NC Systems: pioneering the Reverse Polish Revolution.
 

 

The goal of this project is stated as:

"To design and manufacture the prototype of a machine that can separate various batteries based on their size and charging condition."

Specifically, the machine must work with AA, C, D and 9V batteries. A more detailed description can be found here.

 

Follow the progress of the project from day one to its current state:

03/9/22 - The project has its humble beginnings...

03/9/23 - After countless hours spent toiling in the lab, we've developed our first solenoid!
03/10/8 - An experimental circuit designed to drive a stepper motor (at left) forwards or backwards, depending on switch configuration, and at different speeds, when the magnitudes of resistors R1 and R2 are varied. A flashy light show is included to increase the entertainment value of the circuit.
03/10/8 - An extremely well-ordered circuit. The various components will probably be reused in the battery sorter, but remember: entropy can only increase.
03/10/8 - A closeup shot. Note the non-burntoutedness of the green LED.
03/10/16 -Click here to view a video of our completed Assignment 3. The PIC was programmed to blink 4 LEDs sequentially with a frequency of 0.25Hz.
