bio/electro/chemical circuits that we are exploring

THF! Pre-programa + Convocatoria sigue ABIERTA!

THF! cada vez mas cerca, la convocatoria extendida  hasta el 28 de JULIO sigue esperándote. ¿te apuntas?

Pechblenda a tope presenta: FollÓn NoiseXXXY y [gynePUNK BIOlab] laboratorio de diagnosis lowcost

El pre-programa ha tomado cuerpo, un cultivo que crece día a día. En el menú tenemos:

Talleres de programas libres para desarrollar performances en internet,
streaming audiovisual, programación con python, mantenimiento de servidores.
Cybersexo /Seguridad digital para activistas, tunea tu sistema operativo, navegador y correo electrónico para proteger tu privacidad y
mejorar tu seguridad en la red. Producción de contenidos y traducciones de materiales y tutoriales para
colectivos activistas. Debates y charlas sobre tácticas transfeministas en internet, servidoras
feministas, soberanía tecnológica con perspectiva de genero. 
Laboratorios sobre Ginecología auto gestionada y radicalidad corporal, laboratorios de noise, electrónica DIY. 
Proyecciones, y un cabaret con jugosos conciertos y perfos.

Aqui algunas joyitas escogidas que giran en torno a mapeos y rutas, a resignificarlas en diversas dimensiones: espaciales, corporales, emocionales o geográficas.

After Workshop

After three intense workshops, 13 Analgital Synths have been built. All of them working!










Thanks to Where is Jesus? and ZUKUNFT for letting us the space to do the workshop.

Thanks to all the participants.

And specially thanks to Txatxe, that, as a new tentacle of Pechblenda, she helped us during all the workshops and worked with us 24/7.

20140216_235818Debugging with Kasia. Finally it worked! Potentiometers always make us pass through some bad emotions and sensations… :SSS







20140216_235953Final workshop with Dr Nexus, Yann Keller and Jo Frgmnt.








20140217_000035Dr Nexus and Jo Frgmnt. Jo using a scissor as a dremel to make a hole.. always using the wrong tools for concrete actions…

Jo arrived to the workshop as a fresh air information dealer for us! we spent hours talking about chemistry, electronics, live in its way… impressionant!

As Dr Nexus said: it is a BitchBlenda construction!! :)











[safari] [@berlin] AnalGital Synth Workshop “Building an Analog-Digital Synthesizer ”


Final schedule:

On Sunday at 7 pm. 16-02-2014
the place for the workshop is ZUKUNFT

Laskerstr. 5, 10245 Berlin-Friedrichshain, Berlin.

Analogic synthesizers are fun. But imagine if you could program each synth and made them sound and act as you feel like!
AnalGital synths have a lot of possibilities, adding filters like envelopes, delays, decays and others.
With Analog-digital synthesizers we can mostly do what we want to. Adding some LDR (so sound is controlled by light), some Pressure Sensors or Ribbon sensors.

We will understand electronic basis and electronic basic components. we will also understand what is arduino, how it works and its community around.
We will learn how to program in arduino. And how to build a nice sound and noise arduino synthesizer.

Using Arduino Pro Mini, we will be able to build a Arduino based on granular synthesis.

you can hear here and example about the sounds that this synthesizer can make

Needs for the workshop: if possible bring your electronic hardware tools, your laptop and soldering iron, in case you have an Arduino bring it as well l!
After we will make a jam session together with all the new synthesizers!!

It will be a 6 hours workshop, however we can go further if necessary.
the cost of the workshop is 50€.

Please, send us an email here to confirm if you are coming!!!
but if you cannot confirm, and you want to come in the last minute you can come as well!!!!
please send this information to all your friends!!!

thanks to tinkerit for show us how to build one by ourselves.
Pechblenda is a TranshackFeminist Bio-electro-chemical Laboratory <> established in Calafou <>. We work with free hardware and free software and mess around with electronic circuits, circuit bending, repairing devices, noise concerts, experimentation and development, giving workshops and doing tutorials DIY since 2 years ago. We are involved in many different projects and right now we are experimenting with DIY analog-digital synthesizers, between others. We also work with gender issues, and we understand our bodies as another code to be hacked.
The nucleus of Pechblenda is made of 3 heads, 6 hands, 6 ears and 3 tongues. Pin, Julito & Klau. Each of us have different trajectories but always surrounded by the same ideals.
