Electric Spider

Building these spiders put our knowledge of circuits and soldering together.

In this video, the motor has a metal conductor that touches the battery closing the circuit. The motor is wrapped in copper that is from the body of the spider. Since the battery is touching the spider, it completes the circuit, which makes the motor turn on. The motor vibrates making the spider move.

In this picture I labeled all the parts. The battery sits in a basket, which looks like the spider's body. The motor is positioned so that the metal piece can rest on the battery. The rest of the spider is made of copper and solder. I used the soldering iron and solder to secure the legs onto the body and to make the basket, where the battery rests.

This is a soldering iron.

This is solder. I took a strip of this and put it one side of the copper while I took the iron and placed it on the other side of the copper. The iron made the solder into a liquid, but in a few seconds, the solder hardens to create a strong connection.

This is brass. Brass is used to clean off the iron. To clean off the iron, I stuck the tip of the iron into the brass and moved it up and down and left and right so that it rubbed against the brass.
