users.\u00a0 The first Fish-Brain-Machine was created for a workshop that took place during the Enki exhibition at Kapelica Gallery, Slovenia 2012-13<\/a>. A second version of the PCB was produced for the Re-Mapping perception workshops at Radiona, Zagreb, 2018<\/a>. The circuit design is based on a diagram of a Black Ghost Knifefish, a kind of electrogenic fish around which the original Enki project was based.<\/p>\n

WORKSHOP:
<\/strong>During this workshop participants assemble the circuit and experiment with the effects, such as different coloured LEDs. Participants can also construct their own Ganzfeld goggles, to be used in conjunction with the PCB, which enhances the effects.\u00a0<\/p>\n

Particpant experience transcript 06\/2019<\/p>\n

\u201cIm getting what look like ripples, mostly white and blue, oh shit, there\u2019s like halos of different colours on it, its really like video feedback, hexagons flashing on and off with interference looking, \u2026sort of a grid, I\u2019m seeing green and yellow now, white and blues, whoooo, ok\u2026Yeah I don\u2019t want to stop.\u201d<\/p>\n
