• Machine Screw 1in long
• washer
• 2X nuts that fits the machine screw
• E600 Glue (or any strong glue)

Procedure:

1. Print all the parts as separate parts. Only the base may need supports.
2. Glue the wheel and the Wheel Pulley attachment together. Make sure the holes are concentric.
3. Assemble the Motor Pulley attachment with the Dyno DC Motor shaft. It should be press fitted to avoid slipping.
4. Connect the positive side of the LED (the longest side) to the red cable from the Dyno DC Motor and the shortest side of the LED to the black cable suing the clip included with the Dyno DC Motor kit. (you may do soldering or any other type of connection you find suitable for the application)
5. Assemble the wheel in the following order
   1. Now that the wheel and the Wheel Pulley attachment are glued together and dry, insert the machine screw from the paddle side for the wheel to the bearing side.
   2. Insert the washer so that it makes contact with the bearing.
   3. Insert the Wheel Mount and finish with securing it with the nuts. Make sure it is not to tight and that the wheel can rotate freely on it axis.
   4. Place the Rubber Band in the Wheel Pulley attachment and assemble the Wheel Mount to the base.
   5. Assemble the Dyno DC Motor Mount to the base.
   6. Slightly pull the rubber band from the wheel to the Motor Pulley attachment.

Troubleshooting:

• The Dyno DC Motor requires at least 1200 RPM to generate around 3V.
• Check the rubber band tension. If it is too tense, you may need more power to get it moving. If it is too loose, the rubber band may slip and not have enough friction to move the shaft.
• If the faucet pressure is not be enough, try using a cup and pour the water at 7in height or more the generate enough pressure to move the paddles
• Make sure the metal part of clip that connects the motor with the LED is actually touching the metal part of the cable and not just biting the rubber covering the cable.
