Recycle old PCB components

Step 6 Recycled components

Here are the components that I recycled within half an hour of desoldering...

• Capacitors
• Switches
• Audio sockets
• TV plugs
• Resistors
• LEDs
• Transistors
• Motor
• Screws
• ...

Most parts have a part number on them you can Google to identify them. Sometimes you can even find detailed datasheets -- especially useful with oddball ICs like the bipolar stepper motor controllers I salvaged from a flatbed scanner. =)

yeah I try with a component but it didnt work

 its a crap shoot at best but sometimes you can find gold that way

very nice instructable! helped me find useful(very useful) parts out of a broken mouse!

the black rectangular multi pin pts. are difficult to identify from the picture. They are power unites (high current) because of the package. depending on what they came out of they could be almost anything from a SCR, to a voltage regulator to an audio power amp or transistor or a bridge rectifier. I usually try NTE electronics first for a replacement using the some or all f the numbers printed on them. Some are probably contract manufactured and have a OEM number of the device they were used in and may not be identifiable. Good luck and happy recycling!!

I'm pretty darn sure that the black ones on the bottom are Bridge Rectifiers. For those who don't know, Bridge Rectifiers convert AC to DC, or make sure a DC current is DC. The 4 pins are input and output. I could be wrong, but that is what they appear to be.

The 3 pronged black things are most likely Transistors. (Some of them might have little number codes, just google that and you should get your answer) The other things, all the way to the left could either be different forms of capacitors and resistors. Just like with the other components, try looking up the codes on google.

As for the 4-lead IC's, just look up a datasheet.

The unknown parts: The top white one looks like a kind of wirewound resistor, but a radial one instead of the normal axial ones. The yellow box looks like a capacitor, and the kind that is either X-or Y rated meaning it is certified for use in mains voltage applications. X-rated ones go between Live and Neutral, Y-rated ones go between either Live and Ground, or Neutral and Ground, it probably has X2 or Y2 written somewhere. The black thing with the grey square is a Toslink transmitter or receiver. Probably a Toshiba TOTX177. The black cylinder looks like a coil (inductor) to me, and this is logical because coupled with the yellow capacitor it makes a LC-filter used in power supply filtering.

Bottom left could be voltage regulators or transistors. However, because they have 4 pins, I think they may be rectifiers: four diodes arranged in such a way that when alternating current is applied to two of the pins, direct (though not constant) current comes out of the other two pins. One usually adds capacitors to even-out the rectified current.

Middle left 2 of 4 I know. Bottom half black pencil with two wires looks like a coil or a choke. Device to stop interference and voltage spikes. yelow box is a capacitor Bottom left anyone who knows electronics should know them. Voltage regulators and transistors of sorts.

The square things look like power transistors but I could be wrong they could be voltage regulators as berserk said...

bottom left are voltage regulators. although the ones ive used have only been 3 pin.
