HOW TO BUILD OSCILLATORS: Gate Schmitt Trigger (CD4093) … for modulation
Beginners Workshop!
No experience or knowledge is needed!
The workshop will be hold in German and English.
In this circuit bending workshop we will build an experimental sound machine on the basis of a digital logic chip that was not made to create sound, anyway we do it. And it just can sound beautiful…. noisy!
We use a CMOS Quad NAND Gate Schmitt Trigger (CD4093). That chip has 4 inverters. With a few capacitors, resistors and potentiometers it will become 4 oscillators that modulate each other.
We start with the basic circuits and I will show you how the different electronic elements influence the sound. Then everybody will experiment with different values of the pots ect. until you find the sound/modulations you like. CMOS produces square waves…but they are not really clean.
Dealing with this chip is a somewhat advanced electronics, but you do not need to worry – we try until you get it. You will learn how to use a breadboard and how to solder (if you do not know yet).
What will be provided:
Some components to get started: resistors, capacitors, potentiometers, switches, battery clips, audio outputs, the solderboard …. and most important the chip (CD4093)
What the participants should bring: a soldering gun, solder, a breadboard (if u have one), nippers, wire, a small amplifier (or computer speakers), headphones, croco clips, a 9 Volt battery (very important)
When: Wed & Thurs 5 & 6th of March from 16:00-22:00
Where: NK: Elsenstr. 52 2HH 2Etage 12059

Instructor:
AA..LL is a Berlin based artist, she studied Fine Arts here till 2009. In her experimental sound collages with self built electronics and taped reality she responds to the movement of body and mind, affected by our rushing era. (….people call it minimal, noise, drone, a telling of a story… )
AA..LL played at international festivals like WRO 09 (Wroclaw,PL), re:new (Copenhagen, DK), transmediale.10 (Berlin, DE)… as well she was performing at Loos Foundation in The Hague (NL), Laznia Art Centre in Gdansk (PL) and at Goethe-Institut in Dhaka (Bangladesh)…
