Delta extruder with 28BYJ-48 stepper

I made this yesterday, and the hardware seems to be just perfect for a delta printer with its light weight.
But I could not figure out how to get the motor to work with the ramps 1.4 board.
I am posting this so that anyone with extended knowledge could tell me if I am on a dead end here, or if it is a way to get this little thing running.

If I got the motor to work on the ramps 1.4 I could at least test if it is strong and fast enough for extruding PLA..
Any input here is appreciated:
