Electrical engineering: Digital camera connections

This video shows you how to "hotwire" a digital camera. This video outlines the first step in making our digital camera work in the Bit-zee robot. The required voltage for the camera was determined by adding the1.5 volt AAA batteries (there are three of them) together to get 4.5 volts (because the batteries are wired in series). Since new batteries usually have a voltage that exceeds their marked rating the camera can easily run on the 5 volts that the center terminal of our L298 motor controller provides.

Electrical engineering

Learn about electricity, circuit theory, and introductory electronics. We also have sections that let you get down and dirty with household items, from building your own robot to videos where we disassemble household items to see what's inside.

Bit-zee Bot

This project is a low cost robot made from every day items that are taken apart and described in the reverse engineering section. This project was created by Karl R. C. Wendt.
