K'nex Counter

This is a counting machine the can count from 0 to 99 I got the idea from the ball counter NorthernF made.

Let's get started.

Step 1:

This is the base and one of the walls.

Step 2:

Attach the motor to the part in the last step.

Step 3:

The wheel is the hardest part because it has ten sides. The numbers are printed and glued on but you can also tape them.

Step 4:

Attach one the wheels on the wall and put the other wall on.

Step 5:

This is the gear that spins the wheel on the other side. Make sure that the gear and wheel are positioned like in the picture.

Step 6:

This is the gearbox of the machine. if the numbers spin backwards add another gear.

Step 7:

This is the other wall and wheel.

Step 8:

Add the roof and the side that shows the numbers then you are done! Have fun counting :)
