PIFcamp 2017 – Day 3

Despite a long previous night a small group woke up early and start the day with yoga. As Gea was absent it was led by our man with many talents – Andrew Quitmeyer. He is one of the central figures of this year’s PIFcamp and is the one, who might also be the most recognisable one. Some of you may know his as an author of the television show Hacking the Wild. Well, for a job well done he was awarded with a wasp sting at the end of the session.

After breakfast the majority of participants went on a hike with our wild man  Dario Cortese, who led us up the hill to a nearby deserted village Lemovje.

We made our base their for a short time. While some left to catch a glimpse of a spring, which was located approximately a ten minute hike away, the others joined the workshop led by Hannah Perner-Wilson and Mika Satomi from KOBAKANT. We gathered various morphologically interesting plants, which might be use as accessories to the interactive garments they are planning to build.

In the meantime we were having fun with co-creating Hannah’s “green” T-shirt. That meant we covered her in stinging nettles. As they have hairs they are highly suitable for instant textile design.

While we were walking, we naturally gathered some more of the delicious wild plants growing in the vicinity. We also got to find out about some new ones. What we gathered later became an ingredient in our meals, but we also made a really good tea. The hike was crowned with a mandatory daily swim and many refreshing jumps into Soča.

The wind was suitable enough for Cindy Regalado and Luka Frelih to try out if the day was good for flying kites. The kite did take of, but not high enough to take appropriate pictures. Cindy therefore decided to explain remaining steps in the process of this specific way of map making. We got to know the program with which one can process the images and “stitch” it together. They also tried to fly the kite again in the afternoon, but this time, although the altitude was suitable, something went wrong with the camera.

After lunch we partook in a short workshop, in which we learned a lot about the uses of whey and making yogurt. We added some black currants and several local herbs to milk in order to check if they contain suitable bacteria for yogurt making. We will find out if they do tomorrow. Vaclav Pelovšek lead a quick course about the of modular synthesis. Some joined Andrew in making silicon casts of the plants we gathered on the hike. In the coming days we will be using the moulds to make organic shapes from chocolate or epoxy resin.

Lavoslava Benčić (from ČIPke), who has been working on her electronic gloves for the third year on PIFcamp now, decided to try and make an orthopaedic insole from kombucha. But, as it turned out kombucha doesn’t have enough of a “spring” effect when dry. Staš Vrenko and his group successfully finished the etching of eight circuit boards in the bathroom, which they turned into an improvised darkroom.

The electronic accordion project is almost in its closing phase. Vincent and Mojca focused on determining if the electronics programming was done correctly, meaning, if specific tones answer to the assigned keys. Light box by Špela Škulj, made for screen printing, will be ready by Friday and we will get to try it out by making PIF T-shirts. By the evening we also got a first taste of the candy which will coat the electronic bonbons. The camp seemed like a well organised anthill at some point. Everybody was busy doing something. Gregor’s analog sequencer is also finally getting shape.

This night turned into a cacophonic symphony of sounds. PIFmusicians made them with drums, a bagpipe, flutes and synths, but this wild jamming was soon stopped by a temporary power shortage. So, most of us went straight into our beds, as the next day will be full of new adventures – some planned to go on another hike to Lake Krn at the break of dawn.

PIFcamp 2017 – Day 2

On the second day a good dozen of us started our day with yoga. Gea, our flexible yoga instructor, dedicated a good portion of our session to meditation and relaxation, while the rest was spent in various poses. We definitely got a good morning stretch.

Right after breakfast Staš Vrenko took care of the mandatory morning dose of knowledge-sharing. He led an introduction to circuit schematic drawing and  shed some much needed light on the principles of etching. Some circuits will be drawn and etched tomorrow.

The electronic accordion by Vincent Groenhuis and Mojca Miklavec is getting along quite nicely, but Cindy and her group didn’t manage to fly their kites. There was no suitable wind… Their spirits are nonetheless high, and they will try again in the forthcoming days.

The group that joined Rosen Ivanov in making a carbonated mate drink added wild yeast, ginger bug, whey, water kefir and kombucha to several glasses containing mate tea with sugar that was prepared yesterday. They tried out different ratios in order to find the combination with the right amount of carbon dioxide, which would also taste good.

After lunch some of us chose to go on a short stroll along the Soča river with our wild man Dario Cortese. We searched the nearby meadows to rob them of their aromatics and other edible plants. The summer savory,  wild carrots, wild garlic and nettles we gathered ended up in salads that accompanied one of the delicious meals prepared by our lovely chefs Tereza, Maruša and Tea. They are truly spoiling us.

We were joined by Hannah and Mika from KOBAKANT today. They shared the timeline of their project in which they will combine wearables with local plant life and sounds.

In the afternoon quite a few PIFparticipants made their own simple echo sound effect under the watchful eye of Peter Edwards. As there are so many musicians on PIFcamp this year, we can expect to witness and take part in many jam-sessions and performances.

When something turns out to be an excellent idea, it is bound to become standard practice, so like the first evening we went into the woods to gather wood and make a bonfire before it turned too dark. After another delectable dinner we were graced by the visit of the local chaplain. And after that the happening transformed into a super birthday bash – chocolate cake and all. The atmosphere grew more electrifying by the minute as sounds from modular synths permeated the evening air. John Dinger, who celebrated alongside Lio, had the honour to set the vibe to the pleasure of everybody present. It was not hard for Peter Edwards and Václav Peloušek to pick it up and make this night a thing to remember.

The PIFcrowd was enthralled also by Bernhard Rasinger, who use the nearby treetops as a screen for his laser wizardry.

Time flew by as August shooting stars this sweet night of music, dancing and passionate debates, and the sky was turning back to blue when the last man standing went off to his well-deserved rest.

PIFcamp 2017 – Day 1

After the initial introductions and some time to get to know our surroundings, we lent an ear to the first project presentations and started to plan the week that approximately 50 avid lovers of technology, art and science from all across the globe will spend in the beautiful Soča Valley for the third year in a row.

Peter Edwards, an American currently living in Czech Republic, is among us once again! He works with Václav Peloušek and Tomáš Niesner, who are part of BASTL Instruments, a company and a collective based in Brno. Some of the PIFparticipants familiarized themselves with their modular synths before their first PIFdinner.

Another guest of this year’s camp is Andrew Quitmeyer, who started the day by demonstrating how to use a drone and in the evening also explained all about laser cutting on various surfaces such as plant leaves and wood.

Some also got a chance to delve into the world of oscilloscopes. The man who brought them to Soča is Bernhard Rasinger, who wants to explore ways to integrate modular synth circuits, oscilloscopes and lasers.

Our very own agricultural dissident Dario Cortese announced several walks into the wild, where there will be heaps of opportunity to gather medicinal and edible wild plants growing in nearby pastures and woods.

A novelty of the camp this year is a focus on the development of workshop programmes for youngsters, which will be led by Cindy Regalado and Kristijan Tkalec, also a part of the Rampa Lab and BioTehna team, co-producers of the 3rd PIFcamp. Cindy explained all about her PIFnode, which involves flying kites, equipped with a camera, over the PIFvenue and its surroundings. With the kites she plans to take aerial shots of the area, and combine them in order to generate its map.

Naturally we are excited about all PIFprojects. Yair Reshef and Zohar Messec-Fara will create electronic lollipops, for example, and the Dutch-Slovenian connection – Vincent Groenhuis and Mojca Miklavec – are working on a modular accordion. We are also waiting impatiently for the arrival of Hannah Perner-Wilson and Mika Satomi from the KOBAKANT collective, as they will design and execute a new and “all-natural” wearable technology.

The nutritional enthusiast Rosen Ivanov completed some of the initial phases in his quest to find ways to use carbon dioxide formed in the course of fermentation in the creation of fizzy drinks. He plans to use wild yeast, whey, water kefir and kombucha. We might get to try out his creations from yerba mate by the end of the week.

A proper anthropological study of the knowledge-sharing processes at PIFcamp by Ahac Meden is apparently forthcoming. No wonder, since PIFcamp encourages all forms and the creative use of modern technologies while emphasising active project co-creation and the free distribution of knowledge, ideas and experiences.

Looking forward to the coming adventures!

Bio-fermented Mate Drinks

“Materva” has become a symbol of Cuban diaspora and nostalgia of pre-Castro Cuba, “Club Mate” is the preferred and signature drink of most post-Fordist alternative engineering cultures (a.k.a hackers), and “Nativa” became a known Coca-Cola market flop in Argentina. What unites those three drinks is the idea of carbonating the famous mate tea into energizing soda pops, or gasiosas de mate.

This project by Rosen Ivanov comes from his passion for ilex paraguariensis, or yerba mate, and its fascinating social history and traditional uses. After working on a soda-pop from yerba mate in the local Barcelona biohackerspace, Rosen decided to try various methods of natural carbonation for brewing traditional tea fizzy drinks.

On the first days of the camp, he invites you to experiment with him on different ways of using fermentation’s CO2 for making sodas-pops. He’s intending to try the following cultures, but any other methods we can work with are highly appreciated: ginger bug, whey, water kefir and kombucha.

Environment reading sensors

With the help from Kristijan Tkalec (BioTehna) participants will submerge into a collection of sensors and use Arduino microcontrollers to assemble new devices, which will help them to sense the surroundings more efficiently. The node is open to all aspiring explorers who want to familiarize themselves with the basics of programming, Arduino use and sensors. The goal will be to make as diverse and interesting little exploration devices as possible. They will be used for tracking temperature, humidity, the UV safety according to the UV index, the amount of carbon dioxide and so forth. The most interesting specimens will be recreated in the workshop for children, which will take place on PIFcamp’s Open Saturday.

Prepared circuits

Project Prepared circuits by Staš Vrenko is based on the creative and individualized exploration of the basic principles of sound circuit integration and connectivity. Taking a hands-on approach the participants will therefore be able to familiarize themselves with the concepts of non-linear feedback, logical circuits, circuit bending and physical sound processing.

In the first part of the project participants will assemble the electroacoustic instrument and tool for the physical manipulation of sound Soda v0.5b.

Soda v0.5 is a semi-modular instrument with several inputs and outputs, which enable intervention into the circuit’s signal path. This signal starts with a jack input, which can be used for plugging a contact microphone, a synth, a guitar magnet and so forth. We can then amplify the signal, filter it and much more. What follows is a voltage controlled oscillator (VCO), which is turned into a live ramp waveform according to the range of the signal’s amplitude. In the circuit’s output phase the signal physically manifests itself in the form of a line output and an internal power amplifier which powers the speaker.

In the second part of the project participants will add various external circuits and physical contraptions for sound manipulation to the device. They will be chosen on the basis of personal musical/sound preferences.

The expansion process of the formal and consequentially functional features of the basic instrument will therefore serve as a possibility of the further individualization of instruments and sound generators.

Piezo invasion of integrated circuits by Anton Prykhodko

Ever been wondering how to use a contact mic with your DIY synthesizer? Say, as a trigger for the envelope generator or as an impulse to the resonant low-pass filter? If you think of contact microphones in modular fashion, this is just a pinch of what they are capable of.

Piezo electricity is there to be a transducer, the medium between electronic and acoustic domain. Meaning the piezo disc can pick up vibes as well as vibrate itself like a regular speaker. When both of these functions get together – with one mic listening to its own electrical signal from another mic – you get feedback which is nothing but an oscillator.

The contact mic also allows building processing units from solid materials. Turn slinky into a spring reverb effect, make a crumpled plastic case into a band-pass filter, boost the lows with a balloon equalizer or let piezo itself, considering its high voltage output, drive the op-amp overdrive unit.

Anton Prykhodko will spawn a plethora of contact microphones to explore interaction between electronic and piezoelectric circuits. To get all those squeaks and creaks he will plug sound modules into a mixer matrix with multiple outputs and feedback paths.
