How about internet control of some home devices, such as garage door, radios, cable (recording), ... ? Is that too ambitious ? I am open to just about anything that the Pi can be useful for that's not too expensive (retired!). I'm not too knowledgable about Perl/Python but am willing to learn. My main forte is assembly & C.
It looks like your job is similar to some of my work for Cummins (used Intel 8097 in engine control module, written in assembly & PL/M back in late '80s).
I sure we can agree on something interesting.
