Info

The workshop is lead by Marc R. Dusseiller and Andy Gracie.

It is organised in collaboration with the Finnish Bioart Society.

Andy Gracie is an artist working between various disciplines including installation, robotics, sound, video and biological practice. The work he produces is situated between the arts and the sciences, creating situations of exchange between natural and artificial systems which allow new emergent behaviours to develop.

Marc R. Dusseiller is a transdisciplinary scholar, lecturer for Micro- and Nanotechnology and artist. He works in an integral way to combine science, art and education. He performs DIY-workshops in lo-fi electronics, music and robotics, has made various short movies and is currently developing means to perform biological science (mammalian cell culture, microfluidics, live-microscopy) in a DIY fashion in your kitchen or your atelier.


BioElectronix Basics

A great resource about Practical Electronics on wikibooks.

The arduino playground gives a nice overview of electronic components.

4066 QUAD Bilateral Switch

CMOS 4066.png

The CMOS chip 4066 is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals.

from Practical Electronics: The 4066 contains 4 analogue bilateral switches, each with an active-high enable input (A) and two input/outputs (X and Y). When the enable input is asseted (high), the X and Y terminals are connected by a low impedance; this is the on condition. When the enable is low, there is a high impedance path betwen X and Y, and the switch is off.

The 4066 is pin-compatible with the 4016, but has a significantly lower on impedance and more constant on resistance over the full range of input voltage. Therefore, the 4066 is preferable to the 4016 in most cases.

Measuring things

Amplifiers

Op Amp is a short hand term for Operational Amplifier. An operational amplifier is a circuit component that amplifies the difference of two input voltages.
