Battery Packs:
For this project I chose to use two battery packs for the motors, a 2 and a 4 battery style pack with standard 9v connectors on them for easy replacement. Both packs I picked up at our local over priced electronic supply vendor for 6.00 total.
Screws:
For this project we will be connecting the sprocket to our aluminum arm with a couple ½ inch long 8-32 screws and nuts. Est cost .50
Zip Ties:
The majority of the connection points in this build will be fastened with zip ties. We chose to use zipties because they are cheap, easy to fasten and easy to remove so we can reconfigure the design this produces with ease. Est Cost 1.00
LED's:
For this project we will be using some standard 5mm leds. The colors are your choice but I highly recommend using some RGB Fading LED’s for a great effect!
Est Cost 3.00-5.00
Ping Pong Balls (optional):
So the final part we used in some of our shots are simple ping pong balls. These simply help to defuse the light of the led so that if the LED is not pointed at the camera it is still visible. This is good for 3D configurations. Est cost 1.00
