Hey Guys, Noob here.
I am trying to build a magnetic stripe card spoofer, inspired by the one here:
http://www.instructables.com/id/Magnetic_stripe_card_spoofer/
I know how to write the code, but what i don't know is the wiring side of this project, i don't have a very good grasp on how to amplify the power enough to power the electromagnet.
Help
