It’s easy to build up a “junk box” of items you can use to build projects seen in just about any-thing you can imagine.
Many of my articles take advantage of found components, often picked out of trash bins. Just because an electronic device has failed at its original task doesn’t mean it can’t perform other tasks. Castoffs can be recovered and the parts repurposed in countless ways.
Recently, my trash-picking adventures turned up a discarded laser printer. I set about finding what wonders were waiting beneath the plastic covers.
JACKPOT OF PARTS
My first discovery was the main circuit board. Once I stripped the heat shields off, I found over 50 nonproprietary electronic parts, including capacitors, resistors, voltage regulators, transistors, transformers, coils, and integrated circuits. Jackpot! A couple of boards like this, and you’re on your way to building a backup supply of parts for future projects. A second, smaller PC board also yielded numerous useful components.
