Scrapping electronics, What should I look for???


       When I was like 10, I would take apart all of my electronics that were broken, or not broken. Then I would play around with the parts with great curiosity. I once rigged alarm to my bedroom door, by fixing a string from in front of the door. When Someone broke it, the string would loosen a weight that would connect a wire to a motor, which would set off an old fashion alarm clock. It was tough to make, and as you know i would have to re string everytime someone came in my room.

Recently while in a forum, someone mentioned Robomaniac`s tutorial of the beatle-bot. And this tutorial resparked an old intrest lying deep within..

Well my question is: Whenever I am taking an electronic object apart. What should I keep?? And what should I ditch??

Depends on what you want out of it.

ME personally?
I know how to process the metals in electronics into pure products. With the price of gold continuing to go up, I tend to gravitate towards that sorta thing.

After that, High voltage power supplies have some interesting uses as ionizing power sources for electrochemistry rigs.

Permanent Magnets are always interesting.

You should look for and keep Speakers, Switches, Push Buttons, Transformers, Motors, Leds, Oscillators, Crystals, any thing that is easy to remove like sometimes I keep whole circuit boards if it's small and removable or has useful components you can reuse the board too for practice projects. Don't break anything. My policy is if it ain't broke don't fix it..

Battery Holders you never know when you'll need one those, small enclosures some times make nice housing for projects. I found some broken RF switches and kept the Box Parts.

I also keep LCD displays. From calculators, Phones, and other devices. Any kind display that isn't broken I keep those.

Keep:
resistors, capacitors, diodes, LED's, some transistors and integrated circuits (like the 555 timer) relays(maybe)

Ditch:
Microcontrollers and other chips (vast majority in consumer electronics can't be reprogrammed or are specific to the device)
Surface mount components- unless you really have patience

I can see why you would want to keep scrapped components for practice and the such. But considering the effort to solder out a $0.10 USD component it gets tedious. Except diodes, those things are pricey for a component.

Also consider, don't make a nice machine with junk parts.
