Step 7Part 6: Adding the control box and hopper
Mount the control box on to the j-shaped piece of metal with a screw and then mount the other end of the j to the bottom of the chasis. Run the wire wrap along the bottom and attach the wires from the motor to the wires from the motor controller. Connect the DirPin switches to the wires that correspond to the them and hot glue them to the points where you want them to be triggered (ie: DirPin switches should be at the full open position and the other should be to about 1/2" to 1" from the can ejection hole (square hole in the bottom board).
Now grab an empty soda box and cut a hole in it so there is a cool looking window; this is now our can hopper. Now take the hopper and a piece of the top or bottom of the 1"x5" boards we made into a crusher and a can retainer mount, and paint them (sanding is not needed for the soda box). Now mount the wood aginst the "box" at a 45 degree angle, so that the box will freely drop a can into the crusher once the last can is gone (the angled board is for spacing). Now mount the can hopper to the angled board on the "box."
A support needs to be made that holds up the hopper and the StartPin switch. This can be made with small scraps of lumber. I made one from a small rectangular piece and a square piece. Cut a slot in it so the switch can fit in it. After you sand it down and paint it insert the switch and use a piece of cardboard to lengthen the switch. This switch extender is made by a rectangular cut of cardboard. Slice the cardboard piece long ways (like a hotdog bun) not all the way through. Fold it in half using the slice and then glue it around the switch. Install the support so the switch will be flipped when a can is in position to fall in the crusher.
Time to wire the switches! Lets start with the DirPin switches, these badboys are wired to act like one switch. Wire the power (5 volts) to a common terminal on the closer switch, then make a jumper from the common pin from that switch to the common pin of the other DirPin switch. Now wire pin13 of the arduino to the normally open teminal of the closer switch, then like the power terminals, jumper the normaly closed terminals together. Now you are almost ready to try it out.
