Crazy right? Well not really. I've been forgetting to lock my front door as of late and Ive been bored so I figured why not. So honestly, Im just trying to decide on logistics before I do anything. Ideas below.
Way I see it, there's 4 main components. Reader, motor of some sort, a micro controller, and a power supply.
Reader: Best thing I can find is the ID-20 on sparkfun

Small problem though. Range isnt quite there. I'd ideally like to have the ID card in my wallet and jsut walk up to my door. Having to take out my wallet and putting it up to the door kinda takes the magic. I was thinking of making an antenna for it, but I frankly dont have the knowhow and google hasnt given me much. Maybe something besides RFID?
Motor- I am completely lost on the motor. Frankly, I figure Ill jsut need a torque-y DC motor to operate the deadbolt. Anyone see any holes in this plan?
uC and micro controller I have no issue with.
So, anyone care to poke holes in my plan? Any ideas, hints, warnings?
