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

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!! :)











Trying Auduino with Arduino Pro Mini

Miau Miau!!!

here again with some tryingsss and achievements.  :)

Now we wanted to build Auduino (already build with arduino uno)  using Arduino Pro Mini 5V 16MHz and with 30K of ram! (atmega328).

We decided this because we think that Arduino Pro Mini is more efficient, smaller and transportable and synths don’t look so big! ; and even if it looks small and tiny it is extremly powerful!

Next week two tentacles of Pechblenda are doing some workshops in Berlin and we thought that is the best idea to try them there, like this the workshop won’t be expensive as if we were working with Arduino Uno. 20140122_015957

So it was easier than it looked…. hehe…

In this picture in the right we can see the space-craft we build (jjjj). We can also see in front of the protoboard an example of the Arduino Pro Mini. So what we did was:  We dissassembled the previous Auduino and took off the Arduino Uno. We put the pcb with the potentiometers to a protoboard and made the same connections that the old Auduino had. –> those are the black cables connecting the potentiometers to the analog pins of the pro mini, and other cables to connect digital output (digital pin 3)  and Vcc and GND. And about hardware by now that’s all.

About software: we just have to copy the Auduino code and follow the “// For modern ATmega168 and ATmega328 boards //    Output is on pin 3” option.

Then we connect the Arduino Pro Mini to a bootloader for being able to connect with your laptop. And compile and upload the code! With Arduino Pro Mini you need to press the reset button (on the circuit) when uploading. Check http://www.arduino.cc/en/Main/ArduinoBoardProMini for more instructions.

And that’s it!

miau miau!
