The topic of my project is the internet’s effect on security. I am focusing on implementations that rely on “security via obscurity” and how with the rise of the internet, not only is there no technology who’s back end is not exposed to some degree, but there is probably a web community dedicated to probing it.
The part I am stumped on is the climax of my presentation, a magnetic stripe card emulator. While there is a lot of talk about them online, coming across one that can do more than temporarily emulate one card, is difficult.
My demonstration involves a “brute-force” type of emulator. The closest thing I can find is this diagram:
**broken link removed**
The documentation is sparse at best, further this is my first foray in to electronic circuitry of any real complexity. The solenoid will transfer the pulses from the microprocessor to the magnetic head in a card reader I am building.
The hardware consists of a microprocessor, a PIC16C84, generating pulses controlling the magnetic flux in a solenoid, and some switches and capacitors to control the PIC as well as some transistors to amplify the current to drive the solenoid.
Here is a key I wrote for the symbols. I need to make a parts list, and come up with a working breadboard. Are my interpretations correct?:

Are my interpretations correct?
