autonomous robots for okno’s OpenGreen

An experimental and playful hands-on workshop by Ralf Schreiber and Christian Faubel.

…it is a lot of fun to build your own robotic creature. As soon as the circuit starts working the robots begin to sing and jerk – there is always a great Hello.
It’s a magic moment and the constructor’s pride is often mixed with a little fear, that continuing soldering could possibly damage the just created little robot.
Time and again it is amazing to see, that such a wimpy, handcrafted creature can arouse empathy, can even activate a certain care in the builder…. (rs)

The most simple way to create and build “life like” machines or robots is by the use of analogue oscillator circuits. Oscillations can be feed-backed and thus simple interactions will happen and simple neuronal networks behavior can be simulated.
In this workshop we will build different kinds of machines. In combination with tiny motors and loudspeakers (piezos) they will generate smallest movements and soft sounds. All these machines are based on extreme low energetic circuits designs and get powered by the electric energy from tiny solar-panels or wimpy diy batteries.
All the finished machines can be exposed / set free in the garden. Furthermore some “creatures” can be connected or integrated to botanical or fungal organism (the plants resistance/capacity will get an integral part of the oscillating circuits).
For the design and look we will recycle & reuse wimpy stuff and elements direct from the garden: leaves, thin twigs, wax from the bee hives…


honeybatteries and a soundmodule – materials of the OpenGreens

Candlelight robots, a project developed by Christian Faubel.
The project consists of tiny mobile robots based on the suneater-circuit. They can be driven with just the flame of a candlelight. The light of the candle is transformed into electric energy that is stored in a capacitor and then released to a motor, producing movement. Christian will experiment with the workshop participants to make candles that move autonomously with only the energy from the flame. The circuit and motor will be casted in beeswax, with just the motor shaft and and the solar panel sticking out.

Enhanced Beehives – Electronic Creatures*

An experimental and playful hands-on workshop (BEAM related) by Ralf Schreiber.

Schreiber is building solar-powered electronic insects that sing, chirp, swing and crawl. These little creatures get their energy from the sun and will probably outlive most of the fine electronic devices surrounding us today.
During the past few years Ralf has given numerous workshops around the world, teaching people to build their own robots from cheap components.
This knowledge does not only give people the possibility to build funny little toys, it also gives people more control and understanding of their increasingly technological surroundings.

splinterfields: on electromagnetism, psychogeophysics and urban beekeeping

Workshop on electromagnetic arts. Interference-free Foraging Mobility in Brussels.


Results of December 12th walk (5 walkers, 5 devices) in the garden of okno (Again wide band high frequency intensity).
http://www.psychogeophysics.org

Electromagnetic fields can have adverse effects on living organisms – honeybees are especially sensitive.
Although urban environments provide beneficial habitats for bee colonies, the electromagnetic field concentrations can disturb the bees’ orientation and communication capabilities. To assist city bees with this issue, participants can work on an interference free foraging map.

DIY solar cooker workshop

the fun panel solar cooker cut the aluminium paper testing it out! setting up the cooker on okno's rooftop domes and cookers

calculation and cutting finished! second try solar cooking rice and vegetables so-on rooftop solar cooking

Thursday 24 july 10 women (and 3 man) gatered at okno to build solar cookers. It was a sunny day, luckily.
In 2 hours time we built 3 umbrella-cookers and 3 fun-panel/cookit cookers. We started some cooking tests around 4.30 pm. The sunmoved fast and we had to adjust the cookers all the time. Than came the wind and he blew our pots away. Finally we cooked a simple meal on okno’s electric plates.

DIY solarcooker workshop

Presented as a preview for our upcoming-series
‘creative eco/techno gardening forgirlsandboys’ (2009-…) :
the cook, the artist, the engineer and their urban garden;

OKNO/so-on invites you to participate in the mini-DIY-workshop:
++++ HOW TO BUILD A SOLAR COOKER ++++

paracuina1.jpg cookit_small.jpg barbacoa_solar.jpg

thursday 24 july 2008 at OKNO, 01pm till 6pm
en petit comité
drinks available, food only if we succeed!
free entrance for women and transgender (boys, be inventive!)

what?
A Solar Cooker is a device that allows you to cook food using the sun’s energy as fuel.

why?
+ Solar cooking is the simplest, safest, most convenient way to cook food without consuming fuels. But for hundreds of millions of people around the world who cook over fires fueled by wood, solar cooking is more than a choice.
+ Moderate cooking temperatures in simple solar cookers help preserve nutrients.
+ Smoke from cooking fires is a major cause of global warming.
+ Many solar cookers are portable, allowing for solar cooking at work sites or while pursuing outdoor activities like picnics, trekking or camping.
+ and so much more … read:

Barefoot Women Light Up India :: by Neeta Lal

For a video report on the solar engineers of Hyderabad, check the category 'media'.

Four dark-skinned women in multi-hued saris hunch over a solar power-generating circuit at the National Institute for Rural Development (NIRD) in Hyderabad, fleshing out details about solar lamps and panels for Indian villages. Chennamma, Yelamma, Kalavati and Zayda, all illiterate women in their 30s who previously worked as stone crushers in South India’s quarries, have left the furnace-like heat of their previous jobs to use the sun to a better purpose. This is the Women Barefoot Solar Engineers Association of Hyderabad. Exploitive employers, 10 hours of backbreaking labor and a long wait in queues to collect a wage of a dollar a day pretty much summed up these women’s bleak existence in the quarries. But today, after the institute’s Rural Technology Park helped train them as solar engineers, the women manufacture and maintain solar lamps and travel across India’s vast rural landscape to install solar power generators.
