5 Basic Tools You Must Have for DIY Electronic Repair

We all have electronic devices in our homes. Some of the most common electronic devices found in households include smartphones, televisions, audio systems, video game consoles, and appliances. If one of these devices were to malfunction, it would cost you anywhere from $50 to $1,000+ to replace it. Certain electronics cost more than others, of course.

Alternatively, you could hire a technician to repair the electronic device for you. But even then, you’d still have to pay them $50+ per hour for their services. What if you could avoid spending all this money and repair the electronic device yourself? All you need to do is purchase five basic tools. Then you can use them whenever you need to repair an electronic device, and it won’t cost you a penny more. And to learn about basic electronic circuits, components and devices, you can read the articles on electrowebs.com or other electronic sites on internet.

Let’s examine those five tools below.

1) Soldering Iron

A soldering iron is a handheld tool that can melt a fusible metal alloy so that two metal workpieces can be adjoined together permanently. Electricity is used to heat the metal tip at the end of the soldering iron. You put the iron tip on the metal that you want to melt and bond.

Electronics consist of many different metal components. If specific metal components no longer have a connection because they’re old or worn out, a soldering iron can help reestablish a stronger bond between them.

2) Vacuum Desoldering Pump

A vacuum desoldering pump is a handheld device used for removing the solder that you’d find on a printed circuit board. The classic desoldering pump is a manually operated device, but the vacuum desoldering pump is electrically operated. Think of it as a solder sucker.

If you want to remove metal components from a circuit board, you would need to use the vacuum desoldering pump. It is much easier to use than the manually operated pump because the electrical operation makes its solder removal automated. The device looks like a thick pen, which lets you hold it very easily in your hand.

3) Multimeter

A multimeter is an instrument for measuring the electrical voltage, resistance, and current of an electronic device. It is a standard device used in both the electrical industry and electronic industry. Electricians and electronic technicians always have a multimeter on them to measure the electrical values of the devices.

For a DIY electronic project, you cannot go without a multimeter. It allows you to take the proper electrical measurements so you can stay safe while working on your projects. It is better to use a digital multimeter such as Sanwa PC7000 because it is more accurate, and it is easier to operate.

4) Screw Drivers

You probably have a screw driver lying somewhere around your house. However, it is likely too big for the screw drivers you’ll need for performing electronic repair projects yourself. But keep the bigger screw drivers handy because you might need them for the outer shell of your electronic devices.

In many cases, you’ll need extra small screw drivers to remove tiny screws from the circuit board or to install the screws tightly into the board. We recommend that you purchase screw driver kits with screw drivers of different sizes in them. Then you’ll always have a compatible screw driver available for the screws of your electronics.

5) Pliers

Pliers are another tool you might have lying around the house. They are generally used to hold or grip metal objects securely in place. Sometimes they can remove screws or nails if your screw driver and hammer cannot do the job. You could also use pliers to cut wire and bend objects.

There are multiple types of pliers available. Some have side cutters on them while others have flat metal tongs. We recommend you purchase a kit with various types of pliers in them.

How to Make Earphone and How does Earphone Works

There is nothing as exciting as making your earphones and using them. It might look complex, but the science of how earphones work is very easy to understand. Once you understand it, you can easily make your earphones.

How Do Earphones Work?

Before we look at the ways in which you can make your earphones, let us first discuss how they work.

Here are some basic principalities of how an earphone works:

It’s all about completing the circuit

At its basic level, an earphone is all about completing the circuit. In as much as an earphone may look so complex, it is just a loop of wire with currents passing through it. Electric currents interact with a magnet that pushes the air, which produces the sound. So, to produce electric currents, you must complete a circuit.

Parts of earphones

To understand how earphones work, you will need to know the different parts of earphones and their work in helping to produce sound.


Speakers of earphones are just like other speakers, just that they are smaller and put very close to your ears. They are usually too small that they fill the ear’s outer void.


Transducers are the devices responsible for converting energy from one form into another. In an earphone, there are two transducers that convert your device’s energy into sound energy. Just like any other circuit, an earphone has a conductor that draws energy from the source and provides it to the load, which is the transducer.

The Jack

The jack is what connected the conductor to the source. The tip of the jack has the sleeves that power the right and left earphones.
