*Windshield Wiper Motors (Quite substantial, Continuous Duty, 2-3 amps@15VDC) with gearhead!
 
          I recommend the ones from 1990's Toyota Corolla's. Be sure to bring your 10mm socket wrenches!

=== Cellular phones ===
 
Full of incredibly tiny electronics, but for automated manufacture, many are in modules joined by contact springs instead of solder or connectors so many parts come right off. Small speakers, mic, power connector, SMD bulk caps occasionally, tiny eccentric weight vibration motor. A few models have display modules you can find specs for.
 
  
Don't forget about the gold on the boards...front and back.

Power supply is useful as a unit, or can be taken apart for transformer, caps, diodes, and similar. There are usually some LED and switches on the end of wires that plug into header blocks. They also may have CD DVD Floppy Drives see separate discussion. The connecting wires are often useful, sometimes taking the connectors off the mother board makes them more useful. Individual boards may be useful as they are. The mother board is not usually useful for its chips, most are too small and specialized for much use. Crystals may be found, not sure if frequencies are useful

Power supply is useful as a unit, or can be taken apart for transformer, caps, diodes, and similar. Many have a filtered input connector which is rather valuable. There are usually some LED and switches on the end of wires that plug into header blocks. They also may have CD DVD Floppy Drives see separate discussion. The connecting wires are often useful, sometimes taking the connectors off the mother board makes them more useful. Individual boards may be useful as they are. The mother board is not usually useful for its chips, most are too small and specialized for much use. Crystals may be found, not sure if frequencies are useful. AT-era PC's often had D-connectors of both sexes on ribbon cables and peripherals have matching cables. Some have RTC modules, others have CR2032 lithium batteries. The big BIOS flash/eprom may be recyclable. Certain vintages have nice SRAM chips as cache. SCSI and other smart controllers have serial eeprom's for settings. Old ethernet cards and cables yield 50-ohm coaxial wiring. Loads and loads of screws in the case.
+
Often have stepper motor and Brush less motors. The old 5 ¼ drives are most likely to have reasonable power steppers. most of the chips then to be too small and specialized for much use.

Card slot if you can get it out. Battery, contacts and charger. Switching regulators. Very nice displays but hard to use. Be on the lookout for EL backlights, though, if you can power them. Nice smooth squares of very white light. Optics of varying types, connectors if you can get them out. Marvels of miniaturization and cramped-space engineering worth looking at in any case.
+
Make sure you discharge high voltage capacitor prior to salvage, if you do not know how to do this find out firs. High voltage transformer ( dangerous ), high voltage capacitor and diode. Good magnets in the magnetron tube. Lots of micro switches. Small motor, motorized fan.
  
=== Floppy Drives ===

Printers
Often have stepper motor and Brush less motors. The old 5 ¼ drives are most likely to have reasonable power steppers. most of the chips then to be too small and specialized for much use. The 3.5" power connector is reasonably easy to remove with most equipment.
+
Often have stepper motors. Plugs, jacks, power transistors, diodes. Gears, shafts and other mechanical components. Control panels may have led's and push button switches.
  
=== Hard Drives ===
+
Stereos, boom boxes, radios
Pretty platters, spacers and stator coils, strong magnets, odd motor or two.
+
Plugs, jacks, power transistors, diodes.
  
=== CD/DVD Drives ===
+
TV
Laser diodes, motors (usually brushless for the cd spindle, stepper for the laser position, and DC for the tray), volume wheels, open/close limit switches.
 
 
 
=== Tape Drives ===
 
Rare. May contain springs under considerable tension! Some have beefy power components. SCSI terminators have resistor packs for picking.
 
 
 
=== Microwave Ovens ===
 
Make sure you discharge high voltage capacitor prior to salvage, if you do not know how to do this find out first. High voltage transformer ( dangerous ), high voltage capacitor and diode. Good magnets in the magnetron tube (WARNING: there may be beryllium oxide ceramic present in the magnetron tube, wear a respirator or N95 capable of filtering out fine dust. do not attempt to take apart a magnetron tube w/o a proper mask, the BeO dust can cause an incurable lung condition or cancer.) Lots of micro switches. Small motor, motorized fan.
 
 
 
=== Printers ===
 
Often have stepper motors. Plugs, jacks, power transistors, diodes. Gears, shafts and other mechanical components. Control panels may have led's and push button switches. Many laser printers have standard type LCD modules. Many inkjets have nice big external power supplies.
 
 
 
=== Stereos, boom boxes, radios ===
 
Plugs, jacks, power transistors, diodes. Audio power IC (TDA2030 is very common). Transformers and power supplies, sometimes symmetrical +-. VFD modules.

May not be a good salvage candidate: There are high voltage dangers and dangers from imploding picture tubes. Also when you are done there is often a disposal fee as the picture tube contains a few pounds of lead. Do not dispose of irresponsibly.

Using a Desoldering station and/or tool is a much better idea.  These are available cheap on EBay.
