COTC Capstone 2009 - Rube Goldberg Device

This is just a run through of the first portion of our demonstration. When the fan and digital voice modulator is triggered, we also had a second QTI light sensor which triggered an LED light display with digital countdown which then released a robot line follower triggered by RF remote programmed using a basic stamp2. For the finale we had a third QTI light sensor that triggered pumps to pump water into a container of dry ice, then a string of red lights lit up around the smoking dry ice. The pumps ran off of a 12 volt car battery. Then we built a circuit on a bread board, using a transformer, to step the 12V DC up to 120V AC to run the lights.The problem was that we didn't get all the final bugs worked out until just before the presentation, so I was unable to get video of the entire demonstration. I wish I could have, but time limitations just did not allow me to.
