Any thoughts on the idea or the thresholds?
For over voltage, sounds like a "crowbar" device for aero-planes. In an over voltage situation, a 'crowbar' is dropped across the feed wires, blowing the fuse(s) and protecting the avionics. But I wonder how many times this had happened on a Connie? Not many I'll venture.
If you're programming a PIC, encapsulate it but allow for ICSP. Just in case trip voltages need to be modified after production.
LV shutoff. Set it ever so slightly below idle state. But this may vary according to the battery chemistry. Flooded vs AGM vs Oddysey vs
This way the user can shut off their bike and know the accessories on the relay will [eventually] shut off too. And hopefully not start back up? But see below.
If a person wired his GPS into this relay, would the relay shut down when said person has to wait at a stop light (at night) when he had his aux lights on too? Could be a bad scenario.
You code for Microchip/Atmel devices?
