Make a techie CD clock with your kids

If you and your older children have always wondered what’s inside an old adding machine or transistor radio, or what’s behind the face of an alarm clock, give this activity a try. Then turn your find into a one-of-a-kind CD clock. You’ll quickly discover that curiosity can stimulate an abundance of creativity.

First, put the machine, such as an old alarm clock, a windup toy or a radio, on a work surface covered with newspaper. With screwdrivers, hammers and pliers, remove the cover of the machine and begin exploring. If the machine has an electrical cord, clip it off for safety’s sake. Remove and properly dispose of any old batteries and glass parts.

Try to figure out how the machine works, and enjoy speculating on its mysteries. If the machine has small and sharp gadgets and gizmos, don’t leave them for younger kids to explore without adult supervision.

Now, use your finds to make a CD clock that any “techie” would love!

•Cover the label of an old CD or DVD you aren’t using anymore with a piece of poster board or construction paper cut to size. Glue in place. On the front of the CD, using parts from the insides of the machines or radios you took apart, arrange parts to create the face of a clock. Diodes from radios are especially good for this idea.

•Different shapes and sizes can represent the numbers 1 to 12. Choose a specific shape for the hours of 3, 6, 9 and 12. Smaller parts in various colors can be arranged evenly between them to complete the face. Glue them in place with strong nontoxic glue. Purchase a quartz battery-operated clock mechanism (available at craft stores) and insert through the center hole of the CD.
