Overhead lighting

While waiting for epoxy to cure.. I spent some time on my overhead lighting plan. I am essentially copying what Ed Krantz came up with for an overhead lighting control circuit. It is car-like in operation. I plan for overhead white lights above the front and rear seats as well as in the baggage compartment. These overhead lights will be on a dimmer. I’ll have red map lights also dimmable. I plan to install footwell lights as well as panel/avionics lights also on dimmers. The door pins have magnets in them and I plan to use 4 proximity sensors (1 for each door pin; 2 per door). Not only will these be used to ensure that all 4 door pins are seated (causing a red LED to illuminate on the panel otherwise), but they will also be used in this lighting circuit. These proximity sensors basically act as a switch and will indicate when a door is opened. When opened, the overhead lights will come on full intensity, despite what they’ve been dimmed at, and stay on for a pre-determined time (somewhere around 15 minutes). Of course there will be an override button to disable this feature if you want/need to taxi with the doors open at night. I’ll also likely put an on/off switch on the circuit to be able to disable it during times where the doors may be open for long periods (i.e. annual condition inspection). I put together a quick video on my prototype of the circuit.
