I want to sort of brainstorm some features and ideas for my next project.
At the moment I have installed a tv in dash, tv tuner, road angel, sat nav and phone charger, that all switch on when key is in the on position or engine is running, powered from cigarette lighter.
I want to change this to a seperate circuit where power is taken from the battery and the cigarette lighter is used to switch it on.
Ideas so far:
1. Have a time delay to allow charging and running of items after ignition is off.
2. Battery voltage level monitor and voltage display.
3. 3 operating modes - on / off / on only when ignition is on.
4. Also need a filter to block noise from alternator and engine.
Cant think of any more at the moment. Will probably try to keep as simple as possible......but might get carried away.
does anyone have any other ideas that I could add before I start designing it?
