How can I run a motor off of USB and make it turn real slow?

[brand0nized]

Hi folks. I know this isn't the right forum, but you guys are my only (electrically-inclined) friends...

I want to run a motor off of my USB charger that outputs 5V at 2.1A, and I want to make it turn really slowly.

Why? I found an app that gives me points for watching videos, so I'm going to rig up a stylus on a motor to go up and down right over the spot where the "Next Video" button is, so I can rack up points when I'm not in my room.

Us college kids need some spare cash... And a life...

Use a 5v Solenoid? (this is a electromagnet that goes in and out, so good for this "tapping" application)

Then you could control it with all manner of things from a 555 chip, to a Arduino micro-controller (Arduino would be a really good device to use for this project as you will learn very simple code to set when the Solenoid is on or off)

how about an arduino and a stepper motor, i got on code that makes one stepper runs about 0.1rpm or even slower

Clock movement using the sweep second post?

While the mechanical approach is admirable for us DIYers....how about using a "Mouse Macro?"

You can simply record a macro which clicks the mouse button every n seconds and "loop" it.  No soldering required 

Step 1.  Record Mouse Macro
Step 2.  Profit!

That's the first thing that popped in my head too

Where's the "Best Answer" button? I think you've solved my dilemma.

In Morrowind, I once left a character swimming into a corner by wedging a matchstick into the keyboard and wandered off for a few hours (easy way to level some kind of skill in the game, I forget what.)
