Broken DVD players contain many useable electronic and mechanical parts
As a mechanical and electronic appliance, a DVD player includes many useful parts for electronics and small robotics projects. Most DVD players have at least two motors, many gears and mechanical bits, a power supply circuit board and a large mainboard. Although modern manufacturing has reduced the size of the circuit boards on most every day appliances, using as many large scale semiconductors and surface mount components, it is still possible to salvage many of the larger through-hole mounted semiconductors for your own use. Older electronic appliances usually have more salvageable components inside, but never pass up an opportunity to collect new, old, broken or working electronic devices for addition to your ever expanding junk pile.
Figure 1 - The power supply board will often contain many salvageable parts
Newer electronic appliances such as DVD players, TVs and radios will usually contain only a single circuit board, often consisting mainly of surface mounted components. But, there will usually be at least a few salvageable semiconductors in the power supply section that can be unsoldered for later use in a solderless breadboard. Larger capacitors, resistors, transistors, coils, and switches will be easy to remove from the board using a soldering iron.
