To attach our dowel to the drive shaft of the second motor we simply drilled a hole slightly smaller than the drive shaft on the motor and then pressed the dowel onto the shaft. This provides a surprisingly strong result.
Here is an example of some of our leds we used for our shots. We simply taped a battery onto the led and poked a hole in the ping pong ball with a small screw driver to press the led into the ball.
Here you can easily see how the ball evenly defuses the light all the way around it.
And finally for those who need a little more instruction… we taped the LED’s to the end(s) of the second arm.
