You can desolder pins by using a desoldering pump where the desoldering pump swallows the molten solder. Desolder the connections where electronic components are connected to the circuit board to salvage or replace them. Using a desoldering pump is one of the most pleasant ways to desolder a component. A desoldering pump is simply a high-pressure vacuum pump with a compact … [Read more...] about How To Desolder Pins

What Is Inductive Reactance
Inductive reactance is the resistance offered by the inductor in an AC circuit to the flow of ac current. XL is the symbol for it, and it's measured in ohms. Lower frequencies have a low inductive reactance, while higher frequencies have a greater one. For constant DC current, however, it is negligible. What Is Inductive Reactance The inductive reactance of a coil … [Read more...] about What Is Inductive Reactance
Reactance vs Resistance
Resistance is an effect offered by a resistor that opposes the current while reactance is the effect offered by a capacitor or inductor that opposes the change of current. The basic characteristic of resistance and reactance in an electrical circuit is that they restrict current flow. But the main difference between them is that resistor is a property that restricts the flow … [Read more...] about Reactance vs Resistance
555 Touch Sensor
How to make a touch sensor? Here is a simple DIY touch sensor circuit diagram using 555 timer monostable mode. The touch switch is only a conducting metal sheet that acts as a touch sensor. The 555 touch switch is not a touch capacitive sensor; it is only a metal touch sensor button. Using this you can turn on and off devices with a single … [Read more...] about 555 Touch Sensor
How to Make A 75 To 300 Ohm Matching Transformer
By wrapping some wires around a toroidal core, you can make a 75 to 300 Ohm matching transformer. It will cost you no more than $5. It will cost you nothing if you can find a few copper wires and a core in your house. The amount of time it takes is determined by your level of skill. It may take some time to follow the procedures correctly if you are trying out a project … [Read more...] about How to Make A 75 To 300 Ohm Matching Transformer
