Some weeks back we had a discussion about how to switch

a Hobbs meter on and off based on activity at the

3-phase tach generator. I thought we'd 'wrapped up'

that discussion but I found a drawing under a stack

of stuff that apparently didn't get posted. For

those interested in such things, see:

The opto-couplers can be anything with an open

collector, transistor output.
