Wondering what you might find inside an old radio or boombox? In this video, I explain a bit about what the guts of a radio are. There is also a bit of discussion about the tools and techniques.
Taking apart devices that we use on a regular basis can provide a fascinating view of what things are and how they work.
There are photos of this project.
Inside a radio, you can find lots of interesting things. You can take one apart to get at the useful components and systems, and you can learn a bit about how things are made and how they work.

A radio boombox
Finding one or two boomboxes shouldn’t be too hard, but getting enough for a whole class to do this project will be a challenge. If you find them over a period of months, you should be able to accumulate a dozen or more. Getting the radios in this way can be effective, but hey will probably won’t be of the same model or brand.
Set up an area to work.
Everybody near this project should be wearing safety glasses.
Use a screwdriver to remove the screws holding the front to the back of the radio.
Carefully loosen the wires from the case.
Pay attention to how the switches on the outside control the circuit inside.
Check out the tape player mechanism, and cd player mechanism.
Identify each of the systems in the radio: amplifier, radio, tape mechanism, cd player, power source.
You can use the component systems inside the radio for other projects.
Save the parts in a way that will help you use them in the future.
