Great info - thanks! I know I would certainly appreciate you putting together a schematic for wiring up the Pi when you get a chance - just ordered mine, and can't wait to start playing with it . . .

Adafruit, has rolled their own distro that has the I2C/1-wire, and many other features pre-compiled.

I'm looking at several different options right now that will comprise a multiple thermo/SSR setup.

That's what I was looking at running with to start. Just ordered some additional stuff from them (i2c 16 port i/o expander, 8 channel SPI ADC, etc.) for basic testing and prototyping.

I'm thinking of using an Aduino for the hardware heavy lifiting, which would include a small 5" GLCD touchscreen and the RPi as the web/wireless interface.

Ordered mine today, I already have an Arduino 2560...now to figure out what to do with it all!!!!

I've been looking into the rasperry pi as well. Has anyone checked out http://www.proview.se/ ? It looks like someone on their forum has compiled it for the RPi. I was thinking that it would be slick to use proview.se for the controls and host interface. Then connect to the interface via VNC or web using an iPad or android tablet.

My plan is to take my networked temperature monitor, and add support for the ds2406+ 1-wire switch which would control SSRs for my RIMS and pumps, use the 5" GLCD with touchscreen for local monitoring and control, and then feed the data to the RPi for networking and web monitoring, control and datalogging.

My investigations so far seem to show that the 1-wire on the RPi is still a bit wonky, but the I2C is solid. I would use the I2C bus for communications between the Arduino and RPi.

I have several different Arduino boards, but plan on using the Mega2560, with its large memory and program space and tons of I/O.

Just my $.02

Great stuff Steve. I was thinking of going with a hacked router a la uberfridge but the memory constraints might prove to be too much of a pain. This sounds like a great alternative.

I would think piggybacking an Arduino on the Raspi might make the IO a bit easier for most people. Plus these Arduino PID libraries might speed development: https://github.com/br3ttb

Got the parts in yesterday to make my bi-directional level shifter so that the Arduino's 5v I/O doesn't damage the RPi's 3.3v I/O. Breadboarded a shield for the Arduino Uno, and got the two communicating over I2C.

I don't want to hijack this thread, so I'm taking my progress over to my Arduino thread.

Looks like this is gonna be fun...

My RPi arrived today. I'm going to build a Pi based brew controller too.

I am still waiting for my relay board to arrived. And I need to build the rest of my brewstand first too...

Anyone have a one wire bus working with the 18B20 temp sensors ?
