Switchable Power for OBD Sensors
I would like to develop a manual (i.e toggle switch) and automated (i.e fusion brain) power controller for OBD sensors. I have found that one of the biggest drawbacks to using integrated OBD software and a car PC is the power drain by leaving the OBD sensor connected.
I plan to use :
Along with a fusion brain as well as the manual option to allow me to keep the cable connected but turn it on or off without it draining the battery.
Once I have all the wiring figured out and pin outs I would publish it up so the community could create they own to augment their car pcs.
I would like the fusion brain and the cable as part of the grant if possible
Questions or thoughts?
