Reusing old soldered components


Hey guys,

I guess this post would be so different from any other ones. Why ? It's about the art of repairing and creating. The reason is. To save money. LOL. I'm a stupid yet good recycling agent. I have tonnes of trash in my room. Parents used to mumble of having an untidy and a garbage store in my workspace. How did I give a response ? One man's trash is another man's treasure.




Electronic wastes. Junk. When collection is ready to throw, there's something strikes my mind. Why I don't I tear off all of the removable components before throwing it? How much did I save? In fact, this not about money or cost reduction. Electronic waste is one part of trash which takes years to dispose completely. What matter most is the impact on the environment. Well, I'm not promoting how green I am. It's just how far I can do to reduce wastage. Even with my little effort.

The tools I'm using to tear off the components out from their root are mainly:

Screwdrivers. To remove screws from its chassis.


Tweezers. Helps in remove desoldered components gently.


Pliers. Helps in remove desoldered components in a HARD way. It can also cut off unnecessary parts.


Marker pens. Jot down something.


The most important ones. Soldering kits. 


Soldering iron.


Test pens.


Cutter blade.



Look nearer to the picture. Most of these were stripboards from projects I have screwed up previously. It also has some consumer electronic products like computer mouse and speakers. Overall, the main components extracted from these trash were:

Digital Flip-Flop counter



Components: wires and resistors.



Low power audio amplifier with LM386


Components: 3.5 mm Audio jack, wires, electrolytic capacitors, coupling capacitor, switch, trimmer and LED.



Computer mouse






Components: LED and IC.




Simple transistors circuit



Components: Wires, resistors, buzzer and battery cap.


Motor driver shield for Arduino


Components: Wires and headers



PSP transmitter. Component: Tiny LED


Old TV remote control. Components: LED and IR transmitter.


PIC project




Components: push button, resistors and wires



PIC project


Component: 9-V battery holder



H-bridged motor driver with transistors


Components: transistors and wires



Temperature monitoring system


Components: wires, headers, LED and resistors



Gaming toy. Components: LED and joystick


PIC project. Components: LED and switch.



Flashing LEDs 


Components: LEDs, resistors and wires



Low power audio amplifier for speakers



Components: ICs, wires and LEDs and capacitors.



AV converter. Components: sockets, capacitors and trimmer.


Low powered audio amplifier for speakers.


Components: LEDs, Capacitors and trimmer.


Optical mouse. Components: IR transmitter and receiver, rotary encoder and IC.


Hand phone charger for car. Components: USB socket and LED.


In total, the extracted components is shown:











Old components should have undergo functionality test upon them. Good components return back to their home now. You too can make a difference by spending sometime with what I have done.

Thank you.
