Texasclodhopper, you are absolutely correct i have given basically 0 info on the project. Below is a link to a video by a physics teacher, he created a "string shooter" which uses 2 DC motors spinning in opposite directions which accelerates a loop of string through two wheels. This causes the string to display some interesting properties, like behaving like a rigid body.

My project will involve creating 4 units. each unit will be 1 string shooter. (2 motors to accelerate string) (1 servo to control launch angle of the string) the 4 units will be lined up so that two units are facing to the left, and two facing the right. (from a front POV). The PWM pins on the 20M2 chip will control the velocity of the string shooters by controlling the motors. [I am using two MOSFET's for each unit, 1 for each motor, each unit will be driven from one PWM pin.] The SERVO's will be mounted in such a way that the string shooters will be able to rotate ~120 degrees. Basically functions like the manually operated angle control from the video.
I am technically building 2 of these projects. the first will be for me to use in 1 and 2 below, the second one will be used for #3 below
The project will have 3 purposes.
1- My capstone MECHATRONICS project, I am in a mechatronics certification program at my local CC (Community College) and this is my last semester. The project needs to leverage a microcontroller and PICAXE chips are the department standard.
2- The program (Sierra College Mechatronics) is working with a local makerspace (HackerLab) and a sponsor (CitiBank) to hold a contest within the Mechatronics department for students in the mech 90 (capstone class). In order for a project to entered into the contest it must serve a humanitarian goal. My project will meet this goal in the following manner. Using a conductive ink pen, and the touch pins of one 20M2 chip i plan on developing a easy to replicate control board (photo paper, with traces drawn with a "Circuit Scribe" pen.) that i will take to school children. I will have them create their own control boards and using their "First Circuit" they will get to play with the string shooter. The humanitarian goal of the project is to put electronics into kids hands and getting them interested in learning/playing with electronics. I remember from when i was in grade school the things that made the biggest impact on my learning were the ones i could physically see, and touch.
3- I want to create a youtube channel partially inspired by the "Queen Of Shitty Robots" Simone Giertz. This channel will be the first phase of my plan to start my own business as a creative consultant. I will be sending one of the projects to TESTED a youtube channel created by Adam Savage from mythbusters. I would like to join the tested team and if TESTED finds my project amusing to play with we can set some goals of where they would like me to be as a channel before I was able to join their team.
Below is a link to Simone Giertz's youtube channel. She makes some pretty funny projects worth a watch if you have some free time.

If there is anything else i can explain about my project and/or goals please feel free to ask. Thanks for the input the both of you,I am fairly positive i will be able to complete all three goals of my project using 3 20M2 chips per project.
