I want to use an arduino to have my dorm room open with my phone and/or a keypad
I can't change anything that I can't change back
What would be the best way to have the door open from the inside (mechanically) that would be easy to put back afterwards and that wouldn't ruin my door's ability to open with a key? I can deal with the actual programming etc easily, but the actual mechanism has me scratching my head as to what the best method would be.
Get a towel rail that you hang over the door
Some rope, tape it to the handle. The tape won't hold but wrap the rope around and around and around until pulling the type pulls the latch. Rope goes over a pulley on the towel hanger. Other end of rope tie it to a paint can and fill with sand or bolts until its a decent counterweight.
Drive pulley with motor indirectly, use a rubber wheel as a friction drive or a belt and pulley to turn the main pulley.
Ps you are a raging faggot for doing this
The thing is, it needs to drive the fairly heavy interior handle. There's no lock button, it just auto locks (and I want to be able to open it normally, so I don't want to cover the entire knob)
The reason I want to do this is because I'm incredibly forgetful of my keys (pretty bad adhd) and getting the door unlocked is a walk across campus + 50 bucks.
The door is a knob, not a handle.
This is a good idea but the lock can't remain unlocked, it automatically locks and the only way to open it is with the key or by opening it from the other side. Also, I can't install the hardware for a new lock in a dorm room.
The answer here is. Unhang the orginal door and put in storage. And hang your own store bought door and put all your electronics in it. Honey comb style doors will be easiest for a retard like yourself.
\thread cause my idea is just that good. Any further questions instead of shitposting up a slow board with dumb questions. Head to /ohm/
>I'm incredibly forgetful of my keys (pretty bad adhd)
Just tether them to yourself, like everyone else.
Most people use pockets, lanyards, carabiners; I know others that use hk clips, alice clips, mash rings. There are a hundreds of solutions here.
Also, you fucked up by not providing pictures. Images of the following would have been helpful:
door (interior / exterior)
knob closeup (interior / exterior)
edge of the door (showing deadbolt, latch bolt)
OP is a faggot for wanting to do this to his dorm for the reasons he specified, but it would actually be kind of cool in a roommate situation, especially for pets.
Put a small motor and rubber wheel on the bottom opposite the hinge, touching the floor. spin it one way to close, other way to open. Solenoid latches and unlatches door, NFC reader + tags on your pet's collars.
NFC found = open x amount for y time, close again.
