Sean I have been playing with the calibrator circuit that you sent and have a few questions. First, is the "Alarm Clock In" a contact closure? Exactly what does the output look like? Thanks in Advance By the way- I am planning to start machining my version of the VBB. I have wired all my boards and need something to test on.
