PVC Pipe and Fittings:
For this project I wanted to focus on budget being a priority and ultimately that drove my choice to use PVC for this build. PVC Pipe is available at any home improvement store and is very inexpensive. We used 3 one inch “T” fittings and roughly 14 feet of PVC pipe to create the basic frame we built. This cost us 5.00
Aluminum Main Arm:
For the main arm on our Light Sculpture we used one half inch aluminum “U” Channel due to its strength, rigidity and its light weight. This cost us 5.00 for 1 four foot length.
Wood Secondary Arm:
For our secondary arm we are using a one half inch pine wood dowel at 36 inches long. Pine or any other light material with good rigidity will work well as a secondary arm. Cost 1.00
Geared Motors:
For this project we will need to use a couple Geared motors. Geared motors provide us with 2 highly beneficial features, the move slowly and depending on the gear ratios you can get a good deal of torque out of them to move a heavy load. It is ideal to use a smaller gear motor to power the second arm to reduce the amount of counter weights needed on this light frame. Est Cost Free - 20.00
Sprocket:
To create a simple and strong connection to the aluminum arm we will be using a sprocket that is compatible with the drive shaft of our motor. It is a good idea to use a sprocket with an even number of teeth for this if possible
