I am new to linux/LMCE as are so many of us. I have, until recently, used linux like the speech function on Stewie's mac. "It installed... Yay". I compiled some java a long time ago with it... and then LMCE gave me motivation.
A great number of automation products provide 4-20mA feedback, with range sets that trigger different events. It is my goal to build such a thing for LMCE. This way I can implement modular projects which are not tied to specific control modules, and use cat5 for power, feedback and control.
I will begin here.
