If you have to choose just one, pick a medium blade; it will suit most projects. Straight-blade screwdrivers are also available with insulated handles for better safety when doing electrical work. Allen wrenches are used to tighten hex-head screws, which are sometimes found on ceiling fans, light fixtures, and appliances. It's a good idea to own both a metric and a standard set of Allen wrenches. Tongue-and-groove pliers are known by many names, including channel-lock , groove joint, tongue-and-groove, and straight-jaw pliers.
This tool is most often used for plumbing work, but a pair of tongue-and-groove pliers also has many uses for electrical projects. It will see frequent use for removing knockouts from metal electrical boxes, tightening cable clamps, and adjusting expansion-type ceiling fan boxes.
Perhaps the most important specialty electrical tool you can own is a voltage tester. A voltage tester is used for a quick safety check to make sure there's no voltage in an electrical wire or device before you start working on it.
Non-contact voltage testers, powered by batteries, are the simplest and safest types of testers because they can detect electricity just by being near an outlet slot or wire. This is a tool every DIYer needs in the toolbox. It will be used for virtually every home electrical repair project.
Another essential electrical specialty tool for homeowners is a good pair of wire strippers. Wire strippers are used to cut and strip insulation from electrical wires. A wire stripper tool has a row of gauged holes for stripping wires of different sizes, and it usually includes cutting jaws for trimming the wire ends. Some types are combination tools that can also be used to crimp wires and to strip the vinyl jacket off NM cable.
Along with a voltage tester, this is perhaps the most important specialty electrical tool you can own. It makes sense to invest in a good set of wire strippers, as it will serve many functions. Another essential specialty electrical tool is a pair of needle-nose pliers also called long-nose pliers.
It will be used for bending and twisting wires whenever you are making screw-terminal connections. The long, narrow tip makes this a great tool for detailed work. Most needle-nose pliers also include cutting jaws for trimming wires. A pair of linesman pliers is an electrician's do-it-all tool. It has a squared-off end that is great for twisting wires together, a center cutting blade for trimming wire, and a grip area between the handles for pulling wire. Casual DIYers may be able to get by without this tool, but anyone who does regular electrical work will want to own a pair of linesman pliers.
Diagonal cutting pliers, sometimes called side snips or dikes, are used to cut wires. A socket wrench sets that include nut drivers, hex drivers, and starters in assorted sizes will come in handy during the assembly work of electronics project.
Pocket Knife will be useful when one need to cut PCB, wires or remove some cooper from the printed circuit board. Maintenance Tips Of Electronic Tools. Good quality tools that are being purchased can last a lifetime if they are taken care of properly.
Ensure that the tools are used only for their intended purposes, keep them lubricated with a light film of oil to inhibit rust, keep the tools clean and sharp, keep the soldering tips clean and well tinned and ensure that proper use of the tools are always adhered to by following the instructions of using the tools.
Quick-turn PCB Prototype. Join the electronics events to enhance your knowledge and network with other professionals in this industry. Electronics Project Design references and tips for high school students, teachers, colleges and university students, electronics hobbyist and electronics designers.
Join electronics design contest and win prizes. Test your hardware and software skills against the best designers from the rest of the world. Battery Tester Project. Design and build a battery tester to test dry cell and rechargeable battery with a voltage of less than 2V. Check here. A practical DC voltmeter is shown in below figure. Hence, it can be used to measure the DC voltages from zero volts to 10 volts. As the name suggests, AC voltmeter measures the AC voltage across any two points of an electric circuit.
A practical AC voltmeter is shown in below figure. Hence, it can be used to measure the AC voltages from zero volts to volts. As the name suggests, ammeter is a measuring instrument which measures the current flowing through any two points of an electric circuit.
The unit of current is ampere and the measuring instrument is meter. Different types of resistors can be defined according to their function,size,characteristics etc. Resistors are divided in to Fixed Resistors and Variable Resistors. Variable Resistors, on the other hand, have a variable resistance that can either be changed manually or controlled by external factors like Light Dependent Resistor LDR or Thermistor.
Below image shows different types of resistors available. The second important passive components is a capacitor, a device that stores energy in the form of electric field. Most capacitors consists of two conducting plates that are separated by a dielectric material. The other applications of capacitors are filters, timing circuits, power supplies and energy storing elements. If capacitors store energy in the form of electric field, then inductors are devices that store energy in the form of Magnetic Field.
Inductor is nothing but a wire that is wound in the form of a coil. Inductor is widely used in AC equipment like filters, chokes, tuned circuits etc. The core around which the coil is wound i.
Inductors opposes the change in electric current through them and the changes in current will result in induction of voltage. When it comes to designing electronic circuits, testing and measuring various parameters like current, voltage, frequency, resistance, capacitance, etc.
The most reliable Test Equipment for observing continuously varying signals is an Oscilloscope. With the help of an Oscilloscope, we can observe the changes in an electrical signal like voltage, over time. Oscilloscopes are used in a wide range of field like Medical, Electronic, Automobile, Industrial and Telecommunication Applications. A multimeter is a combination of Voltmeter, Ammeter and Ohmmeter.
They provide an easy way to measure different parameters of an electronic circuit like current, voltage etc. Multimeters can measure values in both AC and DC. Earlies Multimeters are Analog and consists of a pointing needle. DMMs are available as handheld devices as well as bench devices. A Multimeter can be very handy in finding basic faults in a circuit. A Signal Generator, as the name suggests, generates a variety of signals for testing and troubleshooting electronic circuits.
