I am trying to make a voltage regulator that converts voltage from 12v to 9v, at first i wanted to use a resistor, but someone told me that, it wouldnt work so great b/c I am trying to feed those 9v to a transmitter and the current will vary depending on how far the transmitter is from the receiver. My friend drew this circuit for me and told me that this would take care of it. Can you please describe step by step how this circuit convert and regulates voltage. I do now how a transistor and resistors work but I am not sure how the diode works and how all these three devices are working together in order to regulate voltage and current. Thank you (PLEASE BE DETAIL IN YOUR DESCRIPTIONS, I REALLY WANT TO GET DIFFERENT DESCRIPTIONS FROM DIFFERENT PEOPLE, SO I CAN UNDERSTAND IT BETTER)

PS. I am making this circuit for educational purposes, I know I could easily buy a chip or a presicion diode that would regulate the voltage and current. Thank YOU
...transmitter operates at 9v and consumes up to 100mw at its maximum, but that is at its maximum, it can probably operate at less.
****UPDATE****
ALL THE PICTURES ARE FROM THE SAME CIRCUIT BUT FROM DIFFERENT ANGLES, HOW DOES IT LOOK?

IS A 1.2K RESISTOR AND A 9.1 ZENER DIODE, TRANSISTOR I AM NOT SURE ABOUT THE DETAILS, ILL FIND OUT SOON
