As part of my exhibition at Kapellica Gallery in Ljubljana, I developed a related perceptual illusions and brain hacks workshop with Marc Dusseiller [Hackteria], as part of the gallery’s Biotech program. We came up with the idea to make a special issue circuit for the workshop and we set to work designing a circuit the encapsulated the enki project in miniature.
After a couple late nights we came up with this super cool PCB design. Marc worked hard to create a fully functional efficient design, which was also aesthetically pleasing. The outline f the fish is also the ground in the circuit. This has to be the most ultra minimal brain machine available to build. We spent further late nights acid etching the circuits for the workshop in Marc’s home lab.
It uses ‘biofeedback’ to control the pulse frequency of the lights. No Ardunio. Your fingertips press on the fingerprint, acting like a simple resistance meter, sensing the sweat levels to control strobe frequency [specifically 10-30htz to create hallucinations] of two ultra bright LEDs to create the optical stimulation. The capacitor and resistor set the standby slow pulse and the range within the level necessary to cause visual hallucination. The design incorporated measurement graduations for eye spacing so you can personalise LED placement to fit your eyes. It’s possible to use extra LEDs and several colours. After soldering the 6 components its possible to layback and experience your own personal electronic psychedelic experience.

During my visit to Ljubljana in I was introduced to the ‘Workshopology’ concept and network. The idea is to bring together likeminded ‘Workshopologist’ to discuss methods and best practice in this area. More specifically the participants are dealing with similar subject matter. Open source collaborative approaches to teaching and learning in DIY electronics, science and biotech. Taking part are Artist, engineers bio-hackers and scientist and various other creative ‘workshopologists’. We discussed the workshop as a tool for delivering and sharing knowledge outside of traditional educational frameworks, how types of workshop can be categorised and analyised.
Outside of my own personal workshop practice it was interesting to think about iLog workshop as a take on the electronics kit where limitations are provided as a mode to instigating creativity, the log casing is the blank canvas for the interface as well as being the limiting framework. Also how the resulting community exists in some remote collection of created objects artworks sitting in wait for the next performance on some mantelpiece. In other contexts communities depend on an anchor points an individual, or space within which these things can happen.

Rubber/wooden hand experiment.
I have been interested in the phenomenon of the rubber hand experiment and recent studies relating to experimental induction of out of body experiences. This interest is partly for personal reasons relating to my experience of sleep paralysis and lucid dreams, but also because I have been doing some workshops on visual and perceptual illusions, and 3D stereoscopic image making. I thought t would be a good idea to start with the rubber hand experiment and also try the experiments in body swap by Henrik Ehrsson and Olaf Blanke. http://www.eurekalert.org/pub_releases/2007-08/ucl-foe081407.php
I invited some experts to the studio who I thought might be interested in trying these experiments out and perhaps developing them. They brought presentations and some kit to do the rubber-hand experiment, most importantly a realistic rubber-hand. I borrowed some HMDs so along with a DV camera we had everything we needed to experimentally induct an out of body experience.
I was amazed at how well the rubber hand illusion worked. In this experiment the fingers of the rubber hand are stroked synchronously with the real hand [hidden from view]. You see the rubber hand in place of your own. As the illusion kicked in I began to feel strong connection with the fake rubber-hand. I felt the unnerving sensation that the rubber hand was infact, my own hand, and always had been. It felt that at any moment I could start to move the hand. It started to feel heavy, and this made my arm start to ache.
To be honest before i tried this I was slightly skeptical of this experiment, I was not convinced that the effect could be strong, total, or convincing’. For me there were several stages; a weirdness at the beginning, where I though nothing more was going to happen; this then increases as your real hand starts to feel very odd. Then there is a drifting and a odd numbness as you begin to connect with the rubber-hand, this connection then becomes strong, and even remains if visual contact is broken with the hand. I had an idea to try a wooden hand, and this worked surprisingly well. It made you feel as if your hand was shinny hard and smooth. This left me wanting to push this experiment further; What happened if you swapped the hand for a modified hand during the experiment, used less fingers or increasingly abstracted the hand progressively? Use a hand with just 3 fingers or a beast hand with hair and claws?
HMDs for the body swap experiment; even this early model seemed to prove quite effective for the experiment
Attempting the hand-shake illusion which work quite well even working cross gender! This feels like you have swapped hands with the other person or that you have lost control of your own hand. We also tried the set up as illustrated above. Like the rubber-hand it seemed there were progressive stages where so called ‘ownership’ shifts to the virtual body. In our experiment we really only entered a mild sensation of ‘weirdness’ in a similar way to the rubber-hand experiment. From here we could not quite get to a total shift of body location in a strong sence. Given my skepticism about the rubber-hand experiment, I am now convinced that the Body swap illusion could create a very strong sensation of being removed from ones own or OBE. Next time to do this experiment effectively, we need more space and time to set up and less visual distractions in the space.

12 pentagonal faces, 12 speakers
I have had the opportunity in the past to work with a 10.2 surround sound system; although the sound was fantastic, I found this problematic. People will talk endlessly about emulating ‘realistic’ sound, but generally there is only a small sonic sweet spot, [in the centre of the room] so you are not totally immersed in the sound unless you occupy that spot. Personally I find stereo is equally problematic. After getting quite excited about working with loads of channels I went back to working in mono so I could concentrate on the sound output and be more confident about knowing what it was sounding like on the outside. I also wanted to work with something that had its own inherent sound quality. With the dodecahedral speaker, the idea is that the sound you hear comes from one spot. The dodecahedron emulates a spherical sound source or point, which propagates sound around the space to fill it.

This is my ultrasonic sensor, during the first days of the radar residency i have been doing some experiments with this to find out how it works – essentially i am hoping to use it as a way of creating a human echo-locating device. essentially it seems that this measures the distance between an ultra-sound pulse and its echo. we connected this up to a oscilloscope to see how obstacles looked in terms of the sound reflection…
Apparently, Shrews are the only terrestrial mammals known to echo-locate [and the Tenrecs of Madagascar]. The shrews emit series of ultrasonic squeaks.
“Human echolocation is the ability of humans to sense objects in their environment by hearing echoes from those objects. This ability is used by some blind people to navigate within their environment. They actively create sounds, such as by tapping their canes or by making clicking noises with their mouths. Human echolocation is similar in principle to active sonar and to the animal echolocation employed by some animals, including bats and dolphins….Some blind people have described the phenomenon not as a learned method of navigation, but as an inherent and intuitive extra sense. For example, a blind person could walk past a line of trees and feel a “pressure” at their side as they passed each tree. The cause of this would be the echo of the sound of their footsteps; however, they may not consciously be aware of this mechanism, only that the phenomenon exists and can often be relied upon to detect obstacles.”
Pauls experiment investigates how dolphins detect sound using the jaw bone – this box has metal rods inside in a line [aproximatly representing the allignment of teeth in a jawbone] – so as the sound wave travels through the channel, the rods act as a filtering device – or at least that is the hypothesis [very briefly]. Apparently dolphins use their jawbone as a way of honing in on the direction of certain sounds.

Here are some of the latest images from the Enki project…
The main view of the experiment chamber. The Enki installation at Cornerhouse is now up and running. There are experiments by appointment every 15mins, and all the data is being collected.
It has taken me ages to make these comms units, they contain16 interconnecting cables within a noise reducing or shielded structure.
The Table has two monitors one from the fish room and one from the human room. You can speak to the person in the experiment via a mic.
Inside the sound proofed room for the human there is a chair and the sensor interface.
There is a window into the fish room on the side of the chamber
The room containing the fish is electrically shielded.

For a while i have been looking at Michael Persinger God helmet experiment, I think the discussion around this experiment was really interesting, and for me has been an opportunity to investigate the realm of psychology further. I got in touch with him to ask some questions about the technology and the experimental process. I decided to make a modified version of the god helmet to work with my Enki interface. here is a view Inside the neuro-stimulation device there are 4 coils which oscillate with magnetic frequencies, i have been using MAX MSP to drive these using electrical pulses. The magnetic coils are fitted to an elastic band which fits over the head, to the back of the head is a junction box, and the two coil arrays sit at the side of the head near the temporal lobes.

This was amazing at the opening of Spectropia- the drinks were covered in foil [apparently to shield them from EM fields [many themes in the conference were to do with the potentially damaging effects of EM emissions] and these was a chef making toffee apples live! they looked so amazing who could resist. The funny thing was that as soon as you bite in to them you teeth get fused together with toffee making it impossible to speak for several minuets!

In 2007 I participated in ENTER 3, http://festival-enter.cz/index.php
organised in by CIANT, I never had a chance to blog it. I had two works here, one of which was a performance showing the BZ reaction, the other was the ENKI documentation at the french institute. The Performance was in a 15th century cellar space, beautiful arched ceilings. The problem was it was so cold the chemical reaction did not start. I had to block all the window spaces with cardboard, to try and keep at least some heat in.
The vampire quid was of inspiration to Louis Beck – I was lucky to see a show of his posters and publications last year at the Goethe institute…Having seen the vampire squid recently on utube it reminded me of the Louis Bec show I saw during the festival…
