Saying goodbye to the power switch....
Why do we worry about auto-off switches... Why worry about cutting a hole in the dash for a power switch? Can't we simply get a good, strong battery and put the 'puter into sleep mode or something? Has anyone tried this?
I've been working out a plan to leave the computer on 24/7 for the last few days (provided you run the car every day or so to charge). To minimize dead batteries, I'd like to power the computer with a second (dedicated) batt. It would need to be isolated from the main battery in that it can't draw power from the main. Now, how the heck do I charge it? Do I need a second alternater or is there some way to allow draining from the main batt only when the alternator is producing power? Could I simply place a switch to connect the batts when the car is running? (nah, I want this to be a hands off system)
I already have a dschmidt auto-off device. I'll try to hook this up to simply put the computer into sleep, instead of cutting the power.
