So the elevator in my apartment building is pretty slow, I want to make a device that can call it for me. I don't want to mess with the insides because I don't wanna come off as a terrorist and I've never soldered before so it seems risky for a first attempt.
The programming part I can handle myself probably. I was thinking about a mechanism where I use a rubber band or similar, the device will release it on demand and I'll have to prime it again every time (though I'm not sure this is viable, the button requires some force to press). How should I go about this, hardware-wise, in the cheapest way possible? I want it to be connected to my WiFi network. What do I buy?
The floor is all mine so neighbors won't complain or anything.

You should negotiate that with manager(s) first, otherwise the'll know anyway and act differently.

How am I fucking with it? By replacing my finger with some other object? It has literally nothing to do with the elevator.

If you can attach things to the wall it's pretty easy with any microcontroller and a servo or three. Otherwise you have to build up from the floor and it's still doable but your girlfriend will laugh at it.

The elevator door opens into a tiny hallway and my door is the only one in it, kind of awkward but better than dying

That's what I was thinking, my question was more about which microcontroller/servos I should buy (talking about the wall method)

ESP8266 or wemos d1 mini (same thing, basically) can operate any servo, and they connect to your wifi, so you could write a very simple android app to push the elevator button.

Any will do. You don't need much processing power, if you're an attention deficit take the arduino if you're gay, STM32 is the way, if you're complete autist mentally challenged literal retard, ESP is your friend.

Imagine a pendulum with a small geared motor and a latch at the top, operated by a different motor, or maybe the same one if you're good at mechanics. The pendulum has a small eraser at the tip, and when it's calling the elevator for you it's unlatched, and the eraser presses the button. Then, the motor pulls the pendulum lever back to where it was.

But is the elevator only going to your floor? Why would anyone install an elevator for a 7 floor building that only goes between two floors?

Unless this is your private elevator, you would be fucking over everyone else on the rest of the floors. Also, you get the opposite problem where when you enter on the first floor you end up having to wait for the elevator to come down from the top floor. So you will have to wait the same amount of time at one end of the trip unless you can remember to disable your automated-button-pusher when you're not home.
