Fuscus is the Latin name for the Brown Water-Python. It is also the name chosen for this native Python implementation of the BrewPi fermentation controller.
BrewPi (http://www.brewpi.com) is an Open Source temperature controller for brewing beer or wine, designed and developed by Elco Jacobs. It initially comprised of a Raspberry Pi and Arduino. The Arduino handles the temperature sensing and PID control of a heater or cooler. The Pi provides data logging and a web interface. A serial link joins the two parts of the system together.
I felt that the Arduino was unnecessary as all of the I/O can be done directly on the Pi, although some consider the Pi is not as reliable as an Arduino. I have re-written the Arduino code in Python, which runs on the Pi. Temperature sensors and relays are connected to the Pi GPIO pins. No Arduino is required.
