Hello,
It's been a long time I posted on this list («Art» effect maybe). I Just wanted to let you know about the Liberlab project for which a Python software and a Python module is available (and a Squeak one also ...).
To summarize, it's an Open Source very
low-cost interface between the digital and the physical world, a sub 15 €/$ «pocket size» digital lab (4 analogic
channels 10 bits acquisition, 6 digital inputs/outputs).
Apart from initiation to scientific
experimentation, Liberlab could also be used to learn about robotics,
automation, human-machine interface or interactive arts.
The
heart of the project is based on the ongoing improvements of
microcontrollers. These low price integrated circuits are like tiny
and autonomous "computers" used in many devices (DVD
players, cars, etc.).
Instead of using them in an autonomous
way Liberlab combines the computing power of a PC with the commands
and measuring capabilities of the microcontroller.
The modular
and open design of Liberlab aims to encourage original uses
particularly in the field of education.
Liberlab is available
under the Free GPL licence (firmware in C, Software and
module written in Python).
I'll present Liberlab at the Libre Software Meeting 2006 (France, early July) and perhaps at EuroPython 2006 for those interested.
The English documentation is quite scarce but growing (some screencast should be available in few days to give an idea of the speed and « dynamics »).
