Hi,
Did you experiment with this to get values through a serial connection?

Hi Nikos - no, I have not tried that, but I'll investigate, thanks very much for the links. My hope, possibly a dead end but fun to investigate, is to control the heater/fan via Grasshopper. I'd love to be able to do that directly rather than wire up new stuff in between the computer and the roaster.

Haha, that's a crazy and cool idea. As long as you have access to a serial port connection, you can do whatever you need from Rhino. Not mentioning the cool 3D interface you can build !

On my side, I try to detect the crack through a sound spectral analysis. Knowing when this crack occurs could permit to adapt on the fly the roasting program to the characteristics of the beans.Could someone bring a more enlightened view than mine on this issue?

That sounds like it is well out of my league, but I hope you can get there, it would be an interesting development for sure.
