Salvaging
electronic parts is a must for any DIY'er. You save big on shipping charges, and recycling is good for the environment.
Hack-a-day dissected an old computer mouse and found some useful components.
What useful parts are inside an outdated PC mouse? There are a bunch of sensors and buttons, including rotary encoders that can be used to measure movement in robotics projects. My favorite find is the microchip that glues the sensors to a computer. Learn about all these parts in detail, in the
how-to.
Hack-a-day doesn't delve into the proper techniques for removing parts, but there are a ton of tutorials that can help you get started. It's possible to remove many parts with a simple soldering iron and an absorbent copper braid, called
solder wick. Many use a
solder sucker to vacuum solder away from parts, or a special
desoldering iron. Surface mount chips can also be removed, but they may require the gentle embrace of 400 degree air from a
hot air rework station, or the crude gust of a
heat gun.
